Good news!
I just found conflicting information that may make your original post correct and mine wrong or at least open to question.
From the US Code, Title 8, Section 1401:
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;
That looks to me like if military parents stationed overseas have ever had a US residence, their offspring are Citizens of the United States at birth.
I know. Your posted excerpted law, which references the 14th amendment, concerns children of non US citizens born on US facilities outside the US. It does not apply to children born of US citizens....
Still nice info... thanks for the effort and correction!
See what kind of problems you run into when you rely on manmade law to determine what is "natural"?
Vattel had this covered 250 years ago.
That looks to me like if military parents stationed overseas have ever had a US residence, their offspring are Citizens of the United States at birth.
And beyond that, they are "natural" citizens at birth.
