ST. LOUIS — As the Trump administration continues to crack down on international students across the country, over 25 students in the St. Louis region had their visas revoked in April.

Over 900 students at more than 128 colleges and universities have had their visas revoked or legal status terminated with little to no notice throughout recent weeks, according to the Associated Press.

Webster University reports that 18 international students enrolled on campus had their visas revoked recently, including six other students at their San Antonio, Texas campus.

“We are working closely with these students and also trying to get further information from SEVP (Student Exchange Visitor Information System) regarding next steps,” the school said in a statement to FOX 2. “Some of these students have also contacted immigration attorneys for assistance.”

Southern Illinois University Edwardsville also became aware that beginning April 4, the student visas had been revoked of three undergraduates and six former graduates enrolled in their optional practical training program.

“SIUE is devoting resources to supporting our international students as much as the law allows,” a statement to FOX 2 said. “Whenever an international student has legal issues regarding immigration, we advise them to consult with an immigration attorney to represent their particular case.”

SIUE told FOX 2 the school sent a message to students advising them to keep photocopies of their immigration documents on them at all times, including proof of their enrollment at SIUE. Additional resources were recommended to international students, including counseling and basic needs support.

Across Missouri, Northwest Missouri State University reported 43 students had their visas revoked so far. Missouri State University in Springfield also reported six international students whose SEVIS records and F-1 student statuses were terminated by the Department of Homeland Security without warning.

The Associated Press reports that around 1.1 million international students were in the U.S. last year, becoming an essential revenue source for tuition-driven colleges and universities. Often international students pay full price for tuition as they are not eligible for federal financial aid.
