 Such people become Irish citizens from the date of registration, or for those registered on or before 30 June 1986, from their date of birth, or 17 July 1956 if they were born before that date.Once a person is on the foreign births registration certificate, any children they have who are born after this registration date are entitled to Irish citizenship by also registering on the Foreign Births Register (children born outside Ireland to Irish-citizen parents born outside Ireland do not become Irish citizens automatically).Thus, the Irish citizenship of future generations born abroad can be preserved as long as the youngest generation registers onto the Foreign Births Register before having any children.
