Do I need a passport or visa to enter?
You will need your valid passport to enter Ireland, but you will not need a visa for tourist or business stays of up to three months. Visit the Embassy of Ireland website for the most current visa information. You may also contact the Irish Embassy at 2234 Massachusetts Avenue, NW, Washington, DC 20008, Tel: 1-202-462-3939, or the Irish consulate nearest you; these are located in Boston, Chicago, New York, San Francisco, and Atlanta.
Irish Immigration strictly enforces national immigration laws and regulations. You will be expected to present all documentation relating to the purpose of your trip to Ireland to the Irish Immigration officer upon your entry into Ireland. Irish Immigration may grant a stay of up to three months; however, they may grant a lesser period than three months depending on the documentation provided. In the past few years, an increased number of U.S. citizens have been refused entry or have been granted only a limited stay because they failed to comply with and/or satisfy Irish immigration laws. Some cases have also involved other EU states’ immigration authorities when U.S. citizens traveling from Ireland to another EU state have been deported back to Ireland due to visa-related matters.
