Do not start in the wrong process.
The Irish government distinguishes the parent-born route from the grandparent route. A parent born on the island of Ireland can make the child an Irish citizen from birth, while a grandparent-based claimant generally becomes a citizen through registration.
The passport application must still prove identity, the parent-child link, and the Irish-born parent’s civil record.

Questions to resolve before you act
Do I need Foreign Birth Registration if my parent was born in Ireland?
The Department of Foreign Affairs says a person born abroad to a parent born on the island of Ireland is already an Irish citizen and does not use FBR to become one.
