COLUMBUS, Ohio — The Ohio State University President Walter “Ted” Carter Jr. released a message to students, faculty and staff after at least seven students recently lost their F-1 visas.

Carter says the university was not formally notified of the federal government’s actions. The university was also not told why the students’ visas were revoked.

An F-1 visa is what students who wish to travel to the United States to study must obtain.

Carter says the university has been in contact with the seven students to offer resources and support.

While the university doesn’t have a role in these decisions, Carter says he wants clarity on what’s happening.

“Ohio State, after all, has long been – and will continue to be – proud to welcome students from all over the world, who add greatly to the life of our campuses and community. International students, visiting scholars and staff enrich the Ohio State experience for all, and we are a stronger university for their presence and contributions,” Carter said.

The loss of the students’ visas comes as the Trump administration is cracking down on foreign students.

Many college officials worry the new approach will keep foreigners from wanting to study in the U.S.

Students stripped of their entry visas are receiving orders from the Department of Homeland Security to leave the country immediately — a break from past practice that often permitted them to stay and complete their studies.

Some students have been targeted over pro-Palestinian activism or criminal infractions — or even traffic violations. Others have been left wondering how they ran afoul of the government.
