Sacramento State is among the growing number of California colleges where international students have lost their visas amid a nationwide immigration crackdown.

The university confirmed Monday night that federal authorities revoked the visas of some within its student body. Multiple media outlets have reported this week that President Donald Trump’s administration has canceled international student visas at California campuses, including UC Davis, UCLA, UC Berkeley and Stanford.

The visas of 36 students in the California State University system were revoked as of Tuesday, said CSU spokesperson Amy Bentley-Smith in an email statement.

Sacramento State did not specify the number of its students affected, citing privacy. About 3% of students are international, according to recent university data.

“We understand that this news may cause distress and that it raises many questions for those impacted, as well as for their peers, colleagues, and mentors,” said Sacramento State President Luke Wood in a campus-wide email Monday night.

Twelve international students and recent graduates at UC Davis had their visas canceled, according to an April 5 news release. Chancellor Gary S. May said the federal government had not explained the reasons behind these terminations.

Federal immigration officers have not yet entered any California campus during Trump’s presidency. Roughly 14% of all international college students in the U.S study in California, according to data from the SEVIS Data Mapping Tool.

In his email statement, Wood encouraged students to reach out to the CSU’s free legal immigration services or International Programs & Global Engagement with questions or concerns.

He also recommended students and employees who are undocumented or with an immigrant status to urge caution when deciding to travel abroad.

“The contributions of our international community are invaluable,” Wood said. “We stand with those facing uncertainty and will continue advocating on their behalf at both institutional and national levels.”
