A federal judge has blocked a Trump administration decision to revoke Harvard University’s ability to enroll international students.

BRUSSELS (AP) — Belgium’s Royal Palace said Friday that Princess Elisabeth, who is first in line to the throne, is waiting to find out whether she can return to Harvard for her second year after U.S. President Donald Trump announced a ban on foreign students at the university.

A judge has issued a temporary restraining order blocking the Trump administration's plan to strip Harvard University of its ability to enrol foreign students. The ruling came after Harvard filed a lawsuit - the latest escalation of a dispute between the White House and one of America's most prestigious institutions.
