Cessation interplay con Acuerdo IT-AR 1971

An Argentine citizen who acquires Italian nationality retains Argentine citizenship under the Argentina–Italy Dual Nationality Agreement of 1971 (Acuerdo de Doble Nacionalidad IT-AR 1971) and its 2007 Protocol — there is NO automatic loss. Acquisition family: cessation (CES); type: cessation avoided via bilateral agreement. Authorities (source register):.

Statutory framework: National Constitution of Argentina (Constitución Nacional, CN — 1853, reformed 1994) Art 75 inc 12 (Congress's power to legislate on citizenship); Ley 346 (29-10-1869) — the fundamental Argentine Citizenship Law; Ley 23.059 (22-03-1984) — restoration and reconstruction of citizenship lost under the military regime; Ley 26.957 (2014) — accession to the 1954 and 1961 Statelessness Conventions; Ley 24.071 (1992) — ILO Convention 169 on Indigenous Peoples; and the RIGI regime, Ley 27.742/2024 plus DNU 366/2025 (Incentive Regime for Large Investments — an investment regime, not a direct citizenship-by-investment pathway).

Constitutional layer: Constitución Nacional of 01-05-1853, reformed 22-08-1994. Art 75 inc 12 — legislative power over citizenship; Art 75 inc 22 — constitutional hierarchy of human-rights treaties (the federal treaty block); Art 20 — rights of foreigners equivalent to those of nationals (the foundation of the Cohelo and Hooft doctrines); Arts 89 and 91 — eligibility requirements for President and Senators.

Administrative authority: National Electoral Chamber (Cámara Nacional Electoral — exclusive appellate jurisdiction in citizenship matters); National Registry of Persons (ReNaPer); National Directorate of Migration (DNM); Ministry of the Interior; Ministry of Foreign Affairs, International Trade and Worship (MRECIC — for consular registrations); and the Federal Courts with electoral competence in each district.

This route belongs to the cessation (CES) acquisition family within the Argentine citizenship architecture. Ley 346 of 1869 — the fundamental Citizenship Law — establishes Argentine citizenship by birth on Argentine territory (broad ius soli with absolutely no diplomatic-status exclusions, a distinctive feature of Argentina), by option for children of Argentines born abroad, and by naturalization after 2 years of continuous residence with good conduct. Art 1 extends ius soli to births on Argentine vessels, in Argentine embassies, and on Argentine territory.

Leading case: CSJN Hooft, Fallos 327:5118 — the pillar doctrine: it established the principle of structural equality between Argentine citizens by birth and by naturalization for electoral purposes — naturalized citizens may not be arbitrarily excluded from elective public office. Broader impact: it invalidates discriminatory provincial exclusions.

Federal treaty block: Art 75 inc 22 CN gives federal constitutional hierarchy to human-rights treaties, including the American Declaration of the Rights and Duties of Man, the Universal Declaration of Human Rights, the Pact of San José de Costa Rica (American Convention on Human Rights, CADH), the International Covenant on Civil and Political Rights, the CRC, CEDAW, CERD, and CAT. This block applies to the interpretation of Ley 346 and Ley 23.059.

MERCOSUR: the MERCOSUR Residence Agreement (Brasilia, 06-12-2002) operates as a 2-year fast-track residence accelerator for nationals of MERCOSUR and associated states (Brazil, Uruguay, Paraguay, Bolivia, Chile, Ecuador, Colombia, Peru, Guyana, Suriname, Venezuela), combined with Ley 25.871 (Migration Law) and its implementing Decreto 616/2010.

Italian interaction: Italy's Legge 74/2025 (2025 Italian law on citizenship by descent) opens a temporal window from 01-07-2025 to 31-12-2027 for Italian-descent applications by residents of Argentina that are not tied to strict continuous residence — with a direct impact on approximately 1.5 million eligible Italian descendants in Argentina.

Spanish interaction: Spain's Ley 20/2022 (Democratic Memory Law) opens a window until 31-10-2026 for grandchildren and great-grandchildren of Republican exiles and for spouses of Spanish women who lost their nationality through marriage before 1978 — a significant impact on an estimated 80,000 eligible persons, according to the Embassy of Spain in Buenos Aires.

