Visa & Entry

US passport holders enter Ireland visa-free for up to 90 days. No advance application is needed. Ireland is an EU member but not in the Schengen area, so time spent in Ireland does not count against any Schengen 90-day limit. Passport must be valid for the duration of the stay (Ireland has no minimum validity requirement beyond the trip dates). At Dublin Airport (DUB), Shannon (SNN), or Cork (ORK), immigration stamps your passport and may ask about your accommodation and return plans.

Ireland is part of the Common Travel Area (CTA) with the United Kingdom, Jersey, Guernsey, and the Isle of Man. There are no routine immigration checks on travel between Ireland and the UK, but you still need valid identification. Northern Ireland (part of the UK) is freely accessible from the Republic with no border controls. The Wild Atlantic Way (2,500km coastal driving route) and the Ring of Kerry are among Europe's best road trips.

Direct flights from New York JFK to Dublin run about 6 hours 30 minutes on Aer Lingus, Delta, and United. Boston (BOS) to Dublin runs about 5 hours 30 minutes. Direct service also operates from Chicago, Newark, Philadelphia, Los Angeles, San Francisco, and Washington Dulles. Ireland uses the euro, trading at roughly $1.08 per EUR 1. The Leap Card works on Dublin Bus, Luas tram, and DART commuter rail at EUR 1.70 to EUR 3.30 per trip. The Airlink Express bus 747 runs from Dublin Airport to the city center in 30 minutes for EUR 8 ($8.65). Pub culture is part of daily life: a pint costs EUR 5.50 to EUR 7.50 ($5.95 to $8.10) depending on location.

Verify entry requirements with official sources before travel.
