and the USSC turned down several cases
SCOTUS is off the rails. They hear cases they shouldn’t (usually for political reasons - poltics is something they’re not supposed to concern themsleves with) or they don’t hear cases they should for much the same reason.
Nevertheless, we have some guidance about somehing many are confused about. The Naturalization Act of 1790 helps passed three years after the Constitution was ratified with many of the same people involved acknowledges that, the children of citizens of the United States that may be born beyond Sea, or out of the limits of the United States may be NBCs under certain conditions.
Although the Act itself was replaced, the portion about birth outside the U.S. was not contravened in the new law and thus we have some insight into original constitutional understanding that at least the possibility existed that one may be foreign born and an NBC.
