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, and other academic restrictions specifically for F-1 students. The rule is anticipated to take effect Sept. 15, 2026 and will affect members of the international community in different ways. As OISS gathers more information and communicates specific guidance to individuals and groups, we ask that members of the international community refer to the DHS Rule on Admission and Extension webpage as an up-to-date resource. Members of the Northwestern international community who have questions are encouraged to reach out directly to their assigned OISS advisor.
