The Electronic System for Travel Authorization (ESTA) is an automated online system managed by U.S. Customs and Border Protection (CBP). It determines whether visitors from Visa Waiver Program (VWP) countries are eligible to travel to the United States without obtaining a traditional visa. If you are planning a trip to the U.S. for tourism or business lasting 90 days or less, ESTA is likely the authorization you need.
This comprehensive guide covers everything you need to know about ESTA – from what it is and who needs it, to how to apply, check your status, and understand the costs involved.
What Is ESTA and Why Is It Required?
ESTA was mandated by the Implementing Recommendations of the 9/11 Commission Act of 2007. The system collects biographic information and answers to Visa Waiver Program eligibility questions from travelers. It is important to understand that ESTA authorization only permits travel to a U.S. airport, border, or port of entry – a CBP officer makes the final determination of admissibility upon your arrival.
ESTA became mandatory for travel by air or sea from January 12, 2009. Since October 1, 2022, ESTA is also required for entry by land. Airlines may be fined if they transport passengers traveling under the VWP without valid ESTA authorization.
Who Needs an ESTA?
Every traveler entering the United States under the Visa Waiver Program needs an approved ESTA, regardless of age. This includes infants and children. Each person must have their own individual ESTA authorization. You need ESTA if:
- You are a citizen or national of a VWP-designated country
- You are not in possession of a valid U.S. visitor’s visa
- Your travel is for 90 days or less
- Your purpose of travel is tourism, business, transit, or medical treatment
- You are arriving by air, sea, or land
You do NOT need ESTA if you already hold a valid U.S. visa, are a U.S. citizen, or are a U.S. permanent resident (Green Card holder).
Which Countries Participate in the Visa Waiver Program?
As of 2026, citizens and nationals of 42 countries may travel to the United States under the Visa Waiver Program. These countries include:
| Region | Countries |
|---|---|
| Europe | Andorra, Austria, Belgium, Croatia, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Malta, Monaco, Netherlands, Norway, Poland, Portugal, San Marino, Slovakia, Slovenia, Spain, Sweden, Switzerland, United Kingdom |
| Asia-Pacific | Australia, Brunei, Japan, New Zealand, Singapore, South Korea, Taiwan |
| Americas | Chile |
| Middle East | Israel, Qatar |
Note: British citizens are eligible for the VWP, but other categories of UK nationals may not qualify. Only holders of biometric passports are eligible for ESTA travel.

What Information Is Required?
The ESTA application collects the following mandatory information:
- Full name and gender
- Other names or aliases, if any
- Date and city of birth
- Country of nationality and passport details
- Passport number and expiration date
- Home address
- Parents’ names, if known
- Employer information, if applicable
- Emergency contact details
- U.S. point of contact information
You will also need to answer yes/no eligibility questions regarding health conditions, criminal history, immigration violations, and travel to certain restricted countries.
ESTA Processing Time
In most cases, ESTA applications receive a response within seconds. However, CBP strongly recommends submitting your application at least 72 hours before travel. Some applications may require additional processing time, particularly if the applicant has had previous U.S. visa refusals or other complicating factors.

ESTA Validity and Duration
An approved ESTA is generally valid for two years from the date of authorization, or until your passport expires, whichever comes first. During this validity period, you can make multiple trips to the United States without reapplying.
However, there are some important limitations:
- Each stay in the U.S. cannot exceed 90 days
- Time spent in Canada, Mexico, Bermuda, or Caribbean islands (if you arrived through the U.S.) counts toward your 90-day limit
- You cannot extend your stay under the VWP – if you need more than 90 days, you must apply for a visa
- You must obtain a new ESTA if you get a new passport, change your name, gender, or country of nationality

What Happens After You Are Approved?
Once approved, your ESTA authorization is electronically linked to your passport. You do not need to print anything, though keeping a copy of your application number is recommended. When you check in for your flight or arrive at a U.S. port of entry, the airline and CBP will verify your ESTA status electronically.
Important: ESTA approval does not guarantee entry into the United States. A CBP officer at the port of entry makes the final decision on your admissibility. You may be questioned about the purpose of your visit and asked to provide supporting documentation.
ESTA Denials and What to Do
If your ESTA application is denied, you will receive a “Travel Not Authorized” message. Common reasons for denial include:
- Previous immigration violations
- Criminal history
- Providing false or incomplete information
- Travel to restricted countries (Iran, Iraq, Libya, North Korea, Somalia, Sudan, Syria, Yemen, or Cuba)
- Dual nationality with certain countries
If denied, you may still apply for a traditional nonimmigrant visa at a U.S. Embassy or Consulate. The visa application process is more extensive but provides an opportunity to explain any issues that led to the ESTA denial.
ESTA and U.S. Territories
ESTA is also required for travel under the VWP to U.S. territories including Puerto Rico, the U.S. Virgin Islands, Guam, and the Northern Mariana Islands. Note that Guam and the Northern Mariana Islands have an additional visa waiver program for certain nationalities that requires a different electronic authorization. Travel to American Samoa requires a separate permit.
Avoiding ESTA Scams
The only official website for ESTA applications is esta.cbp.dhs.gov. Be cautious of third-party websites that charge excessive fees or claim to expedite your application. These unauthorized services may charge many times the official fee and could put your personal information at risk. Always verify you are on the official government website before entering any personal data.
Frequently Asked Questions About ESTA
How long does it take to get an ESTA approved?
Most ESTA applications are approved within seconds of submission. However, CBP recommends applying at least 72 hours before your departure date. Some applications may require additional processing time and could take up to 72 hours or longer to receive a decision.
How much does ESTA cost?
The total ESTA fee is $40.27 USD. This includes a $10.27 application processing fee and a $30.00 authorization fee for approved applications. Payment can be made using MasterCard, VISA, American Express, Discover (JCB or Diners Club only), or PayPal.
Can I travel to the U.S. while my ESTA is pending?
No, you should not travel to the United States until you have received ESTA authorization. CBP recommends applying at least 72 hours before your departure. If your application is still pending, you should wait for the decision before making travel arrangements.
Do I need a new ESTA for each trip?
No, an approved ESTA is valid for two years (or until your passport expires) and allows multiple entries to the United States. You only need to reapply if your ESTA expires, you get a new passport, or your personal information changes.
Can I work in the U.S. with an ESTA?
No, ESTA does not authorize employment in the United States. The Visa Waiver Program is strictly for tourism, business meetings, transit, and medical treatment. If you intend to work in the U.S., you must obtain an appropriate work visa.
What if my ESTA application is denied?
If your ESTA is denied, you may apply for a nonimmigrant visa at a U.S. Embassy or Consulate. The visa process involves an interview and more extensive documentation, but it gives you the opportunity to address any issues that caused the ESTA denial.
Is ESTA the same as a visa?
No, ESTA is not a visa. It is a travel authorization that allows you to board a carrier bound for the United States under the Visa Waiver Program. ESTA does not guarantee entry – a CBP officer at the port of entry makes the final admissibility determination.
