A port of entry is any place where you can officially enter the United States — airports, land border crossings, and seaports. It's where Customs and Border Protection (CBP) officers inspect you, check your documents, and decide whether to admit you.
Having a valid visa doesn't guarantee entry. The CBP officer at the port of entry has the final say. They can ask you questions, request additional documents, and in some cases, deny you entry altogether — even with an approved visa in your passport.
Your port of entry experience creates your I-94 record — the document that determines how long you can stay. The CBP officer decides your admission class and authorized stay period right there at the border. Getting this right matters for everything that follows.
- A visa gets you to the door — the CBP officer at the port of entry decides if you walk through it
- Bring all supporting documents (approval notices, financial proof, itinerary) in your carry-on, not checked luggage
- Answer questions honestly and briefly — don't volunteer extra information
- If you're sent to secondary inspection, don't panic — it happens and doesn't mean you're being denied
- Check your I-94 online after entry to make sure the dates and admission class are correct
