Travelers planning frequent trips should understand how the UK Electronic Travel Authorisation works. With an approved ETA, eligible visitors can enjoy
multiple visits with UK ETA during its validity period, making travel for tourism, business meetings, or family visits more convenient. The authorization generally remains valid for two years or until the linked passport expires, whichever comes first. Each visit can usually last up to six months, subject to immigration permission. Travelers must use the same passport connected to their ETA. A new passport requires a new ETA application before travelling to the United Kingdom
