On Aug. 18, the U.S. State Department revoked about 6,000 student visas. Some of the visas were revoked due to alleged criminal activity, such as assault, burglary, driving under the influence, etc. Many cases simply involved overstaying visas, but 200 or 300 visas were revoked due to “support for terrorism,” which means, in most cases, that the person was involved in legally protected anti-genocide protests on a university campus. However, it appears that none of these 6,000 students has ever been convicted of any crime, according to the Washington Post. Previous efforts by the Trump administration to block universities from enrolling foreign students were barred by federal court order.
