California and Texas are sovereign states, and becoming a citizen of California is really just a matter of moving there. Acts and corporations of Texas are recognized as "foreign" in California. Citizens of California have to swear a loyalty oath to the state to work for it, and all able-bodied male citizens of California are members of the unorganized militia and are subject to the state code of military justice. Treason against California is punishable by death, as is treason against Texas (apart from treason against the US). Per the Tenth Amendment, the federal government has only the sovereignty granted to it by the states via the Constitution. As a country, you can move almost anywhere in the US and have full citizenship rights. (Note that Puerto Rico, American Samoa, etc are not part of the US, and you don't get automatic rights when you move there. American Somoans are not even US citizens by birth, for example, because it's not part of the US. Palmyra Atoll and DC are the only part of the US not part of a state, and residents are not citizens of a state and don't have full US citizenship rights.)
