Irish Citizenship Applications

Irish Citizenship by Descent & Foreign Birth Registration

Under Irish law any person with an Irish born parent or grandparent is entitled to full Irish (and EU) citizenship. This is referred to as Irish Citizenship by Descent. Irish Citizenship by Descent is not granted automatically, you must first go through an extensive application process to have your name registered in the Foreign Births Register, which then entitles you to Irish citizenship and an Irish passport.
