The travel documents required to enter Ireland in 2026 depend on your nationality and the purpose of your visit. For U.S., Canadian, UK, and EU citizens, a valid passport is typically all that is required for a stay of up to 90 days for tourism or business. However, citizens of "Visa Required" countries (such as India or China) must apply for a visa via the AVATS online system at least eight weeks in advance. Key requirements for a 2026 Irish visa include a passport valid for six months beyond your departure, proof of sufficient funds (typically six months of bank statements), and proof of private medical insurance. Following Brexit, the Common Travel Area still allows British and Irish citizens to travel between the two countries without a passport, though some form of photo ID is recommended for airline security. For all non-EU visitors, you must be prepared to show "Proof of Return" and evidence of accommodation to the immigration officer upon arrival, even if you do not require a pre-entry visa to land in Dublin or Shannon.
