The Immigration and Nationality Act (INA), as amended, is the primary body of law governing immigration and visa operations. Among other things, the INA defines the powers given to the Secretaries of State and Homeland Security and the consular and immigration officers who serve under them, delineates categories of and qualifications for immigrant and nonimmigrant visas, and provides a broad framework of operations through which foreign citizens are allowed to enter and immigrate to the United States. USCIS is generally responsible for administering the citizenship and immigration services of the United States. Most foreign nationals living abroad who wish to immigrate to the United States must obtain a visa through the Department of State's Bureau of Consular Affairs. U.S. citizens and lawful permanent residents, that is, petitioners, can request or petition USCIS to allow certain relatives to immigrate to the United States. As the first step in a two step process, petitioners must file a family-based petition with USCIS. U.S. citizens and lawful permanent residents may file a Form I-130 for an alien relative, such as a wife or child, to immigrate to the United States. U.S. citizens (but not lawful permanent residents) may also petition to bring a noncitizen fiance(e) to the United States by filing a Form I-129F with USCIS. The I-129F or I-130 petitions may also list "derivative beneficiaries," such as the beneficiary's unmarried child under 21 years old, who are eligible to immigrate with the primary beneficiary. The purpose of these petitions is to establish the petitioner's relationship to the family member or fiance(e) who wishes to immigrate to the United States. USCIS adjudicators are to review petitions and make determinations, in accordance with immigration law, on whether to approve or deny petitions. If a petition is approved, the second step in the process is to determine whether the noncitizen is admissible under immigration law to enter or remain in the United States. If the noncitizen is overseas, USCIS will send the approved petition to the State Department and a State Department consular officer will determine whether to issue a visa to the noncitizen. If the noncitizen is already in the United States in a nonimmigrant status, such as a visitor or student, when the petition is approved, a USCIS adjudicator will determine whether to allow the noncitizen to change, or "adjust," his/her status to that of a lawful permanent resident. As part of its review, USCIS conducts background security checks on petitioners as well as noncitizen beneficiaries. These background checks were instituted for national security purposes such as identifying terrorists or terrorist threats, and for public safety reasons, such as identifying human rights violators or aggravated felons. According to USCIS officials, background security checks were conducted on all beneficiaries prior to September 11. As of January 2002, however, background security checks were required to be conducted on all petitioners, including U.S. citizens, as well as beneficiaries. USCIS adjudicators conduct background security checks using the Interagency Border Inspection System (IBIS), which is a multi-agency computer system of lookouts for terrorists, drug traffickers, and other such criminal types. IBIS contains numerous database files and interfaces with sources such as the FBI's National Crime Information Center. The NCIC contains various data, including data on violent gangs and terrorists, immigration violators, and the National Sex Offender Registry. During a background check, if an IBIS query returns a "hit" where the name and date of birth information entered returns a positive response from one or more of the databases, and it appears the petitioner may have a criminal background, USCIS adjudicators are to forward this information to a Fraud Detection and National Security (FDNS) officer within USCIS. FDNS officers are to conduct further system searches for verification of the criminal hits. After researching and summarizing the criminal data on the petitioner, FDNS officers are to notate their findings in a resolution memorandum and send the memo back to the adjudicator responsible for the file. Assuming the petitioner cannot be referred to law enforcement or, in the case of a lawful permanent resident, deported, the adjudicator then continues the review and accepts or denies the petition based on whether there appears to be a valid relationship between the petitioner and the beneficiary. The FBI NCIC NSOR is a compilation of state registration information about sex offenders. The NSOR is statutorily mandated by the Pam Lychner Sexual Offender Tracking and Identification Act of 1996. The act directs the Attorney General to establish a national database at the FBI to track the whereabouts and movement of (1) each person who has been convicted of a "criminal offense against a victim who is a minor," (2) each person who has been convicted of a "sexually violent offense," and (3) each person who is determined to be a "sexually violent predator." As implemented, the NSOR is a nationwide system that links states' sex offender registration and notification programs. Each of the 50 states and the District of Columbia has created a sex offender registry based on the above three conviction categories