Rules of naturalization means ALL RULES - including those who do need to be naturalized and those that don’t (natural born citizens). The first expression of that authority was the Naturalization Act of 1790 in which you will find the exact term “natural born citizen”.
Naturalization rules apply to natural born Citizens?
You've got some twisted logic there.
Is the Nat Act of 1790 still in force?
Why did they repeal it 5 years later with that languange removed, if they had the authority?
Don’t forget the part about “being a free white person” - that must still be in force too, right?
