Italian citizenship by naturalization is a residency‑based pathway that allows foreign nationals to become Italian citizens after meeting specific legal, financial, and integration requirements. Unlike citizenship by descent—which is a recognition of a pre‑existing right—naturalization is a discretionary act of the Italian State. This means that even when all requirements are met, approval is not automatic. Authorities evaluate the applicant’s conduct, integration, and compliance with Italian law before granting citizenship. Naturalization is therefore a structured, evidence‑driven process that requires careful documentation and uninterrupted legal residence in Italy.
Residency as the foundation of eligibility
Residency is the central pillar of Italian citizenship naturalization. Applicants must demonstrate continuous, legal residence in Italy for a minimum number of years, depending on their category:
- Non‑EU citizens: 10 years of legal residence
- EU citizens: 4 years of legal residence
- Stateless individuals or refugees: 5 years
- Descendants of Italian citizens (children or grandchildren of Italian citizens by birth): 2 years
- Spouses of Italian citizens: 2 years of residence in Italy (or 3 years abroad), subject to additional conditions
These timelines begin only after the applicant is officially registered at the anagrafe (municipal registry). Temporary stays, tourist periods, or time spent waiting for a permesso di soggiorno do not count toward the residency requirement. The law emphasizes continuity, meaning that long absences from Italy can interrupt the residency period and reset the clock.
Impact of Decree‑Law 36/2025 (Law 74/2025) on residency requirements
A major legislative update came with Decree‑Law 36/2025, later converted into Law 74/2025, which significantly modified requirements for citizenship by residency for individuals with Italian ancestry up to the second degree. Under the new provisions, anyone with a parent or grandparent who was an Italian citizen by birth can now apply for citizenship after two years of legal residence in Italy, reduced from the previous three‑year requirement. All other conditions remain unchanged: applicants must be legally registered residents for the entire qualifying period, hold a valid residence permit, demonstrate B1‑level Italian language proficiency, and submit criminal background certificates and proof of income.
The law also introduced an important benefit for those seeking to move to Italy for work. Descendants of Italian citizens living abroad may now obtain a work visa outside the standard quota system, making it easier to enter and reside in Italy for employment purposes. This provision, combined with the reduced residency requirement, significantly streamlines the path to naturalization for eligible descendants.
Financial eligibility requirements
Applicants must demonstrate financial stability for the three years preceding the application. The minimum income thresholds are based on the ISEE (Indicatore della Situazione Economica Equivalente) and vary depending on household composition:
- A single applicant must show a minimum annual income of €8,263.31
- A married couple must demonstrate a minimum yearly income of €11,362.05
- An additional amount of €516.46 apply for each dependent family member
Income can come from employment, self‑employment, pensions, or other legally recognized sources.
Language proficiency requirement (B1 or higher)
Since 2018, applicants must demonstrate B1‑level proficiency in Italian, according to the Common European Framework of Reference for Languages (CEFR). Accepted certificates must come from recognized institutions such as:
- Università per Stranieri di Perugia
- Università per Stranieri di Siena
- Società Dante Alighieri
- Università Roma Tre
This requirement ensures that applicants can participate fully in Italian civic life.
Step‑by‑step overview of the naturalization procedure
The naturalization process begins with registration at the anagrafe, where the applicant establishes legal residence. Once residency is confirmed, the applicant gathers all required documents, including birth certificates, criminal background checks, income documentation, and proof of continuous residence.
The application is submitted digitally through the Ministero dell’Interno portal. Applicants must create an account, upload all documents, and pay the €250 administrative fee. After submission, the Ministry conducts background checks, verifies residency continuity, and evaluates the applicant’s integration and conduct. Processing times vary, but most cases take 24 to 36 months.

Required documentation for naturalization
Applicants must prepare a complete set of documents, including:
- Birth certificate (translated and authenticated with an apostille)
- Criminal background certificates from all countries of residence. US citizens must provide criminal background certificates for every state they have lived in.
- Proof of continuous residence in Italy
- Tax returns for the previous three years
- Valid passport and Italian residence permit (if applicable)
- B1 language certificate
- Marriage certificate (if applying through marriage)
Applicants with Italian ancestry who apply for citizenship by residency must also submit the vital records of their Italian ancestors as part of the documentation. Additionally, marital documentation requirements differ by gender: married men do not need to provide a certified marriage certificate, while married women who changed their surname must present either their marriage certificate or another official document that explains the name change.
All foreign documents must be translated into Italian and authenticated with an apostille. Missing or inconsistent documentation can delay or jeopardize the application.
Monitoring continuity of residence
Italian authorities closely monitor the continuity of residence. Extended absences—typically more than six consecutive months or more than ten months total within the required period—may interrupt residency and restart the eligibility timeline. Applicants must maintain their registration at the anagrafe and avoid prolonged stays abroad. Municipalities and the Ministry cross‑check residency records, tax filings, and immigration data to confirm uninterrupted presence.
Criminal background checks and good conduct requirements
Naturalization requires a clean criminal record in Italy and in all previous countries of residence. Authorities evaluate not only criminal convictions but also overall civic conduct, including compliance with immigration laws, tax obligations, and public order. Even minor legal issues can delay or negatively affect the application.
Naturalization vs. Recognition by descent (jus sanguinis)
Unlike jus sanguinis, which is a right based on ancestry, naturalization is discretionary. This means that documentation must be precise, residency must be continuous, and the applicant must demonstrate full integration. The State retains the authority to deny applications even when all formal requirements are met.
Frequently Asked Questions
How long does the naturalization process take after submitting the documents?
Most applications take 24–48 months, depending on administrative workload and document verification.
Can I include my minor children in my residency‑based naturalization application?
Yes. Minor children can be included, provided they reside legally with the applicant in Italy.
What happens if I change my address within Italy during the process?
You must update your residency at the new municipality. The Ministry will automatically receive the updated information, but delays may occur if the transfer is not properly registered.
