PORTLAND, Ore. (KOIN) – At least 13 students attending Oregon State University are at risk of deportation after having their visas revoked by the Trump Administration, the university confirmed to KOIN 6 News on Thursday.

The recent initiative, led by the U.S. Department of Homeland Security, has impacted international students throughout the country as federal officials update — and even terminate — their immigration records. 

“While immigration records are terminated from time to time for different reasons, the suddenness of these federal agency-initiated actions nationally has led us to review student immigration records even more frequently so that we can provide support to those impacted,” OSU said in a statement to KOIN 6 on Thursday.

The announcement comes the same week the University of Oregon announced that four of their students had visas revoked due to alleged “criminal charges,” though the university said it was not given details about the charges by DHS.

Reasoning for the status changes impacting students at OSU remains unclear, though the university claims that these changes are rare. The state school currently has more than 2,500 international students.

“International students and employees who otherwise maintain their immigration status are typically not at risk of having their immigration status terminated suddenly, arbitrarily or without notification,” according to the university. “For decades, OSU has proudly sponsored thousands of aspiring students and scholars across many fields as part of our commitment to expanding pathways to higher education for students locally and globally.”

OSU officials say their Office of International Services has reached out to impacted students with resources to help them take next steps. Students or families who are concerned about their F-1 Visa status are encouraged to contact the office.

In response to these developments, OSU has joined other universities in filing support for a lawsuit brought forth by the American Association of University Professors challenging the actions “impacting international students and educators, including their speech and expression activities.”

Students typically have 15 days to leave the country unless they find another legal pathway to stay in the U.S.
