On June 4, 2025, President Donald Trump signed a proclamation suspending the entry of international students intending to study at Harvard University for six months.
The administration cited national security concerns, alleging that Harvard failed to comply with federal regulations and had ties to foreign entities. The order affects new applicants under F-1, M-1, and J-1 visa categories and directs the State Department to consider revoking existing visas of current international students at Harvard. Harvard condemned the action as unconstitutional and retaliatory, vowing to protect its international student community.
