The Department of Homeland Security is now collecting fingerprints from international visitors arriving at Washington Dulles. The change is part of the department's upgrade from two- to 10-fingerprint collection to enhance security and fingerprint matching accuracy. Nine other airports will begin 10-fingerprint collection during the next few months, including Atlanta Hartsfield, Chicago O'Hare and New York Kennedy.Under the expanded screening, officers collect prints from all non-U.S. citizens between the ages of 14 and 79 when they apply for visas or arrive at U.S. ports of entry, with some exceptions. The department's US-VISIT program then checks this data against a joint FBI/DHS watch list of criminals, immigration violators and known or suspected terrorists. The 278 remaining ports will begin this process by the end of 2008. (DB)
