After Border Patrol agents or OFO officers apprehend noncitizen family units, they are to interview each individual, using interpreters if needed, and collect personal information such as their names, countries of nationality, and age. Agents and officers also collect biometric information, such as photographs and fingerprints, from certain individuals, including those in family units. Border Patrol agents and OFO officers use fingerprints to run records checks against federal government databases to determine whether individuals have any previous immigration or criminal history. Agents and officers are to enter information about the individuals in the appropriate automated data system as soon as possible, in accordance with CBP policy. According to Border Patrol and OFO officials, if noncitizens are determined to be ineligible for admission into the United States, agents and officers must determine whether to place them, including those arriving in family units, into full or expedited immigration removal proceedings, consistent with the Immigration and Nationality Act. In full removal proceedings, individuals have the opportunity to present evidence to an immigration judge to challenge their removal from the country and apply for various forms of relief or protection, including asylum. In expedited removal proceedings, the government can order individuals removed without further hearing before an immigration judge unless they express the intent to apply for asylum or a fear of persecution or torture if returned to their home country. Most arriving family units are eligible to be placed into expedited removal proceedings, with certain exceptions, according to Border Patrol and OFO officials. A 2015 CBP policy requires CBP’s agents and officers to record such decisions for each family unit member in agency data systems. Further, Border Patrol agents and OFO officers print copies of the information they enter into data systems to create a paper file, known as an “A-file,” for each family unit member they apprehend. One of the key required DHS forms in the A-file is Form I-213, Record of Deportable/Inadmissible Alien (Form I-213). Among other things, this form captures biographic information and includes a narrative section for agents and officers to capture details about the circumstances of the apprehension. According to Border Patrol and OFO headquarters officials, each family unit member’s A-file is reviewed and approved by a supervisor. If CBP or ICE determines that a family separation is warranted, agents or officers process the child or children as UAC, according to Border Patrol, OFO, and ICE officials. ICE’s Office of Enforcement and Removal Operations is generally responsible for transferring these children, including those separated from a parent, as appropriate, to ORR. Under the Trafficking Victims Protection Reauthorization Act of 2008, children must be transferred to ORR within 72 hours after determining that they are UAC, except in exceptional circumstances. Table 1 provides additional details about DHS and HHS roles in processing family units. DHS officials told us that CBP typically holds family units together for a limited time before transferring them together to ICE, in accordance with CBP policy. During that time, agents and officers decide on a case-by- case basis whether to place each family unit in expedited or full immigration proceedings, according to Border Patrol and OFO officials. Individuals, including family unit members, placed in expedited removal proceedings and who express a fear of persecution or torture are generally subject to mandatory detention under the Immigration and Nationality Act pending a final credible fear determination. As a result, Border Patrol and OFO officials stated that its agents and officers typically determine whether ICE has space in its family residential centers before processing family units into expedited removal proceedings. From June 2014 through October 2019, ICE, during various periods, operated four family residential centers in Texas, Pennsylvania, and New Mexico for family units who may be subject to removal while they await the resolution of their immigration cases or who have been ordered removed from the United States. As of October 2019, ICE maintains three family residential centers—in Dilley, Texas; Karnes City, Texas; and Leesport, Pennsylvania—with a cumulative capacity of 3,326 beds. For information about these facilities, see table 2. CBP has historically separated children apprehended in family units from their parent(s) in specific circumstances, such as if the parental relationship could not be confirmed, if there was reason to believe the adult was participating in human trafficking, or if the parent was otherwise a threat to the safety of the child. As we reported in October 2018, ORR officials began observing an increase in the percentage of children in its care who were separated from their parents beginning in 2017. ORR officials stated they saw a continued increase in separated children in their care in the first few months of calendar year 2018. In April 2018, the U.S. Attorney General directed federal prosecutors to implement a zero-tolerance policy along the southwest border for immigration offenses and to accept all improper entry cases referred for prosecution to the extent practicable. According to DHS officials, after the Attorney General’s April 2018 memo, CBP began referring a greater number of adults apprehended at the border to the Department of Justice for criminal prosecution, including parents who were apprehended with minor children. CBP generally then separated the family unit, and after processing the children as UAC, CBP transferred them to ORR custody. According to CBP headquarters officials, the goal of the zero tolerance policy was to deliver a consequence to those crossing the border illegally by charging and convicting them of a crime, specifically a criminal conviction for improper entry, which is generally a misdemeanor. This could then lead to escalating criminal consequences for subsequent apprehensions, since noncitizens—in this case, adults in family units— entering the United States illegally for a second time could be charged with illegal reentry after removal from the United States, a felony offense. On June 20, 2018, the President issued an executive order directing that alien families generally be detained together. On June 26, 2018, a federal judge ruled in the Ms. L. v. ICE case, which was filed by the American Civil Liberties Union on behalf of certain parents (referred to as class members) who had been separated from their children. The June 2018 court order stated that certain separated parents must be reunited with their minor children, barring certain disqualifying criteria. On June 27, 2018, the CBP Commissioner issued a policy memorandum to provide direction on complying with the court order, to include potential reasons why a family separation may still be warranted. Figure 1 describes key actions since the Attorney General’s April 2018 memo that have influenced how DHS determines when family separations are warranted. On July 10, 2018, the court approved reunification procedures for the class members covered by the June 2018 court order. At that time the approved class included those adult parents separated from their children by DHS whose children were in ORR custody as of June 26, 2018, barring certain disqualifying criteria. Subsequently, on March 8, 2019, the court ordered an expansion of the class members to include all adult parents, subject to the same disqualifying criteria, who entered the United States at or between designated ports of entry on or after July 1, 2017, and were separated from their children by DHS. As of January 15, 2020, the government provided to the plaintiffs 11 lists identifying a total of 1,556 children of potential expanded class members. This brought the total number of possible separated children of potential class members to 4,370. CBP data indicate that the number of CBP apprehensions of family unit members was greater in the first two quarters of fiscal year 2019 than in all of fiscal year 2018. In addition, apprehensions of family unit members increased from approximately 22 percent of all southwest border apprehensions in fiscal year 2016 to approximately 51 percent of all such apprehensions in the second quarter of fiscal year 2019. The data also indicate that the majority of CBP apprehensions of family unit members were Central American nationals and the majority of apprehensions of children in family units were for children under the age of 12. Further, the data indicate that CBP placed family unit members in full removal proceedings before immigration courts at an increasing rate, and most were released into the United States to await their immigration court proceedings. Finally, CBP data indicate that CBP separated at least 2,700 children from their parents from April 2018 through March 2019. CBP data indicate that the number of apprehensions of family unit members along the southwest border increased from about 120,400 apprehensions in fiscal year 2016 to about 160,400 apprehensions in fiscal year 2018. Further, CBP apprehensions of family unit members reached about 213,400 during the first two quarters of fiscal year 2019 alone—approximately a 33 percent increase over the entire previous fiscal year. Cumulatively, along the southwest border, CBP apprehensions of family unit members reached about 599,000 apprehensions from fiscal year 2016 through the second quarter of fiscal year 2019 (see fig. 2). As shown in figure 3, CBP data indicate that apprehensions of family unit members grew from about 22 percent of total southwest border apprehensions in fiscal year 2016 to about 51 percent of such apprehensions during the first two quarters of fiscal year 2019. CBP data indicate that, during this period, OFO apprehensions of family unit members at U.S. ports of entry accounted for approximately 24 percent of all such CBP apprehensions. Border Patrol apprehensions of family unit members between ports of entry accounted for approximately 76 percent of all such CBP apprehensions. About 63 percent of CBP’s total family unit member apprehensions occurred in just three Border Patrol sectors in Texas and Arizona (see fig. 4). CBP data indicate that most apprehensions of family unit members from fiscal year 2016 through the second quarter of fiscal year 2019 were of Central American nationals and that the majority of children in family units were under the age of 12. Figure 5 shows that from fiscal year 2016 through the second quarter of fiscal year 2019, the vast majority of these apprehensions—about 82 percent—were nationals of Guatemala, Honduras, or El Salvador. Additionally, about 10 percent of apprehensions of family unit members were of Mexican nationals and approximately 7 percent were nationals of other countries. From fiscal year 2016 through the first two quarters of fiscal year 2019, CBP apprehensions of children in family units totaled approximately 327,600. About 72 percent of these apprehensions were of children under the age of 12 when apprehended by CBP, and about 32 percent were under age 5 (see table 3). Border Patrol also maintains information in its data system that allowed us to analyze the composition of family units, that is, whether the family unit was headed by a male or female and how many children were in the family unit. Most family units apprehended by Border Patrol—about 85 percent—consisted of a single parent travelling with a single child. Most family units were led by a single female in fiscal year 2016; however, the number of households led by single males increased and, for the first two quarters of fiscal year 2019, accounted for almost half of the family units Border Patrol apprehended. Appendix II contains additional information about the composition of family units, including the immigration history of adult family members. From fiscal year 2016 through the first two quarters of fiscal year 2019, CBP placed an increasing percentage of family unit members into full removal proceedings. Specifically, CBP data indicate that around 46 percent of all apprehensions of family unit members in fiscal year 2016 resulted in the family unit members receiving Notices to Appear before an immigration court, which initiate full removal proceedings; around 88 percent received Notices to Appear during the first two quarters of fiscal year 2019. Conversely, CBP data indicate that CBP placed a decreasing percentage of all apprehensions of family unit members into expedited removal proceedings during this period. Specifically, the percentage declined from about 42 percent of all apprehensions of family unit members in fiscal year 2016 to about 6 percent during the first two quarters of fiscal year 2019. CBP officials stated that, since the volume of family units apprehended at the border increased in 2018, they have placed fewer family unit members into expedited removal proceedings, for which detention is generally mandatory, due to limited space for family units in ICE’s family residential centers. Department of Homeland Security’s (DHS) Migrant Protection Protocols In January 2019, DHS introduced the Migrant Protection Protocols, also referred to as the “Remain in Mexico” program, at selected ports of entry and, as of March 2019, within certain Border Patrol sectors. Under this policy, CBP issues eligible individuals, including family unit members, Notices to Appear before an immigration court, thereby initiating full removal proceedings. After CBP agents and officers complete processing duties, DHS officials stated that CBP returns the individuals to Mexico to await their court proceedings, rather than releasing them into the interior of the United States. According to CBP officials, through the end of fiscal year 2019, CBP processed approximately 44,200 individuals—among which about 30,100 individuals, or 68 percent, were family unit members—using the Migrant Protection Protocols. While ICE generally has the authority to detain individuals for the duration of their full removal proceedings, CBP and ICE officials stated that ICE faces constraints that typically prevents it from doing so for family units. Specifically, the limited amount of space at family residential centers is reserved for those family units placed in expedited removal. Therefore, according to ICE and CBP officials, with few exceptions, during the period of our review, family units placed into full removal proceedings were released into the United States to await their court proceedings. According to ICE officials, even if there was more detention space for family units, there are other constraints that would prevent ICE from detaining family unit members (placed into full removal proceedings at any point) for the duration of their court proceedings. Specifically, children may generally only be held in federal immigration detention for 20 days pursuant to the Flores Agreement. Due to the duration of full removal proceedings, most full removal proceedings take longer than 20 days. According to Border Patrol and OFO data, CBP separated at least 2,700 children from April 19, 2018, through the second quarter of fiscal year 2019. As we discuss later in this report, CBP may have separated additional children from their parents during this period and not recorded this information in its data systems. As a result, we are reporting approximate, rounded figures on family separations. Specifically: Border Patrol updated its data system to track family unit separations on April 19, 2018, and issued written guidance to its agents about these changes on May 7, 2018, and August 2, 2018. From April 19, 2018, through March 31, 2019, Border Patrol data indicate that agents separated at least 2,670 children. OFO updated its data system to track family unit separations on June 26, 2018, and issued guidance on these changes to its officers on June 29, 2018. From June 30, 2018, through March 31, 2019, OFO data indicate officers separated at least 30 children. As shown in table 4, CBP data indicate that the number of family unit separations was highest between April 19, 2018 and June 27, 2018, due to DHS’s response to the U.S. Attorney General’s April 2018 zero tolerance policy (see table 4). CBP data also indicate that a small percentage of all children that arrived in family units—fewer than 2 percent—were separated from their parents