The UK ETA app simplifies the process of applying for an electronic travel authorization (ETA) to visit the UK. Users can easily apply for themselves or on behalf of someone else, provided they are together during the application process.

To use the app, users need to take a photo of their passport, access the chip in the passport if available, scan their face, take a selfie, and answer personal questions. Payment for the application can be conveniently made within the app.

Before starting the application, users must be in a well-lit area and have their original passport, a payment method, and access to emails. The application process typically takes around 10 minutes and requires an iPhone 7 or newer with iOS 15 or later.

For quick processing, decisions are usually received within 3 working days, linked to the applied passport. No additional documents are necessary for travel to the UK, as the ETA is electronically linked to the passport used for the application.
