What documents do I need to enter Puerto Rico?
Puerto Rico is a US territory, so US citizens fly there without a passport. Everyone else needs the same US visa or ESTA they would need for the mainland.

Entering Puerto Rico - what you need
The confusion behind this question is that Puerto Rico feels like a foreign country and legally is not one. It is an unincorporated US territory, and US immigration and customs law applies there in full. Your answer depends entirely on your citizenship, so pick the section below that matches you, and keep your trip1 booking confirmation to hand for check-in either way.
If you are a US citizen
You do not need a passport to fly from the mainland to San Juan. You need the same photo ID any domestic flight requires, and since 7 May 2025 that means a REAL ID compliant driver's licence with the star marking, or another accepted document such as a US passport or passport card.
Children under 18 flying with an adult usually do not need ID for a domestic flight, though the airline can set its own rules for unaccompanied minors. A passport is still worth packing if your trip continues to another Caribbean island, because that leg is international.
If you are a US permanent resident
Carry your green card, which is both your ID for the flight and the document you are required to have on you. No visa or ESTA is involved.
If you are not a US citizen
Treat a trip to Puerto Rico as a trip to the United States, because that is what it is. Flying in from abroad you clear US Customs and Border Protection at Luis Munoz Marin International Airport in San Juan, the same as you would in Miami or New York.
- A passport valid for your stay. Many nationalities are asked for six months of validity beyond departure, unless your country is on the US six month club list.
- An approved ESTA if you hold a passport from a Visa Waiver Program country, which covers stays of up to 90 days.
- A US visa, usually a B-2 visitor visa, if your nationality is not in the Visa Waiver Program or your trip does not qualify for it.
- A return or onward ticket and an address for your stay, which officers ask for routinely. Your trip1 confirmation answers the accommodation question in one screen.
Important: Apply for your ESTA on the official US government site well before departure, not at the airport. Airlines check the approval before boarding, and there is no way to fix a missing one on arrival in San Juan.
Flying from the US mainland on a visa or ESTA
If you were already admitted to the United States, a hop to San Juan is a domestic flight and there is no second immigration check. Bring your passport anyway, since it is the ID that always works at the gate and at a hotel desk.
One thing to watch: the trip does not reset anything. Your admission period on the I-94 or the 90 days of an ESTA keeps running while you are on the island, because you never left the country.
Going home from Puerto Rico
There is no customs or passport control on flights back to the mainland. What you do get is a USDA agricultural inspection of your bags before departure, so leave behind fresh fruit, plants, soil and pork products picked up on the island.
Hotel check-in in Puerto Rico
Hotels ask for one government-issued photo ID for the person named on the booking, plus your reservation reference. A driver's licence is fine for US guests and a passport is the safe option for everyone else.
Many Puerto Rico hotels also ask for a card at check-in to hold a deposit for incidentals such as the minibar or resort charges. That is the hotel's own policy and separate from how you paid for the room on trip1.
Entering Puerto Rico - FAQ
Not if you are a US citizen flying from the mainland, because Puerto Rico is a US territory and the flight is domestic. You still need a TSA-acceptable photo ID, which since 7 May 2025 means a REAL ID compliant licence or another accepted document such as a passport.
If you need a visa for the United States, you need the same visa for Puerto Rico. US immigration law applies there in full, so there is no separate Puerto Rico visa and no visa on arrival.
Yes, if you are travelling under the Visa Waiver Program and flying in from outside the United States. Apply on the official ESTA site before you book flights, because airlines will not board you without an approved authorisation.
Yes. There is no passport control in either direction, so a foreign visitor already admitted to the United States does not get a new admission or a new 90 day clock by flying to San Juan.
No customs or immigration check on flights back to the mainland, but your bags go through a USDA agricultural inspection before departure. Certain fruit, plants and pork products cannot leave the island.