during these time frames. Appendix II provides additional information about the characteristics of family units separated by CBP. Border Patrol and OFO data indicate that the reasons for these family unit separations varied. Regarding Border Patrol, as of April 19, 2018, agents were able to record a family separation and select from options to explain the reason for it in Border Patrol’s automated data system. Border Patrol data indicate that the reasons that 97 percent of the adults and children separated from April 19 through June 27, 2018, were because agents referred the parent to the Department of Justice for criminal prosecution on charges for criminal history or other reasons, or due to a prior immigration violation(s) and a removal order. Table 5 shows the reasons for family separations indicated in Border Patrol data from April 19, 2018 through March 31, 2019. Regarding OFO, as of June 30, 2018, officers were to record the reason for any family unit separation with the child’s record in OFO’s automated data system. From June 30, 2018 to March 31, 2019, OFO data indicate that about 50 percent of adults and children were separated due to the criminal history of the adult or a child safety concern. Table 6 shows the reasons for family separations indicated in OFO data from June 30, 2018 through March 31, 2019. Since 2015, Border Patrol and OFO have issued policies and updated procedures regarding the information to be collected about family units and family separations, increasing the amount of data collected for family units. For example, Border Patrol and OFO have updated their data systems to better track the number of individuals apprehended as part of family units and to record when and why family separations occur. Specifically, Border Patrol updated its data system in October 2015 to track whether individuals were apprehended as members of a family unit and again in 2018 to track family separations. On October 2, 2015, the Chief of the Border Patrol issued policy guidance requiring agents to process family units together in its data system with a unique identifier called a “family unit number,” which links the records of parents and children apprehended together. Border Patrol updated its system on April 19, 2018 and on August 2, 2018, to track the number of separated adults and children and the reasons for the separations, and issued guidance to its agents about these updates. New Border Patrol agents also receive mandatory training on, among other topics, recording information into agency data systems, including procedures specific to family units. OFO updated its data system to track whether children under the age of 18 arrived as part of a family unit and whether they were separated from a parent (or other family member) with whom they arrived. OFO headquarters officials stated the updates were made during fall 2015. On June 29, 2018, OFO issued a policy memorandum that, among other things, required officers to track family separations in OFO’s data system, and announced system updates to allow officers to select a separation reason. This and subsequent data system updates allowed officers to identify which separations were temporary (in which the family was reunited while still in OFO custody), and which were permanent (resulting in OFO referring a child to ORR), according to OFO officials. All OFO officers hired as of March 2011 receive mandatory training on certain processing procedures, including recording information into agency data systems. As of October 2019, OFO’s data system does not have the capability— such as by using a family unit number—to link the records of noncitizen parents and children apprehended together and thus cannot determine the total number of adults involved in family separations. OFO is implementing a new data system across all ports of entry that includes a function to link the records of parents and children in family units using a unique identifier. According to OFO officials, OFO began developing the new data system in August 2017 and, as of October 2019, has implemented it at 90 ports of entry, none of which are land ports of entry along the southwest border. In June 2019, OFO officials stated they planned to train OFO officers on the new data system at land ports of entry along the southwest border in late summer 2019, but as of October 2019 that timeline had been delayed due to the high volume of family units apprehended that summer. According to OFO headquarters officials, they expected to deploy the new system to locations along the southwest border on an ongoing basis as conditions allow. It is too soon to determine whether the new data system will enable OFO to link children apprehended at ports of entry to their parents and allow for OFO to track the total number of family members separated in its aggregated data. It is also too soon to determine whether the new system will provide OFO officers with more readily available information that could help reunify separated family units, if necessary. Since October 2015, some Border Patrol and OFO documents have included inconsistent guidance on how agents are to define a family unit for processing purposes. CBP’s 2015 policy defines a family unit to include one or more non-U.S. citizen juvenile(s) accompanied by his or her parent(s) or legal guardian(s), which Border Patrol agents confirmed is the agency’s official definition that should guide how its agents process family units. However, as shown in table 7, certain Border Patrol policy documents since October 2015 have also stated that “all members of the apprehended family unit must be non-criminal and/or non-delinquent and have no history of violence or substance abuse.” As a result, individuals in family units that Border Patrol considered criminal, delinquent, or to have a history of violence or substance abuse may not have been included in Border Patrol’s aggregated data on apprehended family units and family separations (once the agency began tracking separations in April 2018), because agents did not define and process them as family units. We raised these inconsistencies to Border Patrol headquarters officials in April 2019, and they acknowledged that certain policy and training documents contained inaccurate definitions and guidance, which could have led some agents to process certain parents and children separately, without a family unit number to link their records. Specifically, they stated that the language requiring that “all members of the family unit must be non-criminal and/or non-delinquent, and have no history of violence or substance abuse” should not be included in Border Patrol’s definition of a family unit. In addition, officials noted that any guidance directing agents to process a family unit separately in the data system, as a single adult and UAC rather than linked together with a family unit number, due to a planned prosecution referral is inconsistent with Border Patrol’s processing procedures. They stated this was an oversight and not an intentional change to the agency’s official definition as indicated in CBP’s 2015 policy. The Border Patrol headquarters officials were unsure of how often the inconsistent definitions and guidance may have led agents to incorrectly process family units. On the basis of our analysis of Border Patrol and ORR data, we found evidence that agents processed some family units separately, as single adults and UAC, without a family unit number or record of their separation. Specifically, for children apprehended from June 28, 2018 through March 31, 2019, we compared ORR numbers on UAC involved in family separations to Border Patrol apprehension data on separated children. During that period, ORR records indicated that DHS separated 396 children, while Border Patrol apprehensions data indicated that it separated 180 children. Border Patrol headquarters officials confirmed that the discrepancy we identified between Border Patrol data and ORR records may be attributable, in part, to the agents processing family units incorrectly and separately, without assigning them a family unit number. To better understand the discrepancy between the ORR and Border Patrol data, we selected a random, nongeneralizable sample of 40 ORR records for UAC involved in family separations from June 28, 2019 through March 31, 2019, and found matches for each of the children in Border Patrol apprehensions data. In 14 of the 40 selected ORR records, Border Patrol data indicated the agent had not recorded the child as a member of a family unit linked to a parent’s record with a family unit number. Thus, Border Patrol agents had not recorded the subsequent separation when agents referred the children to ORR as UAC. A Border Patrol headquarters official stated that it is also likely that some agents were processing family units separately, rather than linking them with a family unit number, from May to June 2018 when agents were referring parents for criminal prosecution in response to the April 2018 zero- tolerance policy. The official stated that agents may not have realized that assigning a family unit number was necessary to track the separation in the Border Patrol data. During the course of our audit, we discussed this issue with Border Patrol and, as a result, Border Patrol issued new guidance to its sectors in April 2019 with an updated definition of family units consistent with CBP policy. According to Border Patrol officials, Border Patrol also removed previous policy documents, with the incorrect definitions and guidance, from a website accessible to all Border Patrol agents. However, as of late November 2019, Border Patrol training materials still direct agents to process a parent and child separately, without a family unit number, if a family member has a history of criminality, delinquency, violence, or substance abuse, or if Border Patrol plans to prosecute the parent. This definition and guidance, inconsistent with CBP policy, has been included in training provided to all new agents at Border Patrol’s basic training program since at least October 2017. According to officials from the Border Patrol Academy, which is responsible for updating training materials in coordination with program officials, they plan to update the training materials in 2020. In the meantime, since September 2019, the Border Patrol Academy has been providing trainees with a handout that includes a definition of family units consistent with CBP policy. Regarding OFO, we also found that since 2012, training materials for new officers have included a definition of a family that is inconsistent with CBP and OFO policy. Specifically, OFO training materials issued in January 2012—and in use as of November 2019—define a “family group” as “a juvenile who is accompanied by closely related adults (parent, grandparent, brother, sister, or legal guardian)” and considers the juvenile to be UAC if “the juvenile is accompanied by relative(s) not closely related.” The training document does not include a definition for “family unit.” However, other key OFO policy documents issued subsequently define family units in a way that is consistent with CBP policy—namely, a February 2016 memo on processing family units in OFO’s data system and a June 2018 memo on tracking family separations. We raised the discrepancy in OFO’s training materials with OFO headquarters officials in June 2019. OFO officials were unsure whether this definition had led any officers to incorrectly process adults and children as family units when they did not meet CBP’s definition of a family. OFO headquarters officials stated the training materials were inconsistent with CBP and OFO policy, and officials from CBP’s Office of Training and Development stated they updated the training materials and provided them to OFO in late November 2019. However, as of December 2019, CBP had not provided us with the updated materials to verify that the revisions are consistent with CBP policy. Standards for Internal Control in the Federal Government states that management should design control activities, including by providing the right training tools to achieve operational success. In addition, in GAO’s Guide for Strategic Training and Development Efforts, we have reported that senior managers need to continually observe and assess how changes, such as in policies or practices, may affect the agency’s training needs. This is one way, among others, to help ensure that the agency has a framework to achieve its mission. Border Patrol and OFO officials acknowledged the need to update training materials with definitions and guidance, consistent with CBP policy; they explained that they had not yet done so due to the considerable time and coordination it requires. Issuing updated training materials that reflect CBP policy would help CBP ensure that Border Patrol agents and OFO officers are processing family units appropriately and tracking all separations. CBP has policies and procedures for assessing the validity of family units, but does not have written guidance to help ensure that these cases are well documented, as required by CBP policy. CBP has policies and procedures for assessing the validity of family unit relationships. During processing, Border Patrol and OFO officials said that it is standard practice for agents and officers to assess whether (1) adults and children apprehended together meet CBP’s definition of a family unit and (2) whether agents and officers deem the claimed family relationships to be potentially invalid. A CBP policy issued on June 27, 2018, states that “fraudulent claims of family relationships” should be processed under “current CBP policies and procedures.” In practice, this means that agents and officers are to consider the validity of family relationships on a case-by-case basis with the information they have available at that time, according to Border Patrol and OFO headquarters officials. For example, these officials stated that agents and officers review any available documentation, such as birth certificates, presented by individuals; monitor interactions between adults and children to assess whether interactions are typical of that of a parent and child; and generally use their law enforcement training, such as interviewing skills, to help assess the validity of family relationships. Border Patrol and OFO officials noted that, in some instances, individuals have admitted to falsely posing as a family, while other times agents and officers have to make an assessment based on the totality of the information available to them. In accordance with CBP policy, Border Patrol and OFO are to generally hold individuals no longer than 72 hours, so Border Patrol and OFO officials stated they must assess the validity of the family units based on available information during the time they have individuals in custody. According to Border Patrol and OFO officials and documents, they have observed cases in which (1) a family unit claims a child is under 18 years of age, but agents suspect the child is older, and thus they do not meet CBP’s definition of a family unit, or (2) the adult claims to be the parent, but Border Patrol has concerns that the adult is another family relation, such as an aunt or older sibling, or the adult is not related to the child at all. In June 2019, the Acting Secretary of Homeland Security testified that CBP identified “almost 4,800 migrants this year” in family units that CBP agents and officers determined to be “fraudulent” in nature. In cases when Border Patrol agents or OFO officers, with approval from their respective supervisors, assess that the relationship of a family unit may not be valid, the child is to be processed as a UAC and transferred to ORR. Specifically, according to Border Patrol and OFO officials and documents, agents and officers are to indicate in their data systems that the adult and child were separated and the reason why, and then refer the child to ORR as a UAC. For Border Patrol, this process involves removing the family unit number linking their records. Border Patrol and OFO do not consider these cases to be family separations, since CBP assessed that the individuals may not be part of a valid family unit. According to CBP’s June 2018 policy, if a child arrives with an adult claiming to be the child’s parent, a supervisory-level OFO or Border Patrol official must give approval before an agent or officer transfers a child to ORR as a UAC. According to Border Patrol and OFO headquarters