At least 70 students attending New York universities and colleges have had their student visas revoked by the Trump administration, according to several school officials.

Several universities across the country have confirmed to UPI that international students have had their visas revoked without notice or had their Student and Exchange Visitor Information System records terminated.

The university’s Office of International Services website says it has taken steps to inform students of the revocations and is providing “a range of support services.”
