"Each year, millions of visitors come to the United States legally on a temporary basis. Overstays are individuals who were admitted legally on a temporary basis but then overstayed their authorized periods of admission. The Intelligence Reform and Terrorism Prevention Act of 2004 required the Secretary of Homeland Security to develop a plan to accelerate implementation of a biometric entry and exit data system that matches information provided by foreign nationals upon their arrival and departure. Since 2004, DHS has tracked foreign nationals' entries into the United States, and since December 2006, a biometric entry capability has been fully operational at all ports of entry. However, GAO [Government Accountability Office] has identified a range of challenges that DHS has faced in its efforts to deploy a corresponding biometric exit capability. DHS's CBP [U.S. Customs and Border Protection] is primarily responsible for implementing a biometric exit program. This statement discusses the extent to which DHS has made progress in developing a biometric exit system and reporting overstay estimates. This statement is based on a report GAO issued in July 2013 (GAO-13-683), with selected updates conducted in January 2016 to obtain information from DHS on actions it has taken to address prior recommendations. GAO previously made recommendations to DHS to establish time frames and milestones for a biometric air exit evaluation framework and assess the reliability of its overstay data. DHS concurred with the recommendations, and has actions underway to address them."
