The federal court hearing in Boston is in response to several attempts by the Trump administration to prevent Harvard from enrolling international students or allowing them to enter the country to study. The university began its second lawsuit against the federal government last month.

Harvard is seeking an order that would allow student visa holders to enter the country while the university weighs its legal battle against Trump’s directive.

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.
