In a stunning blow to international scholars who had hopes of studying in the United States, the Trump administration has revoked hundreds of student visas in nearly every corner of the country as part of a vast immigration crackdown.

The speed and scope of the federal government's efforts to terminate the legal status of international students have stunned colleges and universities across the country.

Around 1,000 international students in the U.S. have had visas revoked or their legal status terminated since late March, according to an AP review.
