Try Rogers v Bellei
We thus have an acknowledgment that our law in this area follows English concepts with an acceptance of the jus soli, that is, that the place of birth governs citizenship status except as modified by statute.Jus soli means "born on the soil" (usual diplomatic etc. exceptions) = natural born.

This Rogers case is about whether a foreign born child with one US citizen parent (the father) is a US citizen at birth. The case ruling has nothing to do with Barry's NBC status, given his claimed birth in HI. If Barry was born in Kenya, this case could possibly apply to Barry's citizenship, but Barry would not be NBC under MvH if born outside the US.

I like to cite Rogers v Bellei myself. It proves beyond a doubt that a "citizen at birth" is not the same thing as a "natural born citizen."
In any case, New York, California, et al have "modified the statute", so that place of birth doesn't apply to the children of transient aliens. Here is a copy of the New York law. (1845)
Now this seriously begs the question. How can someone be a "natural born citizen", if they are explicitly BANNED by State law from even being a citizen?
