Alert

On July 17, 2026, the U.S. Department of Homeland Security published a final rule that establishes a fixed time period of admission and an extension of stay procedure that impact students and scholars on F-1 and J-1 visas. The rule is anticipated to take effect Sept. 15, 2026. While Northwestern analyzes this complex rule, we are working to update our website and communicate guidance as quickly as possible. Members of the Northwestern international community who have questions are encouraged to reach out directly to their assigned OISS advisor.
