Dear Ms. Benedict,
Thank you for posting your request on History Hub!
To request a copy of his Petition of Naturalization, we suggest that you contact the National Archives at Chicago (RM-CH) via email at firstname.lastname@example.org. Please provide the full name, date of naturalization, location of court, and certificate number in order for RM-CH to conduct a search of their naturalization holdings.
We hope this is helpful. Best of luck with your research!
