If your U.S. visa stamp in your passport has expired and you travel outside the U.S., you must obtain a new visa before you return (with the exception of those eligible to use Automatic Revalidation). It is not possible to renew a visa stamp from inside the United States. Applying for a new U.S. visa stamp usually requires several weeks so you must plan your travel accordingly. Certain visa applicants may be subject to further screening or Administrative Processing which can add 4-12 additional weeks to complete the visa application review and issuance. If you have questions about administrative processing or if you are experiencing a lengthy delay please contact International Programs.
Applying for a visa in a third country
Most international visitors will be able to apply for a new U.S. visa in a country that is not their home country. However there are exceptions. Before making your travel arrangements, carefully review the guidelines on the web site of the U.S. Embassy to which you will submit your application. This is particularly important if you have been subject to administrative processing during previous visa applications.
If you plan to visit Canada or Mexico to apply for a U.S. visa stamp, it is particularly important that you check the website of the U.S. consulate to which you will submit your application. You will find instructions about how to make the visa appointment. If you are an individual who has been subject to administrative processing during past visa appointments, you will want to think carefully before applying for a U.S. visa in a third country. Once a U.S. visa application is submitted you cannot use the Automatic Revalidation provision to return to the U.S.
