In depth
The Department of Foreign Affairs (DFA) is the Irish government ministry responsible for the Foreign Births Register (FBR), Irish consulates, and Irish foreign policy. The DFA processes FBR applications through its Citizenship Division.
For CBD cases, the DFA is the authority that grants (recognizes) Irish citizenship by descent. Once registered on the FBR, the applicant receives a Foreign Births Registration Certificate, which is the legal proof of Irish citizenship.
The DFA also issues Irish passports through the Passport Office in Dublin (and Belfast for Northern Ireland residents).
