The Trump administration’s now-paused revocation of Harvard University’s ability to enroll international students raises significant questions about how a ban would impact the school community and its academic research.

The Trump administration is trying to strip Harvard of its ability to enroll international students — an effort blocked by a federal judge on Friday, just hours after the university filed a lawsuit claiming Trump was violating its First Amendment rights.

Harvard sued the Trump administration Friday morning and plans to file a temporary restraining order shortly to stop the Department of Homeland Security from revoking its certification to enroll international students.
