Do I Need a Visa?

General Rules

If you’re a citizen of a foreign country, in most cases you’ll need a visa to enter the United States.

Ireland participates in the Visa Waiver Program (VWP), so most Irish citizens (and citizens of the 36 countries that also participate in the Visa Waiver Program) do not need a visa to enter the United States for a trip of less than 90 days for general business, tourism or transit. A valid machine-readable passport is required. Irish passports must be valid for at least the duration of the stay in the U.S.  Please note that all travelers including children, even infants need their own, individual machine-readable passport and visa, as applicable.  Follow link to Passport Requirements for Visa Free Travel to the United States for further information.

Travel on the VWP also requires that travelers must register with ESTA on-line at and receive approval.
