Out of my tree on Romney or Rubio?
Just curious which limb I’ve jumped out of!
A 2011 Congressional Research Service report stated
The weight of legal and historical authority indicates that the term natural born citizen would mean a person who is entitled to U.S. citizenship by birth or at birth, either by being born in the United States and under its jurisdiction, even those born to alien parents; by being born abroad to U.S. citizen-parents; or by being born in other situations meeting legal requirements for U.S. citizenship at birth. Such term, however, would not include a person who was not a U.S. citizen by birth or at birth, and who was thus born an alien required to go through the legal process of naturalization to become a U.S. citizen.[1]
