Travelers transiting through UK airports.

The ETA is valid for two years or until your passport expires, whichever comes first.
It allows multiple entries into the UK, with each stay permitted up to six months.
Tips for a Smooth Application Process
Apply Early: While processing typically takes up to three days, it’s advisable to apply as soon as your travel plans are confirmed to account for any unforeseen delays.
Ensure Accuracy: Double-check all information entered during the application to prevent errors that could lead to delays or denial.
Stay Informed: Regularly check the official UK government website for any updates or changes to the ETA requirements.
Common Mistakes to Avoid
Procrastination: Waiting until the last minute to apply can result in unnecessary stress or travel disruptions if your ETA is delayed.
Incorrect Information: Inaccurate details can lead to application denial. Ensure all information matches your passport exactly.
Assuming Exemption: Even if you’ve previously traveled to the UK without prior authorization, the new ETA requirement applies to many travelers who were previously exempt. Verify your status before traveling.
Overlooking Transit Requirements: An ETA is required even if you’re only transiting through a UK airport en route to another destination.
