I Already Have a US Visa — Do I Still Need a UK ETA?

UK nationality, ETA exemption, application and transit guidance checked against GOV.UK on 14 October 2026. This guide is not an individual immigration assessment.

Separate the document questions

A US visa, US permanent residence and US citizenship are different things. Neither residence in America nor a US visa automatically makes another country's passport eligible for a UK ETA. Start with GOV.UK Check if you need a UK visa.

The visitor visa-national list includes India. An Indian passport holder living in America should not assume a US visa replaces a required UK visit visa.

When an existing UK status changes the answer

Official ETA exemptions include a UK visa or relevant permission to live, work or study in the UK. Check the actual permission and travel document, not simply whether you once held a UK visa.

British and Irish citizens, including dual citizens, cannot get an ETA. A British-American traveller does not become eligible by choosing the US passport for the application. Follow the official citizenship evidence guidance instead.

A US visa may be relevant to travelling back to America, but that is separate from the UK permission being checked here.

Airside transit: ETA exemption is not the visa answer

If a UK connection does not pass border control, no ETA is required for that airside transfer. This exemption should not be described as abolished or limited to travellers who buy an ETA to be safe.

Some passengers may need a Direct Airside Transit visa unless a qualifying exception applies. The official airside guidance sets out document-based exceptions. A qualifying US visa or residence document can matter here, but do not assume every US document qualifies or that an exception permits a UK holiday.

Landside transit is a different assessment

If you cross UK border control, check the Visitor in Transit guidance and applicable exceptions. An ETA-eligible traveller may instead need an ETA unless exempt. A visa-required traveller must check the proper visa or transit exception.

Ask the carrier whether baggage collection, onward check-in or an airport change requires immigration. A short layover and a through-ticket are not substitutes for confirming the actual route.

Two illustrative journeys

Planning examples, not reported passenger cases: a visa-required passport holder living in the US plans a London holiday and checks the UK visitor route. They do not select ETA merely because they already hold a US visa.

Another traveller is changing aircraft without UK border control. They check the separate airside transit-visa exemption using their actual US document. A result for that connection cannot be reused as permission to leave the airport or stay in Britain.

If ETA is the correct route

Use the official application links. The fee is GBP 20. Decisions usually arrive by email within a day but can take up to three working days. Wait for approval; another website cannot secure a faster government decision.

The ETA is linked to the application passport, generally for two years or until that passport expires. It does not determine the length of each permitted visit or guarantee admission. A replacement passport requires another ETA when an ETA is needed.

Key takeaways

• US immigration documents and UK visitor permission are not interchangeable.
• Check nationality, purpose and existing UK permission first.
• British and Irish dual citizens cannot apply for an ETA.
• Airside transit is ETA-exempt, but transit-visa requirements remain separate.
• Document-based transit exceptions do not automatically permit a visit.

For the application itself, see our UK ETA application guide; for connections, read the transit guide. This is general information; verify current official requirements before travel.
