Travelling from the UK to the USA – Passport, ESTA & Entry Requirements
When people search for ESTA USA from UK, they want practical guidance that feels human and trustworthy. This article is written by travellers who have gone through the process many times. It explains what an ESTA is, how to apply, what to avoid, and how to travel with confidence from people who genuinely love visiting the USA.
What is an ESTA and why it matters
An ESTA is the Electronic System for Travel Authorisation, part of the Visa Waiver Program operated by the United States Government. It allows most UK passport holders to visit the country for tourism, business, or transit for up to ninety days.
According to U S Customs and Border Protection, an ESTA is a digital authorisation that is electronically linked to your passport. You will not receive a stamp or a physical document.
From my own experience applying before a trip to Miami, approval often arrives within a few hours, but it is always wise to apply at least three days before travel.
PRO TIP: You can apply through USA ESTA Services. The process is straightforward, secure, and supported by travel advisers who understand what UK visitors need.
What are the requirements for an ESTA USA
According to U S Customs and Border Protection, these are the core requirements for UK citizens applying for an ESTA.
- A valid UK electronic passport with the biometric chip symbol
- A visit for tourism, business, or transit lasting no longer than ninety days
- No current U S visa and no previous overstay in the United States
- No recent travel to restricted countries such as Cuba, Iran, Iraq, or Syria
- Completion of the ESTA form and payment of the official fee
Travellers who meet these conditions are almost always approved automatically.
When I applied before a trip to Boston, I double checked my passport chip symbol and eligibility. It took less than ten minutes to complete everything online.
Who needs an ESTA and who needs a visa
If you are travelling for a short visit, the ESTA is usually all you need. If you plan to stay longer than ninety days, study, work, or you are not eligible for the Visa Waiver Program, you will need to apply for a visitor visa at a U S Embassy or Consulate.
| Topic | ESTA | Visitor Visa |
| Who it suits | UK and other Visa Waiver countries | Travellers not eligible for the programme |
| Purpose | Tourism, short business, transit | Tourism, visiting family, business, medical stays |
| Stay limit | Up to 90 days | Up to 6 months |
| Application | Online form | Embassy interview |

For most UK visitors, the ESTA is simpler, faster, and fully electronic. If you are unsure which option fits your situation, you can contact USA ESTA Services for guidance before you apply.
How to apply for an ESTA step by step
Step 1. Prepare your details
Have your electronic passport, travel dates, first U S address, and a payment card ready.
Step 2. Visit usaesta.co.uk and start the secure form
Enter your information exactly as shown on your passport.
Step 3. Answer the eligibility questions
Read each question carefully and answer truthfully.
Step 4. Review and pay
Double check your name, date of birth, and passport number, then submit the form.
Step 5. Wait for approval
Most approvals arrive within minutes, though U S Customs and Border Protection advise allowing up to seventy two hours.
Step 6. Check your status before travel
You can log back in to confirm your ESTA remains active.
EXPERIENCE TIP: When applying for a family, complete the first form carefully, then reuse those details for the others to avoid small errors.
How long is an ESTA valid for UK citizens
An ESTA remains valid for two years from approval or until your passport expires. You can use the same ESTA for multiple visits, each up to ninety days.
Can I use the same ESTA for multiple trips
Yes. If your passport details remain the same.
How do I check if my ESTA is still valid
You can check status directly on the official CBP portal.
What is the 6-month rule for ESTA
There is no six-month rule for ESTA. Your passport must only be valid for the length of your stay.
Passport rules for travelling to the USA
Many people ask, Can I enter the USA with less than six months on my passport. According to the UK Government travel advice, the answer is yes.
Your passport must be valid for the length of your stay, and it must be an electronic passport.
HELPFUL ADVICE: Some airlines prefer at least six months of validity to avoid confusion. Renew early if your passport is close to expiry so there are no issues at check in.
Common ESTA mistakes and how to avoid them
From experience, most problems come from small errors that are easy to avoid.
- Entering the passport number incorrectly
- Using a name that does not exactly match the passport
- Applying too late
- Travelling soon after visiting restricted countries
When I applied before a family holiday to Los Angeles, I noticed how easy it is to mistype passport digits. Triple checking them avoids a world of stress.
If your ESTA is refused, you can still apply for a visitor visa through the U S Embassy in London.
Can you travel to the USA with a criminal record
Having a criminal record does not automatically prevent travel, but some convictions make a traveller ineligible for the Visa Waiver Program. You must answer all questions truthfully.
According to U S Customs and Border Protection, admission is always at the discretion of the inspecting officer. If in doubt, apply for a visitor visa rather than risk refusal at the airport.
Travelling with children from the UK to the USA
Every person, including infants, needs a passport and ESTA. If a child travels with one parent or another adult, carry a letter of consent from the other parent. Include names, dates, and signatures.
Family applications can be made together, which keeps details consistent and helps prevent errors.
PRACTICAL TIP: Keep all medicines in their original packaging. From experience, this avoids confusion during TSA security screening.
What to expect at the USA border
When you arrive, you will be greeted by an officer from U S Customs and Border Protection. They will review your passport and ESTA and may ask a few short questions about your visit.
Have these ready:
- Passport
- Return ticket or onward plan
- Address where you will stay
Answer politely and clearly. The process is usually quick and professional.
TRAVELLER INSIGHT: Keep a copy of your ESTA confirmation on your phone or printed out in case an airline agent asks to see it at check in.
