What you're describing are not natural born citizens. A natural born citizen wouldn't need a third party to sue a state for custody to keep the child in the United States. The fact that these people have to do this actually works to reinforce the point of the thread.
The children born within the territorial limits of the U.S. (with very limited exceptions of children of diplomatic personnel)are natural born citizens. The situation I am describing is NOT suing a state for custody. The state is not a party to the action. These are guardianship or conservatorship documents which are filed with the courts to ensure their enforceability and legitimacy for 3rd parties, such as schools. This is required for any child who is being cared for by a non-parent, no matter the situation. The theory being espoused on this thread that if a parent is deported, then their natural born citizen child must leave with them, is just flat out false.
It’s hard to reason with these wrongheaded knuckleheads after they get shown hard evidence that being born in the US does not necessarily make one a natural born citizen or even a US citizen. See post 188.
