UK ETA for US Citizens 2026: Complete Step-by-Step Guide

If you're a United States citizen planning a trip to the United Kingdom — whether for a holiday, a business trip, a family visit, or even a brief transit — you now need to obtain a UK Electronic Travel Authorisation (ETA) before you travel. This requirement came into effect for US passport holders and marks a significant change for the millions of Americans who visit the UK each year.

This guide explains everything you need to know about the UK ETA as an American: what it is, whether you need one, how to apply, how much it costs, and how quickly you can get it.

What Is the UK ETA?

The UK Electronic Travel Authorisation is a digital pre-entry permission required for travellers from certain countries who do not currently need a visa to enter the United Kingdom. It is not a visa — you will not receive a physical document or stamp. Instead, your ETA is electronically linked to your passport number and is checked automatically when you check in for your flight.

The UK ETA scheme was introduced as part of the UK Government's efforts to improve border security and pre-screen travellers before arrival. It is similar to the US ESTA (Electronic System for Travel Authorization) that non-US citizens need before visiting the United States, or the Australian ETA for visitors to Australia.

Do US Citizens Need a UK ETA?

Yes. United States citizens are required to hold a valid UK ETA for all travel to the United Kingdom that does not require a visa. This includes:

• Tourism and holidays — sightseeing, visiting friends and family, leisure travel
• Short business trips — attending meetings, conferences, or negotiations (not taking paid employment)
• Transit and layovers — if you are transiting through a UK airport without a visa
• Family visits — visiting relatives who live in the UK
• Short-term study — courses lasting less than 6 months

Without a valid ETA, you risk being denied boarding by your airline before you even reach the UK.

How Long Is a UK ETA Valid?

A UK ETA is valid for two years from the date of issue, or until your passport expires — whichever comes first. During those two years, you can make as many trips to the UK as you like, each for up to 6 months at a time.

This means once you have your ETA, you do not need to reapply for every trip. One ETA covers all your UK travel for the validity period.

How Much Does the UK ETA Cost?

The UK Government charges a fee of £10 (approximately $13 USD) for each ETA application. However, if you are applying through a service like Swift ETA, the total cost is $42 USD, which includes:

• UK Government ETA fee: $27 (£20)
• Service and submission fee: $15

Wait — you may have noticed a discrepancy. The UK Government changed its fee structure, and the current fee at time of writing is £20 per person (approximately $27 USD). Always verify the current fee at eta.homeoffice.gov.uk.

How to Apply for a UK ETA as a US Citizen

You can apply for your UK ETA in two ways:

Option 1: Apply Directly with the UK Government

The official UK ETA application is available at eta.homeoffice.gov.uk. You will need to:

• Download the UK ETA app (available on iOS and Android), or apply via the web portal
• Provide your personal details (name, date of birth, nationality)
• Upload a photo of your passport
• Answer eligibility questions about your travel history and background
• Pay the government fee by credit or debit card

Processing typically takes a few hours, but can take up to 3 working days.

Option 2: Apply Through Swift ETA (Recommended for Peace of Mind)

Many travellers choose to use a service like Swift ETA to avoid the risk of making mistakes on their application. Our team reviews your details, submits the application on your behalf, and emails you the confirmation once approved.

Why use Swift ETA?

• Human review catches errors before submission
• Applications submitted within 2 hours of ordering
• Express processing available for urgent applications (delivered within 6 hours)
• Money-back guarantee if we make an error
• Simple email support at hello@swifteta.com

What Information Do You Need to Apply?

Regardless of how you apply, you will need the following information:

• Your passport — must be valid and should not expire before your travel date
• Passport number — exactly as printed on the photo page
• Passport issue and expiry dates
• Date of birth
• Email address — for your confirmation and any correspondence
• Travel date — your intended date of arrival in the UK
• Purpose of visit

You will also need to answer standard eligibility questions. These cover:

• Any previous criminal convictions
• Whether you have been refused entry to the UK or any other country
• Whether you have previously been deported or removed from any country

Answering these questions honestly is essential. Providing false information is a serious offence and will result in your ETA being revoked and your entry to the UK being denied.

How Long Does UK ETA Approval Take?

The UK Government aims to process most applications within a few hours, though it can take up to 3 working days. The vast majority of applications from US citizens are approved quickly, as the background checks are automated and most travellers have no issues.

Through Swift ETA:

• Standard plan ($42): ETA delivered within 24 hours
• Express plan ($55): ETA delivered within 6 hours

What Happens After Approval?

Once your ETA is approved:

• You will receive a confirmation email from the UK Government (or from Swift ETA if you applied through us)
• Your ETA is linked to your passport number electronically — there is nothing to print or carry
• When you check in for your flight, the airline will verify your ETA automatically
• When you arrive at UK passport control, your ETA is verified automatically

You do not need to show any document at the airport. Your ETA is checked electronically.

Can a UK ETA Be Refused?

Yes. An ETA can be refused for several reasons, including:

• A criminal record or pending charges
• Previous UK visa refusals
• Previous deportation from the UK or another country
• Providing false or inaccurate information on the application
• Concerns about your intended length of stay

If your ETA is refused, the UK Government will inform you of this by email. You may be able to apply for a UK Standard Visitor Visa instead, depending on your circumstances.

If your ETA is refused because of an error made by Swift ETA during the application process, we will issue a full refund.

Tips for a Successful UK ETA Application

• Apply well in advance — don't leave it to the last minute. Apply at least 72 hours before your travel date.
• Check your passport — make sure it is valid and will not expire before your planned return date.
• Use your correct passport details — a single digit error in your passport number can cause your application to fail.
• Answer all questions honestly — there are no "safe" lies on ETA applications.
• Keep your confirmation email — while you don't need to show it, it's good to have proof of your ETA.

Frequently Asked Questions from US Citizens

Do I need an ETA if I'm only transiting through a UK airport?

Yes, in most cases. If you are transiting through a UK airport — even without leaving the airport — you generally need either a UK ETA or, in some cases, a Direct Airside Transit Visa. US citizens will need an ETA even for transit.

Can I apply for an ETA on arrival in the UK?

No. You must obtain your ETA before you travel. Airlines are required to check that passengers have a valid ETA before allowing them to board.

Does my Green Card affect my ETA requirement?

No. Your ETA eligibility is based on your passport nationality, not your US immigration status. As a US passport holder, you need an ETA.

What if my passport is about to expire?

Your ETA is linked to your current passport. If your passport expires before your ETA, you will need a new ETA when you renew your passport.

Applying for a UK ETA as a US citizen is straightforward, but getting the details right matters. If you'd prefer to have an expert handle the process for you, Swift ETA charges just $42 — with a money-back guarantee if anything goes wrong on our end.
