If you plan to visit the United States through the Visa Waiver Program (VWP), you must apply for an ESTA (Electronic System for Travel Authorization). Many travelers ask the same question: how long does USA ESTA last? The answer is straightforward, but there are important details you should know.
First of all, what is USA ESTA?
The USA ESTA is short for Electronic System for Travel Authorization. It is an online approval system used by the United States to check travelers before they board a plane or ship to the country.
ESTA is designed for people coming from countries that are part of the Visa Waiver Program (VWP). This program allows travelers to enter the U.S. without a visa for short visits, like UK ETA.
Here is everything you need to know about USA ESTA
How long does USA ESTA last: Validity explained
A USA ESTA is valid for two years from the date it is approved, or until your passport expires, whichever happens first. This means if your passport expires in less than two years, your ESTA will automatically expire on the same date.

You cannot extend a United States ESTA. Once it expires, you must apply again. A new application comes with the same fee and approval process.
How long can you stay in the U.S. with ESTA
Although an ESTA lasts for two years, it does not allow you to stay in the United States for that full period. Each visit under ESTA has a maximum stay of 90 days.
These 90 days cover not only the U.S. but also trips to Canada, Mexico, or nearby islands if your entry was through the United States. If you need to stay longer than 90 days, you must apply for a different type of visa.
Multiple entries with US ESTA
Your USA ESTA can be used for multiple trips during its validity. As long as it is still active and your passport is valid, you can travel to the U.S. several times without reapplying.

However, border officers may question frequent or long stays. USA ESTA is for short visits like tourism, business, or transit—not for living in the United States. To avoid problems at entry, allow a reasonable gap between trips.
When you need to reapply for USA ESTA
Even if your USA ESTA has not reached the two-year limit, you must apply for a new one in certain cases:
You receive a new passport.
You change your name.
You change your citizenship.
Your answers to ESTA security questions change, such as criminal history or past travel details.
In these cases, your previous United States ESTA becomes invalid, and you need a new approval before traveling again.
How to apply for USA ESTA in 5 steps
Applying for the USA ESTA is fast and entirely online:
Enter your personal and passport details.
Answer the eligibility questions truthfully.
Pay the application fee securely online.
Receive your decision—often within minutes, though it may take up to 72 hours.
Is USA ESTA a visa?
It is important to understand that ESTA is not a visa. It only gives permission to board a plane or ship to the U.S. The final decision on your entry is made by Customs and Border Protection officers at the airport or border.
This means having a valid USA ESTA does not guarantee entry, like US visitor visas. If officers believe you do not meet the requirements, they can refuse admission.
