Ireland citizenship through a great-grandparent
Great-grandparent claims work only if your parent was already on the Foreign Births Register before you were born. Without that, the line is closed — regardless of how Irish the family is.
Each generation must be FBR-registered before the next is born for citizenship to keep flowing.
Agencies marketing great-grandparent routes are called out by the community as high-cost, low-success.
Rare alternative: Irish "associations" naturalisation (ministerial discretion) — slow and discretionary.
Check whether your parent (or you) were registered on the FBR before the relevant births.
If the chain is broken, look at other ancestral lines or Irish residency routes.
