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 grandfather is a second-degree ascendant, so lett. c) can apply to him — but only on the citizenship he held, not on where he 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 grandfather held Italian citizenship when your father was born — for example because he was born in Italy and had not yet lost it — your father likely inherited Italian citizenship at birth. If your father then held Italian citizenship when you were born, you likely inherited it too. This is a two-link chain — grandfather to father to you — and the citizenship travels through each birth unless the person transmitting it had already lost it. Losing it is narrower than it sounds. For a foreign naturalization dated on or before August 15, 1992, Article 8 of Law 555/1912 required two things together: the foreign citizenship had to be acquired voluntarily, and the person had to have established residence abroad. From August 16, 1992, Article 11 of Law 91/1992 reverses the rule — an Italian citizen who acquires a foreign citizenship keeps the Italian one — so a naturalization from that date onward breaks nothing on its own. The same article carries a second limb: a citizen who resides or takes up residence abroad may renounce, and that deliberate renunciation is what ends it.

There is no 1948 issue on this path. The 1948 judicial route applies when a female ancestor's child was born before January 1, 1948. Because the qualifying ancestor here is your paternal grandfather (male), and the next link is your father (also male), no female transmission is involved — the standard consular route applies.

If your grandfather naturalized while your father was still a minor

Consulates long treated a parent's foreign naturalization as stripping their minor children of Italian citizenship at the same time — the so-called minor issue. On July 26, 2026 the Sezioni Unite of the Corte di Cassazione rejected that reading for the dual-citizen-from-birth case (sentenza n. 24045/2026): an unemancipated child born abroad who was a dual citizen from birth — Italian by descent, and a citizen of the country of birth by ius soli — kept Italian citizenship under Article 7 of Law 555/1912 despite the parent's naturalization, unless they renounced it after reaching adulthood. Interior Ministry Circular 65050 of August 10, 2026 brought comune and consular practice into line with it — the circular went to the prefectures, to be passed on to the comuni's mayors and civil-status officers, and was copied to the Foreign Ministry, which oversees the consulates — for naturalizations of the co-resident parent dated between July 1, 1912 and August 15, 1992. If your father was refused on this ground before, the circular directs applicants to ask the office that issued the refusal for a re-examination of the original application rather than filing a new one.

Legal basis

Primary law: Law 91 of 5 February 1992, Article 1, paragraph 1(a), Article 1(a): citizens by birth include “children of a father or mother who is a citizen.” Applies to each link in the chain.
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
Route: Standard consular route — no judicial proceeding required.
Chain: Italian grandfather → father (born as Italian citizen) → you (born as Italian citizen). Two naturalization checkpoints: did your grandfather naturalize before your father was born? Did your father naturalize before you were born? Neither answer settles it on its own — the loss rules above, and the minor-child exception, decide whether a naturalization actually broke the link.
Processing time: The consulate's own processing time after your appointment is not published — no consulate or ministry publishes a figure or a dataset for it. What is published is the statutory term for the decision: 36 months under Legge 19 gennaio 2026 n. 11, art. 1 (art. 10 co. 7, D.Lgs. 71/2011). That is an outer bound on the office, not a prediction for your file, and it is separate from the wait to get an appointment.

Documents typically required

1
Your paternal grandfather's Italian birth certificate. Request a certified copy (estratto integrale) from the comune where your grandfather was born. This anchors the citizenship claim.
2
Your grandfather's marriage certificate. The certificate linking your grandfather to your grandmother, apostilled and translated if issued in the US.
3
Naturalization records for your grandfather. Evidence of whether and when your grandfather 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 — those sit with state archives or the court itself. USCIS holds the duplicate certificate, in a Certificate File (C-File) for September 27, 1906 to March 31, 1956 and in the Alien File (A-File) from April 1, 1956, through its Genealogy Program.
4
Your father's birth certificate. Establishes the grandfather-to-father link. Apostilled and translated if US-issued.
5
Naturalization records for your father. Evidence of whether and when your father acquired US citizenship, to confirm the second link. If he never naturalized, the document to ask for is a Certification of Non-Existence of a Record of Naturalization, which only USCIS can issue — 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. The consulate reviews both the apostille and the translation at your appointment.
