US ESTA frequently asked questions and requirements for 2025

Many travelers can apply for an Embassy Visa to enter the United States. However, certain nations are exempt through the ESTA (Electronic System for Travel Authorization) visa waiver program. This comprehensive guide answers the most common questions about obtaining and using an ESTA for US travel in 2025.

What is the US ESTA, and how does it work?

• The Electronic System for Travel Authorization (ESTA) is a computerized visa waiver program that helps official authorities determine if a traveler can enter the US.

• Unlike traditional visas, ESTA applications are processed online without embassy visits.

• The program offers multiple entries over 2 years with stays up to 90 days per visit.

"ESTA is designed for low-risk travelers, but it still requires accuracy," says a former U.S. visa officer, Christa Byker. "A tiny error, like entering your passport number incorrectly, can get you denied instantly."

Who is eligible for a US ESTA, and what do you need?

To apply for a US ESTA through iVisa, you need:

• An electronic passport with a digital chip containing biometric information
• Passport validity for at least 6 months beyond your intended stay
• Your passport number and Personal Identification Number (PIN)
• A valid email address
• Payment method (credit/debit card or PayPal)

“I thought my ESTA would be approved immediately, but I accidentally put the wrong passport number,” shared Leah from Auckland. “Had to reapply and delay my flight by two days.”

What problems can come up during the ESTA process?

While applying for an ESTA is generally straightforward, some travelers encounter specific challenges. We at iVisa help address these common situations:

Application timing and processing:

• Standard processing (24h): Best for regular travel planning
• Rush processing (4h): Ideal for upcoming trips
• Super rush processing (30min): Perfect for last-minute travel needs

“Even a typo or old visa denial can lead to an ESTA rejection,” Christa warns. “Apply early so you have time to pivot if needed.”

Pro tip: Based on customer feedback, we recommend applying at least 72 hours before travel, even when choosing super rush processing, to allow time for any potential corrections.

What documents do I need for different types of US travel? 📄

No one loves paperwork, but here's your cheat sheet so you don’t end up fumbling at check-in:

Special considerations:

• Dual citizens must use the same passport throughout their travel
• Previous visa denials require detailed explanation
• Recent passport renewals may need additional verification

"The application is short, but there are some trick questions," says Christa. "If you’ve ever held another nationality or traveled to restricted countries, answer carefully and be ready to explain."

Can I update my travel dates after approval?

Yes. Your ESTA remains valid for two years regardless of specific travel dates. You don't need to update your application if your travel plans shift.

What happens if my passport expires during my ESTA validity period?

You'll need to reapply. Your ESTA is tied to your passport number. Once your passport expires, the ESTA becomes invalid, even if it's within the 2-year window.

Do children need their own ESTA?👶

Yes. Every traveler, no matter how tiny, needs an ESTA. We help parents navigate this process easily, so no toddler is left behind.

Can I enter the US more than once with my ESTA?

Yes. ESTA allows for multiple entries within the 2-year validity. Each visit can last up to 90 days.

What if I made a mistake on my ESTA application?

If you spot a mistake before submission, we can help correct it. But if your ESTA has already been approved with an error, like a misspelled name or incorrect passport number, you’ll need to submit a new application.

“ESTA systems don’t leave room for error. Even a missing letter in your name can trigger a denial,” says Christa.

Can I renew my ESTA, or do I need to reapply?

There’s no renewal process. When your ESTA expires or if you get a new passport, you must start a new application from scratch.

Will a previous visa or ESTA denial affect my new application?

Yes, but not always negatively. Prior denials stay on record and may influence your future ESTA results, especially if the issue is unresolved.

“Even five years after a denial, your case might still get flagged,” Christa says. “But you could also be approved. That’s why verifying eligibility and applying early is key.”

You may still be eligible if your denial was based on something small or outdated. Our team helps you reduce mistakes and know when to escalate to a visa instead.

What happens if my circumstances change after I get approved?

Life changes, like applying for a visa, traveling to a flagged country, or even changing jobs, can impact ESTA eligibility after approval.

“ESTA approval isn’t a set-and-forget pass,” Christa warns. “If your answers to any eligibility questions change, you must reapply. Otherwise, you could be turned away at the airport.”

Can I sneak in remote work while visiting the U.S. on an ESTA? 💻

No. ESTA doesn’t allow any form of employment, including remote work for non-U.S. companies.

“The U.S. doesn’t have a digital nomad visa,” Christa explains. “If you’re working online during your 90-day visit, immigration officers may view that as unauthorized work.”

If you want to legally work abroad, consider destinations with proper digital nomad visas.

There’s no renewal process. When your ESTA expires, or if you get a new passport, you must start a new application from scratch.

Is ESTA the same as a visa?

Not quite. ESTA is a travel authorization for short visits (tourism, business, transit) under the Visa Waiver Program. It’s quicker and easier than a traditional visa, but it doesn’t replace one if your travel plans fall outside ESTA rules.

If you need a full visa instead, like a B1/B2, learn more about your options here.

What if my ESTA is denied?

You’ll need to apply for a traditional visa, like the B1/B2, at a U.S. embassy. While we don’t process these directly, we partner with Visaclick for a seamless handoff.

"Some travelers think ESTA is a guaranteed pass, but it’s not," says Christa. "Previous visa refusals, travel to certain countries, or inconsistent info can flag your application."