Operational context: This route operates under the constitutional framework of Art 75 inc 12 CN (which reserves the general naturalization law to Congress), Ley 346/1869, and the Art 75 inc 22 CN federal human-rights treaty block. CSJN Hooft, Fallos 327:5118 (2004), is the pro-dual-nationality pillar. Under settled Argentine doctrine, Argentine citizenship — whether by birth or by naturalization — is irrenounceable except under the strictly enumerated terms of Art 8 of Ley 346, which are interpreted restrictively. The bilateral agreements were confirmed as a mechanism that excludes automatic loss.

Key source anchors: Ley 346 (Citizenship Law) Arts 8–9; CSJN Hooft, Fallos 327:5118; Decreto 3213/1984 (regulatory decree on naturalization procedure).

Cumulative criteria (cessation avoided via bilateral agreement):

• (a) the 1971 Italy–Argentina Agreement plus its 2007 Protocol (approved by Ley 26.228) preserves Argentine citizenship upon acquisition of Italian nationality;
• (b) reciprocal suspension of certain rights applies until the person establishes effective domicile;
• (c) NO automatic loss, per Art 3 of the Agreement;
• (d) the Supreme Court's Hooft decision (CSJN, Fallos 327:5118) stands as the cornerstone precedent in favor of dual nationality;
• (e) the procedure runs through the Foreign Ministry (Cancillería), the Italian Consulate in Buenos Aires, and the National Registry of Persons (RENAPER).

General eligibility framework (context): Argentine citizenship law rests on broad ius soli — under Ley 346 (Citizenship Law) Art 1, everyone born on Argentine territory is Argentine by birth, with no exclusion based on the diplomatic status of the parent, a distinctive feature of Argentine law. Ius sanguinis operates through a consular option for children of Argentines born abroad (Art 1.II). Naturalization under Art 2 requires 2 years of continuous residence, good conduct, and lawful means of subsistence. The cessation framework interacts with the following acquisition tracks:

• Birth: Ley 346 Art 1 — broad ius soli with absolutely no diplomatic-status exclusions.
• Descent: Art 1.II — consular option for children of Argentines born abroad.
• Naturalization: Art 2 — 2 years of continuous residence + good conduct + lawful means of subsistence, before the competent Federal Court (Juzgado Federal).
• Marriage: no residence reduction for spouses under Ley 346 (no special spouse-reduced track).
• Restoration: Ley 23.059 (22-03-1984) — restoration and reconstruction of citizenship lost during the last military government (24-03-1976 to 10-12-1983); applicable to persons politically denaturalized, forced exiles, and earlier arbitrary denials. It operates together with Ley 23.043 and Ley 23.118 on restitution of statuses affected during the pre-democratic military period.
• Special tracks: MERCOSUR fast track under the MERCOSUR Residence Agreement (Acuerdo MERCOSUR de Residencia, Brasilia, 06-12-2002) — a 2-year residence accelerator for nationals of MERCOSUR and associated states (Brazil, Uruguay, Paraguay, Bolivia, Chile, Ecuador, Colombia, Peru, Guyana, Suriname, Venezuela), combined with Ley 25.871 (Migration Law) and its implementing Decreto 616/2010. Indigenous peoples: Ley 24.071 (1992) — accession to ILO Convention 169 on Indigenous and Tribal Peoples; Argentina was the 7th country to ratify (after Norway 1990, Mexico 1990, Colombia 1991, Bolivia 1991, Costa Rica 1993, Paraguay 1993). This provides the framework for route AR-SPC-02 (indigenous peoples) — recognition, cultural autonomy, and administrative bilingualism.
• Historical/territorial: route AR-EXT-01 — the First Transitional Provision (Disposición Transitoria Primera) of the 1994 Constitution declares: "La Nación Argentina ratifica su legítima e imprescriptible soberanía sobre las Islas Malvinas, Georgias del Sur y Sandwich del Sur y los espacios marítimos e insulares correspondientes" (the Argentine Nation ratifies its legitimate and imprescriptible sovereignty over the Malvinas Islands, South Georgia and the South Sandwich Islands and the corresponding maritime and insular spaces). This is a constitutional framework for Argentines by birth in the claimed territories, but it is NOT administratively operative while de facto British administration continues.

Bilateral dual-nationality cluster: Argentina maintains dual-nationality agreements (Convenios de Doble Nacionalidad), built on reciprocity and non-renunciation, with a 12-country Ibero-American group: Spain, Chile, Peru, Paraguay, Bolivia, Ecuador, Colombia, Honduras, Nicaragua, Costa Rica, the Dominican Republic, and Guatemala. These agreements permit dual citizenship without renunciation and reinforce equality of status.

