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.

At least six international students at Colorado State University and four at CU have had their student visas revoked this semester, officials said.

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.