officials, if an adult wishes to appeal CBP’s assessment, the adult may raise the issue with ICE officers when transferred to an ICE detention facility. Border Patrol headquarters officials told us that its agents generally explain to the adults that Border Patrol is processing them separately from the children they arrived with due to concerns about the validity of the family relationship. OFO headquarters officials told us that OFO does not generally notify adults when processing the adults and children in potentially invalid family units because they stated they do not want to jeopardize the safety of the child if they suspect fraud, smuggling, or trafficking. According to Border Patrol and OFO officials, they may separate adults and children who they are concerned might not be valid family units to ensure the safety of the child—for example, if agents and officers cannot be certain that the child has not been a victim of trafficking by the accompanying adult. Further, Border Patrol, OFO, and ICE officials stated that ICE and ORR are better positioned to further investigate these cases if an adult refutes CBP’s assessment that the family unit was invalid, because CBP must generally hold individuals for a short period. In addition, ICE and ORR are the agencies most involved in reunifying family units, when appropriate. CBP began tracking the number of potentially invalid family units in 2018. On April 19 and June 29, 2018, Border Patrol and OFO, respectively, issued guidance about updates to agency data systems and issued guidance to enable agents and officers to record potentially invalid family units. That is, if the appropriate Border Patrol and OFO managers give approval, agents and officers separate potentially invalid family units, and record the separation and the reason for it in agency data systems, according to Border Patrol and OFO officials and documents. More specifically: Border Patrol agents are to delete the family unit number from the parents’ and children’s records, and indicate the reason from options that include “child is over the age of 18,” “no family relationship,” or “no family relationship–prosecuted.” OFO officers are to indicate that a child was separated from the adult with whom they arrived, and are to indicate the reason as “fraudulent relationship.” Border Patrol and OFO officials noted observing cases of potentially invalid family units, and Border Patrol data indicate an increase in the number since Border Patrol began tracking the cases in April 2018. Specifically, during our fall 2018 visits to ports of entry and border stations in Texas and California, Border Patrol and OFO officials stated they have observed suspected or confirmed cases of adults falsely claiming to be a child’s parent, including occasional instances of seeing the same child apprehended multiple times, but with different adults claiming to be their parents. From April 19, 2018 through March 31, 2019, CBP data indicate that CBP referred at least 921 children to ORR (918 by Border Patrol and 3 by OFO) due to CBP’s concerns that the family relationships were potentially invalid. During the same period, Border Patrol data also indicated that 2,245 adults were processed separately from the children with whom they were apprehended due to concerns about the validity of the family relationships. By comparison, Border Patrol data indicated that agents processed 256,743 adults and children in valid family units during this period. However, from July 1, 2018 through March 31, 2019, the number of individuals Border Patrol assessed as part of potentially invalid family units grew at a faster rate than the number of individuals apprehended in valid family units. Specifically, the average monthly increase in adults and children Border Patrol assessed to be in potentially invalid family units rose by about 70 percent per month, on average, during this period. Meanwhile, Border Patrol data indicate the rate of increase for adults and children in valid family units was about 53 percent per month, on average. However, some of the family units that CBP assessed to be potentially invalid are subsequently found to be valid, according to ORR and ICE officials. According to ORR officials and records of UAC involved in family separations from June 28, 2018 through June 28, 2019, ORR was aware of only 46 cases in which CBP referred a child to ORR care because CBP had assessed the family unit to be invalid. In at least 10 of those cases, the family was later determined to be valid and the child reunited with his or her separated parent, according to ORR officials, as of June 2019. Anecdotally, ICE headquarters officials stated that there are occasionally cases in which CBP referred a child to ORR because agents or officers assessed the family to be an invalid family unit, but ICE or ORR later determined the family was valid and eligible to be reunified. For example, ORR’s records on family separations included instances in which the validity of family relationships was determined through DNA testing. ICE officials stated that its officers are able to conduct additional research about the validity of family relationships, as needed, once an adult has been transferred to its custody and the child to ORR. However, ICE does not track how often potentially invalid family units are later assessed to be valid and reunited, and, therefore, could not provide an exact number of how often this has occurred. DHS and ICE officials have tracked the outcomes of some deployments of ICE officers to help CBP assess the validity of family relationships. Specifically, the Acting Secretary of Homeland Security testified before the Committee on Oversight and Government Reform in the House of Representatives on July 18, 2019 that CBP agents and officers referred 2,475 family unit members they suspected had invalid family relationships to go through an additional assessment by ICE officers who, among other training and skills, have specialized forensic interviewing skills. The ICE officers assessed 352 of the 2,475 individuals—approximately 14 percent—to be invalid family members. Additionally, an ICE official also testified before the Senate Committee on Homeland Security and Governmental Affairs on June 26, 2019, and described a May 2019 pilot that involved voluntary rapid DNA testing for some individuals. According to this official, 16 of the 84 family units tested, around 19 percent, proved not to be the parent of the child with whom they arrived. According to ICE officials, those family units it determined to have valid family relationships while still in CBP custody, based on the available evidence, remained together as a family unit and were not separated. On June 27, 2018, the CBP Commissioner issued a policy memorandum requiring that “fraudulent claims of parental or legal guardianship relationship” should be “well-documented to support such claims”; however, CBP does not have guidance to clarify how agents and officers are to fulfill that requirement. Border Patrol and OFO headquarters officials indicated that taking the aforementioned steps to record information in agency data systems meets the CBP policy requirement for documentation. In addition, according to Border Patrol and OFO officials, agents and officers also record details of the apprehension on the Form I- 213, which is required for all individuals. However, neither Border Patrol nor OFO has guidance about whether or what details about a family unit being assessed as potentially invalid should be included on the Form I- 213. Learning about the details of these cases and why CBP made its assessment is important to ICE officials in the event an adult refutes the assessment and ICE must take additional steps to determine the validity of the family relationship. ICE officials can view the information CBP agents and officers record on the Form I-213, since ICE officers can access the form in a database it shares with CBP. However, the headquarters official responsible for coordinating ICE’s family and juvenile programs stated that the level of detail included in the forms varies by location and the narrative often does not include details about the reason why CBP considered a family unit potentially invalid. ORR officials also stated this information would be helpful to ORR because it may be relevant to the decisions ORR staff make for UAC, such as selecting sponsors. ORR intake staff told us that the documents they receive from CBP accompanying UAC referrals typically do not contain narrative information about agents’ or officers’ concerns about potentially invalid family relationships. While CBP tracks cases on potentially invalid family units in its data systems, this tracking does not (1) document the circumstances to support the assessment of invalidity or (2) provide complete and timely information for ORR and ICE to help them to fulfill their responsibilities, including to review cases in which CBP initially determined a family to be invalid but further investigation is needed. Rather, CBP’s data systems only track the assessment of invalidity by allowing agents to select that as a reason from a set of options, but do not track the circumstances to support that assessment. However, CBP policy directs that these cases be “well-documented to support such claims.” Standards for Internal Control in the Federal Government state that management should use quality information to achieve the entity’s objectives. In doing so, management should identify the information needed to achieve objectives and address risks, and should consider the expectations of both internal and external users. Providing guidance on what narrative information Border Patrol agents and OFO officers are to document on a child’s and the accompanying adult’s Forms I-213 about potentially invalid family units could help better ensure that the events are well-documented to support such assessments, in accordance with CBP policy. Further, this could help ensure that ICE and ORR officials have relevant details they need to make decisions for adults and children in their custody, including reuniting valid family units, where appropriate, before adults are removed from the United States. CBP, Border Patrol, and OFO have developed policies and procedures for those agents and officers responsible for recording and approving family separations; however, Border Patrol and OFO do not have sufficient controls to ensure (1) Border Patrol agents are accurately and consistently recording family separations in their data systems, (2) Border Patrol and OFO’s data systems accurately capture separation reasons that are consistent with CBP policy, and (3) required forms include sufficient details about the circumstances of the separations. Regarding policies and procedure for family separations, according to CBP’s June 2018 policy, a Border Patrol watch commander, or equivalent position, must approve every family separation. Border Patrol and OFO officials told us that higher-level officials, such as Border Patrol sector chiefs or Port Directors, are often involved in decisions to separate family units. A 2015 CBP policy requires that agents and officers record family separations in agency data systems. Further, after updating data systems to track family separations in 2018, as previously described, Border Patrol and OFO issued written guidance to agents and officers with specific instructions on how to record family separations in its data systems. For example, Border Patrol issued guidance about how to record family separations in its data system in May 2018, August 2018, and April 2019. In addition, Standards for Internal Control in the Federal Government state that management should use quality information to achieve the entity’s objectives, and identify the information needs to address risks. In doing so, managers should also consider the expectations of both internal and external users when collecting information. Further, changes in conditions affecting the entity and its environment often require managers to revise the internal control system, on a timely basis to maintain effectiveness. Our analysis of Border Patrol and ORR data indicates that Border Patrol agents have not accurately and consistently recorded family separations in the data systems. Specifically, we reviewed a random, nongeneralizable sample of 40 ORR records for UAC involved in family separations between June 28, 2018, and March 31, 2019 and found matches for all 40 of the children in Border Patrol apprehensions data. Among the 40 records, we identified cases in which agents had not documented the family separation in Border Patrol’s data system, as required by CBP and Border Patrol policy. Specifically, Border Patrol data indicated the agent had not processed the separation in the Border Patrol data system for 10 of the 40 UAC involved in family separations. That is, in these cases, Border Patrol agents processed the parents and children together with a family unit number, but did not take the necessary steps in the system to separate them and document the reason why the separation occurred. We shared the results of our analysis with Border Patrol officials, and these officials acknowledged that the discrepancy between Border Patrol and ORR data on family separations may be attributable, in part, to human error—that agents had not correctly recorded family separations in Border Patrol’s data system. However, the officials were unsure of the extent of the problem. Thus, it is unclear whether Border Patrol has accurate records of all separated parents and children in its automated data system. Border Patrol officials stated that data entry errors may have grown with increased processing demands and strained resources faced by Border Patrol as the volume of family units apprehended increased in fiscal years 2018 and 2019. However, as mentioned, federal internal control standards provide that changes in conditions—such as increased processing demands agents faced during periods of increased apprehensions of family units—often require managers to revise the internal control system. Developing and implementing additional controls to ensure that Border Patrol agents accurately record family separations in the data system, consistent with CBP and Border Patrol policies, would better enable Border Patrol to maintain complete and accurate information on all family separations. For example, an additional control could be to require Border Patrol or OFO managers conducting supervisory review of each apprehension to check that family separations have been accurately recorded in the data system. CBP, Border Patrol, and OFO have policies and procedures in place for those agents and officers responsible for approving family separations and recording the reasons in agency data systems. On June 27, 2018, the CBP Commissioner issued a memorandum to the Chief of the Border Patrol and to the Executive Assistant Commissioner of OFO to provide direction on complying with the June 26, 2018, federal court order in Ms. L. v. ICE that generally prohibits the government from separating parents from their children, to include potential reasons that may warrant continued family separations. Specifically, the memorandum states that separations may occur only for the following reasons: (1) the parent has criminal convictions for violent misdemeanors or felonies, (2) CBP plans to refer the parent for a felony prosecution, (3) the parent poses a danger to the child, or (4) the parent has a communicable disease. On June 29, 2018, OFO issued a policy memorandum reiterating the potential separation reasons included in CBP’s June 27, 2018 policy memorandum. According to Border Patrol headquarters officials, Border Patrol did not issue any further implementing guidance. Border Patrol and OFO officials stated that agents and officers are to use all available information to determine whether a family separation is warranted. Such information may include available birth certificates, personal observations of the family unit’s behavior, results of background checks for criminal and immigration history, and results from available medical assessments. In some instances, Border Patrol and OFO officials stated that agents and officers may not always have complete information, such as when a database indicates a parent’s arrest but does not indicate whether he or she was convicted of the charge, but that agents and officers are to weigh the totality of the circumstances. For