Dozens of schools, including the University of California and Harvard, said the Trump administration ended the visas of their students in recent days. For many, the reasons are unclear.

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.

According to USA TODAY, there is no central accounting of how many students have had their visas revoked or where they came from, but some of the visa cancellations appear to be for varying reasons like roommate disputes, off-campus traffic tickets or pro-Palestinian protest participation.
