My younger son was born in Spain, of two American parents. His original birth certificate is Spanish. He also has a US birth certificate issued by the State Department.

I think that he is natural born, because of his parentage.

He's natural born because he is entitled to citizenship due to the circumstances of his birth.

Unlike, say Kissinger, Schwarzenegger, or Granholm, each of whom was born foreign (German, Austrian, Canadian, respectively) and each of whom needed to be naturalized in order to acquire US citizenship. Thus, those three are not eligible.

Your son is eligible, as are Cruz, Jindal, Haley, Rubio, McCain, and Obama.

Your son was a US Citizen from the moment of birth according to US law. The specific law is the Immigration and Nationality Act section 301. The title of the chapter containing that section is Nationality at Birth and Collective Naturalization.

Your son is a US Citizen through "Collective Naturalization", and therefore a naturalized US citizen, and not 'natural born'.

[Nero Germanicus]

Here is the current law of the land that applies to the birth circumstance of your son:
“The following shall be nationals and citizens of the United States at birth:
(c) a person born outside of the United States and its outlying possessions of parents both of whom are citizens of the United States and one of whom has had a residence in the United States or one of its outlying possessions, prior to the birth of such person;”

The intent of the founders by the natural born Citizen requirement was to ensure that our presidents possess no other allegiances than to the USA. A child born of two USA citizens at high sea, in USA territories or even (for the most part)* if born while that child's parents were traveling in foreign lands is a citizen born with exclusive allegiance to the USA.

*Most countries do not make citizenship claims (that are recognized as legitimate by the USA) on the children of foreign travelers who happen to give birth on their soil while visiting on a traveler's visa. A thought experiment will test this: If such a young man (born to USA citizens on foreign soil, but raised in the USA) visits the land of his birth and is impressed against his will into their military, will the USA let this pass or will our government do everything within its power (including the use of force) to get him back?

Into which category would your son fall?
