You should keep your passport valid at all times. Your passport is your own government’s permit for you to leave and re-enter your own country. Most passports contain an expiration date. Consult your own consulate or embassy in the U.S. to renew your passport.
F-1 Visa Renewal
International students in the U.S. are generally admitted under the F-1 student visa classification. Under special circumstances, international students may also be admitted on J-1 sponsored student visa. Those who petition for F-1 or J-1 visas are admitted as a non-immigrants, and are granted temporary stays in the U.S. In order to apply for the F-1 visa, the prospective student must receive a SEVIS I-20.
Your F-1 visa needs to be valid for entry to the U.S. but can expire during your enrollment at UL Lafayette if you stay in the U.S. If you are studying full-time at UL Lafayette with a valid F-1 status, you do NOT need to renew your F-1 visa while you are in the U.S. You only need to renew your F-1 visa if you plan to travel outside of the U.S. and return to the U.S. to study. If your F-1 visa expires before you travel outside of the U.S., you will need to apply for a new visa to re-enter the U.S. We strongly recommend that you renew your F-1 visa before completing your degree program as it will be very difficult to apply for a student visa once you have completed your program. Please note that F-1 visas cannot be renewed from within the U.S.
