Dual citizenship?
Wouldn't that mean one would have to live in Ireland for a specific time, apply, and pass a citizenship test? Or have already been born there in which case you would have to had applied for USA citizenship? I do know if you were born on a US base in another country there are ways to get that country's citizenship in some cases. This smells like BS to me but I am not very knowledgeable about this area. Most likely 10 times more than the Dummy though.
For most countries, if one of your parents was a citizen, you are a citizen by birth there if you can prove your parentage, just like a child of an American citizen being born overseas...such a person can claim citizenship by birth location (In most countries) or citizenship in the proven parent's country. This is why all the Birther stuff about Obozo was a completely pointless diversion. Some countries require such a dual citizen child to make an election between the two when the age of majority is reached, many do not. I have no idea what the Irish Republic does on this, their national government is a peculiar mixture of moonbat, Irish cultural quirks, and a Brittonic love of confining and often quixotic regulations. Up until their tax reform, they also faced a demographic drain of young people seeking opportunities elsewhere (An eternal Irish issue, really), and any ease in their immigration laws probably dates to that era, though it is not so much the case anymore. Regardless, I am dubious about how much desire they'd have to bring in a person who would be completely dependent on their health system with no potential whatsoever of making a positive contribution to the society, by which I mean the daughter. I don't know what Mo's source of income is, though if her citizenship claim is honored in full I assume it's not going to be scrutinized. I don't know how their health care system works, but if it requires some lifetime qualification involving payment of Irish taxes, her eligibility to participate would clearly be a problem for her.
