The Trump administration is overhauling rules governing the length of stay for international students and exchange visitors, replacing a decades-old system with a fixed period of up to four years.

Beginning Sept. 15, most people entering on F-1 and J-1 visas will no longer be admitted for “duration of status,” which generally allows them to remain in the country as long as they maintain their academic or exchange programs.

Instead, students and scholars will receive predetermined admission periods based on the length of their programs, capped at four years. Any extension needed to complete a degree, including for many doctoral candidates, will require an application to U.S. Citizenship and Immigration Services.

The new four-year visa cap could be damning for some colleges and universities that rely heavily on international students.

A new report from local outlet The Baltimore Banner warns that the University of Maryland “could face a decline of as much as 30% of its newly admitted graduate students this fall, thanks to a new visa restriction proposed by the Trump administration this summer.”

University officials disclosed a new estimate in court filings supporting a federal lawsuit seeking to block the four-year visa cap. The University of Maryland and University of Baltimore face similar contractions in international enrollment. 

According to the report, international students contributed an estimated $240.4 million to the University of Maryland and the surrounding economy during the 2024-25 academic year. At the University of Maryland, Baltimore, that figure was around $14 million.

Whether the four-year visa cap proves to be the final pin that finally punctures America’s higher-education bubble remains to be seen. But certaintly may cause hardships for universities that heavily rely on foreign enrollment.
