And so 8 USC yes, 8 USC does not redefine ‘natural born’, the problem is, the ‘at birth’ after 1401(a) where the statutes are clear, ‘at birth’ is retroactive upon the parents seeking, filing and receiving it for their child and even then, there are additional requirements the child must fulfill for that citizenship to be perfected. A ‘natural’ born person's citizenship is perfected the moment they are born without the aid of any statute, even without the aid of a birth certificate.
Again, anyone whose citizenship relies on anything past 8 USC, Sec 1401(a), is a naturalized citizen because the US does not have authority to govern the nationality of those born in a foreign country while that person is living in the foreign country of their birth. Justice Scalia covered this quite extensively in one of his lectures last year, how US law has no authority outside the jurisdiction of the US.
There, fixed it.
