You are absolutely right. However, what we are debating here is the special designation that becoming POTUS carries with it, that being the term “natural born citizen” but many do not make the distinction. Some say your grandchild could be president and others do not.
Marcella, I do now see you were commenting on the Vietnam Nam children, apologies if I interrupted!
Grandson could be president but he would have to give up his British citizenship as it is required for the candidate to have only ONE allegiance to a country.
Cruz was also a Canadian citizen, but he gave up that citizenship so he has only one allegiance to a country.
