The Trump administration revoked Harvard University's ability to enrol international students on Thursday. Current students will be forced to transfer to other schools or lose legal status, the U.S. Department of Homeland Security said.

Harvard sued and asked for a restraining order less than 24 hours after the Trump administration had said it would block current and future international students from attending the university.
