Further Steps Are Needed to Mitigate Risks in the Visa Waiver Program

In May 2011, we reported that DHS implemented the Electronic System for Travel Authorization (ESTA) to meet a statutory requirement intended to enhance Visa Waiver Program security and took steps to minimize the burden on travelers to the United States added by the new requirement.However, DHS had not fully evaluated security risks related to the small percentage of Visa Waiver Program travelers without verified ESTA approval. DHS developed ESTA to collect passenger data and complete security checks on the data before passengers board a U.S. bound carrier. DHS requires applicants for Visa Waiver Program travel to submit biographical information and answers to eligibility questions through ESTA prior to travel. Travelers whose ESTA applications are denied must apply for a U.S. visa for travel to the United States. In developing and implementing ESTA, DHS took several steps to minimize the burden associated with ESTA use. For example, ESTA reduced the requirement that passengers provide biographical information to DHS officials from every trip to once every 2 years. In addition, because of ESTA, DHS informed passengers who do not qualify for Visa Waiver Program travel that they need to apply for a visa before they travel to the United States. Moreover, most travel industry officials we interviewed in six Visa Waiver Program countries praised DHS’s widespread ESTA outreach efforts, reasonable implementation time frames, and responsiveness to feedback, but expressed dissatisfaction over ESTA fees paid by ESTA applicants.

In 2010, airlines complied with the requirement to verify ESTA approval for almost 98 percent of the Visa Waiver Program passengers prior to boarding, but the remaining 2 percent—about 364,000 travelers—traveled under the Visa Waiver Program without verified ESTA approval. In addition, about 650 of these passengers traveled to the United States with a denied ESTA. As we reported in May 2011, DHS had not yet completed a review of these cases to know to what extent they pose a risk to the program. At the time of our report, DHS officials told us that there was no official agency plan for monitoring and oversight of ESTA. DHS tracked some data on passengers that traveled under the Visa Waiver Program without verified ESTA approval but did not track other data that would help officials know the extent to which noncompliance poses a risk to the program. Without a completed analysis of noncompliance with ESTA requirements, DHS was unable to determine the level of risk that noncompliance poses to Visa Waiver Program security and to identify improvements needed to minimize noncompliance. In addition, without analysis of data on travelers who were admitted to the United States without a visa after being denied by ESTA, DHS could not determine the extent to which ESTA was accurately identifying individuals who should be denied travel under the program. In May 2011, we recommended that DHS establish time frames for the regular review and documentation of cases of Visa Waiver Program passengers traveling to a U.S. port of entry without verified ESTA approval. DHS concurred with our recommendation and has established procedures to review quarterly a sample of noncompliant passengers to evaluate potential security risks associated with the ESTA program.

Further, in May 2011, we reported that to meet certain statutory requirements, DHS requires that Visa Waiver Program countries enter into three information-sharing agreements with the United States; however, only about half of the countries had fully complied with this requirement and many of the signed agreements have not been implemented. The 9/11 Act specifies that each Visa Waiver Program country must enter into agreements with the United States to share information regarding whether citizens and nationals of that country traveling to the United States represent a threat to the security or welfare of the United States and to report lost or stolen passports. DHS, in consultation with other agencies, has determined that Visa Waiver Program countries can satisfy the requirement by entering into the following three bilateral agreements: (1) Homeland Security Presidential Directive (HSPD) 6, (2) Preventing and Combating Serious Crime (PCSC), and (3) Lost and Stolen Passports.

HSPD-6 agreements establish a procedure between the United States and partner countries to share watchlist information about known or suspected terrorists. As of January 2011, 19 of the 36 Visa Waiver Program countries had signed HSPD-6 agreements, and 13 had begun sharing information according to the signed agreements. Noting that the federal government continues to negotiate HSPD-6 agreements with Visa Waiver Program countries, officials cited concerns regarding privacy and data protection expressed by many Visa Waiver Program countries as reasons for the delayed progress. According to these officials, in some cases, domestic laws of Visa Waiver Program countries limit their ability to commit to sharing some information, thereby complicating and slowing the negotiation process. In March 2012, DHS reported that 24 of the 36 Visa Waiver Program countries have signed HSPD-6 agreements.

