> sovereign citizen there is you problem. no such thing on any code. "state citizen" was recognized for some time after the civil war. you can find the distinction between citizen of the united states and a state citizen in the slaughterhouse cases, plessy vs ferguson and a bunch more. the 14th amendment gave the "freed" slaves any constitutional rights. it made them citizens of the united states aka citizens of the federal government in washington dc. that is how the separate but equal jim crow laws were seen as constitutional. they did not have the constitutional protection that state citizens had. all political rights came from being a citizen of one of the several states. the current term for state citizen status is in the immigration act of 1940... it is simply "national." if you are a citizen of the united states and not a national aka citizen of the united states of america you are "subject" (see the 14th amendment) to the laws of dc. you are property. you are a serf. doubt it? which system had birthright citizenship? the feudal system. a child born to serfs was the property of the lord of the manor.  so in short as a citizen of the united states you are a serf and have no right to travel. you are subject to extra constitutional traffic regulations.
