Since the Deputy has not provided details of the particular case, I can only set out the position generally. In accordance with the Irish Nationality and Citizenship Act, 2004, the citizenship entitlement of every person born on the island of Ireland on or after 1 January, 2005 is governed by the citizenship of the person's parents at the time of the person's birth or the residency history of one of the parents prior to the birth. Babies born on the island of Ireland on or before 31 December, 2004, are entitled to Irish Citizenship.
Babies born on the island of Ireland on or after 1 January, 2005, are entitled to Irish Citizenship if one of their parents is an Irish citizen, or if one of their parents is a non-national legally resident in Ireland for three out of the four years immediately prior to their birth.
Babies born after 1 January, 2005 whose parents do not have the required residency at the time of their birth can apply for Citizenship for their child when the child has five years reckonable residence.
