Entering the United States
A visa allows a foreign citizen to travel to a U.S. port-of-entry (generally an airport) and request permission to enter the United States. A visa does not guarantee entry into the United States. The Department of Homeland Security (DHS), U.S. Customs and Border Protection (CBP) officials at the port-of-entry have authority to permit or deny admission to the United States. If you are allowed to enter the United States, the CBP official will provide an admission stamp or a paper Form I-94, Arrival/Departure Record. Learn more about admissions and entry requirements, restrictions about bringing food, agricultural products, and other restricted/prohibited goods, and more by reviewing the CBP website.
Extending Your Stay
See Extend Your Stay on the U.S. Citizenship and Immigration Services (USCIS) website to learn about requesting to extend your stay beyond the date indicated on your admission stamp or paper Form I-94.
You must depart the United States on or before the date indicated on your admission stamp or paper Form I-94, unless your request to extend your stay is approved by USCIS. Failure to depart the United States on time may also result in you being ineligible for visas you may apply for in the future. Review Visa Denials and Ineligibilities and Waivers: Laws to learn more.
Visitors are not permitted to accept employment or work in the United States.
We cannot guarantee that you will be issued a visa. Do not make final travel plans or buy tickets until you have a visa.
Unless canceled or revoked, a visa is valid until its expiration date. Therefore, a valid U.S. visa in an expired passport is still valid. If you have a valid visa in your expired passport, do not remove it from your expired passport. You may use your valid visa in your expired passport along with a new valid passport for travel and admission to the United States.
