The Trump administration threatened on Wednesday to withdraw Harvard University from the federal program that administers student visas if it does not comply with a records request by the end of the month.

The Trump administration has significantly dialed up its pressure on Harvard University, not only freezing $2 billion in federal funding but now threatening its eligibility to host international students after school leaders refused to make key policy changes the White House also is demanding of other elite US colleges.

The Trump administration is threatening to pull Harvard University’s Student and Exchange Visitor Program certification if it does not give the federal government information about students in the country on visas.
