Starting January 8, 2025, new travel regulations will require US, Canadian, and many non-European passport holders to obtain an Electronic Travel Authorization (ETA) before entering or transiting through the United Kingdom. This applies to all parts of the UK, including Northern Ireland and British Overseas Territories, unless travelers already have a valid UK visa or legal residency in the UK or the Republic of Ireland.
Starting April 2, 2025, the ETA requirement will expand to include most European countries. However, travelers from China and India will not be eligible for an ETA and will still need to apply for a visa.
The ETA is similar to the ESTA in the US. It is part of the UK’s move toward a computerized border system, which streamlines the entry process and improves security.
An ETA is required for all US nationals traveling to or passing through UK airports without a visa or proof of residency in the UK or Ireland.
Travelers can apply for the ETA online via the official UK government website: Apply for an ETA. To avoid last-minute travel issues, it is advised to apply ahead of time.
