UK ETA applications are processed through an automated system, so it may be possible to receive an approval on weekends or UK bank holidays.
However, processing during these periods is not guaranteed.
Applicants usually receive a decision by email within one day, but processing can take up to 3 working days if additional checks are required.
Weekends and UK bank holidays are not included when calculating working days.
If you have not received a decision after 3 working days, check your spam or junk email folder.
You must confirm that your UK ETA has been approved before traveling to the United Kingdom.
