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.

The Trump administration said current foreign students must transfer or risk losing their legal status. Advocates say the directive violates legal procedures.
