A Plain Citizen. he is NOT natural born because his father was not a U.S. Citizen at the time of his birth.
That's not a type of citizen. The choices are naturalized or natural born.
So, you’re saying because the parent was a women she’s less than equal and doesn’t get to pass natural born to her children.
So based on your definition of NBC - born on US soil to TWO US citizens - a child born in the US of a single woman who is a US citizen would not be a "natural born citizen" if she got pregnant through a sperm bank?
So, if a "U.S. Citizen" father of a child should happen to die before said child is actually born, would that set of circumstances deprive said child of his "Natural Born Citizen" status? Does Vattel have anything to say about that?
Or if the citizen father should happen to have renounced his U.S. citizenship in the period of time between the conception and the birth of the child, what then?
I'm not myself fluent in French, so I'm relying on you to work through these intricacies.
