Cuban citizens aren’t sovereigns like us citizens are- us sovereignty I believe trumps foreign sovereignty in cases like this I believe- I was responding to the person who made the point Cruz’s father wasn’t a citizen- it doesn’t matter if he wasn’t a citizen- Ted’s mother was- and by sovereign descent, that is all that matters- according to current rulings
I agree that Ted’s father’s citizenship is irrelevant for purposes of finding naturalized US citizenship. But it is relevant for finding whether Ted’s father could claim Cuban citizenship for Ted. He didn’t, but he could have. Ted lost his claim to Cuban citizenship maybe when his parents claimed US citizenship for him, and certainly when his father naturalized as a Canadian.
Cuba determines who will or will not be their citizens by the legal means of their own determination. If they have legally established that a child born outside Cuba to a Cuban parent is a Cuban citizen at birth, then that child is a Cuban citizen. Specific to Cruz, I believe that his father expatriated and that this means Cuba no longer had any legal basis to claim Ted Cruz as a citizen, even if the operation of their citizenship laws would normally have claimed such a child as a citizen. Others may disagree, obviously.
