# International Student Services The Office of International Personnel together with the Graduate School of Biomedical Sciences co-ordinate services for international students who have been accepted to one of the School’s residential graduate programs. The F-1 student visa for Icahn School of Medicine at Mount Sinai’s international students is sponsored by ISMMS. All international students must register with the Office of International Personnel within 15 days of matriculation at ISMMS and must notify this Office of any changes in their academic program, enrollment status or if they plan to leave the country to preserve their visa status. Students must show proof of a valid I-20 before the fellowship package can be activated. It is the student’s responsibility to make sure that s/he is always in status, as mandated by the United States Homeland Security. All visa questions should be addressed to the Office of International Personnel at (212) 241-8300. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
