The UK ETA (Electronic Travel Authorisation) is a digital travel permission introduced for eligible travellers visiting the United Kingdom for short stays. It is designed to make the entry process quicker and more secure for visitors travelling for tourism, business, short-term study, or certain permitted activities. The ETA is linked electronically to your passport and must be obtained before travelling. Having an approved ETA does not guarantee entry, as UK Border Force officers make the final decision upon arrival. Travellers should apply well before departure and ensure all information submitted is accurate to avoid unnecessary travel delays.