and has established an interface with the FBI's national system in order to transmit state registry information to the national registry. State registries contain information on sex offenders who are required to register and that reside, work, or attend school within the state. At least 398 convicted sex offenders filed petitions for spouses, fiance(e)s, children, and other relatives in fiscal year 2005 based upon matching several data elements from USCIS's database with data from FBI's National Sex Offender Registry. There may be additional convicted sex offenders who filed family-based petitions. For example, we could not determine with a high degree of confidence whether 53 petitioners that had the same name and date of birth as a person in the NSOR were the same individuals because there were no additional data items, such as Social Security number or address, that we could match. Therefore, we did not include these additional 53 petitioners in our count because it is possible that two people could have the same name and date of birth. The 398 sex offenders filed a total of 420 petitions. Figure 1 shows the type of beneficiaries for which petitions were filed by convicted sex offenders. USCIS data indicate that 371 (88 percent) of the beneficiaries were spouses and fiance(e)s, 33 (8 percent) were unmarried children under 21 years old, and 16 (4 percent) were classified as other relatives. We do not know, however, what percentage of unmarried children under 21 years old were minors under the federal criminal code, which defines a minor as under 18 years old for purposes of certain child sexual offenses. In addition, certain relatives of the primary beneficiary, such as unmarried children, under 21 years old, of the noncitizen spouse or fiance(e), called derivative beneficiaries, may also immigrate with the beneficiary. However, USCIS's data system only includes information on the primary beneficiary, not on any derivative beneficiaries. Therefore, our data underestimate the actual number of beneficiaries. For example, in addition to the 33 unmarried children under 21 years of age that were the primary beneficiaries of sex offenders, the State Department provided us data from its visa processing system indicating that there were at least an additional 27 children who were derivative beneficiaries associated with fiance(e) petitions. Both USCIS and State Department data together total at least 60 unmarried children under 21 years of age. As shown in table 1, some of the sex offenders have been convicted of multiple sex crimes. The 398 sex offenders were convicted of at least 411 sex offenses, including sexual assault, rape, and child molestation, according to conviction data contained in the NSOR. At least 45 of the convictions were for sex offenses against children. It is possible that more than 45 convictions involved sex offenses against children, but this number could not be determined based on the conviction description in the registry. For example, the conviction description for 217 of the 411 convictions, or 53 percent, is "sex offense." In addition, 14 petitioners were classified as sexual predators. Consistent with statute, the NSOR classifies "sexual predator" as an offender who has been convicted of a sexually violent offense and suffers from a mental abnormality or personality disorder that makes the person likely to engage in predatory sexually violent offenses again. These 14 sexual predators filed a total of 17 petitions. As of December 2005, 9 of the 17 petitions filed were approved and 8 were pending. Three of the 14 petitioners who were classified as sexual predators filed for unmarried children under 21 years old. Convicted sex offenders are not prohibited by the INA from petitioning to bring their spouses, fiance(e)s, or children into the United States. According to USCIS and the Department of State, neither agency has general authority to deny a petition or visa based solely on the fact that a petitioner may be a convicted sex offender. In a December 2005 letter to GAO, USCIS's Acting Chief Counsel stated that USCIS may not reject or deny family-based petitions on the grounds that the petitioner has a criminal background, lacks good moral character, or other possible negative factors. The review and ultimately the approval of such petitions centers on whether the facts stated in the petition are true and whether there exists the requisite relationship between the petitioner and the beneficiary. It is possible that a petitioner's criminal history may be relevant to the question of whether the petitioner has established the requisite relationship. For example, a petitioner's conviction for fraud, bigamy, or alien smuggling would be relevant in determining whether a bona fide relationship exists between the petitioner and a noncitizen spouse beneficiary. According to officials in the Department of State's Bureau of Consular Affairs, the Department of State cannot deny a visa to a noncitizen based solely on the fact that the petitioner is a convicted sex offender or has other criminal convictions. The review and ultimately the approval of a visa centers on whether the noncitizen is admissible under immigration law to enter the United States and on whether there exists the prerequisite relationship between the petitioner and the