Citizen

A citizen is a native or naturalized person who owes allegiance to a government and is entitled to protection from it. There are different types of citizens, including U.S. citizens and nationals, which have distinct legal implications. 

There are two types of citizens:

• One who owes allegiance to, is subject to, and is a vassal to a government or sovereign.
• One who is a member of a self-governing state, that as a body is the final governing authority of a government limited to delegated powers and authority by members of the
  people.

This distinction being made between in both Black’s Law Dictionary(Legal) and Merriam-Webster Dictionary(Common Speak). There’s a “citizen” and a “citizen subject”. A citizen subject is a vassal to the government/sovereign, owing total faith and obedience, but with a citizen (member of a people/state) the roles are reversed and the government is controlled and limited by the citizens of the state for their purposes.

Congress acknowledges two distinct political statuses in our nation, citizens of the states and citizens of the United States, going all the way back to 1872.
