If one of your parents was a US citizen, which is the case in all four examples, you are a natural born US citizen.
That simply isn't true, and the statute says no such thing. If you have only one citizen parent and are born overseas, there are a variety of other requirements laid out in the statute if you are to be considered to be a citizen at birth. That being said, I 100% agree with the idea that "natural born citizen = citizen at birth, for all the reasons that have been stated exhaustively here for more than a decade.
And how do you jive this notion with the conditions with which some citizens have to comply to retain citizenship?
(Residency requirements and so forth.)
I know I could have gone overseas and never came back, and I would still have US Citizenship, but these "statute" based citizens would get their citizenship revoked for doing that.
Seems to me conditional citizenship isn't natural citizenship.
We don’t know who his parents are.