beneficiary. Therefore, consular officers have no legal basis to deny a visa to a noncitizen based solely on the fact that the petitioner has a criminal sexual background. In cases where there is no basis for denying a petition or visa, both the State Department and USCIS may be faced with the issue of whether, and under what circumstances, they can disclose the petitioner's criminal sexual history to a beneficiary consistent with any applicable privacy restrictions. According to both USCIS and Department of State officials, the compelling circumstances exception to the Privacy Act of 1974 provides authority to disclose a petitioner's criminal sexual history to a noncitizen beneficiary on a case-by-case basis. For certain noncitizen beneficiaries, disclosure of the petitioner's criminal background information is mandatory based on new authority granted to USCIS and the Department of State. The recently enacted International Marriage Broker Regulation Act (IMBRA) of 2005 requires disclosure of a U.S. citizen's criminal background information, including sex crimes, to certain prospective immigrants, essentially noncitizen fiance(e)s, but some spouses and children as well. USCIS must furnish this criminal background information to the Department of State for purposes of making IMBRA disclosures. On May 3, 2006, USCIS officials issued interim guidance to its adjudicators on making disclosures under the compelling circumstances exception to the Privacy Act and stated that USCIS would soon issue additional guidance with respect to IMBRA disclosures. The Department of State informed us that it is preparing to issue disclosure guidance to consular officers that will cover discretionary Privacy Act disclosures and that it is finalizing separate disclosure guidance with respect to the mandatory disclosures required under IMBRA., but this guidance cannot be issued until USCIS finalizes its IMBRA related procedures. The Privacy Act of 1974 states that, "no agency shall disclose any record which is contained in a system of records by any means of communication to any person, or to another agency, except pursuant to a written request by, or with the prior written consent of, the individual to whom the record pertains." While information from the covered systems is generally not to be disclosed, there are 12 exceptions. One of these exceptions authorizes an agency to make a disclosure "to a person pursuant to a showing of compelling circumstances affecting the health or safety of an individual if upon such disclosure notification is transmitted to the last known address of such individual." Both USCIS and the Department of State have interpreted the compelling circumstances exception in the Privacy Act as authority to permit the disclosure of a petitioner's criminal sexual history information. In a December 2005 letter to GAO, USCIS's Acting Chief Counsel stated that if USCIS learns that a petitioner has a substantiated history of sexual assault or child molestation, then USCIS has the discretion in compelling circumstances to disclose that information to the beneficiary. On May 3, 2006, USCIS issued Privacy Act interim guidance advising adjudicators of when it may be appropriate to disclose a petitioner's criminal history involving violence or sex offenses to potential visa beneficiaries under the compelling circumstances exception. Generally, disclosure is limited to those portions of the petitioner's criminal history involving violence or sex offenses that are directly relevant to the "health and safety" of the potential beneficiary. As an example, the guidance provides that normally, "a conviction as a sexual predator should be considered a compelling circumstance affecting the health and safety of a child who would reside with the sexual predator." The guidance further states that any concerns about safety that adjudicators have that are outside the scope of the guidance should be brought to the attention of their supervisor. According to Department of State officials, protecting the health or safety of a minor child would constitute compelling circumstances to disclose a petitioner's criminal sex offender background, though the exception might also apply in cases that did not involve a minor child. In a letter to GAO, the Chief, Advisory Opinions Branch, of the Department of State's Visa Office wrote, "the clear possibility of abuse that an immigrant child would face while living in the same household as a convicted sex offender provides a strong basis for applying the health and safety exception in these cases." The Department of State asserts that its position is "consistent with overall U.S. policy balancing the need to inform the public of the potential threat to a community posed by a child sex offender with the privacy interests of the offender." According to the Department, consular officials are to consult with the department's visa policy and legal staff prior to disclosure of a criminal record or other negative factors. For certain noncitizen beneficiaries, disclosure of the petitioner's criminal background information is now mandatory based on new authority granted to USCIS and the Department of State. The recently enacted International Marriage Broker Regulation Act of 2005 requires disclosure of a U.S. citizen's criminal background information, including sex crimes, to