Does anyone know the jurisprudence of citizenship? In the pre 14th amendment years, all people who were citizen of a state became citizens of the United States by virtue of being a citizen of a state. Does that still apply despite the 14th amendment's citizenship clause? (The 14th amendment says, "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside.") Also I was wondering if a state can still declare a person to be a citizen of the state because Article I Sec.8 says gives the power to Congress "To establish an uniform Rule of Naturalization...throughout the United States;" As you can see the Constitution says that Congress can make uniform rules pertaining to naturalization, but if those rules are met, it doesn't forbid any state from naturalizing such a person. Interestingly enough, it thus seems that the Constitution does not give any right to Congress to declare citizens, but only to make uniform rules which the states follow when declaring others citizens. Any thoughts?
