If you're traveling to the UK as early as this week, you may need to apply online for travel authorization before you leave.
From Wednesday, Britain will require citizens of the US, Canada and citizens of more than three dozen other countries to have a so-called electronic travel authorization, or ETA.
Here's what travelers should know:
What is an electronic travel authorization?
An ETA is a pre-authorization for travelers from countries where the UK does not require visas.
The UK launched the program in 2024 for visiting citizens from Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the United Arab Emirates. It will go into effect in many additional countries on Wednesday.
Travelers will still need to clear immigration upon arrival. The United States requires an ETA for citizens of European Union countries, the United Kingdom and other countries whose citizens do not require a visa to enter. Later in 2025, EU countries will require them for US citizens and citizens of other countries who meet similar criteria.
You don't need an ETA if you have a visa and can live, work or study in the UK
How can I get it?
You can apply online using the UK ETA application for Android AND iPhone. It costs £10 (about $12.50) to apply and is valid for two years and visits of up to six months. The fee is paid by credit card.
To apply, travelers will need to upload photos of their passport and themselves.
How long does it take?
Applicants could wait about three days for a decision sent by e-mail.
What about children?
Everyone eligible for an ETA will need one, including babies and children.
What happens if I connect in the UK?
You will need an ETA even if you are traveling to a UK airport to connect to another country.