certain prospective immigrants, essentially noncitizen fiance(e)s, but also some spouses and children (i.e., unmarried children under 21 years old who are derivatives of the primary beneficiary). IMBRA mandates disclosure of a U.S. citizen's criminal history, including sex crimes, to certain prospective immigrants known as K nonimmigrant visa applicants, who are essentially noncitizen fiance(e)s, but also some spouses and children. Obtaining a K visa allows the fiance(e), spouse, or child to enter the United States as a nonimmigrant and then apply for immigrant (i.e., lawful permanent resident) status while in this country. Under section 832 of IMBRA, USCIS must revise its I-129F petition to require petitioners to disclose criminal background information for numerous specified crimes, including domestic violence, sexual assault, child abuse and neglect, and incest. Any criminal background information USCIS possesses with respect to the petitioner must accompany any approved petition that is forwarded to the Department of State. IMBRA goes on to provide: "The Secretary of State, in turn, shall share any such criminal background information that is in government records or databases with the K nonimmigrant visa applicant who is the beneficiary of the petition. The visa applicant shall be informed that such criminal background information is based on available records and may not be complete." To effectuate IMBRA's mandatory disclosure requirement, the Department of State must mail the visa applicant a copy of the petition, including any criminal background information, as well as a government- developed domestic violence information pamphlet. Supplementing the disclosure by mail, IMBRA also requires Department of State consular officers to "provide for the disclosure of such criminal background information to the visa applicant at the consular interview in the primary language of the visa applicant." IMBRA's mandatory disclosure requirement only extends to fiance(e)s, spouses, and their minor children (i.e., unmarried children under 21 years old), who are sponsored by U.S. citizens and enter the United States on a K nonimmigrant visa issued by the Department of State. IMBRA's mandatory disclosure requirement does not cover (1) the spouses and minor children of lawful permanent residents, who do not have the option of entering the United States using a K visa; (2) the spouses and minor children of U.S. citizens who enter the United States on an immigrant visa; or (3) any noncitizen already in the United States applying directly to USCIS for immigrant status. According to the data we reviewed, most noncitizens entering under family-based petitions will not be covered by IMBRA's mandatory disclosure requirement. In fiscal year 2005, about 80 percent of all family-based petitions filed were for other than K visas. USCIS issued interim guidance related to Privacy Act disclosures on May 3, 2006. The guidance advises adjudicators of when "compelling circumstances" may exist to disclose a petitioner's criminal history involving violence or sex offenses: for example, protecting the health and safety of a child beneficiary who would reside with a sexual predator would normally constitute a compelling circumstance to make a disclosure. The guidance states that disclosure should be limited only to those portions of the petitioner's criminal history that are directly relevant to the health and safety of the potential beneficiary. The guidance also contains Privacy Act procedures that adjudicators must follow when they make a disclosure, such as providing written notice of the disclosure to the petitioner and annotating the USCIS file to maintain a record of the disclosure and the justification for it. When the beneficiary is within USCIS's jurisdiction, the guidance informs adjudicators to make disclosures during in-person interviews with the beneficiary. When the beneficiary is abroad, the guidance requires the adjudicator to provide to the State Department any adverse information that might affect the health or safety of a beneficiary to enable the State Department to make a decision regarding disclosure. USCIS's interim guidance related to Privacy Act disclosure states that USCIS will issue separate guidance addressing the special procedures adjudicators must follow with respect to I-129F petitions. As previously discussed, to meet IMBRA requirements, USCIS must revise its I-129F petition to require petitioners to disclose criminal background information for numerous specified crimes, including sex offenses. Any criminal background information USCIS possesses with respect to the petitioner must accompany any approved petition that is forwarded to the State Department to enable the State Department to effectuate IMBRA's mandatory disclosure requirement. IMBRA mandated that USCIS revise its I-129F petition by March 6, 2006 (60 days after IMBRA's January 5 enactment). USCIS has not yet revised the petition. USCIS officials told us that they have been reviewing and consolidating suggested revisions to the I-129F, including IMBRA-related changes, and expect publication of the new Form I-129F in the Federal Register in mid-June 2006. Department of State officials told us that they had drafted guidance for consular officers that addresses the disclosure of a petitioner's criminal sexual