situations in which agents and officers are unsure whether to separate a family, CBP’s policy states that agents and officers should contact their local Office of Chief Counsel for guidance. Although Border Patrol and OFO data systems allow agents and officers to select among options to indicate the reason for a family separation, the reasons available in the systems do not fully align with CBP policy. For example, Border Patrol’s data system does not include an option that indicates the parent poses a danger to the child—one of the reasons articulated in the Commissioner’s June 2018 memorandum. Table 8 shows how the separation reasons available in Border Patrol and OFO data systems compared with the potential separation reasons established in CBP’s June 2018 family separations policy. Border Patrol and OFO headquarters officials stated they were unsure why the separation reasons available in the data systems do not fully align with CBP policy on family separations, but stated that the data system reasons have an implicit link to CBP policy. They stated that Border Patrol and OFO officials review and approve each family separation to ensure it meets CBP policy. In addition, OFO headquarters officials stated that it issued guidance in June 2018 that reiterated CBP’s policy on potential reasons for family separations. However, as illustrated in table 8, it is sometimes not clear how separation reasons in Border Patrol’s and OFO’s data systems align with CBP policy. For example, Border Patrol’s option for “family member prosecuted for other reasons” does not provide enough information to determine whether Border Patrol is referring a parent for the prosecution of a felony, as required by CBP policy. Both Border Patrol and OFO have previously changed separation reasons in agency data systems, and in June 2019 Border Patrol officials stated they continue to analyze the need for updates. As of October 2019, these officials stated that Border Patrol and OFO do not have any current plans to update the separation reasons in their data system. CBP officials who conduct supervisory review of files and approve family separations rely, in part, on the information agents and officers record in Border Patrol and OFO data systems, in conducting reviews and sharing information, according to Border Patrol and OFO officials. Updating Border Patrol’s and OFO’s data systems to ensure that options for separation reasons clearly align with CBP policy could help ensure that CBP makes decisions about family separations in accordance with CBP policy and that data CBP collects reflects that. CBP’s policies related to family separations do not include written requirements that agents and officers record a description of the family separation. However, Border Patrol and OFO officials stated that they expect agents and officers to record the circumstances surrounding family separations on a narrative section of each family member’s Form I-213. Yet we found that Border Patrol agents are not consistently recording detailed information about family separations on the Form I-213—the official record of the apprehension. Specifically, we analyzed a nongeneralizable sample of Forms I-213 for family units whom Border Patrol separated and found that, for most of the family separation cases, one or more of the selected forms had missing or inconsistent information in the narrative descriptions. Specifically, we reviewed a sample of Forms I-213 for 23 family separation cases, involving 27 children and 25 parents. These separations occurred across each of the Border’s Patrol’s nine southwest border sectors between June 28, 2018 and March 30, 2019. In particular, we assessed (1) whether the forms included a reason for the separation, (2) whether the descriptions of the cases provided enough information to determine whether or not the reason met CBP policy, and (3) whether the information recorded for each separation case was consistent across the parents’ and children’s forms. On the basis of our review of the forms, we found there was missing or inconsistent information on one or more of the family members’ forms for 18 of the 23 separated family units. Specifically, we found for three of the 23 family separations, there was no indication that a separation had occurred on one or more of the family members’ forms; for 20 of the 23 family separations, all of the family members’ forms included some indication of a family separation; Seven of the 25 parents’ forms and seven of the 27 children’s forms did not contain a narrative description explaining why the separation occurred; and 17 of the 25 parents’ forms included sufficient narrative information to determine whether the separation met CBP policy; 12 of the 27 children’s forms included enough information to make that determination. In addition, even among those forms with sufficient information to determine whether the reason met CBP policy, we found inconsistencies. For example: Three parents’ and four children’s forms included information that implied that the parent could potentially present a danger to the child, but the actual separation reason noted on the form was something different, such as the parents’ criminal history. For example, the criminal history information provided on one parent’s Form I-213 included information about an arrest for kidnapping, but did not include evidence that the arrest resulted in a conviction, making it difficult to determine whether the separation aligned with CBP policy and, in particular, what reason the separation would fall under. For nine of the 23 family separations, the separation reason was listed as the parent’s criminal history on one of the family member’s forms, but there was missing or inconsistent information on the other family members’ forms. For example, in one instance, the father’s Form I- 213 indicated he had been convicted of sexually assaulting a 12-year- old child, but there was no separation reason and no information about the parent’s criminal history provided on the child’s form. According to ICE officials responsible for monitoring family separations, and reunifying family units where necessary, the narrative information on the Form I-213 is ICE officers’ primary source of information about the circumstances of a family separation. ICE officers need detailed information, according to officials, to help conduct additional research to confirm whether a separation was warranted or respond to requests for information from ORR. In addition, ORR officials told us that they would benefit from CBP recording certain information on a child’s Form I-213— such as the type and timing of a parent’s criminal conviction or whether the parent may pose a danger to the child—and sharing that information, to better inform ORR’s decisions about where and with whom to place UAC when they leave ORR custody. However, CBP has not issued guidance on what descriptive details surrounding family separations agents and officers are to record on the Form I-213, based on our review of CBP documents. In addition, Border Patrol officials stated that they do not have written guidance for agents about what information should be captured on the Form I-213. Conversely, OFO issued guidance stating that the Form I-213 must be annotated with the reason for the family separation, the name of the approving manager, and, at a minimum, the biographical information and “A-number”—a unique identifier for noncitizens apprehended by CBP—of the parent(s) and children. Border Patrol and OFO headquarters officials acknowledged that the level of detail documented on the Form I- 213 about separations may vary by agent or officer, and rely on their supervisory review process to ensure that family separations are consistent with CBP policy. Border Patrol headquarters officials attributed missing separation reasons or inconsistent information about the circumstances of the family separations on the Forms I-213 to multiple factors. Specifically, they acknowledged that Border Patrol has not issued guidance specifying what descriptive details agents should include on the forms, and does not have, for example, specific information that supervisors check for during their review of each individual’s file. In addition, Border Patrol headquarters officials noted that there have been great demands placed on Border Patrol agents to expedite processing during periods of high numbers of family units apprehended and crowding at Border Patrol facilities. However, as noted previously, federal internal control standards state that changes in conditions affecting the entity and its environment— like an increase of family units apprehended along the southwest border—often require management to change the entity’s internal control system, as existing controls may not be effective for meeting objectives or addressing risks under changed conditions. As of October 2019, Border Patrol and OFO had no plans to (1) implement additional controls to ensure that reasons for family separations are included on individuals’ Form I-213 or (2) issue guidance to agents and officers about what descriptive information about family separations they should record on the forms. Developing and implementing additional controls to ensure that Border Patrol agents and OFO officers include a reason for the family separations on the parent’s and child’s Forms I-213 could help CBP ensure its agents and officers are separating family units in accordance with CBP policy. For example, an additional control could be to require the Border Patrol or OFO manager reviewing the information recorded on the Form I-213 to check that certain information, such as the specific separation reason with relevant details, has been included. In addition, without additional guidance on what specific details Border Patrol agents and OFO officers are to include in the narrative information about the family separation events on the parent’s and child’s Forms I-213, ICE and ORR do not have complete or consistent information to use in determining when it may be necessary to reunify family units in accordance with the Ms. L. v. ICE court order. ICE has procedures for processing family units whom CBP apprehended and for releasing family units from ICE custody (see fig. 6). According to ICE field office officials, upon referral by CBP, ICE officers generally review the family unit’s files to ensure that CBP agents and officers completed the forms sufficiently and, if not, ICE officers can return the case to CBP. For example, ICE officers typically ensure that the appropriate family unit member signed his or her copies of paperwork provided by CBP. Additionally, according to ICE field office officials, ICE officers have the discretion to decline the transfer of a family unit that they determine is not suitable for detention in a family residential center or for release. When ICE accepts CBP’s referral of a family unit and receives custody from CBP, ICE officers are to enter information about each family unit member in ICE’s data system, both for family units that ICE plans to detain and those it plans to release. ICE’s data system pulls some information from CBP’s data systems. For example, ICE officers can find basic biographic information about individual family unit members apprehended by Border Patrol by searching for an individual by his or her “A-number,” a unique identifier. In addition, ICE officers are to enter new information, such as the location(s) where officers detained or released the individual family unit members and the documents officers served to them, among other things. For information about the family unit members that ICE detained at its family residential centers, see appendix II. Family units placed into expedited removal by CBP and detained in ICE family residential centers—who express an intention to apply for asylum, a fear of persecution or torture, or a fear of return—undergo screenings conducted by an asylum officer. These screenings occur during detention and are to determine whether one or more family unit members have a credible fear of persecution or torture. The outcome of the screening (and review by an immigration judge, if requested after the screening) determines whether ICE will remove the family unit from the United States or release the family unit into the interior of the country to pursue immigration relief or protection in full immigration proceedings. Additionally, as stated previously, children may generally only be held in federal immigration detention for 20 days pursuant to the Flores Agreement. Thus, if members of the family unit do not receive a credible fear determination within 20 days, ICE generally releases the family unit into the interior of the United States with a notice to appear before an immigration court, which initiates full immigration proceedings. From fiscal year 2015 through fiscal year 2018, ICE data indicate that 99 percent of family unit members who were detained in one of ICE’s family residential centers were subsequently released by ICE into the interior of the United States. For additional information about the outcomes for family unit members detained in ICE family residential centers, see appendix II. According to ICE headquarters and field office officials, while a family unit is at a family residential center, ICE officers typically assist family units with their post-release plans by asking heads-of-household to identify contacts in the United States, such as relatives, that the family unit can stay with after leaving ICE custody. These contacts pay for the family unit’s travel expenses if the family cannot purchase bus tickets, for example, and ICE officers help coordinate these plans and typically drive the family unit to the bus station upon release, according to ICE officials. For family units who are not placed in a family residential center, ICE’s procedures for assisting them with their post-release plans have varied based on local conditions. ICE headquarters and field office officials explained that, prior to October 2018, when the volume of family units arriving at the southwest border began to increase significantly, ICE officers sometimes coordinated post-release plans for family units that did not stay at a family residential center. However, officials stated ICE has not had the resources to help family units with post-release plans since that time and instead has generally relied on nongovernmental organizations for this assistance. When ICE releases family units from its custody to await immigration court proceedings, ICE officers generally enroll the family unit’s head-of- household in its Alternatives to Detention program. The program uses technology, such as ankle monitoring devices, to track the movement of the adult family unit members. ICE field office officials stated that the availability of ankle monitoring devices and the volume of family units arriving at the southwest border can impact whether or not ICE enrolls a family head-of-household in its Alternatives to Detention program. In addition to ankle monitoring devices, most family units are also released on orders that require heads-of-household to report telephonically or in- person to ICE officers once they reach their destination in the United States. ICE officials stated the level of continued supervision by ICE officers is at the discretion of the ICE officer in charge of the family unit’s case and may also be dependent on a variety of factors, such as whether the family unit entered the United States at or between ports of entry, whether the family unit received a positive credible fear determination, and the head-of-household’s prior criminal and immigration record. ICE relies on a manual process to track family unit separations that occur in ICE custody, but does not systematically record this information in its data system. ICE officers are to report all separations that occur in ICE custody to the headquarters office responsible for coordinating family and juvenile programs. ICE headquarters officials in that office compile the information received from the field offices to populate a spreadsheet, which they use to track all separations that occur in ICE custody. In addition, according to ICE officials at headquarters, officers are to include narrative information about the separation and the approving official’s name in a comments field in the parent’s and children’s records in the data system. According to ICE officials, the narrative information in