Port of entry overview
#Admission to the United States is decided at the port of entry by CBP officers. Having a visa or ESTA does not guarantee entry.
The officer’s decision is based on your documents, answers, and purpose of travel. Clear and consistent information helps reduce delays.
What to bring
#Passport and travel authorization. Bring your valid passport and your visa or ESTA documentation.
Purpose evidence. Carry documents that support your purpose, such as an invitation, admission letter, or itinerary.
Proof of onward travel. If applicable, have evidence of return or onward travel to match your stated plans.
Examples
#Example: A student arrives with a valid visa, I-20, and school contact details to confirm the program and start date.
Example: A visitor arrives with a short itinerary and return ticket that matches the stated length of stay.
