Electronic Travel Authorisation: checking eligibility

ETA eligibility depends on nationality, immigration status and the proposed travel, so use current official guidance before applying. British and Irish citizens, including dual citizens, are not ordinary ETA applicants and need the appropriate evidence for their own travel position.

Check the passport to be used and any existing permission. An ETA is linked to travel-document details and does not guarantee entry or permit every activity.

Check nationality and existing status first

An ETA is a travel authorisation for eligible visitors, not a general visa for everyone travelling to Britain. The official guidance directs travellers to check the requirement against nationality and purpose. Someone who already has relevant UK permission may not need an ETA, while a visa-national visitor may need a Standard Visitor visa instead. Start with the traveller's complete nationality and immigration position rather than the country from which the flight departs. ^[1]

Make a separate check for every family or group member. Where an ETA is required, babies and children also need their own authorisation. One adult's successful application does not cover a child on the same booking. Keep the passport and decision details matched to each person, especially where names are similar or an organiser is helping several relatives apply at once. ^[1]

Treat British and Irish dual citizens correctly

The official exemption guidance states that dual citizens with British or Irish citizenship cannot obtain an ETA. It identifies the appropriate evidence for travel, including a valid British or Irish passport or another valid passport with a certificate of entitlement to the right of abode, as applicable. A person should not select only their other nationality in order to obtain an authorisation for which their full status makes them ineligible. ^[2]

If the traveller may already be British through a parent or birthplace, resolve that question before applying. Do not assume that never having held a British passport means the person cannot be British. Where another existing permission or an unusual dual-nationality situation is involved, use the current official guidance or obtain individual advice. This can avoid discovering the documentation problem at airline check-in.

Use the passport that will be used for travel

The ETA application requires the passport the traveller will use, an email address, payment details and the required photographs. Check the passport number, nationality, date of birth and expiry carefully before submission. The authorisation is linked to that passport. A spelling or number copied incorrectly from a booking can create a mismatch even where the traveller's identity is otherwise clear. ^[3]

If helping another person, follow the official distinction between applying through the app when they are present and applying online when they are elsewhere. Use accurate photographs and obtain the person's answers rather than guessing their history. Keep the confirmation available to the traveller and ensure they can access the email used. A helper's payment card does not make the helper the holder of the ETA. ^[3]

Wait for approval and check validity before departure

The application guidance says to wait for the email confirming the ETA before travelling. A payment receipt or application reference alone is not confirmation of approval. Decisions for family members may arrive at different times, so check every person individually. The published processing expectations are not a promise that an application made immediately before departure will be completed in time. ^[3]

An ETA normally lasts two years or until the linked passport expires, whichever comes first. Check its current status and the passport before a later trip rather than assuming an old email covers a replacement document. The official service allows an online validity check. If details need changing or an application has been rejected, follow the published next-step instructions instead of attempting to edit a saved confirmation. ^[3]

Review the visit itself separately from the authorisation

An ETA does not guarantee entry or permit unrestricted work, residence or other activities. The traveller must still meet the rules for the intended visit. A business meeting, paid engagement, study plan or family stay may have additional conditions. Use Business visitor activities: what to check where work-related activities are proposed, and assess the full itinerary rather than assuming that an approved ETA settles every immigration question. ^[1]

Through UK visitor application coordination, request an appropriately regulated or otherwise legally authorised adviser if nationality, previous refusals or proposed activities create uncertainty, subject to confirmed scope. For routine applications, use the official service and avoid websites implying that paying an intermediary produces a faster Home Office decision; the application guidance expressly says it does not. Keep the final preparation focused on correct eligibility, matching passport details, approval before travel and a genuinely permitted visit. ^[3]

Illustrative scenario

A dual British citizen considers applying with a foreign passport. They check the official British-citizen travel requirements instead of assuming an ETA is the correct solution.
