Foreign BORN, yes. If you are NOT foreign born, you are a NBC. In order to know who needs naturalization, you MUST define what a citizen at birth is. The statute does that.
As John Jay wrote in a letter addressed to Washington in his role as President of the Constitutional Convention "Permit me to hint whether it would not be wise and seasonable to provide a strong check to the admission of foreigners into the administration of our national government ; and to declare expressly that the command in chief of the American army shall not be given to, nor devolve on any but a natural born citizen."
To quote from the excellent exposition to be found at www.thebirthers.org/USC/Vattel.html, "Jay not only knew of Vattel, as can be seen from his correspondence with James Madison in 1780 during treaty negotiations with Spain, but he was also a proponent of Vattel as well. "
If you are NOT foreign born, you are a NBC.

That has *not* been settled in SCOTUS case law. Especially with respect to dual citizenship - either British or Indonesian. I’m not sure if the SCOTUS will have the courage to touch this - so we’re just hurtling forward (as Obama and handlers would like) into uncharted territory - with the great arrogance of a WH involved in a cover-up.
Remind you of anything?
