Travelling to the UK is becoming more regulated, and many travellers are now asking how the UK ETA for dual citizens rules affect them. The UK government is gradually introducing the Electronic Travel Authorisation (ETA) system for visa-free visitors, which means millions of travellers must get approval before entry. This change creates confusion, especially for dual citizens who hold more than one passport. Wrong passport use, incomplete applications, or misunderstanding eligibility can lead to denied boarding, travel delays, or even refused entry at the border. Many Nigerians and other global travellers in the UK face stress trying to understand which passport to use and whether they need an ETA at all.
So, what exactly should you do if you hold two nationalities? Which rules apply to you? Here are some common questions travellers ask:
This guide breaks everything down in a simple way. You will learn how the UK ETA system works for dual citizens, which passport to use, and how to avoid costly mistakes. Global Plug Services is here to guide you step by step, helping you handle your ETA application correctly, review your documents, and travel with confidence.
The UK ETA (Electronic Travel Authorisation) is a digital permission to travel to the United Kingdom. It applies to travellers who do not need a visa for short visits such as tourism, business, or family visits. The ETA is linked directly to your passport and checked before you travel.
The UK ETA is not a visa. It is a pre-travel clearance system introduced under UK border control reforms.

| Type | Travel authorisation | Legal entry permission |
| Who needs it | Visa-exempt travellers | Visa-required nationals |
| Application | Online | Detailed process |
| Decision time | Minutes to days | Days to weeks |
The ETA does not guarantee entry. Final approval is given by UK Border Force officers at the border.
The UK ETA becomes fully mandatory from 25 February 2026. This falls under the UK’s move towards a digital immigration system managed by the Home Office.

Understanding the correct documents is essential when dealing with uk eta dual citizenship rules. The UK government requires proof of permission to travel before boarding and at entry.

It depends on the nationality you choose to travel with. British dual citizens are not allowed to apply for a UK ETA because they already have the right to enter the UK. Non-British dual citizens can apply if they use a visa-exempt passport. Travellers using a passport from a visa-required country must apply for a standard UK visa instead of an ETA.
No. British citizens are exempt from the ETA requirement. Travel must be done using a valid British passport to prove the right of entry into the UK. A Certificate of Entitlement can be used where a British passport is not available, as it confirms the Right of Abode under UK law.
This depends on your status. British dual citizens are expected to travel with a British passport to avoid complications. Non-British travellers can use a foreign passport, but the correct travel permission must be in place, either an ETA or a visa. Irish passport holders remain exempt from ETA requirements and can travel freely to the UK. It is important that the passport used matches the travel authorisation.
Using the wrong passport can lead to serious travel disruption. Airlines may refuse boarding if the passport does not match the approved ETA or visa. Delays can also occur at the UK border where further checks are carried out. In some cases, entry may be refused if the required permission cannot be verified. These checks are part of strict compliance rules enforced by the UK Home Office and transport carriers.
Children are subject to the same rules as adults under uk eta for dual citizens. A child who is a British citizen must travel with a valid British passport to enter the UK without an ETA. A child who is not British but holds a visa-exempt passport will need an ETA before travelling. Parents are expected to ensure all documents are correct before departure to avoid delays or boarding issues.
