Naturalization Records

Naturalization is the act of granting the full legal rights and privileges possessed by native-born individuals to someone born in another country. Legal jurisdiction over naturalization has changed repeatedly since the colonial period and records documenting the process are found in various locations. The State Archives holds relatively few such records and inquiries usually result in referrals of researchers to other repositories. The tools below will help you determine where records of interest to you are likely to be found.
