What is the ESTA?
The Electronic System for Travel Authorization (ESTA) is an online pre-clearance system run by US Customs and Border Protection. It lets citizens of 40+ approved countries visit the USA without applying for a formal visa. You answer questions online, pay $21, and receive approval (usually within minutes, sometimes up to 72 hours). Your ESTA is then tied to your passport digitally — there is no stamp or sticker.
ESTA allows stays of up to 90 days for tourism, business meetings, conferences, or transit. It does NOT allow work, study, journalism or any paid activity. Overstaying, even by one day, can trigger a 5-year ban from the US.
Which Countries Qualify
The Visa Waiver Program covers 41 countries as of 2026:
- Europe: UK, Ireland, France, Germany, Spain, Italy, Netherlands, Belgium, Switzerland, Austria, Portugal, Greece, Poland, Czech Republic, Hungary, Slovakia, Slovenia, Croatia, Estonia, Latvia, Lithuania, Malta, Iceland, Luxembourg, Norway, Denmark, Sweden, Finland, Liechtenstein, Monaco, San Marino, Andorra
- Asia-Pacific: Japan, South Korea, Taiwan, Singapore, Brunei, Australia, New Zealand
- Americas: Chile
- Israel (most recently added, late 2023)
🇬🇧 UK citizens: You qualify for the ESTA. But if you also hold citizenship of Iran, Iraq, Libya, Syria, North Korea, Somalia, Sudan, Yemen or Cuba, you may be excluded from the VWP and need a B1/B2 visa instead.
If your country is not on the list — or you have dual citizenship with one of the restricted countries — you need a B1/B2 visitor visa from your nearest US embassy. See our B1/B2 visa guide.
How to Apply
The official application is at esta.cbp.dhs.gov. Never use any other website. The process takes 15-20 minutes and needs:
- A passport from a VWP country, valid at least 6 months beyond travel
- An email address
- A credit/debit card for the $21 fee
- Your flight details (optional but speeds processing)
- Address of where you will stay in the US (hotel name/address is fine)
- Emergency contact information
⚠️ Scam warning: Google "ESTA" and the first 5 results are usually scam sites charging $60-100 for a $21 authorization. They are technically legal (they process the application for you) but you do not need a middleman. Go directly to esta.cbp.dhs.gov.
Cost & Validity
| Item | Detail |
|---|
| Fee | $21 USD ($4 processing + $17 authorization) |
| Validity | 2 years, or passport expiry (whichever sooner) |
| Stay per visit | Up to 90 days |
| Multiple entries | Yes — unlimited within the 2-year validity |
| Processing time | Usually minutes; sometimes 72 hours |
| Apply how early | Minimum 72 hours before flight; 2 weeks ideal |
Common Mistakes
- Applying on the wrong website — only esta.cbp.dhs.gov is official
- Lying about past visa refusals — CBP databases are global; always disclose
- Applying too close to travel — leave at least 72 hours
- Not printing your approval — some airlines ask to see it at check-in
- Visiting Iran, Iraq, Sudan or Syria since 2011 — this automatically disqualifies you from VWP
- Using an old passport number — if you renew, you need a new ESTA
What If Denied
If your ESTA is denied ("Travel Not Authorized"), do not panic — it is not a ban. It simply means you must apply for a B1/B2 visa in person at a US embassy. Reasons include: prior overstay, visiting excluded countries, criminal record, giving inconsistent answers, or an unrelated administrative flag. Apply for the B1/B2 well in advance — interview wait times can be 3-12 months depending on country.
Border Inspection
Having an approved ESTA does not guarantee entry. At the airport, a CBP officer still inspects you and decides whether to admit you. They may ask:
- Purpose of your trip
- How long you are staying
- Where you will stay
- Your return ticket
- Proof of funds (rarely)
- Your occupation and employer
Answer briefly and honestly. Do not volunteer information. Carry proof of onward travel (a return or onward flight) and a hotel booking — you may be asked for them. Most inspections take under 2 minutes.
After Arrival
Once admitted, you have up to 90 days. You cannot extend an ESTA stay — if you overstay by even a day, you can face a 5-year ban and future ESTA denial. If you need more time, leave before day 90 and apply for a B1/B2 visa for future longer visits.
💡
Travel insurance is essential. The VWP does NOT cover medical costs. An American ER visit without insurance costs $2,000-15,000.
