Everything You Need to Know About the ESTA Application for the USA

When planning a trip to the United States, one of the most important steps for eligible travelers is completing the ESTA application. ESTA, which stands for Electronic System for Travel Authorization, is an online system used by the U.S. government to pre-screen travelers from Visa Waiver Program (VWP) countries before they enter the United States.

This guide provides an in-depth look at the ESTA application process, what to expect, who is eligible, and how it fits into your overall travel planning. Whether you’re traveling for tourism, business, or transit, understanding the ESTA requirements will ensure your trip goes smoothly.

What is an ESTA Application?

The ESTA application is an automated system that determines the eligibility of visitors to travel to the United States under the Visa Waiver Program. Instead of applying for a traditional U.S. visa, eligible travelers can fill out the ESTA form online, usually receiving an approval within minutes or hours.

An approved ESTA allows you to stay in the United States for up to 90 days for tourism, short-term business, or transit. It's valid for two years or until your passport expires, whichever comes first.

Who Needs to Complete an ESTA Application?

Travelers from Visa Waiver Program (VWP) countries must complete the ESTA application before boarding a flight or ship bound for the U.S. Some of the eligible countries include the United Kingdom, Germany, Japan, France, Australia, and New Zealand, among others.

Even if you’re only transiting through the United States, an ESTA travel authorization is still required. Children and infants must also have their own approved ESTA if they are traveling under the VWP.

If you hold a passport from a non-VWP country, you will need to apply for a U.S. visa through a U.S. embassy or consulate instead of using the ESTA system.

How to Complete the ESTA Application

The ESTA application process is straightforward:

Go to the official ESTA website or a trusted third-party visa assistance provider.
Fill in your personal details, passport information, and travel plans.
Answer a series of security-related questions.
Pay the application fee, typically around $21 USD.
Submit the application and wait for a confirmation email or online update.

Most applications are approved within minutes, but it is recommended to apply at least 72 hours before departure in case additional processing is required.

Common ESTA Application Mistakes to Avoid

While the ESTA application is relatively simple, travelers often make avoidable errors:

Entering incorrect passport numbers or expiry dates.
Failing to update expired passports linked to previous ESTAs.
Applying too close to departure time.
Assuming approval guarantees entry—Customs and Border Protection (CBP) officers have the final say.

Double-check your details before submitting the ESTA form to avoid delays or denial of boarding.

How the ESTA Application Compares to a Traditional U.S. Visa

The ESTA application is much faster and simpler than applying for a U.S. tourist visa (B-2) or business visa (B-1). There’s no need for a consular interview, document submission, or long processing times. However, it comes with certain limitations:

Maximum stay is 90 days.
Cannot extend or change visa status while in the U.S.
Not valid for employment or study.

If your travel purpose doesn’t qualify under the Visa Waiver Program, you must pursue a different U.S. visa type.

If you are applying for an ESTA travel authorization, it's wise to stay updated on U.S. entry requirements and COVID-19 travel advisories. Depending on the season, there may be additional screening at U.S. airports.

In addition, having a return or onward ticket is crucial to demonstrate your intent to leave the United States within the 90-day period. Travelers should also carry proof of financial means, a clear travel itinerary, and valid accommodation details.

Travelers arriving from the UK to the USA under ESTA should also note that even with pre-approval, they may be subject to questioning at the port of entry. Preparing thoroughly for your journey helps ensure a smooth experience.
