The ICE claims the school issued F-1 visas to students who lived outside California. From May 2009 to May 2010, the school went from having 11 students with F1 visas to 939 students with F1 visas. The number went to 1555 in December 2010. 90% of the students were from India. Students paid up to $2700/semester for tuition.

The US Attorney filed suit to forfeit five properties owned by Susan Su relating to the school.Foreign students, mostly from India, were interrogated by the ICE. Some were radio tagged to monitor their movements, a move the Indian government protested as treating the students who had been tricked by TVU's promoters like common criminals.
