Dear Ms. Rivera,
Thank you for posting your request on History Hub!
Since your request was completed through the USCIS Genealogy Program, the record received was a Certificate File (C-File). Per USCIS, the Genealogy Program cannot provide certified copies, a record request can provide a photocopy of a naturalization record only. The National Archives cannot certify records that are not in our custody.
The Embassy of Italy in Washington, D.C., has advised the USCIS that applicants for dual citizenship are not required to provide certified copies of naturalization certificates obtained from USCIS. Instead, you must present the photocopy of the naturalization certificate along with the USCIS Genealogy Program response letter and mailing envelope.
We hope this is helpful.
