Naturalization records in Minnesota made before 1906 have no general index, although individual volumes from some courts may be indexed. Applications for citizenship are essential records to search in a state with so many immigrants. Even if an immigrant ancestor did not complete the process and become a citizen, he or she may have filed an application. These application records still exist and can be very helpful. | Naturalization records in Minnesota made before 1906 have no general index, although individual volumes from some courts may be indexed.