the comment field is not searchable within ICE’s data system and ICE does not have a mechanism, such as a drop-down menu, to systematically record a family unit separation or the reasons for any separations that occur in ICE custody. Thus, ICE cannot pull data from its system to track such separations. ICE headquarters officials stated that these methods are not an efficient and effective means to have readily available data on family separations that occurred in ICE custody. According to ICE policy for detained parents, detained parents maintain their parental rights during removal proceedings. In particular, if ICE is removing a parent from the United States, field office directors or their designees are to accommodate, to the extent practicable, the detained parent’s efforts to make arrangements for his or her minor child or children, including for the children to be removed with the parent. As such, before removing an adult from the United States, ICE officers are to check the individual’s paper A-file, and specifically the individual’s Form I- 213, for any indication the adult arrived with a child, according to ICE headquarters officials. In addition, according to ICE officials, ICE officers are to review the individual’s record in ICE’s data system where ICE officers would be alerted to whether the individual had ever been separated from a child. Given the limitations in ICE’s data system, officers would need to know to review the narrative information in the comments field within the individual’s records to determine whether he or she had been separated from a child in ICE custody; however, none of ICE’s guidance documents explain that officers are to look for such information in the narrative comments field. Further, ICE officials told us that officers are not required to check the spreadsheet maintained at ICE headquarters or contact headquarters officials prior to removing adults from the United States. As of November 2019, ICE headquarters officials stated they are working with the ICE data unit to create a new module that would enhance ICE’s ability to link and track family units in its data system, including capturing information on families that ICE separates. According to ICE officials, ICE has established a project team for this effort and hopes to deploy the updates in the fourth quarter of fiscal year 2020. However, ICE did not provide documentation with details, such as a project plan with time frames for deploying these system updates, to verify these plans. Standards for Internal Control in the Federal Government states that management designs the entity’s information system and related control activities to achieve objectives and respond to risks. Further, management designs the entity’s information system and the use of information technology by considering the defined information requirements for each of the entity’s operational processes. Given that ICE did not provide documentation with details about planned changes to ICE’s data system, it is too early to determine whether and when ICE’s planned system enhancements will include a mechanism that allows ICE officers to systematically track family separations that occur in ICE custody. Without a mechanism in its data system to systematically track the family units it separates, ICE is unable to ensure that separated parents who are subject to removal are able to make arrangements for their minor child or children (including being removed with them), as provided in ICE policy . DHS and HHS have developed interagency agreements for the transfer and placement of UAC between the two departments; however, information sharing gaps remain. In 2015, we reported that the interagency process to refer UAC from DHS to HHS was inefficient and vulnerable to errors because it relied on emails and manual data entry. In addition, each DHS component (Border Patrol, OFO, and ICE) submitted referrals for UAC to HHS’s ORR in a different way. To increase the efficiency and improve the accuracy of the interagency referral and placement process for UAC, we recommended the Secretaries of Homeland Security and Health and Human Services jointly develop and implement a documented interagency process with clearly defined roles and responsibilities for all agencies involved in the referral and placement of UAC in HHS shelters. DHS and HHS concurred with our recommendation. Since our 2015 report, DHS and HHS developed two documents to guide interagency procedures related to the processing of UAC. Specifically, in April 2018, HHS and DHS established a memorandum of agreement regarding information sharing for UAC. In addition, on July 31, 2018, DHS and HHS issued a Joint Concept of Operations to memorialize interagency policies, procedures, and guidelines related to the processing of UAC. According to the April 2018 memorandum of agreement, among other things ICE and CBP are to provide ORR with information at the time of the referral and documents when the child is transferred to ORR, including whether the child was traveling with other individuals and the Form I-213, so that ORR can make informed decisions for the child. Specifically, once a child has been transferred to ORR, the agency begins the process of identifying a potential sponsor for the child and, when a potential sponsor is identified, ORR requests information about that sponsor. At this step, according to the memorandum of agreement, ICE is to conduct a screening of the potential sponsor that includes, at a minimum, a biographic criminal check of national databases, a check for warrants of arrest, and an immigration status check. DHS is to provide HHS with information necessary to conduct suitability assessments for sponsors, including that which HHS would not otherwise have access. In addition, to the extent permitted by law, and consistent with policy, DHS is to report to ORR the results of any investigations it conducts that are relevant to ORR’s determinations concerning the care and placement of UAC. According to the July 2018 Joint Concept of Operations, ICE or CBP should use ORR’s data system to refer UAC to ORR whenever feasible. If ORR’s data system is not available, DHS may email ORR a referral form along with any supporting documentation. DHS is also to provide ORR with specific documents, including the Form I-213, when the child is transferred to ORR. In the event a child is separated from a parent or legal guardian, CBP or ICE is to enter this information into ORR’s data system, according to the Joint Concept of Operations. CBP or ICE is also to include contact information for parents, legal guardians, or adult relatives, as this information can assist in ORR’s reunification process, if needed. ORR is to contact the child’s family to, among other things, determine whether the child has a potential sponsor who resides in the United States, and to facilitate visitation and contact with family members, regardless of their immigration status. Finally, DHS is to preserve the unity of families during repatriation, according to the Joint Concept of Operations. The memorandum of agreement and Joint Concept of Operations state the roles and responsibilities of DHS and HHS and their components and describe some of the information to be shared between the agencies regarding the placement of UAC, among other things. However, DHS and HHS officials’ statements indicate that, in practice, they have not resolved long-standing differences in opinion about whether and how agencies are to share information, and what type of information is needed to inform decisions about the care and placement of UAC, including those processed as UAC after separation from a parent. We found that DHS has not consistently provided information and documents to ORR as specified in the memorandum of understanding and the Joint Concept of Operations. Further, ORR officials identified additional information they believe ORR needs from DHS at the time of referral (or soon thereafter) to inform their decisions about placing children with sponsors and reunifying separated families, when necessary. With regard to information sharing expectations established in the interagency agreements, as of September 2019, we found that certain documents were not being shared or mechanisms for sharing information were not being used consistently. For example, Border Patrol has taken steps since our 2015 report to improve its referral process, so that Border Patrol’s referral information is uploaded directly into ORR’s data system, in keeping with Joint Concept of Operations requirements. However, the referral screens in Border Patrol and ORR data systems do not fully align, which has required ORR headquarters staff to manually enter some required information into the ORR data system. That is, Border Patrol’s referral screen does not include many of the fields—areas to input specific information—included in ORR’s referral screen. Border Patrol and ORR officials offered different perspectives on why the information on the referral screens in the data systems do not align. Specifically, ORR officials stated that Border Patrol has not updated its referral screen to match updates that ORR has made. For example, in July 2018, ORR added a checkbox in its data system for DHS agencies to indicate whether a UAC had been separated from a parent, as necessary. Border Patrol took steps in October 2018 to similarly update its referral screen, so the indication of a family separation would be automatically uploaded to ORR’s data system with the referral. However, additional steps must be taken by ORR for its data system to upload the information, according to Border Patrol officials. Meanwhile, if ORR staff see some indication of a family separation in the Border Patrol referral form, such as in a narrative text field, ORR staff will typically add that information to the records in their data system manually. Border Patrol has not taken additional steps to update other parts of its system’s referral screen to align with ORR’s data system because ORR’s data system does not comply with DHS security standards, according to Border Patrol officials. ORR officials said they had not been made aware of any security concerns. However, concern about system security standards is a long-standing issue that we noted in our 2015 report. As of October 2019, Border Patrol and ORR did not have any plans to collaborate further to improve automated referrals for UAC. Further, as of October 2019, ORR officials told us that ICE and OFO officials are not consistently accessing the ORR data system to submit a referral for a UAC. Specifically, ICE and OFO officers in certain locations use ORR’s data system to submit a referral infrequently and instead use a form, which ORR last updated in 2013, that they attach to emails to refer UAC. However, ORR officials stated their expectation is that email referrals are to be used only occasionally, such as if DHS officials encounter technical problems using ORR’s data system. ICE and OFO stated that their officers only rarely make referrals to ORR and sometimes face constraints that prohibit them from using ORR’s data system to submit the referral. For example, ICE officials stated that officers generally use ORR’s data system for referrals, but that, on some occasions, the officer’s password to access ORR’s data system has expired due to infrequent use, and they must email the referral. In addition, OFO and ICE officials stated that their officers who have access to the ORR data system to make referrals are not always available, so in those instances, other officers must email a referral form to ORR. OFO and ICE headquarters officials were unsure how often their officers used email to send ORR referrals, rather than directly accessing ORR’s data system. ORR officials also stated that even when ICE and OFO use ORR’s data system to submit the referral, consistent with the Joint Concept of Operations, the officers are not consistently marking the separations checkbox in ORR’s data system for those children involved in family separations. As a result of these challenges, ORR officials said they must often manually enter referral information from ICE or OFO into the ORR data system, including any indication of a family separation or that the child was apprehended with an adult. ORR officials also stated that DHS—CBP and ICE—is not routinely submitting the child’s Form I-213 to ORR, as specified by both interagency agreements. Border Patrol and OFO headquarters officials stated they have concerns about sharing sensitive information, including in referral forms or on the Form I-213, with ORR headquarters or contracted shelter staff because they are not law enforcement officers. ORR headquarters officials stated that they have worked with other federal partners to ensure that only ORR officials with the proper authorization receive sensitive materials. These officials said they are interested in working with DHS to set up a similar process so ORR can receive the information it needs to make decisions for UAC. For example, ORR headquarters officials stated that they would explore options for updating DHS and HHS data systems so the child’s Form I-213 could be shared directly between data systems. This would help ensure that only ORR staff who have the proper authorization will have access to them, according to HHS officials. In addition, DHS and HHS provided different perspectives on the expected information sharing procedures included in the interagency agreements. For example, ORR headquarters officials stated they interpret existing interagency agreements to apply to information sharing on all UAC, regardless of whether they were apprehended alone or with an adult. By contrast, Border Patrol headquarters officials stated that the interagency agreements apply to UAC involved in family separations, but not those children referred to ORR after Border Patrol assessed a family relationship to be invalid. In addition, ICE headquarters officials stated that the interagency agreements were drafted to reflect the circumstances of children apprehended alone, not separated children or those CBP assesses to have invalid family relationships. ICE officials also stated they no longer believe the April 2018 memorandum of agreement is valid for any UAC, because it was developed to address a process ORR no longer requires. ORR identified additional information sharing needs—some not covered by existing interagency agreements—to inform decisions regarding the care and placement of UAC. Specifically, this information includes details about the circumstances of family separations, and information about adults who were apprehended with children (who subsequently were designated as UAC). ORR officials stated that ORR and ICE require this information, collected by DHS, to (1) assess potential sponsors for placement of UAC and (2) to reunify eligible separated families. Assessing Potential Sponsors. ORR officials stated that ORR needs additional information about parents and other adults accompanying a child (who is later designated as a UAC) at the time of apprehension to assess all potential sponsors with whom UAC will be placed as they await immigration proceedings in the United States. However, the Joint Concept of Operations contains limited details about what information should be shared between DHS and HHS about relevant adults. For example, the agreement states that ICE and CBP will provide ORR with contact information for parents, legal guardians, or adult relatives. However, the agreement does not, for example, require DHS to share the details of an adult’s criminal history information to ORR. In addition, Border Patrol headquarters officials stated that agents typically would not alert ORR to any concerns about invalid family relationships, as they do not believe that information is relevant. ORR officials stated they need detailed information about an accompanying adult to assess whether they could potentially pose a danger to the child, and this is not addressed in the Joint Concept of Operations. However, ORR officials stated that this information is often not included in DHS’s referrals for UAC, and ORR sometimes learns about an accompanying adult from a child after placement in an ORR shelter. Reunifying Eligible Separated Family Units. To ensure compliance with the federal court injunction in the Ms. L. v. ICE litigation, ORR officials stated that they need to know enough details about (1) family separations or (2) situations