I have never seen ANYTHING that stipulates in LAW that the father must be a citizen at the time of birth to establish "Natural Born Citizenship" status.

I think that must have something to do with that fact that there is no law that states that a person born in the US must have two US citizen parents in order to be a natural born citizen.

I imagine that is is due to the fact that this is not a matter of statute law at all. It is a matter of Constitutional definition, and Constitutional words are not defined by statute. If they could be, we could do away with the Amendment process and just redefine select words and phrases any time we wanted to mean whatever we decided they should mean. That is decidedly NOT the case.
