Naturalization is the process by which an alien from one country becomes a citizen of another country. The naturalization process did not have to happen in one court, or in one location. It was not mandatory and not all immigrants became citizens, and not all completed the process once they started it. Naturalization Records are very important to your genealogical research but are often overlooked.
