The total number of asylum applications, including both principal applicants and their eligible dependents, filed in fiscal year 2014 (108,152) is more than double the number filed in fiscal year 2010 (47,118). As of September 2015, the Department of Homeland Security's (DHS) U.S. Citizenship and Immigration Services (USCIS) has a backlog of 106,121 principal applicants, of which 64,254 have exceeded required time frames for adjudication. USCIS plans to hire additional staff to address the backlog.USCIS and the Department of Justice's (DOJ) Executive Office for Immigration Review (EOIR) have limited capabilities to detect asylum fraud. First, while both USCIS and EOIR have mechanisms to investigate fraud in individual applications, neither agency has assessed fraud risks across the asylum process, in accordance with leading practices for managing fraud risks. Various cases of fraud illustrate risks that may affect the integrity of the asylum system. For example, an investigation in New York resulted in charges against 30 defendants as of March 2014 for their alleged participation in immigration fraud schemes; 829 applicants associated with the attorneys and preparers charged in the case received asylum from USCIS, and 3,709 received asylum from EOIR. Without regular assessments of fraud risks, USCIS and EOIR lack reasonable assurance that they have implemented controls to mitigate those risks. Second, USCIS's capability to identify patterns of fraud across asylum applications is hindered because USCIS relies on a paper-based system for asylum applications and does not electronically capture some key information that could be used to detect fraud, such as the applicant's written statement. Asylum officers and USCIS Fraud Detection and National Security (FDNS) Directorate immigration officers told GAO that they can identify potential fraud by analyzing trends across asylum applications; however, they must rely on labor-intensive methods to do so. Identifying and implementing additional fraud detection tools could enable USCIS to detect fraud more effectively while using resources more efficiently. Third, FDNS has not established clear fraud detection responsibilities for its immigration officers in asylum offices; FDNS officers we spoke with at all eight asylum offices told GAO they have limited guidance with respect to fraud. FDNS standard operating procedures for fraud detection are intended to apply across USCIS, and therefore do not reflect the unique features of the asylum system. Developing asylum-specific guidance for fraud detection, in accordance with federal internal control standards, would better position FDNS officers to understand their roles and responsibilities in the asylum process.To address identified instances of asylum fraud, USCIS can, in some cases, terminate an individual's asylum status. USCIS terminated the asylum status of 374 people from fiscal years 2010 through 2014 for fraud. In August 2015, USCIS adopted a target of 180 days for conducting initial reviews, in which the asylum office reviews evidence and decides whether to begin termination proceedings, when the asylee has applied for adjustment to lawful permanent resident status; however, this goal applies only to a subset of asylees and pertains to initial reviews. Further, asylees with pending termination reviews may be eligible to receive certain federal benefits. Developing timeliness goals for all pending termination reviews would help USCIS better identify the staffing resources needed to address the terminations workload.
