I am pretty sure the founding fathers did not mean a person born on foreign soil to a foreign citizen father and an American citizen mother when that put the Natural Born Citizen (NBC) clause into our Constitution. IMHO there a three types of citizens.
NBC Two American citizen parents born on US soil (acceptations for Military and Diplomats)
Citizen at birth Parents are a married couple with one parent a US Citizen. Or mother is a US citizen.
Naturalized Citizen.
I know born on US soil gives citizenship at birth but I think that needs to be changed pronto. I also do not think that was the intent of the 14th
