Did you know that without a UK Electronic Travel Authorization , you might be turned away at the border? This mandatory travel document is crucial for many travellers planning to visit the UK. Applying for a UK ETA is simple. Use the official UK ETA website. Ensure you have your passport, email and a payment method ready. Decisions are usually made within three working days. Remember, the application costs vary and each traveler, including children, needs their own ETA. Be cautious of other websites that might charge more without offering faster processing, hence, use the official website for your application. With an ETA, you can stay in the UK for up to 6 months for tourism, business, or short-term study. Plan wisely to make the most of your visit, but remember, it doesn't allow long-term stays or work.