in which CBP had concerns a family relationship was invalid, to determine whether there are any family units potentially eligible for reunification. If DHS and HHS determine that a parent will be reunified with a child, ORR is responsible for (1) verifying the validity of the family relationship and (2) determining whether the parent is fit or poses a danger to the child, according to ORR officials. For family unit reunifications, ORR has relied, in part, on the determinations made by DHS when the family was separated, according to these officials. However, ORR officials stated the information DHS provides about family separations is generally limited or provided inconsistently, often without enough detail for ORR to assess whether the family unit may be eligible for reunification. For example, the referral might state a family separation is due to the parent’s criminal history, but ORR must follow up with ICE to specify the charge, determine whether the adult was convicted, or learn the date of the event. In addition, ORR may conduct family reunifications in accordance with ORR policies and procedures in other situations. For example, there have been cases in which families were separated, but DHS later dropped criminal charges against a parent it planned to prosecute, or a parent has completed a hospitalization that required the parent to be separated from his or her child. According to ICE policy, when ICE is removing a parent from the United States, that parent has the right to determine whether a minor child will be removed with him or her. ORR officials stated that, according to ORR policies and procedures, if the child is to be removed with the parent, ORR must assess whether (1) the family relationship is valid and (2) whether the parent presents a danger to the child. However, ORR officials stated that if this information was not provided at the time of referral, they must reach out to ICE officials to collect it. Further, ORR headquarters officials stated that ICE has removed adults from the United States who wished to be removed with their child or children in ORR custody, before ORR could complete its assessment. However, neither ICE nor ORR could determine exactly how often that had occurred or in exactly what time frame these removals had occurred. DHS and HHS officials provided different perspectives on these information sharing challenges not covered within existing interagency agreements. ORR takes additional steps to collect information from ICE and CBP that ORR is not routinely receiving at the time of referral. This can extend the time that children spend in ORR custody, according to ORR officials. If ORR staff conducting intake duties have questions about UAC and any accompanying adults, ORR headquarters officials told us they typically first contact the local CBP officials who processed the apprehension. In April and August 2019, ORR officials said that some Border Patrol sectors are more responsive than others and that limited and inconsistent information sharing by DHS about separated children has led to delays in placement and release decisions for UAC. ORR staff also reach out to ICE’s field office juvenile coordinators or ICE headquarters officials responsible for juvenile and family management. For example, ORR and ICE headquarters coordinate on a weekly basis via email to assess whether family separations are in compliance with federal court orders in the ongoing Ms. L. v. ICE litigation. Specifically, since February 2019, ORR and ICE have shared a spreadsheet tracking UAC who may have been involved in a family separation, according to ORR and ICE headquarters officials. Further, ICE officials said they gather additional information, such as more details about the reason for a family separation from the Form I-213 or by reaching out to CBP officials. They provide some of this information to ORR, as ICE officials noted that they recognize ORR needs such information to assist in its decision-making for UAC. ICE headquarters officials noted that they have found ways to provide more detailed information to ORR without sharing sensitive law enforcement information. It is through this vetting process that ICE and ORR assess potential family separations to reach a confirmed number of cases and the reasons for them, according to ICE and ORR officials. ORR headquarters officials stated that, from their perspective, it would be more efficient if CBP or ICE provided this information directly into ORR’s data system at the time of referral, where possible, rather than sharing a spreadsheet via email. Specifically, ORR headquarters officials stated that they have experienced delays in releasing a child to a sponsor due to missing information about a parent or the inability to notify a parent in ICE detention about sponsorship decisions. By contrast, Border Patrol and OFO headquarters officials noted concerns about sharing sensitive information with ORR, particularly for adults apprehended with UAC. Border Patrol officials stated, for example, that Border Patrol does not share sensitive law enforcement information with a third party such as ORR. According to ICE headquarters officials, sometimes ICE officers conduct additional research after a child is referred to ORR, such as if CBP was unable to collect certain information before making a separation decision. ICE officials stated that, for their purposes, the current information sharing procedures in place are sufficient, but noted that ICE has added staff resources to keep up with the demands of current information sharing procedures. Specifically, until May 2019, there was one ICE headquarters official, 2in the juvenile and family management unit, responding to all of ORR’s requests, and that ICE added another staff person to assist in responding to ORR’s requests. As of October 2019, there were no plans to discuss further these information sharing concerns, according to ORR, CBP, and ICE officials. Leading practices of high-performing organizations include fostering collaboration both within and across organizational boundaries to achieve results. Further, agencies should work together to establish a shared purpose and goals; develop joint strategies or approaches that complement one another; and ensure the compatibility of policies, procedures, and other means to operate across agency boundaries. We have previously reported that written agreements, such as a memorandum of understanding or interagency agreements, can help facilitate collaboration by articulating roles and responsibilities, among other things. These types of written agreements are most effective when they are regularly updated and monitored, as we reported in 2012. While issuing the April 2018 memorandum of agreement and July 2018 Joint Concept of Operations were important steps toward addressing the weaknesses we identified in our 2015 report, additional actions are needed to fully address our recommendation and increase the efficiency and improve the accuracy of the interagency referral and placement process for all UAC. In addition, further DHS and HHS collaboration about information sharing methods and ways to enhance interagency agreements would better position ORR to make informed and timely decisions for UAC, including those separated from adults with whom they were apprehended. As the number of CBP apprehensions of family units has risen markedly in recent years, DHS has developed policies and procedures for processing family units. For example, since 2015 CBP has introduced policies and procedures for collecting information about family units, which has increased the data it collects, including on family separations. However, DHS continues to face challenges in ensuring that it accurately and consistently tracks information about family units, including those it separates. Specifically, CBP training includes definitions of and guidance for processing family units that are inconsistent with CBP policy. Issuing updated training materials with correct definitions of and guidance for processing family units would help CBP ensure that its agents and officers are accurately tracking family units and, where applicable, family separations. In addition, CBP has policies and procedures related to concerns about the validity of a family unit, but it does not have written requirements about what information on these cases Border Patrol agents and OFO officers are to record. Without additional guidance about what details CBP agents and officers are to record on the required Form I-213, these cases will not be well documented, as required by CBP policy. Further, ICE and ORR officials do not have sufficient information to make decisions for the adults and children involved, including determining when reuniting valid family units is necessary. CBP has developed policies and procedures related to family separations, but additional controls would help Border Patrol and OFO ensure that information about these cases is accurately and consistently captured. By developing and implementing additional controls for tracking family separations—such as requiring checks during supervisory review that separations were documented properly—Border Patrol could better ensure it has accurate information about these cases, consistent with CBP and Border Patrol policies. Further, some of the options for separation reasons in Border Patrol’s and OFO’s data systems do not fully align with CBP policy. Without updating the reasons agents and officers have available to select from, CBP is not well positioned to determine whether its officials are separating family units for reasons consistent with CBP policy. In addition, during our review of selected Forms I-213 for a sample of separated family units, we found that agents did not always include the reason for the separation or include a detailed description of the circumstances of the case. Developing and implementing additional controls to check that Border Patrol agents document family separations and why they occurred on family unit members’ Forms I-213 could help Border Patrol ensure its agents are separating family units in accordance with CBP policy. Additionally, without additional guidance on what specific information about the circumstances of the family separations Border Patrol agents and OFO officers are to include on the parent’s and child’s Forms I-213, ICE and ORR do not have sufficient information to determine, among other things, when family reunifications are required. During our review of ICE’s policies and procedures for processing family units, we found that it does not systematically track the family units it separates in its data system. By updating its data system to do so, ICE would be better able to ensure that separated parents, who are subject to removal, are able to make arrangements for their minor child or children, including being removed with them, consistent with ICE policy. While DHS and HHS have developed written interagency agreements related to the transfer and care of UAC, as we recommended in 2015, we found that information sharing gaps between the two agencies remain. As such, continuing their efforts to address our prior recommendation to jointly develop and implement a documented interagency process for all agencies involved in the referral and placement of UAC could help DHS and HHS increase the efficiency and improve the accuracy of these processes for UAC. Moreover, additional DHS and HHS collaboration about information sharing would help provide ORR with additional information, including about accompanying adults, to make informed and timely decisions for UAC. We are making a total of nine recommendations, including six to CBP and one each to ICE, DHS, and HHS. Specifically: The CBP Commissioner should issue updated Border Patrol and OFO training materials that reflect the correct definition of a family unit and guidance for recording that information. (Recommendation 1) The CBP Commissioner should provide written guidance to Border Patrol agents and OFO officers about what narrative information should be recorded on the child’s and the accompanying adult’s Forms I-213 to document cases in which CBP determines that a parent–child relationship may be invalid. (Recommendation 2) The CBP Commissioner should develop and implement additional controls to ensure that Border Patrol agents accurately record family unit separations in its data system. (Recommendation 3) The CBP Commissioner should update Border Patrol’s and OFO’s data systems to ensure data captured on family unit separation reasons clearly align with CBP policy. (Recommendation 4) The CBP Commissioner should develop and implement additional controls to ensure that Border Patrol agents include a narrative description of a family unit separation on the parent’s / legal guardian’s and child’s Forms I-213, including the reason for the separation. (Recommendation 5) The CBP Commissioner should provide guidance to Border Patrol agents and OFO officers on the narrative information they are to include about family unit separation events on the parent’s / legal guardian’s and child’s Forms I-213. (Recommendation 6) The ICE Director should develop and implement a mechanism to systematically track in its data system the family units ICE separates. (Recommendation 7) The Secretary of Homeland Security, jointly with the Secretary of Health and Human Services, should collaborate to address information sharing gaps identified in this report to ensure that ORR receives information needed to make decisions for UAC, including those apprehended with an adult. (Recommendation 8) The Secretary of Health and Human Services, jointly with the Secretary of Homeland Security, should collaborate to address information sharing gaps identified in this report to ensure that ORR receives information needed to make decisions for UAC, including those apprehended with an adult. (Recommendation 9) We provided a draft of this report to DHS and HHS for review and comment. DHS and HHS provided formal, written comments, which are reproduced in full in appendixes III and IV, respectively. DHS and HHS also provided technical comments on our draft report, which we incorporated, as appropriate. DHS concurred with our recommendations and described actions planned or underway to address them. For example, in response to several of our recommendations that CBP provide additional or revised guidance and training to agents and officers, DHS stated that Border Patrol issued a memo in January 2020 to clarify what information agents are to record for family unit members, potentially invalid family units, and subsequent separations, if applicable. DHS also described planned updates to OFO data systems to automatically record certain information in family unit members’ Form I-213, such as the names and identifying information of all family members apprehended together. Regarding our recommendation that CBP should update Border Patrol’s and OFO’s data systems to ensure the options for family separation reasons clearly align with CBP policy, DHS provided documentation of guidance that OFO and Border Patrol issued about data system updates. DHS requested that we consider the recommendation implemented. We will review the information and documents DHS provided to assess the extent to which CBP fully addressed this recommendation. Regarding our recommendation that ICE develop and implement a mechanism to track its separations in its data system, DHS stated that ICE has efforts underway to enable ICE officers to track separations and reunifications in its data system throughout ICE’s immigration enforcement process. DHS and HHS also both concurred with our recommendations that the agencies collaborate to address information sharing gaps identified in this report, and described plans to coordinate and reach agreement on information sharing practices. We will review the agencies’ actions and planned efforts, including any documentation provided by DHS and HHS, and the extent to which they address each of our nine recommendations. As agreed with your offices, unless you publicly announce the contents of this report earlier, we plan no further distribution until 30 days from its issue date. At that time, we will send copies of this report to the appropriate congressional committees, the Acting Secretary of Homeland Security, and the Secretary of Health and Human Services. In addition, the report is available at no charge on the GAO website at https://gao.gov. If you