How does the Common Travel Area affect immigration to Ireland?

The Common Travel Area (CTA) is a longstanding arrangement between Ireland, the United Kingdom, the Channel Islands, and the Isle of Man that allows for free movement of citizens between these jurisdictions. Under the CTA, Irish and British citizens can travel freely between the two countries without a passport (though carrying identification is recommended) and can reside and work in either country without immigration permission.

The CTA predates both countries' membership of the EU and was preserved following Brexit through bilateral agreements. Irish and British citizens continue to enjoy reciprocal rights including the right to work, access healthcare, vote in certain elections, and access social welfare in each other's country.

However, the CTA applies only to Irish and British citizens. Non-EEA nationals and other foreign nationals do not have CTA rights and must comply with the immigration rules of each country separately. A person legally resident in the UK is not automatically entitled to enter or reside in Ireland, and vice versa. There are no routine immigration controls on the land border between Ireland and Northern Ireland, but immigration checks may be carried out at ports and airports, and within the State.

Non-EEA nationals travelling between Ireland and the UK should ensure they hold the correct visa or permission for each country. A UK visa does not grant entry to Ireland (as Ireland is not part of the Schengen area or the UK immigration system).
