Travel and Visa Stamping
H-1B visa vs. H-1B status
An H-1B visa is a stamp issued in an individual’s passport by a U.S. embassy or consulate abroad which allows them to seek entry to the U.S. A visa stamp does not determine the period of stay in the U.S., meaning an individual’s visa can expire while in the U.S. without jeopardizing their ability to remain in the U.S.
H-1B status is granted by Customs and Border Protection (CBP) upon entry to the U.S. or by United States Citizenship and Immigration Services (USCIS) with an I-797 Approval Notice. An I-94 – issued by either CBP or USCIS – determines the period of stay in H-1B status, meaning an H-1B employee may not work or otherwise remain in the U.S. beyond the I-94 end date, unless the employee has a pending H-1B petition.
For more information on period of stay and I-94, see Period of Stay & I-94.
Travel
Travel to/ from U.S. states and territories does not require a visa stamp but air travel does require a Real ID.
International Travel
International travel should be carefully considered based on the purpose and necessity of the trip as entry restrictions and other risk factors may exist. ISSS has created an International Travel Worksheet for individuals to make informed decisions on international travel, prompting them to evaluate their travel plans by confirming the trip’s necessity, assessing admissibility risks, reviewing applicable U.S. entry requirements, ensuring documents remain valid, and gathering supporting materials.
For more information on international travel considerations, see [“ISSS Update on Spring and Summer 2026 International Travel Considerations” or “ISSS Immigration Updates”]
Automatic Revalidation
International travel generally requires a valid visa stamp in a valid for an individual to request reentry to the U.S. However, under automatic revalidation, individuals holding expired visas who request reentry to the U.S. may be admitted by CBP if:
- be in valid H-1B status and reenter to resume the same status;
- have a valid Form I-94 Arrival Record showing J status and D/S (duration of status);
- travel only to Canada or Mexico for 30 days or less;
- do not apply for a U.S. visa while abroad;
- is not a national of a State Sponsor of Terrorism designated country. Review more about State Sponsors of Terrorism and FAQs on this website;
- has never had a visa cancelled for visa overstay;
- is otherwise admissible.
Obtaining a visa stamp
A visa stamp is obtained at a U.S. embassy or consulate in an individual’s country of residence. If routine U.S. visa operations are suspended or paused in an individual’s country of residence, they should apply at their designated immigrant visa processing post, unless the individual is a national of another country with ongoing operations.
Note that the time needed to obtain a visa stamp varies depending on the country and U.S. embassy or consulate. For current visa wait times, see Department of State Visa Appointment Wait Times.
The documents needed to obtain a new visa stamp at a U.S. embassy or consulate include:
- I-797 Approval Notice
