Rafael Sr was a Canadian citizen? That’s news to me.
Rafael Sr became a US citizen a few years ago. Up until that time, he was, from what I’ve read, a Cuban citizen.
Yes. It’s in his bio.
He became a Canadian citizen while in Canada. His wife did not. At the time under the then-current Canadian immigration law, Canadians could not hold dual-citizenship, so the implication is that Senior had to renounce his Cuban citizenship to acquire his Canadian citizenship.
Following that same pattern, when he became a US citizen, he renounced his Canadian citizenship.
