REPORTS: FEDS LOSE TRACK OF 6,000 FOREIGNERS ON STUDENT VISAS WHO COULD 'DO US HARM'

The federal government has reportedly lost track of more than 6,000 foreigners on student visas, some of whom may be in the country "to do us harm."

According to an ABC News investigation, "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." ABC found that "the number of foreign nationals obtaining visas to study in the U.S. has grown from 662,966 in 2003 to more than 1.2 million in 2012."

Peter Edge, "the U.S. Immigration and Customs Enforcement official who oversees investigations into visa violators," told ABC News that some of the foreign nationals "could be here to do us harm" and his "greatest concern is that they could be doing anything."
