You may leave the United States and return at any time during your program, provided you are still in valid immigration status when you return and you have been absent from the country for less than five months. With the exception of travel to Canada or Mexico and adjacent islands, you must present an unexpired U.S. visa to request entry back into the country. When re-entering the United States after traveling abroad, you must present the following at the Port of Entry:
* If you are traveling to Canada, Mexico, or certain contiguous territories for less than 30 days, and you are not a foreign national of certain countries designated by the Department of State, you may be permitted to re-enter the United States with an expired visa. For more information, review the Automatic Revalidation of Visa Validity section.
Your I-20 or DS-2019 must have an unexpired travel signature in order for you to request re-entry into the United States. The travel signature is valid for one year from the signature date, unless you are on F-1 Optional Practical Training, in which case it is valid for six months. We recommend requesting a new travel signature every nine months, even if you do not plan on traveling.
To help determine if you need a travel signature, you can use this chart as a guide. Please visit our office if you still have any questions.
We ask that you obtain a travel signature by bringing your I-20 or DS-2019 to the International House during walk-in hours. Only under special arrangements with ISSS may you leave it to be signed and picked up later. Please send a request to firstname.lastname@example.org if you are unable to come in person during walk-in hours for the signature.
