Once issued, the ETA is valid for multiple entries over two years or until the passport used for the application expires.
The UK is updating its travel requirements. Soon, all travelers, except British and Irish citizens, will need an Electronic Travel Authorisation (ETA) to enter or transit through the UK, including children. The main reason for introducing this initiative is to enhance national security and streamline travel.
Purposes like tourism, family visits, transit, business, or short-term study are valid reasons for applying for the UK ETA.
