U.S. immigration officials July 29 raided the University of Northern Virginia, which bills itself as the most popular American college for Indian students, for allegedly failing to comply with federal regulations for administering foreign student visas.

Officials from the Immigration and Customs Enforcement Student and Exchange Visitor Program served UNVA officials in Annandale, Va., with a notice of intent to withdraw the college’s ability to accept foreign students. The college now has 30 days to respond to the ICE notice. Almost 90 percent of UNVA’s students are from Andhra Pradesh.

ICE has set up a Website for UNVA students, informing them that they may continue to attend classes at UNVA if they attend school full-time and do not work. UNVA students also have the option of transferring to another university approved by ICE, or leaving the country.
