Not every traveler to the United States needs an ESTA — and some who think they are exempt actually do need one. Knowing whether the rule applies to you is the first step in planning any US trip, because applying when you do not need to wastes money, and assuming you are exempt when you are not can get you turned away at check-in. Here is exactly who needs an ESTA in 2026, and who does not.
TL;DR
- You need an ESTA if you are a citizen of a Visa Waiver Program country flying or sailing to the US for up to 90 days.
- It applies to tourism, business, and transit through the US.
- Children and infants need their own ESTA — there is no family exemption.
- You do NOT need an ESTA if you hold a valid US visa or are a US/Canadian citizen or green-card holder.
- Some VWP travelers are barred from the program and must get a visa instead.
Who needs an ESTA
You need an ESTA if all of the following are true: you are a citizen or eligible national of a Visa Waiver Program country; you are traveling to the United States for 90 days or less; your purpose is tourism, business, or transit; and you are arriving by air or sea on an approved carrier. The full list of eligible nationalities is in our guide to VWP countries eligible for an ESTA, and country-specific instructions are available for travelers such as UK citizens, German citizens, and Japanese citizens.
Children, infants, and families
There is a common myth that children are covered by a parent’s ESTA. They are not. Every traveler, regardless of age, needs their own ESTA tied to their own passport — including newborns. Our guides on ESTA for families and children, minors and travel consent letters, and infants and newborns explain the details. Families can submit everyone in a single session using the family group application, but each person still receives a separate authorization.
⚠️ Every traveler needs their own ESTA
There is no family or group exemption. Infants, children, and adults each require an individual ESTA linked to their own passport. Do not assume a child is covered under a parent’s approval.
Who does NOT need an ESTA
Several groups are exempt. You do not need an ESTA if you already hold a valid US visa (such as a B1/B2 visitor visa) — in that case you travel on the visa, as explained in our ESTA vs B1/B2 visa guide. US citizens, lawful permanent residents (green-card holders), and most Canadian citizens do not need an ESTA either. And travelers from countries that are not in the Visa Waiver Program cannot use an ESTA at all — they must apply for a visa instead, a distinction covered in our ESTA vs US visa overview.
Quick Facts
| Needs an ESTA | VWP-country citizens, ≤90 days, air/sea, tourism/business/transit |
| Children | Yes — every traveler needs their own |
| Visa holders | No — travel on the valid US visa |
| US/Canadian citizens | No |
| Green-card holders | No |
| Non-VWP nationals | Cannot use ESTA — need a visa |
VWP travelers who are barred and must get a visa
Some people from VWP countries are nonetheless ineligible for the ESTA and must apply for a visa. This includes travelers who have visited certain restricted countries — see our guide to the restricted-country rules and the separate Cuba travel restriction — as well as some travelers with certain criminal histories, covered in our criminal record disclosure guide. If any of these apply, the ESTA will likely be refused, and you should plan for a visa from the outset.
Land border crossings
The ESTA requirement applies to arrivals by air and sea. Travelers entering the US by land from Canada or Mexico under the VWP follow slightly different procedures — our guide to entering the US by land explains when an ESTA is and is not required at land ports.
How to confirm whether you need an ESTA
- Check whether your nationality is on the Visa Waiver Program country list.
- Confirm your trip is 90 days or less and for tourism, business, or transit.
- Confirm you are arriving by air or sea on an approved carrier.
- Check whether you already hold a valid US visa — if so, you travel on the visa instead.
- Check the restricted-country and criminal-history rules that can bar you from the VWP.
- If you need an ESTA, apply early at the official CBP portal; if you are barred, apply for a visa instead.
Transit and connecting flights
A point that surprises many travelers is that you generally need an ESTA even if you are only changing planes in the US on your way somewhere else. The US does not have a separate airside transit zone the way some countries do, so transit passengers usually clear US immigration and therefore need authorization. Our guide to ESTA airport transit and layover rules explains the specifics, and the CBP ESTA pages confirm that transit under the VWP still requires an approved ESTA.
Cruise passengers and sea arrivals
Arriving by sea — including on many cruises that call at US ports — also triggers the ESTA requirement for VWP travelers. The rules depend on the type of voyage, especially for closed-loop cruises that begin and end at the same US port. Our cruise passenger guide and closed-loop cruise rules cover these cases so cruise travelers do not get caught out at embarkation.
What happens if you apply when you did not need to
If you already hold a valid US visa and mistakenly apply for an ESTA, you have simply paid the USD 40 fee unnecessarily — you would still travel on your visa. Conversely, assuming you are exempt when you are not is far more disruptive: airlines will refuse to board you without a valid authorization. When in doubt, check the Department of State VWP page and our eligible country list before deciding, and apply if there is any uncertainty about your status.
Frequently asked questions
Do children and babies need their own ESTA?
Yes. Every traveler needs an individual ESTA tied to their own passport, regardless of age — there is no family exemption.
I have a valid US visa — do I also need an ESTA?
No. If you hold a valid US visa, you travel on the visa and do not need an ESTA.
Do I need an ESTA to transit through a US airport?
Usually yes. The US has no separate airside transit zone, so VWP travelers connecting through the US normally need an approved ESTA.
Can a non-VWP citizen use an ESTA?
No. The ESTA is only available to citizens of Visa Waiver Program countries. Everyone else must apply for a visa.
Common eligibility edge cases
Beyond the clear-cut categories, a number of edge cases trip travelers up. Dual nationals should apply with the passport of a VWP country if they hold one, but dual nationals of certain restricted countries may be barred from the program regardless of their second nationality — our restricted-country rules guide covers this carefully. Travelers who have previously been denied a US visa or removed from the US may also be ineligible for the VWP and should seek a visa instead. And anyone unsure whether a past arrest or caution affects their eligibility should read our criminal record disclosure guide before applying, because answering the eligibility questions incorrectly can cause lasting problems.
If after all of this you are still uncertain, the safest approach is to verify against the official Department of State Visa Waiver Program page and, where eligibility is genuinely unclear, to consult the relevant US embassy. For the great majority of travelers, though, the answer is simple: a short-stay visitor from a VWP country needs an ESTA, applies once through the official CBP portal, and is approved within hours. Our first-time application guide walks you through every field if this is your first time.
If your circumstances are unusual or change between trips, treat each new journey as a fresh eligibility check rather than assuming last year’s answer still holds. Nationality, visa status, recent travel, and personal details can all shift the answer, and the cost of checking is minutes while the cost of getting it wrong is a refused boarding. A quick review against the official rules before every trip keeps you on the right side of the requirement.
Bottom line
If you are a Visa Waiver Program citizen taking a short trip to the US by air or sea, you almost certainly need an ESTA — and so does every member of your family, no matter how young. If you hold a valid US visa, are a US/Canadian citizen or green-card holder, or come from a non-VWP country, the ESTA either does not apply or is not an option. When in doubt, start with our ESTA requirements guide and the eligible country list, then apply through the official CBP ESTA system.
