I cannot find the date of their naturalization. If you’re born in the United States to people legally allowed to be here then you’re a citizen whether you like it or not. (not getting into illegals’ anchor baby thing)
There have been cases of people born here, move back home as kids and don’t return. Then years later they come back for vacation and are arrested for failure to file taxes with the IRS. They either forgot or didn’t know to renounce their citizenship.
So yes our government considers them citizens.
The requirement for the President is not just citizenship.
