All the important questions about your ESTA for the USA – explained simply.
1. How long is the ESTA valid for the USA?
The ESTA is generally valid for up to 2 years or until your passport expires – whichever comes first. If you receive a new passport, you will need a new ESTA. Learn more in our guide on ESTA validity.
2. What is the difference between an ESTA and a visa?
The ESTA is an electronic travel authorization for short tourist or business stays for citizens of Visa Waiver Program countries. A visa is a more involved process for longer stays, work, or study. Details in our article ESTA or Visa?
3. How long does it take to process an ESTA application?
Most applications are approved within a few hours, though in individual cases it can take up to 72 hours. We recommend applying at least 72 hours before departure. Learn more in our article on ESTA processing time.
4. What if my ESTA is denied?
A denial means you cannot enter under the Visa Waiver Program. In that case, a regular visa from the U.S. embassy is usually required. Full details in our article ESTA denied: reasons and next steps.
5. Do children also need an ESTA to enter the USA?
Yes, every person – regardless of age, including infants – needs their own individual ESTA. A parent completes the form on their behalf. Learn more in our article ESTA for the whole family.
6. How many times can I enter the USA with one ESTA?
Within its validity period, you may enter as often as you like, provided each individual stay does not exceed 90 days and continues to serve tourist or business purposes.
7. Do I also need an ESTA for a flight transit through the USA?
Yes, as soon as you pass through U.S. border control during a layover, you need a valid ESTA – even if the USA is only a stopover. Details in our article ESTA for transit and layovers.
8. Do I need to renew my passport if it expires during my ESTA’s validity?
Yes. The ESTA is permanently linked to your passport number. If your passport expires, your ESTA also becomes invalid and must be re-applied for with the new passport.
9. Can I still change my ESTA details after submitting my application?
A later change is only possible to a limited extent. For major changes (e.g. a new passport), a new application is usually required. Please review your details especially carefully before submitting – tips in our article on the most common mistakes.