The PCSC agreements establish the framework for law enforcement cooperation by providing each party automated access to the other’s criminal databases that contain biographical, biometric, and criminal history data. As of January 2011, 18 of the 36 Visa Waiver Program countries had met the PCSC information-sharing agreement requirement, but the networking modifications and system upgrades required to enable this information sharing to take place have not been completed for any Visa Waiver Program countries. According to officials, DHS is frequently not in a position to influence the speed of PCSC implementation for a number of reasons. For example, according to DHS officials, some Visa Waiver Program countries require parliamentary ratification before implementation can begin. Also, U.S. and partner country officials must develop a common information technology architecture to allow queries between databases. DHS reported in March 2012 that the number of Visa Waiver Program countries meeting the PCSC requirement had risen to 23.

The 9/11 Act requires Visa Waiver Program countries to enter into an agreement with the United States to report, or make available to the United States through Interpol or other means as designated by the Secretary of Homeland Security, information about the theft or loss of passports. As of March 2012, all Visa Waiver Program countries were sharing lost and stolen passport information with the United States, and all of the countries had entered into Lost and Stolen Passport agreements, according to DHS.

DHS, with the support of interagency partners, established a compliance schedule requiring the last of the Visa Waiver Program countries to finalize these agreements by June 2012. Although termination from the Visa Waiver Program is one potential consequence for countries not complying with the information-sharing agreement requirement, U.S. officials have described it as undesirable. DHS, in coordination with the Department of State and the Department of Justice, developed measures short of termination that could be applied to countries not meeting their compliance date. Specifically, DHS helped write a classified strategy document that outlines a contingency plan listing possible measures short of termination from the Visa Waiver Program that may be taken if a country does not meet its specified compliance date for entering into information-sharing agreements. The strategy document provides steps that would need to be taken prior to selecting and implementing one of these measures. According to officials, DHS plans to decide which measures to apply on a case-by-case basis.

In addition, as of May 2011, DHS had not completed half of the most recent biennial reports on Visa Waiver Program countries’ security risks in a timely manner. In 2002, the Enhanced Border Security and Visa Entry Reform Act mandated that, at least once every 2 years, DHS evaluate the effect of each country’s continued participation in the program on the security, law enforcement, and immigration interests of the United States.counterterrorism capabilities and immigration programs. However, DHS had not completed the latest biennial reports for 18 of the 36 Visa Waiver Program countries in a timely manner, and over half of these reports are more than 1 year overdue. Further, in the case of 2 countries, DHS was unable to demonstrate that it had completed reports in the last 4 years. DHS cited a number of reasons for the reporting delays. For example, DHS officials said that they intentionally delayed report completion because they frequently did not receive mandated intelligence assessments in a timely manner and needed to review these before completing Visa Waiver Program country biennial reports. We noted that DHS had not consistently submitted these reports in a timely matter since the legal requirement was made biennial in 2002, and recommended that DHS take steps to address delays in the biennial country review process so that the mandated country reports can be completed on time. DHS concurred with our recommendation and, in March 2012, reported that the Visa Waiver Program Office had implemented a reporting process and schedule to address delays in completing the biennial reviews and associated reports.

Federal Agencies Take Actions against a Small Portion of the Estimated Overstay Population

ICE Investigates Few In- Country Overstays, but Its Efforts Could Benefit from Improved Planning

As we reported in April 2011, ICE CTCEU investigates and arrests a small portion of the estimated in-country overstay population due to, among other things, ICE’s competing priorities; however, these efforts could be enhanced by improved planning and performance management. CTCEU, the primary federal entity responsible for taking enforcement action to address in-country overstays, identifies leads for overstay cases; takes steps to verify the accuracy of the leads it identifies by, for example, checking leads against multiple databases; and prioritizes leads to focus on those the unit identifies as being most likely to pose a threat to national security or public safety. CTCEU then requires field offices to initiate investigations on all priority, high-risk leads it identifies.