or your staff have any questions about this report, please contact me at (202) 512-8777 or gamblerr@gao.gov. Key contributors to this report are listed in appendix V. The objectives of this report were to examine (1) what U.S. Customs and Border Protection (CBP) data indicate about the numbers and characteristics of family units who have been apprehended along the southwest border, (2) the extent to which CBP has developed and implemented policies and procedures for processing family units apprehended along the southwest border, (3) the extent to which U.S. Immigration and Customs Enforcement (ICE) has developed and implemented policies and procedures for processing family units apprehended along the southwest border, and (4) how the Department of Homeland Security (DHS) shares information with the Department of Health and Human Services (HHS) about unaccompanied alien children (UAC), including those children who initially arrived with and were separated from their parents or other adults. To address these objectives and to observe agents and officers processing families, we conducted site visits at U.S. Border Patrol stations and Office of Field Operations (OFO) ports of entry in Arizona, California, and Texas, from July 2018 to October 2018. We also visited ICE family detention facilities, known as family residential centers, in Dilley and Karnes City, Texas in February 2019. Specifically, in Tucson, Arizona we visited Border Patrol’s Tucson sector headquarters and OFO’s Tucson Field Office headquarters and the Nogales port of entry. In the San Diego, California region, we visited Border Patrol’s San Diego sector headquarters and Imperial Beach station and the San Ysidro port of entry. In the Rio Grande Valley, Texas region, we visited CBP’s Central Processing Center, Border Patrol’s McAllen station, and the Hidalgo and Brownsville ports of entry. In the San Antonio, Texas region, we visited ICE’s San Antonio field office headquarters, South Texas Family Residential Center, and Karnes County Residential Center. During these site visits, we interviewed Border Patrol, OFO, and ICE officials, observed agents and officers processing families, and toured CBP and ICE facilities, among other activities. To select these locations, we reviewed CBP data on Border Patrol and OFO apprehensions along the southwest border, including family unit apprehensions, and identified specific locations that had the greatest increase in the number of apprehensions of individuals from fiscal year 2016 to 2017. We also considered the geographical proximity of multiple CBP and ICE facilities to maximize observations. Our observations during site visits are not generalizable to all Border Patrol, OFO, and ICE operations along the southwest border, but provided us the opportunity to learn more about how policies and procedures for processing families are conducted and how CBP and ICE coordinate their efforts. In addition, to address all of our objectives, we interviewed DHS and HHS officials. Specifically, we met with DHS officials from CBP’s Office of the Commissioner and Office of Chief Counsel; Border Patrol’s Law Enforcement Operations Directorate and Strategic Planning and Analysis Directorate; OFO’s Admissibility and Passenger Programs office; ICE’s Enforcement and Removal Operations (including the Juvenile Family and Residential Management Unit, Field Operations, Alternatives to Detention, and Law Enforcement Systems and Analysis) and ICE’s Office of the Principal Legal Advisor. We also interviewed HHS officials from the offices of the Assistant Secretary for Preparedness and Response and Office of Refugee Resettlement (ORR). To address our first objective and describe what CBP data indicate about the numbers and characteristics of family units who have been apprehended along the southwest border, we reviewed record-level apprehensions data from CBP’s Border Patrol and OFO for individuals determined to be inadmissible or potentially subject to removal. We collected data for fiscal year 2016 through the second quarter of fiscal year 2019 because Border Patrol and OFO began to systematically collect data on individuals apprehended as part of a family unit in fiscal year 2016. The second quarter of fiscal year 2019 was the most current data available at the time of our review. We used “number of apprehensions” rather than the “number of individuals or family unit members” as the unit of analysis we reported because an individual may have been apprehended multiple times in the same year. The data we report on apprehensions of family unit members include individuals in family units CBP later separated (for reasons other than concerns about validity of the family relationship) from April 19, 2018, when Border Patrol and OFO began collecting data on family separations, through the first two quarters of fiscal year 2019. The record-level data we analyzed are current as of the date Border Patrol or OFO provided it to us. Specifically, Border Patrol data for fiscal years 2016 through 2018 are current as of January 2019; Border Patrol data for the first two quarters of fiscal year 2019 and selected fields for all fiscal years are current as of April 2019. OFO data for fiscal years 2016 through 2018 are current as of February 2019; OFO data for the first two quarters of fiscal year 2019 are current as of June 2019. We grouped the ages of apprehended children in family units (e.g. ages 0–4, 5–11, and 12–17) according to key agency and court documents. While most of our analysis was conducted on the apprehensions of individuals in family units, we were also able to analyze the composition of family units (i.e., as a group rather than individuals) apprehended by Border Patrol. Specifically, Border Patrol uses a “family unit number” to link the records of adult(s) and children processed as a family unit. As a result, we analyzed whether the family unit was headed by an adult male or adult female and how many children were in the family unit. We could not conduct a similar analysis for the family units apprehended by OFO, because OFO does not assign family units unique identifying numbers to link family members in its data system. As a result, we were unable to report on the composition of family units that OFO encountered. As part of our analysis of CBP data, we determined the number of family unit members Border Patrol and OFO data indicated as separated from April 19, 2018 through March 31, 2019. We selected this time frame because Border Patrol began to systematically collect data on family separations in its data systems on April 19, 2018, and the second quarter of fiscal year 2019 was the most current data available at the time of our review. Our analysis of the reasons for family separations is based on the data recorded by agents and officers in Border Patrol’s and OFO’s data systems. During the period of our review, Border Patrol’s and OFO’s data systems included options for agents and officers to choose from to explain the reason for the separation, including, for example, “family member prosecuted – criminal history” and “family member prosecuted – other reasons.” These reasons, and the numbers of separations for each reason, reflect CBP data and may not match the information about separations (including numbers of, reasons for, and timeframes of separations) that DHS reported to a federal court in response to related litigation, such as Ms. L. v. ICE. According to court filings, the information provided in response to that litigation was based on a manual review of multiple federal datasets and reflect categories as required by the litigation. We excluded family separations indicated in CBP data as temporary from our analysis. We also reported separately on the number of adults and children who were apprehended together, but whom CBP assessed to have potentially invalid family relationships and thus processed separately, as CBP does not consider these family separations. To assess the reliability of CBP data, we completed a number of steps, including (1) performing electronic testing for obvious errors in accuracy and completeness, such as running logic tests; (2) reviewing existing information about the data and the systems that produced them, such as relevant training materials for Border Patrol agents and OFO officers who use agency data systems; and (3) discussing data entry issues and data limitations with Border Patrol and OFO officials. We also received demonstrations on the data systems from Border Patrol and OFO officials at headquarters. The limitations and determinations of reliability for the Border Patrol and OFO data are discussed in more detail below. Border Patrol data. We identified a small number of Border Patrol apprehension records that had the same date of apprehension and unique identifier, known as the “A-number.” It is possible that these apprehension records represented one apprehended individual that Border Patrol agents processed as two apprehensions. These records constituted less than 1 percent of the almost 2.4 million apprehension records we analyzed. We included these apprehension records in our analysis because Border Patrol considers them unique apprehensions and because their small number does not materially affect our analysis. We did not include a small number of records (less than 1 percent of apprehensions of family unit members) that had a family unit number but did not meet CBP’s definition of a family unit in our analysis of records of family unit members. For example, a small number of family unit member records did not include a date of birth, so we could not determine whether the individual was an adult or child (i.e., under or over the age of 18 years). For our analysis of the reasons for family separations, we found a small number (18) of Border Patrol records that included more than one separation reason, so we could not distinguish which reason led to a permanent family separation. Thus, we excluded these records from our analysis of the reasons for family separations. According to Border Patrol headquarters officials and documents, in situations in which only one of the adults in a two-parent family was separated, the child or children would remain with the other adult as an intact family unit (and the child would not be designated a UAC and transferred to the custody of ORR). As such, in these situations, we included the separated adults in our reported numbers of separated family unit members, but did not include associated remaining family units in our analysis of separated family units. We found 18 records for family units that included one adult and one child, with one of the family unit members separated. According to Border Patrol’s procedures, in the event a family separation occurs, both family unit members are to be processed in the data system as “separated.” We included these records in the number of family unit members, but did not include them in our analysis of separated family unit members, as it was unclear from the records whether or not the family unit was separated. We identified data reliability issues with Border Patrol’s data on family separations, as described in our report. When reporting these data, we rounded down to the nearest increment of five, and described relevant data using modifiers such as “at least” because of possible missing information. This enabled us to report on the Border Patrol data that we determined were sufficiently reliable for our purposes. OFO data. For the OFO data, we excluded approximately 11 percent of all apprehension records (including single adults, UAC, and parents and children that arrived as part of a family unit) from our analyses because we could not confirm an A-number, for those apprehensions. Among the apprehension records missing an A-number, 44 percent were cases in which OFO officers paroled the individuals and, according to OFO officials, officers are not required to assign an A-number to these individuals. In addition, 47 percent of the records with a missing A- number were cases that involved individuals withdrawing their applications for admission into the United States, in which OFO officers have discretion whether or not to assign an A-number. According to OFO officials, additional records with missing A-numbers may be due to human error during data entry or problems with the data system saving this information in the database that OFO used to pull the data. Finally, we collapsed 153,025 apprehension records into 71,986 apprehension records because we determined that they were duplicate records for the same individual and the same apprehension, based on factors such as A- number, birth date, and date and time of apprehension. As a result, we determined that we could not present precise figures for analyses that include OFO data and instead provided approximations throughout the report. We rounded all data and figures on OFO apprehensions, including where OFO’s data inform CBP-data and figures, down to the hundreds place. As an exception, for the much-smaller number of OFO family separations, as compared with total apprehensions, we rounded the figures by increments of five, and described relevant data using modifiers such as “at least” because of possible missing information. This enabled us to report on the OFO data that we determined were sufficiently reliable for our purposes. With the previously described modifications, we determined that the Border Patrol and OFO data were sufficiently reliable to generally describe the number and demographic characteristics of family units apprehended by CBP along the southwest border. To address the second objective, on the extent to which CBP has developed and implemented policies and procedures for processing family units—including how CBP defines family units, assesses the validity of family relationships, and determines whether family separations are warranted—we reviewed CBP, Border Patrol, and OFO policy documents, training materials, and other guidance documents in effect from October 2015 through December 2019. For example, we reviewed CBP’s 2015 National Standards on Transport, Escort, Detention, and Search policy, as well as Border Patrol’s data system processing guidance and Border Patrol and OFO policies and procedures on how agents are to record family separations in agency data systems, among other documents. We compared CBP, Border Patrol and OFO policies and procedures to Standards for Internal Control in the Federal Government related to identifying, analyzing, and responding to change; designing control activities to achieve objectives and identify risks; and using quality information to achieve objectives. We also compared Border Patrol definitions for family units, and processes and guidance for tracking family units, invalid family units, and family unit separations against CBP and Border Patrol policy. To evaluate how Border Patrol recorded information for family units apprehended from June 28, 2018 through March 31, 2019, we also selected a sample of ORR records for UAC involved in family separations and compared them to Border Patrol apprehensions data for the same children. Specifically, we selected a small, random, nongeneralizable sample of 40 ORR records for UAC involved in family separations. We then matched all 40 selected records to Border Patrol apprehensions data, using unique identifiers. Our findings are not generalizable due to the size of our sample, so we cannot use our findings to assess the magnitude of the issues we identified in Border Patrol data. We limited the records from which we selected our sample to those ORR records that included an A-number, a unique identifier, for the adult separated from the child in ORR custody, since Border Patrol tracks its separation reasons in the adult’s records. Finally, we compared this information with CBP’s October 2015 National Standards on Transport, Escort, Detention, and Search policy, which states that family separations must be documented in the appropriate data systems. We also assessed information against federal internal control standards, which call for management to identify and use quality information to achieve the entity’s objectives and address risks, among other control activities. To describe how Border Patrol agents document the reasons for and circumstances of each family separation case, we reviewed a nongeneralizable sample of the DHS Form I-213, Record of Deportable/Inadmissible Alien (Form I-213), which is a form that agents are