Borders

Ireland is an Island nation with a unique border context. It shares a land border with Northern Ireland, which is part of the United Kingdom. Ireland and the UK operate a longstanding Common Travel Area (CTA), which allows Irish and British citizens to move freely between both jurisdictions without routine immigration controls.

At the same time, Ireland maintains its own immigration system and controls at its external borders, including airports and seaports, to manage entry to the State.

Frontline immigration functions at Ireland’s borders are primarily carried out by the Garda National Immigration Bureau (GNIB), including removals, detentions and related investigations. At Dublin Airport, however, frontline immigration control is the responsibility of the Border Management Unit (BMU) of the Department of Justice, Home Affairs and Migration.

All passengers arriving in Ireland are subject to immigration control. Under the Immigration Act 2004, individuals must present valid identification, and where required, a visa or employment permission. Immigration officers may examine documents and ask questions to confirm a person’s identity and purpose of travel. Where an officer is not satisfied, they may refuse permission to enter the State.

Automated eGates are available at Dublin Airport for eligible passengers, including those from the EU, EEA, Switzerland and the UK. These provide a self-service option to clear immigration control.