According to CTCEU data, as of October 2010, ICE field offices had closed about 34,700 overstay investigations that CTCEU headquarters assigned to them from fiscal year 2004 through 2010. These cases resulted in approximately 8,100 arrests (about 23 percent of the 34,700 investigations), relative to a total estimated overstay population of 4 million to 5.5 million. About 26,700 of those investigations (or 77 percent) resulted in one of three outcomes. In 9,900 investigations, evidence was uncovered indicating that the suspected overstay had departed the United States. In 8,600 investigations, evidence was uncovered indicating that the subject of the investigation was in-status (e.g., the subject filed a timely application with the United States Citizenship and Immigration Services (USCIS) to change his or her status and/or extend his or her authorized period of admission in the United States). Finally, in 8,200 investigations, CTCEU investigators exhausted all investigative leads and could not locate the suspected overstay. Of the approximately 34,700 overstay investigations assigned by CTCEU headquarters that ICE field offices closed from fiscal year 2004 through 2010, ICE officials attributed the significant portion of overstay cases that resulted in a departure finding, in-status finding, or with all leads being exhausted generally to difficulties associated with locating suspected overstays and the timeliness and completeness of data in DHS’s systems used to identify overstays.

Further, ICE reported allocating a small percentage of its resources in terms of investigative work hours to overstay investigations since fiscal year 2006, but the agency expressed an intention to augment the resources it dedicates to overstay enforcement efforts moving forward. Specifically, from fiscal years 2006 through 2010, ICE reported devoting from 3.1 to 3.4 percent of its total field office investigative hours to CTCEU overstay investigations. ICE attributed the small percentage of investigative resources it reported allocating to overstay enforcement efforts primarily to competing enforcement priorities. According to the ICE Assistant Secretary, ICE has resources to remove 400,000 aliens per year, or less than 4 percent of the estimated removable alien population in the United States. In June 2010, the Assistant Secretary stated that ICE must prioritize the use of its resources to ensure that its efforts to remove aliens reflect the agency’s highest priorities, namely nonimmigrants, including suspected overstays, who are identified as high risk in terms of being most likely to pose a risk to national security or public safety. As a result, ICE dedicated its limited resources to addressing overstays it identified as most likely to pose a potential threat to national security or public safety and did not generally allocate resources to address suspected overstays that it assessed as non- criminal and low risk. ICE indicated it may allocate more resources to overstay enforcement efforts moving forward, and that it planned to focus primarily on suspected overstays who ICE has identified as high risk or who recently overstayed their authorized periods of admission.

ICE was considering assigning some responsibility for noncriminal overstay enforcement to its Enforcement and Removal Operations (ERO) directorate, which has responsibility for apprehending and removing aliens who do not have lawful immigration status from the United States. However, ERO did not plan to assume this responsibility until ICE assessed the funding and resources doing so would require. ICE had not established a time frame for completing this assessment. We reported in April 2011 that by developing such a time frame and utilizing the assessment findings, as appropriate, ICE could strengthen its planning efforts and be better positioned to hold staff accountable for completing the assessment. We recommended that ICE establish a target time frame for assessing the funding and resources ERO would require in order to assume responsibility for civil overstay enforcement and use the results of that assessment. DHS officials agreed with our recommendation and stated that ICE planned to identify resources needed to transition this responsibility to ERO as part of its fiscal year 2013 resource planning process.

More Reliable, Accessible Data Could Improve DHS’s Efforts to Identify and Share Information on Overstays

DHS has not yet implemented a comprehensive biometric system to match available information provided by foreign nationals upon their arrival and departure from the United States. In 2002, DHS initiated the United States Visitor and Immigrant Status Indicator Technology Program (US-VISIT) to develop a comprehensive entry and exit system to collect biometric data from aliens traveling through U.S. ports of entry. In 2004, US-VISIT initiated the first step of this program by collecting biometric data on aliens entering the United States. In August 2007, we reported that while US-VISIT biometric entry capabilities were operating at air, sea, and land ports of entry, exit capabilities were not, and that DHS did not have a comprehensive plan or a complete schedule for biometric exit implementation. Moreover, in November 2009, we reported that DHS had not adopted an integrated approach to scheduling, executing, and tracking the work that needed to be accomplished to deliver a comprehensive exit solution as part of the US-VISIT program. We concluded that, without a master schedule that was integrated and derived in accordance with relevant guidance, DHS could not reliably commit to when and how it would deliver a comprehensive exit solution or adequately monitor and manage its progress toward this end. We recommended that DHS ensure that an integrated master schedule be developed and maintained. DHS concurred and reported, as of July 2011, that the documentation of schedule practices and procedures was ongoing, and that an updated schedule standard, management plan, and management process that are compliant with schedule guidelines were under review.

