Naturalisation Proof:
How to Find Your Ancestor's Records

Why naturalization records matter for Italian citizenship

The naturalization date is the single most important document in determining whether your Italian citizenship chain is intact. Here's why:

If your ancestor naturalized before your applicant ancestor was born, your applicant ancestor never had Italian citizenship to inherit. If your ancestor naturalized after your applicant ancestor was born and that child was over 21 (or the naturalization was after August 15, 1992), the citizenship chain is preserved.

The exact date matters. A difference of weeks or months can determine eligibility.

Example: Giovanni is Italian. He immigrates to America. His son Salvatore is born on June 15, 1920. Giovanni naturalizes on July 1, 1920 — just two weeks after Salvatore's birth. Because Salvatore was born before Giovanni naturalized, Salvatore has Italian citizenship. However, if Giovanni had naturalized on June 1, 1920 — before Salvatore's birth — Salvatore would have no Italian citizenship claim.

USCIS naturalization records (US, 1906–present)

The US Citizenship and Immigration Services (USCIS) maintains naturalization records for all naturalization events since 1906.

How to request USCIS records:

• Online search (limited): Visit genealogy.uscis.gov and search for your ancestor by name. This database has digitized records but is not comprehensive; many records are not yet online.
• FOIA request: Submit a Freedom of Information Act request to USCIS with your ancestor's name, approximate naturalization date, state, and any additional identifying information (birthplace, spouse name, etc.).
• By mail: Send your FOIA request to USCIS FOIA Office. Include a check if copying fees are required.
• Online FOIA submission: Some USCIS field offices accept online FOIA requests; check the USCIS website for your regional office.

What to expect:

• Processing time: 4–8 weeks (can be longer if backlogs exist)
• Cost: Usually free; copying fees may apply ($0.25 per page or flat fee)
• What you receive: A certified copy of the naturalization certificate or naturalization record, showing the date of naturalization, location, and applicant's information

The N-400 form and naturalization documents:

If your ancestor naturalized after 1906, an N-400 (Application for Naturalization) form exists. This form contains valuable information including the applicant's birthplace, arrival date in the US, and naturalization date. USCIS can provide the N-400 or a summary document.

NARA naturalization records (US, pre-1906 and historical)

The National Archives and Records Administration (NARA) holds naturalization records for all events before 1906 and also archives historical records from various courts and federal agencies.

How to request NARA records:

• Online search: Visit catalog.archives.gov and search for your ancestor's name. Some collections are fully digitized; others are not.
• Regional offices: NARA has regional branches across the US. You can visit in person to research or request copies.
• By mail or phone: Contact NARA directly with your ancestor's information. Research requests typically take 4–12 weeks.
• In-person research: If you visit a NARA location in person, research is often faster (same-day or next-day access to records).

What to expect:

• Processing time: 4–12 weeks (longer for complex or damaged records)
• Cost: Research fees typically $10–$50; copying is extra at standard rates
• What you receive: Copies of court naturalization records, naturalization petitions, or other historical documents proving citizenship acquisition

Certificate of Non-Existence (CONE) — when records are missing

If your ancestor's naturalization record cannot be found in USCIS or NARA databases, you can request a Certificate of Non-Existence (CONE). This is an official certification stating that no record of naturalization was found.

Why this matters:

If no naturalization record exists, it suggests your ancestor did not naturalize and retained Italian citizenship. A CONE can sometimes be accepted by consulates as evidence of non-naturalization, preserving the citizenship chain.

How to request a CONE:

• USCIS: Submit a FOIA request specifying that you are requesting a Certificate of Non-Existence. The request should be detailed with all identifying information.
• NARA: Similarly request a CONE with detailed information about your search efforts.
• Processing: 4–8 weeks
• Cost: Usually free

Important caveat:

A CONE is not a guarantee that your ancestor did not naturalize. It only certifies that a record was not found. If your ancestor naturalized outside the US (in a different country), or if records were lost or destroyed, no USCIS or NARA record would exist even if naturalization occurred elsewhere.

Using genealogy websites to locate records

Websites like Ancestry.com, FamilySearch.org, and JewishGen have digitized thousands of naturalization records. These are excellent for locating your ancestor and confirming basic information.

However, important note:

Consulates and courts will not accept screenshots or copies from genealogy websites as official proof. You must obtain official, certified copies from USCIS or NARA. That said, these websites are incredibly helpful for:

• Locating your ancestor and confirming the approximate naturalization date
• Finding alternate spellings or names used by your ancestor
• Identifying the state or jurisdiction where naturalization likely occurred
• Cross-referencing with other family documents

Once you've located your ancestor on a genealogy site, use the information to submit an official FOIA request to USCIS or NARA for a certified copy.

Common challenges in locating naturalization records

Records lost or destroyed:

Some naturalization records were lost in fires, floods, or during wars. If a consulate cannot locate a record through normal channels, USCIS can issue a CONE, though consulates may be skeptical of missing records for older cases.

Name changes or misspellings:

Your ancestor may have anglicized their name or changed it at naturalization. Search for alternate spellings and variations. Genealogy websites often flag these variants.

Records scattered across jurisdictions:

Naturalization could have occurred in any state where your ancestor lived or at a federal court. If you don't know where naturalization occurred, consult genealogy websites or state records offices to narrow the location.

Late or delayed naturalization:

Some ancestors naturalized very late in life, decades after immigration. They may not have naturalized until WWII or later. Search broadly by date and location.
