An ESTA is valid for two years from the date it is issued, but your passport must remain valid for the entire trip

An ESTA (Electronic System for Travel Authorization) lasts for two years from the date the Department of Homeland Security approves it. You can use it for multiple trips to the United States during those two years without reapplying — each entry is separate, and you do not need to request permission again between visits.

The catch is that your passport must be valid on the day you arrive in the United States. If your passport expires before your ESTA does, the ESTA becomes unusable. Many travelers renew their passport and then discover their old ESTA no longer works, because the ESTA is tied to the specific passport number it was issued under.

Each time you enter the United States on an ESTA, you are allowed to stay for up to 90 days. That 90-day clock resets with each new entry — it is not a total across all your trips during the two-year window.

Key Takeaways

  • An ESTA remains valid for two years from approval, but only if your passport stays valid for the entire period.
  • If you renew your passport before your ESTA expires, you must obtain a new ESTA tied to your new passport number.
  • You can make multiple trips to the United States during the two-year ESTA validity period without reapplying between visits.
  • Each entry to the United States allows you to stay for up to 90 days, and that limit resets with each new arrival.
  • An ESTA does not may provide entry — U.S. Customs and Border Protection can still deny admission even if your ESTA is valid.

What happens when your ESTA expires

When your two-year ESTA window closes, you cannot use it to enter the United States anymore. If you plan another trip after the expiration date, you must submit a new ESTA request and pay the fee again. The process takes the same amount of time as the first one — usually approved within minutes, though it can take up to 72 hours in some cases.

You will know your ESTA is about to expire because the approval notice you received includes the exact expiration date. The Department of Homeland Security does not send a reminder, so it is your responsibility to check before you book travel. If you arrive at the airport with an expired ESTA, you will not be allowed to board your flight to the United States.

Renewing your passport before your ESTA expires

If you renew your passport while your ESTA is still valid, your old ESTA becomes tied to your old passport and cannot be used with your new one. You must obtain a new ESTA under your new passport number, even though your original ESTA has not yet expired.

This is one of the most common sources of confusion. The ESTA system matches your passport number to your travel history, so the two must align. When you explore for the new ESTA, you will pay the fee again. Keep your old ESTA approval notice for your records, but do not attempt to use it with your new passport.

How to check your ESTA expiration date

You can look up your ESTA status and expiration date on the official ESTA website using your passport number and date of birth. This is the only way to confirm the exact date — your approval email may not be straightforward to find months or years later.

The lookup tool is free and takes less than a minute. If you cannot find your ESTA in the system, it either expired, was denied, or was never submitted. Do not assume it is still valid based on memory; check the official system before you book your flight.

ESTA validity and the 90-day stay limit are separate

The two-year ESTA validity period and the 90-day stay limit are not the same thing. Your ESTA allows you to attempt entry to the United States for two years. Once you arrive, U.S. Customs and Border Protection stamps your passport with a 90-day permission to stay. When those 90 days are up, you must leave the country.

If you want to stay longer than 90 days, you need a different visa — an ESTA does not extend beyond that limit. If you want to return after leaving, your ESTA can still be used for another trip within the two-year window, and you get another 90-day stay on that new arrival.

When you need a new ESTA before two years

You must obtain a new ESTA before the two-year mark expires if any of the following happens: your passport is renewed, your name changes legally, your gender marker changes, or you answer "yes" to any of the security questions on the process where you previously answered "no." Changes in citizenship or country of residence also require a new ESTA.

If you are unsure whether your situation requires a new process, the safest approach is to submit a new ESTA request. The fee is the same, and approval is usually fast. It is far cheaper and simpler than being denied boarding because your ESTA is no longer valid.

What to do if your ESTA expires while you are in the United States

If you are already in the United States when your ESTA expires, it does not affect your stay. Your permission to remain is based on the 90-day stamp in your passport, not on the ESTA itself. The ESTA only controls whether you can enter the country; once you are inside, the expiration does not matter.

However, if you leave the United States and want to return before your ESTA expires, you can use the same ESTA. If your ESTA has expired by the time you want to return, you will need a new one before you can board your flight back.

Frequently Asked Questions

Can I extend my ESTA for another two years without reapplying?

No. When your ESTA expires, you must submit a new process and pay the fee again. There is no extension option — you either reapply or you cannot travel to the United States on an ESTA.

What if I renew my passport in the middle of my ESTA validity period?

Your old ESTA becomes invalid because it is tied to your old passport number. You must obtain a new ESTA linked to your new passport number before you travel. The new ESTA will have its own two-year validity period starting from the approval date.

Do I need a new ESTA if I change my name after marriage?

Yes. A legal name change requires a new ESTA process. You will also need to renew your passport to reflect the name change, which means your old ESTA is no longer usable anyway. Submit the new ESTA under your new name and new passport number.

Can I use my ESTA if I arrive in the United States after it expires?

No. You must have a valid ESTA on the day you arrive. If your ESTA has expired, you will be denied boarding at your departure airport. Check the expiration date before you book your flight, not at the gate.

If I leave the U.S. before my 90 days are up, can I come back on the same ESTA?

Yes, as long as your ESTA has not expired. Each entry to the United States resets your 90-day clock. You can make multiple trips during the two-year ESTA validity period, and each trip gives you a fresh 90 days.
