As an F-1 or J-1 student or scholar, you may need to visit the Office of Global Services (OGS) for a new travel signature on your I-20 or DS-2019 before you leave the United States. If you need a Travel Signature, you have the option of taking your I-20/DS-2019 to the Office of Global Services (OGS) where it will be processed within five business days. Prior to major vacation periods, the OGS often offers travel signature sessions that require pre-registration. Upon successful screening, you will receive your travel signature on the spot. If you come to a session, please bring your I-20/DS-2019 form and your nine digit NU ID number. Visit the events page for the dates for travel signature sessions.
