The State Department has revoked 6,000 student visas so far this year, Fox News reported along with The Washington Post.

Of that group, 4,000 were revoked due to crimes, including assault, driving under the influence and burglary. However, a department spokesperson told the Post that the students whose visas had been revoked “either faced arrest or charges,” but the spokesperson didn’t specify whether they were convicted.

The spokesperson also said that between 200 and 300 visas were revoked due to “support for terrorism.” President Donald Trump has previously labeled pro-Palestinian student protesters as terrorist sympathizers and has targeted international students over their pro-Palestinian activism.

The Post article does not address whether these students will have to stop their studies and leave the U.S. A visa—the stamp that permits an individual to enter the U.S.—is different from one’s nonimmigrant status, which refers to whether they are lawfully in the country, something immigration experts stressed amid a slew of student visa revocations in March and April.
