Michigan, State Archives, Naturalization Records, 1812-1993

What is in This Collection?

This collection contains an index to naturalization records for Michigan, for the years 1812 to 1985. Immigrants could naturalize in any court that performed naturalizations. That included city, county, state and federal courts. After 1906, federal courts naturalized many immigrants, however, other local courts continued to naturalize as late as 1985. Check all possible courts in the area your ancestor lived.

Begin by looking for naturalization records in the courts of the county or city where the immigrant lived. Look first for the petition (second papers), because they are usually easier to find in courts near where the immigrant eventually settled. After 1906, the declaration can be filed with the petition as the immigrant was required to submit a copy when he submitted the petition.
