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 paper Form I-94, Arrival/Departure Record. Learn more on the CBP webpage.
Learn more about procedures for students (with F or M visas) entering the United States on the CBP website under Arrival Procedures for Students or Exchange Visitors. Review admissions requirements, as well as restrictions about bringing food, agricultural products, and other restricted/prohibited goods, by reviewing the CBP website under International Visitors and Clearing CBP.
Students with F visas have an additional 60 days after the program end date listed on Form I-20, and any authorized practical training, to depart the United States.
