Do you need a passport for St. Thomas or St. John?

Why St. Thomas needs no passport

The US Virgin Islands are a US territory, and US Customs and Border Protection says plainly that a citizen arriving from one is not treated as having left the country. A flight from Miami or San Juan to St. Thomas is domestic, and USA.gov lists the US Virgin Islands among the territories a citizen travels to without a passport, as of its March 2026 update.

The exception is the route. CBP says a traveler who also visited a place outside the United States must present a passport, so a trip that takes in Tortola, or connects through a foreign airport, needs one.

Which ID the TSA accepts for the flight

Every adult needs an ID the Transportation Security Administration (TSA) accepts, and a driver's license counts only if it is REAL ID compliant, which the TSA has enforced since May 7, 2025.

The TSA accepts these up to two years past their expiry date. Without any of them, the TSA's ConfirmID check costs $45 as of February 1, 2026, and the agency asks you to pay it before you leave for the airport.

What children need to fly to St. Thomas

Nothing, as far as the TSA is concerned: it does not require children under 18 to show identification on a flight within the United States, as of October 2026.

The rule changes at the BVI border: the Government of the Virgin Islands' immigration bulletin of March 2025 asks every visitor who is not a BVIslander or Belonger for a valid passport book or US passport card, so a family day trip to Jost Van Dyke means one for the baby too.

The CBP check on the flight home

Flying back to the mainland is the one step that feels international: US Customs and Border Protection runs predeparture processing at Cyril E. King Airport on St. Thomas and Henry E. Rohlsen Airport on St. Croix, before the gate, checking that each traveler meets the mainland's entry requirements; Mobile Passport Control lanes opened there in May 2026.

A citizen is not required to show a passport there, but CBP recommends having evidence of citizenship to hand: a passport, a birth certificate or a Trusted Traveler card. The tradeoff: the line sits between you and the gate, so it belongs in the time you leave for the airport.

What you can bring home duty-free

$1,600 a person, double the usual allowance, because CBP treats the US Virgin Islands as an insular possession. The rules on its Types of Exemptions page, last modified March 2024:

The made-there condition is the one a shopper misses: of the five liters, at least one must be a product of the US Virgin Islands. Your home state's limit on personal quantities still applies, per CBP.

Entry rules for visitors who are not US citizens

A visitor who is not a US citizen needs a passport and the US visa or ESTA their nationality requires, as of October 2026; check which applies with US Customs and Border Protection before you book. A green-card holder shows the permanent resident card, which the TSA lists among its accepted IDs and CBP names at its predeparture lanes in its May 2026 release. Anyone coming back from Tortola by ferry should carry a passport or another approved document to re-enter the United States by sea, the BVI Tourist Board advises as of October 2026.

Do you need a passport for the British Virgin Islands?

Yes. Tortola, Jost Van Dyke and Virgin Gorda are British, and the BVI Tourist Board says that anyone arriving by air or sea must present a passport to enter and to depart, as of October 2026. A US passport card does both jobs: the Government of the Virgin Islands' immigration bulletin of March 20, 2025, in force from March 1, 2025, accepts a valid passport book or a passport card from US citizens, and CBP accepts the card for coming home by sea.

The paper landing card was retired on January 1, 2025, per the BVI Tourist Board. Each traveler fills in the online immigration and customs form, from 36 hours before arrival or at the terminal once the ferry ticket is bought, with a photo of the passport's photo page. The BVI Tourist Board lists hours for the ferry ports of entry, as of October 2026: Road Town 8:30 am to 8 pm daily, Great Harbour on Jost Van Dyke 8:30 am to 4:30 pm daily, and West End 8:30 am to 4:30 pm Monday to Thursday, to 6 pm Friday to Sunday. Coming back, the BVI Tourist Board reminds US citizens that re-entering the United States by sea may take a passport or another approved document.

Questions people ask

Do you need a passport to go to St. Thomas?

Not if you are a US citizen flying from the mainland or Puerto Rico. US Customs and Border Protection treats St. Thomas as part of the United States, so the flight is domestic and an ID the TSA accepts is enough, as of October 2026. You do need a passport if the trip includes the British Virgin Islands or a foreign connection.

Do you need a passport for the US Virgin Islands?

No, for US citizens: USA.gov lists the US Virgin Islands among the territories a citizen visits without one, as of March 2026. That covers St. Thomas, St. John and St. Croix. A visitor who is not a US citizen needs a passport and the US visa or ESTA their nationality requires.

Do you need a passport for the Virgin Islands?

It depends which. The US Virgin Islands need no passport for a US citizen. The British Virgin Islands, Tortola, Jost Van Dyke and Virgin Gorda, need a valid passport book or US passport card for every US traveler, children included, per the Government of the Virgin Islands' immigration bulletin of March 2025 and the BVI Tourist Board as of October 2026. A ferry day trip from St. Thomas crosses that line.

What do you declare coming home from the US Virgin Islands?

Goods worth $1,600 a person, per CBP, including up to five liters of alcohol, as long as four were bought in the territory and one was made there. Extra bottles pay a flat 1.5% duty plus IRS taxes. Gifts mailed home are duty-free up to $200, and alcohol and tobacco cannot be mailed that way.
