It usually takes about 10 to 20 minutes to complete a UK ETA application.
Applicants need to enter passport details, personal information, contact information, and answer eligibility-related questions, so it is recommended to complete the form carefully with enough time.
The information entered must match the passport details exactly. Incorrect information may affect the application result or travel procedures.
Also, after the application has been submitted, information cannot be edited, so it is important to carefully review all details, including your name, date of birth, passport number, and nationality, before submission.
