Irish Citizenship by Descent / Foreign Births Registration
Ireland
Irish citizenship by descent allows individuals with an Irish-born parent or grandparent to register as Irish citizens through the Foreign Births Register, administered by the Department of Foreign Affairs. This is not an application for naturalization but a registration of an existing entitlement. Once registered, the individual is a full Irish citizen with all rights, including the right to live and work in the EU and obtain an Irish (EU) passport. The generational limit is strict: grandchildren of Irish citizens may register, but great-grandchildren cannot unless a parent registered in the Foreign Births Register before the applicant's birth. Processing times have increased significantly due to high demand, particularly from the United Kingdom following Brexit.
