The revocations began last week and none of the CU students have been detained at this point, university spokeswoman Michele Ames said Wednesday morning.

Ten international students have had their visas revoked by the U.S. Department of Homeland Security across Colorado universities. The University of Colorado released a statement confirming that F-1 visas issued to four international students on its Boulder and Colorado Springs campuses were revoked.

An immigration attorney told CPR News the students have the choice to either self-deport or stay and fight – but that leaves them open to being detained.
