How long does an ESTA last?

An approved ESTA is generally valid for two years from the date of authorization or until your passport expires, whichever comes first. During this period, you can make multiple trips to the USA, each up to 90 days.

Can I work in the USA with an ESTA?

No, an ESTA is for tourism or specific short business activities only. It does not permit employment, study for credit, or long-term stays in the USA. For these purposes, a specific visa is required.

What if my ESTA application is denied?

If your ESTA application is denied, you are not eligible to travel under the Visa Waiver Program. In this situation, you will need to apply for a non-immigrant visa at a U.S. Embassy or Consulate before you can travel to the USA.

Do children need an ESTA?

Yes, all travellers, including infants and children, regardless of age, must have their own valid passport and an approved ESTA or visa to enter the United States under the VWP.

What is the passport validity requirement for USA travel?

For most VWP travellers, your passport should be valid for at least six months beyond your intended period of stay in the United States. Your passport must also be an e-Passport with an integrated electronic chip.

Is travel insurance required?

While not legally required for entry, travel insurance is highly recommended for all visitors to the USA. U.S. healthcare costs can be extremely high, and insurance can cover unexpected medical emergencies, trip cancellations, or luggage issues.

Deep breath. Here's the answer.

Irish citizens, as EU citizens, are eligible for the Visa Waiver Program (VWP), which allows for visa-free travel to the USA for tourism or business for up to 90 days. Instead of a visa, you must apply for an Electronic System for Travel Authorization (ESTA) online before your trip. An approved ESTA is mandatory for boarding a flight or ship to the USA under the VWP.

You may need a visa if…

An approved ESTA does not guarantee entry; ultimate decision rests with U.S. Customs and Border Protection.
If you have visited certain countries (e.g., Cuba, Iran, Iraq, Sudan, Syria, Libya, North Korea, Yemen) since March 2011, you may not be eligible for ESTA and might need a visa.
Dual nationals of VWP countries and certain other countries (e.g., Iran, Iraq, Sudan, Syria) may also be ineligible for ESTA.
Overstaying your ESTA or violating its terms can result in future travel restrictions.
ESTA is for tourism/business only; other purposes (e.g., study, employment, long-term stay) require a visa.

Print a copy of your approved ESTA or save it electronically.
