A Chinese student has sued the government over revoking his visa without warning. He won his first battle, but the outcome remains uncertain.

It is not immediately clear why students’ visas were terminated. Some schools said the federal government had not notified them of their students’ change of status, but rather learned about it when reviewing records.

The university released few details, but the move comes amid the Trump administration's efforts to deport students involved in pro-Palestinian protests on college campuses.
