What is ESTA?
ESTA stands for Electronic System for Travel Authorization. It is an automated online system that determines whether citizens of Visa Waiver Program (VWP) countries are eligible to travel to the United States without a visa.
Plain English
ESTA is not a visa. It is pre-travel permission that allows citizens of eligible countries to board a flight to the US for stays of up to 90 days without going through a full visa application process. It is faster, cheaper, and requires no interview — but it is only available to citizens of the 42 countries in the Visa Waiver Program.
ESTA was introduced in 2009 as part of the Visa Waiver Program's enhanced security framework. Before boarding a US-bound flight or cruise, every VWP traveller must have an approved ESTA — airlines and cruise lines check this at check-in and will deny boarding if ESTA is not approved.

Which countries are eligible for ESTA?
As of May 2026, the following 42 countries participate in the Visa Waiver Program. Citizens of these countries may apply for ESTA rather than a B-2 visa.
⚠ Dual citizens — read this carefully
If you hold dual citizenship — one VWP country and one non-VWP country — you must travel on your VWP country passport to use ESTA. If you travel on your non-VWP passport, you need a B-2 visa regardless of your other citizenship. Additionally, dual citizens who have also held citizenship in Iran, Iraq, North Korea, Sudan, Syria, Libya, Somalia, or Yemen since March 1, 2011 are not eligible for ESTA and must apply for a B-2 visa.
If your country is NOT in the Visa Waiver Program
If you are a citizen of India, Nigeria, Pakistan, Bangladesh, the Philippines, Brazil, Colombia, Ghana, Nepal, Vietnam, or most other countries in South Asia, Africa, and Latin America — you are not eligible for ESTA and must apply for a B-2 tourist visa.
This site is primarily for you. The ESTA page is here because every page on the site links to it from the navigation — but the detailed guidance on this site is built for non-VWP applicants navigating the full B-2 visa process.
Start with your country guide or the main application guide:
What disqualifies you from ESTA?
Even as a citizen of a VWP country, you may not be eligible for ESTA if any of the following apply. These factors are checked automatically by the ESTA system and by US border officers.
Previous US visa denial or overstay
If you have ever been denied a US visa, refused admission at a US port of entry, or overstayed a previous authorised period — you are not eligible for ESTA. You must apply for a B-2 visa.
Travel to certain countries since January 1, 2011
If you have travelled to Iran, Iraq, North Korea, Sudan, Syria, Libya, Somalia, Yemen, Cuba, or Venezuela since January 1, 2011, you are not eligible for ESTA and must apply for a B-2 visa. Travel for official diplomatic or military purposes may be exempt.
Dual citizenship with a non-eligible country
Dual citizens who hold or have held citizenship in Iran, Iraq, North Korea, Sudan, Syria, Libya, Somalia, or Yemen since March 1, 2011 are not ESTA-eligible, regardless of their VWP country citizenship.
Criminal history
Any arrest or conviction — including minor offences in some countries — may disqualify you from ESTA. If in doubt, answer the security questions honestly. Misrepresentation on ESTA is a serious criminal offence.
Certain health conditions
Specific communicable diseases or public health concerns may disqualify you. The ESTA application asks relevant health questions that must be answered honestly.
Non-electronic (non-biometric) passport
To use ESTA you must have an e-Passport (electronic/biometric passport) with a chip. Most passports issued since 2007 qualify. If your passport does not have the international e-Passport symbol on the cover, you may need to renew it before applying.
How to apply for ESTA — step by step
⛔ Only apply at the official US government website
The only legitimate ESTA application website is esta.cbp.dhs.gov. Dozens of third-party websites charge $30–$100+ to "help" with ESTA applications — they are unnecessary. The official site is straightforward, costs $21, and is the only legally valid application channel. Never pay a third party to submit an ESTA on your behalf.
Check your eligibility
Confirm your country is in the VWP list above. Check that none of the disqualifying factors apply to you. If you have any doubt — particularly about travel to restricted countries or criminal history — apply for a B-2 visa instead. Misrepresentation on ESTA is a criminal offence.
Go to the official site — esta.cbp.dhs.gov
Create a new application. Have your passport ready — you will need your passport number, issue date, expiry date, country of issuance, and personal details exactly as they appear on the passport. Any discrepancy between your ESTA and your passport at boarding will cause problems.
