In May, the Trump administration announced it was immediately revoking Harvard’s ability to enroll foreign students, and ordered those already attending the school to either transfer or leave the country.

A federal judge has sided twice with Harvard University, approving two preliminary injunctions to protect Harvard international students.

The Trump administration is challenging a judge's ruling. This ruling blocked a proclamation affecting Harvard's international students. The appeal continues a legal battle that began in May. The proclamation cited concerns about Harvard's foreign ties.
