Via ABC News:
The Department of Homeland Security has lost track of more than 6,000 foreign nationals who entered the United States on student visas, overstayed their welcome, and essentially vanished — exploiting a security gap that was supposed to be fixed after the Sept. 11, 2001 terror attacks.
“My greatest concern is that they could be doing anything,” said Peter Edge, the U.S. Immigration and Customs Enforcement official who oversees investigations into visa violators. “Some of them could be here to do us harm.”
Homeland Security officials disclosed the breadth of the student visa problem in response to ABC News questions submitted as part of an investigation into persistent complaints about the nation’s entry program for students.
ABC News found that immigration officials have struggled to keep track of the rapidly increasing numbers of foreign students coming to the U.S. — now in excess of one million each year. The immigration agency’s own figures show that 58,000 students overstayed their visas in the past year. Of those, 6,000 were referred to agents for follow-up because they were determined to be of heightened concern.
“They just disappear,” said Sen. Tom Coburn, R-Okla. “They get the visas and they disappear.”
Coburn said since the Sept. 11, 2001 terror attacks, 26 student visa holders have been arrested in the U.S. on terror-related charges.
