Ireland has a huge disaporia, if Ireland had the same rules as italy in allowing retropestive bloodline citizenship, you would easily have many times the population of Ireland having entitlement, that would be a serious concern as you would effectively have people in other countries having undue influence in irish affairs.FrozenTundra wrote: ↑Sun Aug 14, 2022 11:31 pmNo, your son would not be eligible for Irish citizenship since your Irish citizenship through FBR is not retroactive to your birth: you are only an Irish citizen from date printed on the FBR certificate onwards. Since your citizenship isn't retroactive, your son was not born to an Irish citizen and thus is ineligible for Irish citizenship by descent.
Fun aside: prior to 1986 Irish citizenship through FBR was indeed retroactive to the applicants birth and thus you used to be able to do what you are asking. You could in theory have multiple generations all apply at once for Irish citizenship through FBR since all of their citizenships would be back dated to their birth.
Another fun aside: my ex-girlfriend was able to obtain Italian citizenship through her great-grandfather. This is because the Italian government granted her father Italian citizenship by descent (through his grandfather) and then my ex-girlfriend was able to apply through her father even though she was an adult when he registered as an Italian citizen. This is because that Italian citizenship was backdated to his birth; Italy backdates all citizenships to birth. This is why you see 5th or 6th generation "Italians" in North and South America who have Italian passports but with no recent ancestor from Italy. Ireland does not do this and is not as generous.
To date the amount of FBR registered people since 1956 stands at around 250,000, most of whom did not register before the next generation being born, while that maybe significant in regards to Irelands population its a tiny number to the population of the UK and USA, and would not cause a "swamp" of the native population.
