Colorado State University said on Wednesday that an additional student had their visa revoked after several were revoked a day earlier. The Department of State acknowledged the move but won't say why they were revoked.

Students at the University of Colorado and Colorado State University have lost their visas, following a wave of high-profile arrests of international students across the country.

At least nine students between the University of Colorado and Colorado State University have had their student visas revoked by the Department of Homeland Security, spokespeople for the schools have said.
