Typically, if a visa status is revoked, a student can complete their studies in the United States, but they cannot leave and re-enter the country. However, if students have their legal residency status removed, such as in the case of Khalil and Öztürk, they must leave the country immediately or risk being detained.

Federal immigration officials are rescinding the legal status of some international students, using rarely invoked powers.

Hundreds of student visas have been revoked across the United States, including almost 80 in North Texas. This comes as the Trump Administration announced new social media screenings for antisemitic activity by students seeking visas and those in the higher education system.

We are not aware of the details of the revocations or the reasons for them, but we understand these actions continue to take place at other institutions across the country," Harvard said in a post Thursday.

The university was not notified and only learned of the changes by proactively checking a government database.

The recent graduates whose visas were revoked were on post-completion OPT status, according to university officials, which allows them to work in the US for up to one year after they graduate.
