"State citizens, Extradition
The Citizens of each State shall be entitled to all Privileges and Immunities of Citizens in the several States."
It can be argued that a "US Citizen" is an invention of the 14th Amendment:
"Amendment 14 - Citizenship Rights. Ratified 7/9/1868.
1. All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside."
Note that even this language acknowleges the state citizen.
You continue to confuse the status of “citizen” with the status of “natural born citizen.”
