Dear Mr. Biafore,
Thank you for posting your request on History Hub!
Beginning on September 27, 1906, the responsibility for naturalization proceedings was transferred to the Federal courts. If a naturalization took place in a Federal court, naturalization indexes, declarations of intention (with any accompanying certificates of arrival), and petitions for naturalization will usually be in the custody of the National Archives facility serving the state in which the Federal court is located.
For access to the records of Federal courts in West Virginia, please contact the National Archives at Philadelphia (RE-PA) via email at firstname.lastname@example.org and request a search for Frank/Francesco Biafore’s naturalization records by including the name of petitioner (including known variants); date of birth; approximate date of entry to the US; approximate date of naturalization; where the individual was residing at the time of naturalization (city/county/state); and country of origin.
In most cases, the National Archives will not have a copy of the certificate of citizenship. Two copies of the certificate were created – one given to the petitioner as proof of citizenship, and one forwarded to the Immigration and Naturalization Service (INS).
Certificates of citizenship were issued by the Federal courts until October 1991 when INS took over responsibility for naturalization proceedings. All INS records are now overseen by the US Citizenship and Immigration Services (USCIS). USCIS maintains duplicate copies of court records (including the certificate of citizenship) created since September 27, 1906 and may be requested through the USCIS Genealogy Program.
We hope this is helpful. Best of luck with your family research!
