I would say the answer depends on how technical we're being.
A citizen of the United States is a legal resident who has been processed by the government as being a member of the United States.
A denizen of the United States is simply someone that lives there.
Technically speaking, one could never be, for example, a citizen of the Earth -- but we're all denizens of the Earth.
