Nonsense. Your talking about naturalization laws that applied to the states PRIOR to the adoption of the federal Constitution. I clearly was refering to "the United States."
Under the Articles of Confederation, anyone naturalized by one of the States became a naturalized citizen of the United States. States continued to naturalize citizens of the United States even after the ratification of the Constitution, until Congress passed the first federal naturalization law in 1790. Someone naturalized by, say, the State of Virginia in, say, December of 1789 was a citizen of the United States but not a Natural Born Citizen, and not eligible to be President.
