Citizenship states refers to the citizenship one enjoys in the given state for which they live and work. Citizenship in one of the many states is frequently considered to make somebody a United States citizen, though they would have to go through the process if necessary. In an American court, citizenship in a state is considered to be different and separate than United States citizenship. A person is subject to the jurisdiction of a state simply by being physically present in that state. Whether a person is a citizen of the United States, foreign national, corporation or legal entity, they are subject to the laws of the state for which they reside and the federal laws that apply to that state.
