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.

I think the courts have weighed in on this stating essentially that a child born to a US citizen- even those born on foreign soil, are the children of a sovereign us citizen-

According to current cases, He wasn’t given citizenship by claim but rather by descent-
