A letter report issued by the Government Accountability Office with an abstract that begins "The Department of Homeland Security (DHS) has established a program--the U.S. Visitor and Immigrant Status Indicator Technology (US-VISIT)--to collect, maintain, and share information, including biometric identifiers, on selected foreign nationals entering and exiting the United States. US-VISIT uses these identifiers (digital fingerscans and photographs) to screen persons against watch lists and to verify that a visitor is the person who was issued a visa or other travel document. Visitors are also to confirm their departure by having their visas or passports scanned and undergoing fingerscanning at selected air and sea ports of entry (POE). GAO has made many recommendations to improve the program, all of which DHS has agreed to implement. GAO was asked to report on DHS's progress in responding to 18 of these recommendations."
