Focus phrase: Do I need a visa to transit through the USA from the UK.

If you are travelling from the UK and your journey includes a layover in the United States, you may need a visa or travel authorization depending on your nationality, destination, and whether you plan to leave the airport during your connection. This article explains when a visa is required, how the Visa Waiver Program (VWP) works, and what conditions apply under current U.S. immigration rules (October 2025).

Do I Need a Transit Visa to Travel Through the USA?

British citizens and most EU nationals do not need a visa to transit through the United States, provided they remain airside and do not exit the international transit area. However, if you plan to pass through U.S. border control, even briefly, you must obtain an Electronic System for Travel Authorization (ESTA) or a U.S. transit visa.

The U.S. Transit (C) Visa is typically required for travellers from countries that are not part of the Visa Waiver Program. It allows entry solely for the purpose of connecting flights or onward travel. For UK citizens, the Visa Waiver Program (VWP) is usually the preferred and faster option.

The U.S. Visa Waiver Program (VWP)

The Visa Waiver Program allows nationals from participating countries, including the United Kingdom, to enter the USA for up to 90 days for tourism, business, or short transit without applying for a visa. To use this route, travellers must apply online for an ESTA prior to travel.

To qualify, you must:

• Hold a valid biometric passport from a Visa Waiver Program country.
• Have an approved ESTA before departure.
• Hold a confirmed onward ticket to a destination outside the United States.
• Ensure your passport is valid for at least six months beyond your travel date.

Remember that the Visa Waiver Program only applies for short-term visits or transit. If you plan to work, study, or stay longer than 90 days, you will need to apply for a suitable U.S. visa.

Who Needs a U.S. Transit Visa?

You will need a U.S. Transit (C) Visa if:

• You are not a citizen of a Visa Waiver Program country.
• You have been previously denied entry or overstayed in the USA.
• You plan to leave the airport or stay overnight during your layover.
• Your ESTA application has been refused.

The Transit Visa allows a maximum stay of 29 days and does not permit sightseeing or other non-transit activities.

How to Apply for an ESTA or U.S. Transit Visa

To apply for an ESTA, complete the application at esta.cbp.dhs.gov. Approval typically takes minutes but can take up to 72 hours. The ESTA is valid for two years (or until your passport expires) and can be used for multiple entries, including short transits.

If you are not eligible for ESTA, apply for a U.S. Transit (C) Visa through the nearest U.S. embassy or consulate. You will need:

• A valid passport
• Proof of onward travel
• Visa for your destination country (if required)
• Payment of the visa fee

For related guidance, see: UK Visa Application Processing Centres 2025 (for biometric procedures and document preparation).

Conditions for Using the Visa Waiver Program

Before travelling under the Visa Waiver Program, ensure you:

• Have an ESTA authorization before boarding your flight.
• Do not have a criminal record or previous U.S. visa violations.
• Are not a national of a country restricted under the program (e.g. Iran, Iraq, Syria, North Korea).

If you fail to meet any of these requirements, you will need to apply for a standard transit visa instead.

Transit via the USA from the UK – Key Points

• British nationals do not need a visa if remaining airside during a U.S. layover.
• ESTA authorization is required if you enter the U.S., even briefly.
• ESTA holders can transit, visit, or attend short business meetings for up to 90 days.
• Travellers from non-VWP countries must apply for a Transit (C) Visa in advance.
