Please notify OIS of your international travel plans. In order to return to the U.S. after traveling abroad, you will need a valid visa stamp in your passport (unless you are visa stamp exempt). If you do not have one, you will have to apply for an appropriate visa at a U.S. Consulate abroad. There can be wait times for visa appointments; before you depart the U.S., visit the website of the consulate you will use to learn about application procedures and processing times.
Carefully check your I-94 arrival/departure record every time you enter the United States. Your I-94 defines your period of lawful stay in the United States. If the end date on your electronic I-94 is different from the end date on your I-797 approval notice, the date on the I-94 prevails.
Send OIS copies of any new visa stamps and every I-94 record when you re-enter the U.S. following international travel.
Documents you will be required to present at the U.S. point of entry include:
- Passport valid for at least six months beyond your period of authorized stay in the U.S. If your passport expires before the end date on your I-797 approval notice, Customs and Border Protection will limit your I-94 to the expiration date for your passport.
- Valid original I-797 notice of approval for H-1B or O-1 employment
- Valid visa stamp*
- Copies of your three most recent pay stubs (recommended)
- Employment verification letter (recommended)
* Canadian citizens do not need a visa.
