In the lawsuit filed early Friday in federal court in Boston, the Ivy League school called out the government’s ban as a violation of the Constitution and warned that it would have an “immediate and devastating effect for Harvard and more than 7,000 visa holders.”

The latest confrontation between Harvard University and the Trump administration began last month with a far-reaching demand for data on international students.

"It would be devastating," a former president of Harvard — and frequent critic of the university — said of the government's attempt to prevent Harvard from enrolling foreign students.

Some of Harvard’s sports teams would be virtually wiped out by a Trump administration decision that would make the Ivy League school ineligible for international student visas.

If Trump succeeds in crushing Harvard, all other American institutions of learning, science and humanities will be at risk,' writes an L.A. Times reader.

Harvard University international students are scrambling to figure out whether they will soon be forced to transfer.

The Trump administration intensified its battle with Harvard University on Thursday, revoking the storied college’s ability to enroll foreign students and demanding that any such current students transfer elsewhere for the next academic year or lose their visas.
