The 1910 federal census has iformation on year of immigration nautralization status and the 1900 census has yr on naturalization, immigration and lenght of time in USA. Then once you have that you can figure out where they might have been at that time. Before about 1900 most declarations of intent were filed with the county courthouses. After1900 or so it was probably with the federal court having jursidiction for that area. Good Luck! Rob
