Cincinnati / Covington to Shannon (CVG–SNN) — Airlines, Schedules & Connections

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.