In the absence of a comprehensive biometric entry and exit system for identifying and tracking overstays, US-VISIT and CTCEU primarily analyze biographic entry and exit data collected at land, air, and sea ports of entry to identify overstays. In April 2011, we reported that DHS’s efforts to identify and report on visa overstays were hindered by unreliable data. Specifically, CBP does not inspect travelers exiting the United States through land ports of entry, including collecting their biometric information, and CBP did not provide a standard mechanism for nonimmigrants departing the United States through land ports of entry to remit their arrival and departure forms. Nonimmigrants departing the United States through land ports of entry turn in their forms on their own initiative. According to CBP officials, at some ports of entry, CBP provides a box for nonimmigrants to drop off their forms, while at other ports of entry departing nonimmigrants may park their cars, enter the port of entry facility, and provide their forms to a CBP officer. These forms contain information, such as arrival and departure dates, used by DHS to identify overstays. If the benefits outweigh the costs, a standard mechanism to provide nonimmigrants with a way to turn in their arrival and departure forms could help DHS obtain more complete and reliable departure data for identifying overstays. We recommended that the Commissioner of CBP analyze the costs and benefits of developing a standard mechanism for collecting these forms at land ports of entry, and do so to the extent that benefits outweigh the costs. CBP agreed with our recommendation and in September 2011 stated that it planned to complete a cost-effective independent evaluation of possible solutions and formulate an action plan based on the evaluation for implementation by March 2012.

Further, we previously reported on weaknesses in DHS processes for collecting departure data, and how these weaknesses impact the determination of overstay rates. The 9/11 Act required that DHS certify that a system is in place that can verify the departure of not less than 97 percent of foreign nationals who depart through U.S. airports in order for DHS to expand the Visa Waiver Program. In September 2008, we reported that DHS’s methodology for comparing arrivals and departures for the purpose of departure verification would not inform overall or country-specific overstay rates because DHS’s methodology did not begin with arrival records to determine if those foreign nationals departed or remained in the United States beyond their authorized periods of admission. Rather, DHS’s methodology started with departure records and matched them to arrival records. As a result, DHS’s methodology counted overstays who left the country, but did not identify overstays who have not departed the United States and appear to have no intention of leaving. We recommended that DHS explore cost-effective actions necessary to further improve the reliability of overstay data. DHS concurred and reported that it is taking steps to improve the accuracy and reliability of the overstay data, by efforts such as continuing to audit carrier performance and working with airlines to improve the accuracy and completeness of data collection. Moreover, by statute, DHS is required to submit an annual report to Congress providing numerical estimates of the number of aliens from each country in each nonimmigrant classification who overstayed an authorized period of admission that expired during the fiscal year prior to the year for which the report is made.provided Congress annual overstay estimates regularly since 1994 because officials do not have sufficient confidence in the quality of the department’s overstay data—which is maintained and generated by US- VISIT. As a result, DHS officials stated that the department cannot reliably report overstay rates in accordance with the statute.

DHS officials stated that the department has not In addition, in April 2011 we reported that DHS took several steps to provide its component entities and other federal agencies with information to identify and take enforcement action on overstays, including creating biometric and biographic lookouts—or electronic alerts—on the records of overstay subjects that are recorded in databases. However, DHS did not create lookouts for the following two categories of overstays: (1) temporary visitors who were admitted to the United States using nonimmigrant business and pleasure visas and subsequently overstayed by 90 days or less; and (2) suspected in-country overstays who CTCEU deems not to be a priority for investigation in terms of being most likely to pose a threat to national security or public safety. Broadening the scope of electronic lookouts in federal information systems could enhance overstay information sharing. In April 2011, we recommended that the Secretary of Homeland Security direct the Commissioner of Customs and Border Protection, the Under Secretary of the National Protection and Programs Directorate, and the Assistant Secretary of Immigration and Customs Enforcement to assess the costs and benefits of creating biometric and biographic lookouts for these two categories of overstays. Agency officials agreed with our recommendation and have actions under way to address it. For example, agency officials stated that they have met to assess the costs and benefits of creating lookouts for those categories of overstays.

Chairman Schumer, Ranking Member Cornyn, and Members of the Subcommittee, this concludes my prepared statement. I would be pleased to respond to any questions that you may have.
