The Constitution only mentions two subdivisions of citizen as well.
Of American citizens; one is either born a natural born citizen - or one must be “naturalized” into that state of natural allegiance that otherwise only circumstances of birth could impart.
The implication of the term “natural born” in the constitution is that regardless of where on Earth you might be born, you would automatically be an American citizen.
The only way that could be so is if both of your parents were citizens of the US.
Any other combination would leave your citizenship status in question.
And yet the bozos believe there is a mystical third type of citizenship...native born. Of course, ALL native born citizens are ALSO natural born citizens which brings us back to natural born and naturalized citizens. Only TWO categories. But that won't stop folks from conjuring up that mystical third type of citizenship which magically appeared in their imaginations from 2008 on.
