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.

While not all the affected schools said immigration status changes were tied to activism, they come as the Trump administration cracks down on students who protested Israel’s war in Gaza.
