Law 74/2025 may affect this path
Under Article 3-bis of Law 91/1992, anyone born outside Italy who holds another citizenship is treated as never having acquired Italian citizenship, unless one of five saving conditions applies. The ancestor-based condition is a parent or grandparent who holds, or held when they died, exclusively Italian citizenship — not merely one who was born in Italy. Your paternal grandmother is a second-degree ascendant, so lett. c) can apply to her — but only on the citizenship she held, not on where she was born. Three of the five close on the same moment, 23:59 Rome time on March 27, 2025: a consular or comune application filed by then (lett. a), an appointment the competent office had already communicated to you by then with the application filed on the appointed day (lett. a-bis), and a judicial claim filed by then (lett. b). The other two are about your ascendants and carry no deadline: a parent or grandparent who holds, or held at death, exclusively Italian citizenship (lett. c), or a parent or adoptive parent — the statute says «un genitore o adottante» — who lived in Italy for two continuous years after acquiring Italian citizenship and before you were born or adopted (lett. d). This is the question that decides this page — check it against your own family's naturalisation records before assuming either answer.
If your paternal grandmother was born in Italy and held Italian citizenship, she may have transmitted it to your father — and your father to you. The key variable is your father's date of birth. The Italian Constitution came into force on January 1, 1948 and made men and women equal before the law; the Constitutional Court later used that guarantee to strike down the rule that only a father could pass citizenship to a child (Sentenza 30/1983). A declaration of unconstitutionality can only reach back to the day the Constitution took effect, which is why January 1, 1948 — and not 1983 — is the dividing line. If your father was born on or after that date, the standard consular route applies. If he was born before it, the 1948 judicial route is required.
Was your father born before January 1, 1948?
If your father was born on or after January 1, 1948: The standard consular route applies. Your grandmother's Italian citizenship transmitted to your father under post-constitutional equality rules, and from your father to you. No judicial proceeding is required.
If your father was born before January 1, 1948: The 1948 judicial route is required. Under Italy's pre-constitutional citizenship laws, women could not transmit citizenship to their children. Your grandmother could not have legally passed citizenship to your father under the rules that existed at his birth. A court proceeding challenges that discrimination. See the 1948 case guide →
Legal basis
- Primary law
- Law 91 of 5 February 1992, Article 1, paragraph 1(a), Article 1(a) — applies when your father was born on or after January 1, 1948.
- 1948 route basis
- Corte Costituzionale, Sentenza 30/1983 — which struck down Article 1 no. 1 of Law 555/1912 for not making the child of an Italian mother a citizen by birth — together with Sentenza 87/1975 on the loss of citizenship by marriage to a foreigner, applied by Cassazione Sezioni Unite n. 4466/2009. Applies when your father was born before January 1, 1948.
- Authority
- Italian Ministry of Foreign Affairs (MAECI) — decided today by the competent Italian consulate, and from January 1, 2029 by a central MAECI office in Rome
- Processing time
- Consular route: the consulate's own processing time after your appointment is not published; the statutory term for the decision is 36 months under Legge 19 gennaio 2026 n. 11, art. 1 (art. 10 co. 7, D.Lgs. 71/2011). Judicial route: not published either — no tribunale or ministry publishes a duration for 1948 cases. The judicial route is not closed: filing a claim by 23:59 Rome time on March 27, 2025 puts you outside Article 3-bis entirely (letter b), but a claim filed after that moment is still heard — it is simply decided under Article 3-bis like any other application.

Check your eligibility →Documents typically required
- 1
Your paternal grandmother's Italian birth certificate. Request a certified copy (estratto integrale) from the Italian comune where your grandmother was born. This anchors the citizenship claim.
- 2
Your grandmother's marriage certificate. Links your grandmother to your grandfather in the chain. Apostilled and translated if US-issued.
- 3
Naturalization records for your grandmother. Evidence of whether and when your grandmother acquired US citizenship. The National Archives holds naturalizations granted by federal courts before October 1991 and says that, as a general rule, it does not hold naturalizations created in state or local courts. USCIS holds the duplicate certificate — a Certificate File (C-File) for September 27, 1906 to March 31, 1956, an Alien File (A-File) from April 1, 1956 — through its Genealogy Program.
- 4
Your father's birth certificate. Establishes the grandmother-to-father link and confirms your father's date of birth — which determines whether the consular or judicial route applies.
- 5
Naturalization records for your father. Evidence of whether and when your father acquired US citizenship. If he never naturalized, ask USCIS for a Certification of Non-Existence of a Record of Naturalization — the National Archives can issue only a negative search letter.
- 6
Your birth certificate. Long-form certificate showing both parents' names. Apostilled and accompanied by a certified Italian translation.
- 7
Certified Italian translations. All US-issued documents require a certified Italian translation by a qualified sworn translator.