required to complete for each individual CBP apprehends. Specifically, Border Patrol provided us with Forms I-213 for the adults and children involved in the three most recent instances of family separation from June 28, 2018 through March 30, 2019, in each of Border Patrol’s nine sectors along the southwest border. Two of the sectors only had one family separation during that period, so we reviewed the forms for a total of 23 family separations. We reviewed a sample of Forms I-213 prepared by Border Patrol agents, as Border Patrol separated approximately 95 percent of the family separations indicated in CBP data during the period we reviewed. We did not review a sample of Forms I-213 prepared by OFO officers, given the relatively smaller number of families separated by OFO. In addition, we reviewed a sample of forms for cases of family separations only, and did not review forms for cases in which Border Patrol determined the family relationship was invalid because Border Patrol officials told us that they do not record information about assessments of invalid family relationships on the Form I-213. Finally, we compared this information with a 2015 CBP policy that states that family separations must be documented in the appropriate data systems; a June 2018 CBP policy that includes potential reasons to warrant family separations; and federal internal control standards, which call for management to identify and use quality information to achieve the entity’s objectives and address risks, among other control activities. To address the third objective, and examine the extent to which ICE has developed and implemented policies and procedures for processing families apprehended along the southwest border, we reviewed ICE policy documents, training materials, and other guidance documents. For example, we reviewed ICE’s Juvenile and Family Residential Management Unit Field Office Juvenile Coordinator Handbook, ICE’s Family Residential Standards, ICE’s data system training manual, and ICE’s detained parent policy. We compared ICE’s processes against ICE policies and procedures and federal internal control standards, which call for management to design the entity’s information system and related control activities to achieve objectives and respond to risks. ICE data. To report on family members apprehended by CBP and detained in ICE family residential centers, we reviewed ICE detention data from June 2014, when ICE opened its first family residential center on the southwest border, through fiscal year 2018, the most current data available at the time of our review. The data for all fiscal years is current as of May 2019, when ICE provided us with record-level data to analyze. To assess the reliability of ICE’s data, we completed a number of data reliability steps, including (1) performing electronic testing for obvious errors in accuracy and completeness, such as running logic tests; (2) reviewing existing information about the data and the systems that produced them, such as relevant training materials for the ICE officers who use them; and (3) discussing data entry issues and data limitations with ICE officials. We also received demonstrations on ICE’s data system from officials at headquarters. We determined that the data were sufficiently reliable to describe the numbers and demographic characteristics of family members who were apprehended by CBP and detained by ICE at one of its family detention facilities. Additionally, we collected and reviewed data on the families whom ICE separated from July 2018 through September 2019. We selected this time frame because July 2018 is when ICE began to require its field offices to report all instance of family separations to headquarters, which tracks the information on a spreadsheet, and September 30, 2019, the end of the fiscal year. We reported the total number of family separations from the spreadsheet, but could not independently verify the number of separations in ICE’s spreadsheet because ICE does not track family separations systematically in its data system. As a result, we reported the total number of family separations, according to ICE, for context to demonstrate that most family separations occur when family units are in CBP custody. To describe how DHS shares information with HHS about UAC, including those involved in family separations, we reviewed DHS and HHS interagency agreements, including the April 2018 information sharing memorandum of agreement and July 2018 Joint Concept of Operations. Additionally, we interviewed DHS and HHS officials at headquarters and DHS officials at locations along the southwest border. We compared the information we gathered with DHS and HHS interagency agreements, which provide expectations for interagency information sharing and procedures for the care and custody of UAC. We also compared DHS and HHS information sharing practices to leading practices for collaboration among federal agencies. We conducted this performance audit from July 2018 to February 2020 in accordance with generally accepted government auditing standards. Those standards require that we plan and perform the audit to obtain sufficient, appropriate evidence to provide a reasonable basis for our findings and conclusions based on our audit objectives. We believe that the evidence obtained provides a reasonable basis for our findings and conclusions based on our audit objectives. This appendix provides additional information about apprehensions of noncitizen family units by CBP’s U.S. Border Patrol and Office of Field Operations (OFO) at or between U.S. ports of entry from fiscal year 2016 through the second quarter of fiscal year 2019. It also provides additional information about family unit members who were apprehended by CBP and subsequently detained by U.S. Immigration and Customs Enforcement (ICE) at a family residential center at some point from fiscal year 2015 through fiscal year 2018. The following tables contain information on the demographics of CBP apprehensions of noncitizen family units and family unit members and the processing decisions that CBP agents and officers made for them. CBP data indicate that Border Patrol was responsible for the majority of the overall number of family unit member apprehensions by CBP from fiscal year 2016 through the second quarter of fiscal year 2019 (see table 9). CBP data indicate that family unit member apprehensions grew as a percentage of total CBP apprehensions from fiscal year 2016 through the second quarter of fiscal year 2019 (see table 10). For example, CBP data indicate that apprehensions of family unit members grew from about 22 percent of total southwest border apprehensions in fiscal year 2016 to about 51 percent of such apprehensions during the first two quarters of fiscal year 2019. CBP data indicate that most apprehensions of family unit members from fiscal year 2016 through the second quarter of fiscal year 2019 were nationals of Central American countries (see table 11). CBP data indicate that the majority of apprehensions of adult family unit members by CBP were females, while the majority of children were male (see table 12). Border Patrol’s data system collects information about the family units it apprehends. Border Patrol’s data indicate that family units that agents apprehended were generally headed by females, although the number of family units headed by males and two-parent family units increased from fiscal year 2016 through the first two quarters of fiscal year 2019 (see table 13). Border Patrol’s data indicate that most Border Patrol apprehensions of family unit members occurred in just three sectors (Rio Grande Valley, Texas; El Paso, Texas; and Yuma, Arizona) from fiscal year 2016 through the second quarter of fiscal year 2019 (see table 14). OFO data indicate that most OFO apprehensions of family unit members occurred in just four ports of entry (San Ysidro, California; El Paso, Texas; Hidalgo, Texas; and Nogales, Arizona) from fiscal year 2016 through the second quarter of fiscal year 2019 (see table 15). CBP data indicate that the majority of apprehensions of family unit members resulted in the family unit members being released into the interior of the United States with a notice to appear before an immigration court, which became increasingly common from fiscal year 2016 through the second quarter of fiscal year 2019 (see table 16). The following tables contain information on family units that CBP separated at the border. CBP data indicate that the majority of children that CBP separated from their parents from April 19, 2018 through March 31, 2019 were male (see table 17). CBP data indicate that CBP separated children that ranged in age from less than 1 year old to 17 years old from their parents from April 19, 2018 through March 31, 2019, and the majority of separated children were age 12 and over (see table 18). CBP data indicate that the majority of children that CBP separated from April 19, 2018, through March 31, 2019, were nationals from Central American countries and that more than half were Guatemalan nationals (see table 19). Border Patrol data indicate that the majority of family units that Border Patrol separated from April 19, 2018 through March 31, 2019 were headed by males who were apprehended with a single child (see table 20). Border Patrol data indicate that most adults that were separated from their children by Border Patrol from April 19, 2018, through March 31, 2019, had not been previously apprehended by CBP (see table 21). The following tables and figures contain information about the noncitizen family unit members apprehended by CBP and detained by ICE at ICE’s family residential centers from fiscal year 2015 through fiscal year 2018. ICE data indicate that from fiscal year 2015 through fiscal year 2018, ICE detained 139,098 family unit members at its family residential centers (see table 22). ICE data indicate that most child family unit members (ages 0 to 17) detained in ICE detention facilities were under the age of 13 (see table 23). ICE data indicate that the majority of adults detained at ICE’s family residential centers were female, and the gender of children detained was relatively equal between male and female (see fig. 7). ICE data indicate that the majority of family unit members detained at ICE’s family residential centers were from El Salvador, Guatemala, and Honduras, as well as Mexico (see fig. 8). ICE data indicate that the vast majority of family unit members who were detained in one of ICE’s family residential centers were subsequently released by ICE into the interior of the United States (see table 24).

Summary: In fiscal year 2019, CBP reported apprehending more than 527,000 noncitizen family unit members at or between U.S. ports of entry along the southwest border—a 227 percent increase over fiscal year 2018. In April 2018, the U.S. Attorney General issued a memo on criminal prosecutions of immigration offenses, which DHS officials said led to an increase in family separations. GAO was asked to review issues related to DHS's processing of family units. This report examines (1) CBP data on apprehended family unit members; the extent to which (2) CBP and (3) ICE developed and implemented policies and procedures for processing family units; and (4) how DHS and HHS share information about UAC. GAO analyzed record-level DHS and HHS data and documents; interviewed DHS and HHS officials; and visited DHS locations in California and Texas where CBP apprehensions of family units increased in 2017. Data from the Department of Homeland Security's (DHS) U.S. Customs and Border Protection (CBP) indicate that apprehensions of family unit members (noncitizen children under 18 and their parents or legal guardians) grew from about 22 percent of total southwest border apprehensions in fiscal year 2016 to about 51 percent of such apprehensions during the first two quarters of fiscal year 2019—the most current data available. During this period, CBP data indicated that most apprehensions of family units—about 76 percent—occurred between ports of entry by the U.S. Border Patrol (Border Patrol). With regard to family separations, from April 2018 through March 2019, CBP data indicate it separated at least 2,700 children from their parents, processing them as unaccompanied alien children (UAC) and transferring them to the Department of Health and Human Services (HHS). CBP developed some policies and procedures for processing family units but does not have sufficient controls to ensure effective implementation. For example, CBP policy requires that Border Patrol agents and officers track apprehended family unit members and, if applicable, subsequent family separations in agency data systems. GAO's analysis of Border Patrol documents and data indicates that its agents have not accurately and consistently recorded family units and separations. Specifically, GAO examined a nongeneralizable sample of 40 HHS records for children involved in family separations between June 2018 and March 2019 and matched them to Border Patrol apprehensions data for these children. GAO found Border Patrol did not initially record 14 of the 40 children as a member of a family unit (linked to a parent's record) per Border Patrol policy, and thus did not record their subsequent family separation. GAO found an additional 10 children among the 40 whose family separations were not documented in Border Patrol's data system as required by CBP policy during this period. Border Patrol officials were unsure of the extent of these problems, and stated that, among other things, data-entry errors may have arisen due to demands on agents as the number of family unit apprehensions increased. Thus, it is unclear the extent to which Border Patrol has accurate records of separated family unit members in its data system. Further, Border Patrol agents inconsistently recorded information about the reasons for and circumstances surrounding family separations on required forms. Developing and implementing additional controls would help Border Patrol maintain complete and accurate information on all family separations. DHS's U.S. Immigration and Customs Enforcement (ICE) is, among other things, responsible for detaining and removing those family units apprehended by CBP. ICE officers are to determine whether to accept or deny a referral of a family unit from CBP for detention in one of ICE's family residential centers, release family unit members into the interior of the United States, or remove family unit members (who are subject to final orders of removal) from the United States. ICE has procedures for processing and releasing family units from ICE custody. However, with regard to family unit separations, ICE relies on a manual process to track separations that occur in ICE custody (generally at one of ICE's family residential centers) and does not systematically record this information in its data system. Without a mechanism to do so, ICE does not have reasonable assurance that parents whom ICE separated from their children and are subject to removal are able to make arrangements for their children, including being removed with them, as provided in ICE's policy for detained parents. In 2018, DHS and HHS developed written interagency agreements regarding UAC. However, DHS and HHS officials stated they have not resolved long-standing differences in opinion about how and what information agencies are to share related to the care and placement of those children, including those referred to HHS after a family separation. GAO found that DHS has not consistently provided information and documents to HHS as specified in interagency agreements. HHS officials also identified additional information they need from DHS, about those adults apprehended with children and later separated, to inform their decisions about placing children with sponsors and reunifying separated families, when necessary. Increased collaboration between DHS and HHS about information sharing would better position HHS to make informed and timely decisions for UAC. GAO is making eight recommendations to DHS and one to HHS. Among them, CBP should develop and implement additional controls to ensure that Border Patrol agents accurately record family unit separations in data systems. GAO also recommends that ICE systematically track in its data system the family units ICE separates. Further, DHS and HHS should collaborate about information sharing for UAC. DHS and HHS concurred with the recommendations.