offender background under the compelling circumstances exception to the Privacy Act. According to the Department of State, the draft guidance was essentially ready for issuance when IMBRA, which mandates disclosure of a petitioner's criminal history to certain beneficiaries, was enacted. As a result, it decided to revise its draft guidance to take the new statutory requirements into account. The officials said that they are preparing to issue disclosure guidance to consular officers that will cover discretionary Privacy Act disclosures not covered under IMBRA and are finalizing separate guidance with regard to the mandatory disclosures required under IMBRA. However, according to State Department officials, the IMBRA-related guidance cannot be issued until USCIS finalizes its IMBRA procedures, including revising the I-129F petition. Convicted sex offenders can sponsor noncitizen relatives, such as spouses, fiance(e)s, and children, for entry into the United States. Not all beneficiaries may know that their petitioner has a criminal sex offender history that may put the beneficiary at risk. Recently enacted legislation has mitigated this risk for certain beneficiaries by requiring the State Department, in cooperation with USCIS, to disclose the petitioner's criminal background information, including sex crimes. Both agencies said that they plan to issue guidance on the new mandatory disclosure requirement. For beneficiaries who are not covered by the mandatory disclosure requirement, both USCIS and the State Department interpret a Privacy Act exception as giving them discretion to disclose a petitioner's criminal sexual history based on "compelling circumstances affecting the health or safety" of the beneficiary. Until recently, neither agency had issued guidance on this authority, but USCIS has now issued interim guidance to its adjudicators addressing compelling circumstance disclosures, and the State Department is preparing to issue its guidance to consular officers regarding discretionary Privacy Act disclosures not covered by IMBRA. On the basis of the agencies' Privacy Act guidance, beneficiaries who are not statutorily protected by the mandatory disclosure requirement may nevertheless be informed of their petitioners' criminal sexual history and the possible risk to their safety. We requested comments on a draft of this report from the Secretaries of Homeland Security and State and the Attorney General. None of these officials provided formal comments. However, representatives from each of these departments provided technical comments which we incorporated into this report, as appropriate. We are sending copies of this report to the Secretaries of Homeland Security and State, the Attorney General, and interested congressional committees. We will also make copies available to others upon request. In addition, the report will be available at no charge on GAO's Web site at http://www.gao.gov. If you or your staff have any questions concerning this report, please contact me at (202) 512-8777 or Jonespl@gao.gov. Contact points for our Offices of Congressional Relations and Public Affairs may be found on the last page of this report. Key contributors to this report are listed in appendix II. To identify the number of convicted sex offenders who filed family-based petitions, we conducted a computer match of U.S. Citizenship and Immigration Services (USCIS) family-based petitioner data with data on individuals contained in the Federal Bureau of Investigation's (FBI) National Crime Information Center (NCIC) Convicted Sexual Offender Registry File, known as the National Sex Offender Registry. The USCIS petitioner data file contained records on 667,023 individuals who filed petitions for noncitizen relatives, such as a spouse or child, and 66,658 individuals who filed petitions for noncitizen fiance(e)s in fiscal year 2005. The FBI's NCIC National Sex Offender Registry contained data on the 412,773 convicted sex offenders as of December 2005. The USCIS and FBI data files contained seven common data elements: (1) name (2) date of birth, (3) Social Security number, (4) street address, (5) city, (6) state, and (7) ZIP code that we could attempt to match in order to determine which petitioners were registered sex offenders. The name and date of birth were always present in both datasets, but in some cases the other data elements in either the USCIS or FBI dataset were either missing or not entered correctly. In order to increase the possibility of a valid match, we first applied acceptable data-cleaning steps. For example, we eliminated certain extraneous characters from the names and addresses, such as dashes, periods and hyphens and other nonessential characters that would otherwise impede our matching. In addition, we corrected for certain obvious typographical errors, such as typing a zero instead of the letter O. We conducted our match in two steps. In the first step, we matched cases on name and Social Security number since the Social Security number is considered a unique identifier. For our purposes, if the name and Social Security number were the same in both cases, we considered it a match. In the second step, after eliminating those we matched based on name and Social Security number, we matched the remaining records on name and date of birth. It is possible