UK passport holders usually do not need a visa for short tourist or business trips to the United States. Instead, most use the Electronic System for Travel Authorization, known as ESTA, if they qualify under the Visa Waiver Program. A visa is needed in other situations, such as for study, work, long stays or if you are not eligible for ESTA. This guide explains the difference, how long things take and what the B2 visa is. We are not an immigration adviser, and the rules change, so always check the official US government and UK government websites before you apply or travel.
When do I need a visa for the USA?
Whether you need a visa depends on the purpose and length of your trip, your nationality and your travel history. In general terms:
- Short tourist or business visits: many UK travellers can use ESTA instead of a visa, if they meet the eligibility conditions.
- Work, study or long stays: these usually need a specific visa, and you should check the correct category with the official authorities.
- Travellers who are not eligible for ESTA: they may need to apply for a visa. Eligibility can depend on factors such as previous travel to certain countries, past visa refusals or certain criminal or immigration history. The questions on the form are detailed, so read them carefully.
- Transit: even if you are only passing through a US airport, you may need ESTA or a visa, so check the rules for your route.
Because the rules and conditions are specific to each person, do not rely on a general guide alone. Use the official US government resources to confirm what applies to you.
How does ESTA differ from a visa?
ESTA is an electronic travel authorisation, not a visa. It is linked to your passport and is applied for online, and it allows eligible travellers to visit the United States for a limited period under the Visa Waiver Program. A visa is a more detailed permission, usually involving a longer application and in many cases an interview at a US embassy or consulate.
- Application: ESTA is completed online, while a visa generally needs a longer application and often an interview.
- Purpose: ESTA covers short stays for tourism, business or transit, while visas cover a wider range of purposes, including work and study.
- Validity: ESTA authorisations are typically valid for a set period and linked to a passport, while visas have their own conditions. Check the current details on the official site.
- Entry is not guaranteed: neither ESTA nor a visa guarantees entry. Border officers make the final decision when you arrive.
Only use the official ESTA website. There are many third-party sites that charge extra fees for a service you can complete directly, so check that the address is the official government one before entering any details.
What is a B2 visa?
A B2 visa is a US visitor visa for tourism, such as holidays, visiting friends and family or certain medical treatment. It is part of the wider B visitor category, with B1 usually covering business purposes. UK travellers who are eligible for the Visa Waiver Program often use ESTA instead, but a B2 visa may be needed if you are not eligible for ESTA or if you plan a longer stay than the programme allows.
Applying for a B2 visa generally involves completing an online form, paying a fee, providing a photograph and attending an interview. You will need to show the purpose of your trip, that you plan to return home and that you can fund the visit. Check the official US embassy website for the current process and fees.
How long does a US visa or ESTA take?
ESTA applications are often processed quickly, and many approvals are issued within a short time, but this is not guaranteed and some applications take longer. Apply well before your trip, not on the day you travel. Check the official guidance for the recommended lead time.
Visa applications take longer, because they usually involve an interview appointment and administrative processing. Waiting times for appointments vary by location and time of year. Start the process as early as you can and check current waiting times on the US embassy website. If you have a trip planned, avoid booking non-refundable flights until your authorisation is confirmed.
Before you apply: a short checklist
- Check that your passport is valid and meets the entry requirements. If you need to renew it, see our guide to renewing a UK passport online.
- Check whether you are eligible for ESTA by reading the official eligibility questions.
- Use only the official government website to apply.
- Keep a copy of your approval and your travel plans.
- Consider travel insurance. Our travel insurance guide explains what to look for, especially as medical costs in the USA can be very high.
Planning your trip once you are authorised
Once your authorisation is sorted, you can focus on planning. Compare flights and hotels, and consider how you will pay for things abroad. Our travel money exchange comparison explains how to avoid poor exchange rates. For help with a New York trip, see our best time to visit New York guide.

Common mistakes to avoid when applying
Most problems with US travel authorisation come from small errors rather than anything complicated. Taking a few minutes to check the details can save a great deal of stress later.
- Typing errors: a misspelt name, a wrong passport number or a wrong date of birth can cause problems at check-in. Copy the details exactly as they appear on the photo page of your passport.
- Using the wrong passport: authorisation is linked to a single passport. If you hold more than one, apply with the one you will actually travel on.
- Leaving it to the last minute: airlines can check your authorisation before you board, so applying on the day of travel adds unnecessary risk.
- Answering the eligibility questions carelessly: the questions are legal declarations. Read each one properly and answer honestly. If something is unclear, check the official guidance rather than guessing.
- Using an unofficial site: look-alike websites can add their own fees or collect your details. Start from the official government pages and check the web address before you enter anything.
What happens when you arrive in the USA
Having an approved authorisation or a visa is only part of the process. When you land, you will go through border control, where an officer may ask about the purpose of your trip, how long you plan to stay, where you will be staying and when you are going home. Answer calmly and truthfully, and keep your accommodation details and onward or return travel plans easy to find on your phone or on paper.
You may also be asked to give fingerprints and have a photograph taken. This is a normal part of the process for most visitors. Remember that border officers make the final decision about entry, so it is sensible to carry your documents together and to be ready to explain your plans clearly.
Travelling with a connecting flight
If your journey includes a change of plane in the United States, you may still need authorisation, even if you never leave the airport. This catches out some travellers heading to destinations such as Mexico, the Caribbean or Canada via a US hub. When you compare itineraries, look at where each connection is. A route that changes planes elsewhere may avoid the question altogether, although fares and journey times can differ, so compare the options. If you are unsure, check the official guidance for your specific route before you book.
Keeping your documents safe
It is worth keeping a digital and a paper copy of your key documents, stored separately from the originals. That usually means your passport photo page, your authorisation confirmation, your travel insurance details, your flight and accommodation bookings and an emergency contact number. If anything is lost or stolen abroad, having copies makes it much easier to get help from the airline, your insurer or the nearest British consulate. The UK government website has up-to-date travel advice for the United States, and it is worth reading before you go.
Official sources: the official ESTA application is run by US Customs and Border Protection at esta.cbp.dhs.gov, and the GOV.UK USA travel advice page sets out the current entry requirements for UK travellers. Rules, fees and processing times change, so check them shortly before you travel.
Frequently asked questions
Do UK citizens need a visa to visit America?
Often not for short visits, if they are eligible for ESTA. Eligibility depends on your circumstances, so confirm it with the official sources.
Can I use ESTA to work in the USA?
ESTA is for limited purposes such as tourism, certain business activities and transit. It is not a work permit. If you plan to work or study, check which visa you need.
Is the ESTA website official?
Only government-operated pages are official. Many look-alike sites charge higher fees, so navigate carefully and check the address.
Can I be refused entry even with ESTA or a visa?
Yes. Authorisation allows you to travel, but the final decision on entry is made by border officers on arrival.
Do children need their own ESTA?
In general, each traveller needs their own authorisation, including children, who must have their own passport. Check the official guidance for the details.
Do the rules differ for dual nationals or people with other passports?
They can. The authorisation you need depends on the passport you travel on and your circumstances, so check the official guidance for your situation.
What should I do if my ESTA application is not approved?
Check the official guidance on what to do next. You may be able to apply for a visa instead, which usually involves an interview. Avoid booking non-refundable travel until you are sure you can go.
Can I apply for a visa or ESTA for someone else?
Some people complete applications on behalf of family members, but the details must match the traveller exactly and the answers remain the traveller’s responsibility. Check the official rules on applying for others.
Does a criminal record affect my application?
It can. The eligibility questions cover certain types of history, so read them carefully and answer honestly. If you are unsure, seek advice from an immigration professional or the official US embassy.
