“That is also true and granted is the correct word. They applied at the consulate or to the State Department and met the Naturalization Statute requirements in effect at the time of their birth and became citizens but ...are not NBC.”
As said before, there are only TWO legal status for Americans. Naturalized and NBC. Not three.
Now, if you get enough traction to get a Supreme Court ruling or written law that could change. But as of now that’s the situation, like it or not.
Have a nice day. You are right, two states. Anyone that is granted citizenship on the basis of Naturalazation statutes is naturalized. The citizenship from birth is a construct not part of the constitution.
