An F1 student can legally remain in the U.S. with an expired visa as long as your I-20 has not expired and you are fully registered for coursework. However, students cannot reenter the U.S. with an expired F1 visa except in certain limited circumstances only involving short travel to Canada or Mexico.
To renew your F1 visa, you need to follow the same requirements as a student who is applying for an F1 visa for the first time. We recommend that you prepare the following documents:
The application instructions and required documentation may vary by U.S. Embassy or Consulate. Please consult the instructions on the US Embassy or Consulate website to learn about the specific requirements to apply for a student visa in your country. Although we encourage students to apply for a visa in their home country, we advise you to keep open the possibility of travelling to another nearby country’s embassy or consulate if you are unable to travel to or apply in your own country.
