UK ETA Dual Nationality – Rules 2026

Key Takeaways

UK ETA and dual nationality 2026: British and Irish dual citizens can't get an ETA; others need just one, linked to the passport they travel on.

Last updated: 19 October 2026

Travelling with two passports? Here’s the crucial rule: you need a UK ETA only if you are not a British or Irish citizen and you travel on a passport from a country on the ETA list. British and Irish citizens, including dual citizens, do not need an ETA and cannot get one. If you hold both a British and Irish passport, you do NOT require an ETA—nor will you need one when you travel on your British or Irish document. This means ETA dual nationality situations mostly apply to third-country combinations: for example, American–Brazilian, Canadian–Italian, or Japanese–Korean passport holders. Yet edge cases abound. What if your British passport has expired? What if you’re eligible for British citizenship by descent but haven’t applied yet? This guide unpacks the rules, edge cases, and practical steps for dual citizens planning UK travel in 2026.

Understanding the Dual Nationality Rule: British and Irish Passports

The central principle is straightforward: British citizens and Irish citizens have automatic right of entry to the UK without any travel authorisation. Therefore, if you hold a British passport, an Irish passport, or both, you are exempt from the UK ETA requirement entirely. This exemption applies regardless of your second, third, or fourth nationality. The UK recognises the Common Travel Area agreement with Ireland, which grants Irish citizens the same freedom of movement as British citizens. Consequently, any traveller with a valid British or Irish passport should use that document for UK entry and ignore ETA applications altogether. However, the practical question emerges: which passport should you actually travel with? The answer depends on your individual circumstances, visa requirements for onward travel, and document validity dates.

If Your British Passport Is Expired or Not Yet Issued

A frequently overlooked scenario: you hold British citizenship by descent or recent naturalisation, but your British passport either expired or hasn’t been issued yet. In this interim period, you cannot use a non-existent or invalid British document to enter the UK. As a British citizen you cannot get an ETA, even on a passport from a country such as the United States, Canada or Australia. You must travel on a valid British passport, or on your other passport with a certificate of entitlement to the right of abode (or on an Irish passport if you have one). The timeline matters: if your British passport application is pending, allow enough time for it to arrive before your trip.

Dual Nationals: Both Passports Visa-Waiver Eligible

Many dual nationals hold two passports that both qualify for visa-waiver entry to the UK. Examples include US–Canadian, US–Australian, Canadian–Australian, or Japanese–South Korean combinations. In these situations you need an ETA if your nationality is on the ETA list – US, Canadian and Australian citizens all need one – but you only need one ETA, linked to the passport you will travel on. Apply with the passport you’re most likely to travel on, as the ETA is linked to that specific passport. Applying for ETAs under both passports is unnecessary and wastes money; one is sufficient.

Mixed Scenarios: One Visa-Waiver, One Visa-Required Passport

Complications arise when you hold one visa-waiver-eligible passport and one that normally requires a UK visa. For instance, you might be a US–Indian dual national, or Canadian–Brazilian. If you travel on your US or Canadian passport, you only need an ETA (cost £20 in 2026). If you travel on your Indian or Brazilian passport, you’ll need a Standard Visitor Visa instead, which requires more documentation, takes longer to process (usually up to 3 weeks) and costs £135 (since 8 April 2026). The practical recommendation: use your visa-waiver passport and apply for the ETA. This is faster, cheaper, and involves less bureaucracy than obtaining a Standard Visitor Visa. However, if your visa-waiver passport is expiring soon and your visa-required passport is new, you might choose to apply for the visa using the other document—plan ahead when possible.

Commonwealth and Non-Commonwealth Dual Citizens

A subtle distinction: many Commonwealth nationals benefit from visa-waiver eligibility, but not all. Citizens of Australia, Canada and New Zealand need an ETA to visit the UK. South Africa, however, is on the visa national list, so South African citizens need a Standard Visitor visa rather than an ETA. However, if you hold dual citizenship with a non-Commonwealth country whose nationals require a UK visa (such as India, China, or Russia), you must use the Commonwealth passport for visa-waiver entry or apply for a full visa using the other document. Some dual nationals hold two Commonwealth passports (e.g., Australian–New Zealand or Canadian–Australian): neither needs a visa for short visits, but you still need one ETA, linked to the passport you travel on. Check the official ETA list on GOV.UK before you travel, as it can change. Additionally, some Commonwealth nations have unique arrangements: for example, Hong Kong BN(O) passport holders historically had different requirements, though as of 2026 they follow standard visa-waiver rules if the passport is valid.

