The US State Department ordered diplomatic posts around the world to “resume processing” of Harvard University student and exchange visitor visas on Friday after a judge halted President Donald Trump’s latest attempt to block international students from coming to the institution.

The university called it “yet another illegal retaliatory step” from an administration that has sought ways to circumnavigate the courts in its push to bar foreign students.

President Donald Trump has escalated his standoff with Harvard University, seeking another path to prevent international students from attending the school after a judge blocked an attempt to revoke Harvard’s ability to enroll international students.