for two people to have the same name and date of birth. Therefore, to be deemed a match for our purposes, the name, date of birth, and several data elements needed to match to provide a high level of assurance that the petitioner and the registered sex offender were the same person. For example, if the name, date of birth and street address, city, and ZIP code were the same, we considered it a match. We also analyzed the USCIS data set to determine the number of petitioners that may have filed more than one petition to arrive at the number of unique sex offenders. To determine the reliability of the USCIS data, we observed how petitioner data are entered into the USCIS data system, interviewed relevant USCIS officials and staff, reviewed pertinent documents, and performed electronic testing for obvious errors in accuracy and completeness. To determine the reliability of the FBI's Convicted Sexual Offender Registry File, we interviewed FBI officials and system programmers knowledgeable about the data, reviewed pertinent information regarding the FBI's sex offender registry, and performed electronic testing for obvious errors in accuracy and completeness. We determined that the data were sufficiently reliable for the purposes of this report. We conducted our work from August 2005 through June 2006 in accordance with generally accepted government auditing standards. In addition to the above, Michael Dino, Assistant Director, Carla Brown, Christine Davis, Katherine Davis, Darryl Dutton, Lemuel Jackson, and James Ungvarsky were key contributors to this report.

Summary:
In fiscal year 2005, U.S. citizens and lawful permanent residents filed about 730,000 petitions with the U.S. Citizenship and Immigration Services (USCIS) to sponsor noncitizen family members, including spouses, fiances, and children, to immigrate to the United States. Those doing the sponsoring are called petitioners; those benefiting from the sponsoring are called beneficiaries. If USCIS approves the petition, overseas beneficiaries must also file a visa application with the Department of State to enter the United States. In January 2002, USCIS started to conduct background security checks on all petitioners in addition to the beneficiaries. These background checks revealed that some of the petitioners had convictions for criminal sex offenses; further, some of those criminal sex offenders were filing family-based petitions for children (those under the age of 21). This report addresses the number of convicted sex offenders who filed family-based petitions in fiscal year 2005 based upon a computer match of USCIS data with individuals in the Federal Bureau of Investigation's National Sex Offender Registry and discusses USCIS's and the Department of State's framework for disclosing a sponsor's criminal sexual background to the beneficiary. DHS, the Department of State, and the Department of Justice reviewed a draft of this report. Only technical comments were provided and have been incorporated into this report. At least 398 convicted sex offenders filed a total of 420 petitions in fiscal year 2005 for spouses, fiances, children, and other relatives. Immigration law does not prohibit convicted sex offenders from petitioning to bring their spouses, fiances, or children into the United States and generally USCIS cannot deny a petition based solely on the fact that the petitioner is a convicted sex offender. The sex offenders were convicted of at least 411 sex-related crimes, including sexual assault and rape, according to data in the Federal Bureau of Investigation's National Sex Offender Registry. At least 45 convictions involved crimes against children. While most beneficiaries were spouses and fiances, criminal sex offenders petitioned for at least 60 children. According to USCIS and Department of State officials, an exception to the Privacy Act of 1974 gives them authority to disclose a petitioner's criminal sex offender history if there are "compelling circumstances affecting the health and safety" of the beneficiary. For certain noncitizen beneficiaries, disclosure of the petitioner's criminal background information is now mandatory based on new authority granted to USCIS and the Department of State. The International Marriage Broker Regulation Act of 2005 (IMBRA) requires disclosure of a U.S. citizen's criminal background information, including sex crimes, to certain prospective immigrants, essentially noncitizen fiances, but some spouses and minor children as well. Mandatory disclosure is not required for beneficiaries not covered by IMBRA, though these beneficiaries may receive information about a petitioner's criminal background on a discretionary basis under the Privacy Act exception. GAO estimates that IMBRA's mandatory disclosure requirement will cover about 20 percent of family-based beneficiaries based on fiscal year 2005 data. On May 3, 2006, USCIS issued interim guidance to its adjudicators on when it may be appropriate to disclose information related to a petitioner's criminal history under the "compelling circumstances" exception to the Privacy Act. USCIS plans to issue separate guidance related to disclosure requirements under IMBRA. Department of State officials said that they are preparing to issue Privacy Act disclosure guidance and are finalizing separate IMBRA disclosure guidance.
