Those born in the US are citizens not by a law or statute, but by 14th amendment. Hence natural born citizens.
Wrong, but nice try. Reach back tot he days of the founders and see what it was they were trying to acvoid in a POTUS ... divided loyalties. Having citizenship in two countries at birth is divided loyalties. If born on a ship at sea under no nation’s flag, what would determine if natural born or not? ... Both parents being American citizens would make the child a natural born citizen.