Complete the application form
Answer all security and eligibility questions honestly. The form asks about criminal history, travel to restricted countries, health conditions, and other eligibility factors. Answer truthfully — incorrect answers can result in denial, deportation, and a permanent bar on future US entry.
Pay the $21 fee
Payment is by credit or debit card. The $21 fee is charged regardless of whether the application is approved, pending, or denied. There is no refund.
Wait for the decision
Most applications receive one of three responses: Authorisation Approved (you may travel), Authorisation Pending (check back within 72 hours), or Travel Not Authorised (you must apply for a B-2 visa). Apply at least 72 hours before travel — ideally several days before, to leave time for a pending response.
Save your ESTA number
Note your application number and ESTA authorisation number. You do not need to print ESTA — your authorisation is linked to your passport number in the system. Airlines and cruise lines verify it electronically at check-in. Keep your application number in case you need to check your status.
After ESTA approval — what to know
- Validity: Your ESTA is valid for 2 years from the date of approval, or until your passport expires — whichever comes first. During that 2 years you can make multiple trips to the US without reapplying, as long as each stay is 90 days or less.
- Maximum stay per trip: 90 days. This is absolute — there is no way to extend an ESTA-based stay. If you need to stay longer than 90 days, you must depart and reapply for ESTA for a future trip, or apply for a B-2 visa before you travel.
- CBP decides at the port of entry: An approved ESTA does not guarantee entry to the US. US Customs and Border Protection (CBP) officers at the port of entry make the final admission decision. If the officer has concerns, they can deny admission regardless of ESTA status.
- 90-day reset is not automatic: You cannot simply leave the US for a day and return for another 90 days indefinitely. CBP is alert to patterns of VWP abuse — frequent short trips followed by immediate return may result in denial of entry or ESTA revocation.
- Update your ESTA if your circumstances change: If you are arrested, travel to a restricted country, or your passport changes, you must update your ESTA application or apply for a new one. Failure to disclose material changes is misrepresentation.
- No work permitted: ESTA allows tourism, visiting family, brief business meetings, and transit only. Working for pay is strictly prohibited. Violations result in deportation and permanent bars on future US entry.
If ESTA is denied — "Travel Not Authorised"
If your ESTA application returns "Travel Not Authorised," you cannot travel to the US under the Visa Waiver Program. You must apply for a B-2 tourist visa at a US consulate or embassy in your country.
A "Travel Not Authorised" response means the automated ESTA system could not confirm your eligibility for the Visa Waiver Program. It does not mean you are banned from the US. You can still apply for a B-2 visa, attend a consular interview, and demonstrate your eligibility through the normal visa process. The consular officer evaluates your application independently of the ESTA result.
Common reasons for ESTA denial include: a previous US visa refusal, previous overstay, travel to a restricted country, criminal history (even minor), discrepancy between ESTA information and passport data, or dual citizenship with a non-eligible country. When applying for a B-2 visa after ESTA denial, you must disclose the ESTA denial on the DS-160 if asked.
Common ESTA mistakes — avoid these
- Applying through a third-party website. Only esta.cbp.dhs.gov is legitimate. Third-party sites charge unnecessary fees and sometimes submit incorrect information.
- Passport number typos. A single wrong digit in your passport number links the ESTA to a non-existent passport. The airline cannot verify it and you will be denied boarding. Double-check every character.
- Answering security questions dishonestly. Misrepresenting criminal history, travel to restricted countries, or health conditions on ESTA is a federal criminal offence. Answer every question truthfully, even if you think the answer might cause problems.
- Applying the night before travel. Most applications are approved instantly, but some go into "Pending" status for up to 72 hours. Apply several days before travel to leave time for a pending response.
- Assuming ESTA guarantees entry. CBP makes the final decision at the border. An approved ESTA is not a guarantee of admission — it is permission to board the plane and request entry.
- Not renewing ESTA when the passport is renewed. Your ESTA is tied to the specific passport number used in the application. When you get a new passport, your old ESTA is invalid — you must apply for a new one with the new passport details.
- Trying to stay longer than 90 days. 90 days is the absolute maximum on ESTA. There is no extension mechanism. Overstaying triggers a bar on future US entry.
