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 maternal 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 maternal grandmother was born in Italy and held Italian citizenship, she may have transmitted it to your mother — and your mother to you. As with the paternal grandmother path, the critical date is your mother's birth date. 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 mother was born on or after that date, the standard consular route applies. If she was born before it, the 1948 judicial route is required.

This path involves two female-to-child transmissions in the chain: grandmother to mother, and mother to you. The 1948 rule is triggered by the grandmother-to-mother link — specifically, whether your mother was born before January 1, 1948. Your own birth date does not affect the analysis unless you were also born before January 1, 1948, in which case the mother-to-you link falls on the same side of the line.

Was your mother born before January 1, 1948?

If your mother was born on or after January 1, 1948: The standard consular route applies. Your grandmother's Italian citizenship transmitted to your mother under post-constitutional equality rules, and from your mother to you. No judicial proceeding is required.

If your mother 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 mother under the rules that applied at her birth. See: Through Your Mother (Born Before 1948) →

Legal basis

Primary law: Law 91 of 5 February 1992, Article 1, paragraph 1(a), Article 1(a) — applies when your mother 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 mother 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.

Documents typically required

1
Your maternal 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 mother's birth certificate. Establishes the grandmother-to-mother link and confirms your mother's date of birth — which determines whether the consular or judicial route applies.
5
Naturalization records for your mother. Evidence of whether and when your mother acquired US citizenship. If she 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.
