U.S. District Judge Allison Burroughs in Boston extended a temporary restraining order on Trump’s proclamation until June 23 while she weighs Harvard’s request for a preliminary injunction. Burroughs made the decision at a hearing over Harvard’s request, which Trump’s Republican administration opposed.

Lawyers for Harvard had urged the court to to block Trump's efforts to revoke its credentials to host foreign students, and block foreign students from traveling to the US to study at the university.

A federal judge said on Monday that she would issue a brief extension of an order temporarily blocking President Donald Trump's plan to bar foreign nationals from entering the U.S. to study at Harvard University while she decides whether to issue a longer-term injunction.
