Traveling to the UK as a dual citizen can raise a common question: which passport should you use when applying for your UK ETA? Understanding the rules is essential to ensure a smooth travel experience and avoid unnecessary complications at the border.

What is a UK ETA?

The UK ETA (Electronic Travel Authorization) is an online entry requirement for visa-exempt travelers. It is mandatory for short-term visits, such as tourism, business meetings, or transit, and allows the UK authorities to pre-screen travelers before arrival.

Dual Citizenship and UK ETA

If you hold two passports from different countries, you need to consider which nationality is eligible for the UK ETA. The ETA is only applicable to nationals of countries listed on the UK ETA eligible countries list.

  • Check your eligibility first: Not all passports are accepted. Visit the official list to confirm if either of your citizenships qualifies.

  • Use the eligible passport: Always apply using the passport that is recognized for the UK ETA. If one of your passports requires a visa instead of an ETA, do not attempt to use it for the online application.

Why Choosing the Correct Passport Matters

Using the wrong passport can lead to denied entry, delays, or complications at immigration. The UK ETA is electronically linked to the passport number, so the details must match exactly.

  • Example: If you have both Indian and UAE passports but only the UAE passport is eligible for a UK ETA, you must use your UAE passport for the application.

Steps to Apply for UK ETA as a Dual Citizen

  1. Confirm your eligible passport: Check the UK ETA eligible countries list.

  2. Prepare passport details: Ensure your passport is valid for at least 6 months.

  3. Complete the online UK ETA form: Enter personal information exactly as it appears on your chosen passport.

  4. Pay the UK ETA fee: Payment is done online securely.

  5. Receive ETA approval: Usually within minutes via email.

  6. Travel with the correct passport: At the airport, present the same passport you used to apply.

Tips for Dual Citizens

  • Do not mix passports: Entry and ETA must correspond.

  • Keep copies of both passports, but use only the eligible one at immigration.

  • For frequent travelers, consider which passport offers more travel benefits, like visa-free access to other countries.