Special Cases: Chagossian and Citizenship by Descent

Two edge cases deserve specific attention. First, there is no special ETA rule for Chagossians. British Overseas Territories citizens, including those with BIOT citizenship, do not need an ETA if they travel on a BOTC passport, while Chagossians who are British citizens cannot get an ETA and must travel on a British passport or with a certificate of entitlement. Second, citizenship by descent (common among those born abroad to British parents) gives you the same rights as any other British citizen, including the right of abode (although you cannot normally pass citizenship automatically to children born outside the UK), but the process of obtaining your British passport can take months. During that waiting period you still cannot get an ETA on your other passport: either wait for your British passport, or travel on your other passport with a certificate of entitlement to the right of abode.

How to Apply for an ETA as a Dual National

When you have determined that an ETA is needed, the application process is identical regardless of dual nationality status. You apply for the ETA using whichever passport you’ll travel on. During the online application, you’ll enter your passport number, issue date, expiry date, and personal details. The application asks whether you have any other nationalities, including ones you have held in the past, but you only scan the passport you will travel on. Crucially, once your ETA is approved, it is tied to that specific passport number. If you later decide to travel on your second passport instead, your first ETA becomes irrelevant—you’ll need a new ETA under the second passport’s number. This is why it’s important to choose your travel passport in advance and stick with it throughout your journey. The ETA costs £20 (as of April 2026), is valid for two years (or until the passport you applied with expires, if sooner), and permits multiple entries to the UK.

Practical Tips and Common Pitfalls

Here are key lessons for dual nationals planning UK trips. First, always carry both valid passports when travelling, even if you only intend to use one for UK entry. Customs officers may ask to inspect both documents, particularly if they notice evidence of dual nationality on your entry card or baggage. Second, never assume you need an ETA; verify your passport’s status on the UK Home Office website before spending time or money on an application. Third, keep your ETA approval confirmation and passport in easily accessible locations during travel, as you may be asked to show proof of authorisation at the border. Fourth, if your travel plans change and you want to switch to your second passport, check whether an ETA (or visa) is needed for that document before assuming you can simply use it at the gate. Finally, do not attempt to apply for ETAs under both passports simultaneously or use false information to obtain multiple authorisations—border officials have access to comprehensive databases and fraudulent applications can result in entry denial and further immigration complications.

Frequently Asked Questions

Do I need an ETA if I hold both British and another passport?

No. British passports grant automatic right of entry to the UK. You do not need an ETA, visa, or any other travel authorisation. Simply travel on your British passport and you’re cleared for entry.

I'm a dual British and Canadian citizen. Do I need a UK ETA?

No – and you cannot get one. As a dual British citizen you must travel on your British passport, or on your Canadian passport with a certificate of entitlement to the right of abode.

My British passport hasn't arrived yet. What if I'm travelling soon?

As a British citizen you cannot get an ETA, even on your other passport. You must travel on a valid British passport, or on your other passport with a certificate of entitlement to the right of abode (or on an Irish passport if you have one).

I hold US and Canadian passports. Do I need an ETA?

Yes. US and Canadian citizens both need an ETA to visit the UK, but you only need one, linked to the passport you will travel on.

Which passport should I use: my visa-waiver or my visa-required one?

Always use your visa-waiver-eligible passport if you have one. This avoids the complexity, cost, and delay of a full visa application. There is no rule forcing you to do so, but your permission must match the passport you travel on: an ETA for a passport from an ETA country, or a visa for a passport from a visa national country.

Can I apply for an ETA under both of my passports?

Technically yes, but it’s unnecessary and wasteful. An ETA is tied to a specific passport number, so you only need one under whichever passport you’ll actually travel on. Applying for both doubles your costs with no benefit.

What if I'm a Chagossian citizen or claim citizenship by descent?

There is no special ETA rule for Chagossians: BIOT citizens travelling on a BOTC passport do not need an ETA, and Chagossians who are British citizens cannot get one. If you are a British citizen by descent, you cannot get an ETA either – travel on your British passport or on another passport with a certificate of entitlement.

Will border officers know I hold two passports?

Possibly, depending on stamps and entry records in your documents. Always carry both valid passports when travelling internationally, as officers may inspect them. Do not attempt to conceal your dual nationality, as this can create serious complications at the border.
