A federal district judge ordered the Trump administration on Thursday not to make any changes to Harvard University’s student visa program.

Judge Allison Burroughs issued a preliminary injunction, saying she wants to “maintain the status quo” in allowing the school to resume accepting foreign students and visa holders. 

She instructed Harvard and the Trump administration to work out an agreement to temporarily stop the pause on Harvard’s student visa program. 

“It doesn’t need to be draconian, but I want to make sure it’s worded in such a way that nothing changes,” she said.

Ahead of the hearing on Thursday morning, the administration filed a legal notice that gives Harvard 30 days to argue its case to remain eligible for the Student and Exchange Visitor’s program, which enables schools and universities in the U.S. to host visa-carrying international students.

The Department of Homeland Security informed Harvard earlier this month that it would no longer be allowed to enroll foreign students due to “pro-terrorist conduct” on campus. The university responded by filing a lawsuit accusing the administration of pursuing a “campaign of retribution.”

Homeland Security Secretary Kristi Noem first demanded that Harvard provide information about the “criminality and misconduct” of foreign students on its campus on April 16. She warned at the time that refusal to comply would result in the termination of the university’s visa program.

International students make up 27 percent of Harvard’s total enrollment. If the Trump administration’s ban stands, Harvard President Alan Garber predicted the impacts would be devastating for the university.

It’s the latest update in a bitter battle between the administration and the Ivy League university; the administration had already frozen $3.2 billion in grants and contracts with Harvard and attempted to revoke Harvard University’s ability to enroll foreign students.

The administration has implemented increasingly escalatory tactics against the university since it rejected the administration’s demands to ban students “hostile to the American values,” to perform an audit of the political ideology of students and faculty to ensure “viewpoint diversity” and to offer quarterly status updates to the administration, among other things.
