Carry your documents with you in case you need to show evidence of your legal immigration status.
Troubleshooting Potential Problems
Your U.S. visa has expired or will expire before your return
Generally, you need an unexpired U.S. visa to return to the U.S.with two exceptions:
- Canadians are exempt from the visa requirement (but do require an I-20/DS-2019).
- When you return return to the U.S. from Canada, Mexico, or an "Adjacent Island" you may be eligible for "automatic revalidation". Visit this webpage to learn about these special provisions.
U.S. visas cannot be obtained here in the United States. You can apply for a new visa only at an U.S.consulate or embassy abroad, so be mindful of visa application procedures and the time needed for visa processing when you make your travel plans.
You're already abroad and
you don't have your I-20/DS-2019 with you, or
your travel signature has expired or will expire before your return
Your new form will have an updated travel signature on it. Follow the instructions on our Travel Signatures webpage.
Refer to "Returning to the U.S. Without all Required Documents" on our Travel Signatures webpage.
