ROCHESTER, N.Y. — The University of Rochester and the Rochester Institute of Technology are among the colleges across the nation where some international students have had their visas revoked.

UR President Sarah Mangelsdorf said in a letter that five current students and six recent graduates had their visas revoked. RIT also released a statement saying that several students have been affected by visa changes but couldn’t give specifics.

Earlier this week, university officials at Harvard, Stanford, Michigan, UCLA, Ohio State, and others also learned that some of their students had lost their visa statuses. The AP reports that, while some students have seen their visas stripped for their connection to pro-Palestinian protests, it’s not the only reason. In some cases, past infractions such as traffic tickets have been cited, and other times, the reason is unclear to university officials.

According to the U of R, the visas were revoked without communicating with the university. The letter says the university is working to provide resources to students worried about their immigration statuses.

“We are deeply troubled by the escalation of immigration enforcement activity toward our international students,” Mangelsdorf wrote in the letter.

The U of R said that, out of the 11 people who lost their visa status, nine had their records terminated in the Student and Exchange Visitor Information System. That’s the Department of Homeland Security’s database on students studying in the U.S.

The university said its International Services Office is monitoring that database multiple times a day and will notify students if there’s a change to their visa status. From there, the university will help students to “evaluate their best enrollment and legal options.”

RIT also said it’s also monitoring the database several times a day and is working with impacted students to provide resources. Here is the full statement:

“RIT is committed to supporting our international students, who are essential to our academic community. While we cannot comment on individual student immigration matters due to privacy concerns, we can confirm that several of our students have been affected by recent visa changes. Our international student office proactively monitors the SEVIS database multiple times daily and works closely with those impacted to provide resources and support during this difficult time.”

“We will continue to monitor developments and advocate for policies that allow students worldwide to pursue their RIT education in the United States safely and without disruption.”

The U of R said it has resources on its website on what a campus community member should do if federal immigration enforcement contacts them. The university also said it’s continuing to monitor federal government policies.

“We want to reiterate that our university is deeply enriched and strengthened by our international students, faculty, and staff,” Mangelsdorf wrote. “We have a long legacy of welcoming students and scholars from all over the world, enrolling our first international students three years after our founding in 1850.”

News10NBC also reached out to other local colleges. Monroe Community College said none of its international students have had their visas revoked.
