US President Donald Trump’s administration revoked Harvard University’s ability to enroll international students on Thursday, and is forcing current foreign students to transfer to other schools or lose their legal status, while also threatening to expand the crackdown to other colleges, Reuters reported.

Homeland Security Secretary Kristi Noem ordered the department to terminate Harvard University’s Student and Exchange Visitor Program certification effective for the 2025-2026 school year, the department said in a statement.

Noem accused the university of “fostering violence, antisemitism, and coordinating with the Chinese Communist Party.”

Harvard said the move by the Trump administration - which affects thousands of students - was illegal and amounted to retaliation, according to Reuters.
