The Obama administration is cracking down on immigrants in the U.S. who have overstayed the terms of their visas by using a system that automatically checks multiple national security, immigration, and law enforcement databases at the same time, a Homeland Security Department official tells the Associated Press. The common practice has been to make manual checks of individual databases. The new system has already identified dozens of investigative leads, said John Cohen, deputy counterterrorism coordinator at the Homeland Security Department.
The immediate focus is on identifying people who have overstayed their visas and who pose a potential threat to national security or public safety, Cohen said. Some of the 19 Sept. 11 hijackers were in the U.S. in violation of their visas, and in one case because the hijacker did not attend a school he said he would on his application for a student visa. The 9/11 Commission saw the visa system as a major vulnerability and recommended completing a biometric system that would log immigrants out as they left the U.S. This program was never fully implemented. Homeland Security Secretary Janet Napolitano has said the exit system called for by the commission is expensive, and the government has put other policies in place since 2001 to address the same issue for a lot less money. Automating these checks is the latest of those policies.
