Dates indicate overall time span of discrete series of naturalization records.
There are gaps and incomplete files. Some records of naturalizations in Federal courts precede these dates and can occasionally be found among civil and criminal case records from the 19 th century. Other types of naturalization records also exist. These records are extremely complex and take much time for a researcher to examine in our textual research room. Consult with an archivist for assistance in arranging a future visit to view such original records.
