Doble Nacionalidad IT-AR (Acuerdo 1971 + Protocolo 2007)

This route covers dual nationality between Italy and Argentina under the Italy–Argentina Dual Nationality Agreement of 1971 and its Additional Protocol of 2007.

Eligibility in brief: Italian citizens may acquire Argentine nationality without losing their Italian nationality, under the 1971 Dual Nationality Agreement (ratified in Argentina by Ley 20.588) and the 2007 Additional Protocol (ratified by Ley 26.228). Under the Agreement's mechanics, the rights attached to one of the two nationalities remain suspended until the person takes up domicile in the country of origin — only one nationality is fully operative at a time.

Operational context: The route operates within Argentina's constitutional framework: Art 75 inc 12 of the National Constitution (which reserves the general naturalization law to Congress), Ley 346/1869 (Citizenship Law), and Art 75 inc 22 of the Constitution (the federal block of human-rights treaties with constitutional hierarchy). Ley 346 of 1869 (the "Ley Avellaneda") is Argentina's fundamental citizenship statute:

• Art 1.1 — jus soli without conditions;
• Art 1.2 — jus sanguinis, subject to consular registration or option;
• Art 2 — naturalization after 2 years of residence;
• Art 2 bis — meritorious exceptions (expanded by Ley 24.951/1998);
• Art 8 — loss of citizenship through voluntary acquisition of another nationality where no agreement applies;
• Art 9 — reacquisition.

The statute is implemented by regulation Decreto 3213/1984.

Key case law: CSJN "Hooft" (Fallos 327:5118, 2004) is the pillar of Argentina's pro-dual-nationality doctrine. Under Argentine doctrine, Argentine citizenship — whether acquired by birth or by naturalization — cannot be renounced except in the strict, exhaustively listed terms of Art 8 of Ley 346, which is interpreted restrictively. The case law confirmed bilateral agreements as a mechanism that excludes automatic loss of Argentine citizenship.

The documentation for this route is anchored to primary sources: the National Constitution, Ley 346, the implementing regulation Decreto 3213/1984, the National Registry of Persons (Registro Nacional de las Personas, ReNaPer), and the consular manual of the Foreign Ministry (Manual Consular, Cancillería).
