If you’re planning a trip to the United States and you’re from a Visa Waiver Program country, there’s a good chance you’ll need to fill out the US ESTA online application before boarding your flight. It’s a simple approval that helps the U.S. government confirm that you’re allowed to travel. Most travelers can apply from their phone or laptop in just a few minutes. But before you begin, it’s helpful to understand how the system works and what to expect along the way.
In this guide, you’ll learn how the process works, who needs to apply, how long it takes, and what to do if there’s a problem with your application.
What Is ESTA?
ESTA stands for Electronic System for Travel Authorization. It is not a visa. It is an online approval that allows travelers from certain countries to visit the U.S. without getting a traditional visa.
If your country is part of the Visa Waiver Program (VWP), you need this approval before flying to the U.S. It’s meant for short visits — tourism, business trips, or transits — that last up to 90 days.
Who Needs to Apply?
Only citizens of Visa Waiver Program countries can apply for ESTA. These include countries like the UK, Germany, France, Japan, and many others. If you hold a passport from one of these countries and you’re planning to visit the U.S., you must apply online.
Important: ESTA is not for everyone. If you’re from a country not listed under the VWP (like India), you’ll need to apply for a regular U.S. visa instead.
When Should You Apply?
It’s best to apply at least 72 hours before your departure. Some people get approved within minutes, but others might face delays if more checks are needed.
Once approved, your ESTA is valid for two years, or until your passport expires — whichever comes first. You can enter the U.S. multiple times within this period, but each visit must be under 90 days.
What Information Do You Need?
Before starting your application, make sure you have the following:
- A valid passport from a Visa Waiver Program country
- A working email address
- A credit or debit card to pay the fee
- Your travel details (flight and accommodation if available)
The form will ask for basic personal details, passport info, and a few security-related questions.
How Much Does It Cost?
The current fee for an ESTA application is $21 USD. You pay this online using a card. Some websites may charge more if they offer additional services, but the official fee through the U.S. government is always the same.
How Long Does It Take?
Most people get a response within minutes, but in some cases, it can take up to 72 hours. You will get an email once your application is approved. It’s a good idea to print the confirmation or save it on your phone, though most airlines will be able to check it electronically.
What Happens After Approval?
Once approved, you’re allowed to board a flight to the United States. But remember — ESTA approval does not guarantee entry. When you arrive, the final decision is made by a border officer at the airport.
Can You Reapply If Denied?
Yes, but only under certain conditions. If your application is denied due to incorrect information, you may fix it and apply again. If your situation has changed (like a new passport or travel reason), you can also try again. Otherwise, if you’re not eligible, you may need to apply for a regular visa.
What If Your Passport Changes?
Your ESTA is linked to your passport number. If you get a new passport, your old ESTA becomes invalid. You’ll need to submit a new application with your updated passport.
Why People Choose to Apply Online
Many travelers find the ESTA process simple and quick when done online. You can apply from home, and there’s no need to visit an embassy. Plus, the process helps speed up entry at U.S. airports, making your travel smoother.
You should always use the official government website to apply. There are many third-party websites that offer the same service but charge more. These are not scams, but they do cost extra for something you can do on your own.
If you want to save time and avoid paying more than needed, applying through the official US ESTA portal is the best choice.