Statelessness: Ley 26.957 (2014) — accession to the 1954 Convention relating to the Status of Stateless Persons and the 1961 Convention on the Reduction of Statelessness; Argentina deposited its instruments on 17-09-2014 and 01-06-2015 respectively. This provides the framework for route AR-BTH-04 (statelessness prevention and the residual ius soli safeguard for children).

Related loss/renunciation procedures (for contrast):

• Voluntary loss outside an agreement (Art 8, Ley 346 (Citizenship Law)): a declaratory administrative procedure before the National Directorate of Migration (DNM) with express notice to the person concerned; interpreted pro homine following CSJN Hooft, Fallos 327:5118 (2004).
• Loss for treason (Art 119 CN + Penal Code (CP) Arts 214–218): an extraordinary judicial procedure requiring a final judgment with full due-process guarantees.
• Formal renunciation: an express voluntary declaration, processed through RENAPER (National Registry of Persons) with a notarized public deed; it is reversible via route AR-RST-03 (reacquisition under Art 9 of Ley 346).

Institutional sequence (general citizenship procedure): National Electoral Chamber (Cámara Nacional Electoral — exclusive appellate jurisdiction in citizenship matters); National Registry of Persons (ReNaPer); National Directorate of Migration (DNM); Ministry of the Interior; Ministry of Foreign Affairs, International Trade and Worship (MRECIC — for consular registrations); and the Federal Courts with electoral competence in each district.

Filing channels: (1) the Federal Court with electoral competence for the applicant's domicile (for residents in Argentina); (2) an Argentine Embassy or Consulate abroad (for descent and consular-option tracks); (3) the National Directorate of Migration (DNM) for prior migratory processing.

Document compilation (per Ley 346 Art 11 and its regulations): birth certificate (apostilled and translated by a certified public translator); valid passport; certificate of domicile (ReNaPer); good-conduct certificate (Federal Police, plus the country of origin and every country of residence of 6 months or more); proof of means of subsistence (last 12 months); and tax compliance with AFIP (the federal tax authority).

Decision flow: the Federal Court transmits the case to the National Electoral Chamber (CNE) for automatic review, followed by a final judgment and the oath of allegiance; the new status is then registered with ReNaPer and the Argentine national identity document (DNI) is issued.

Investment-regime note (RIGI): the Incentive Regime for Large Investments (Régimen de Incentivos para Grandes Inversiones), under Ley 27.742/2024 (enacted 08-07-2024) and its implementing DNU 366/2025, establishes a 30-year fiscal and foreign-exchange stability regime for investments of USD 200M or more in strategic sectors. It does NOT include a direct citizenship-by-investment pathway (unlike Portugal's Golden Visa), but it accelerates permanent residence leading to naturalization under Ley 346 via the 2-year track for investors.

• Gate Registry: v1.7.8

Executive (operational) authorities:

• National Directorate of Migration (Dirección Nacional de Migraciones, DNM), Ministry of the Interior — holds naturalization competence following DNU 366/2025 (emergency decree). This transfer of competence is an unresolved legal question of high significance: it is contested as potentially ultra vires against Art 75 inc 12 of the National Constitution (Constitución Nacional, CN), which reserves legislation on citizenship to Congress.
• National Registry of Persons (Registro Nacional de las Personas, RENAPER) — issues the Argentine national identity document (DNI) and handles late registration under the consular option for children of Argentines born abroad.
• Ministry of Foreign Affairs and Worship (Ministerio de Relaciones Exteriores y Culto, the "Cancillería") — approximately 75 operating consulates for descent registration abroad and for administering the bilateral dual-nationality agreements with Italy and Spain.

Judicial authorities:

• Supreme Court of Justice of the Nation (Corte Suprema de Justicia de la Nación, CSJN) — its Hooft decision, Fallos 327:5118 (2004), is the cornerstone precedent in favor of dual nationality; constitutional protection actions (amparos) challenging DNU 366/2025 are pending in 2025–2026.
• Federal Naturalization Court (Tribunal Federal de Naturalización) — held judicial competence over naturalization prior to DNU 366/2025.
• National Chambers (Cámaras Nacionales) — oversight of emergency decrees (DNUs) under Ley 26.122 (the law governing review of decrees of necessity and urgency).

Specialist bodies for related cessation-adjacent tracks:

• For the indigenous-peoples special route: the National Institute of Indigenous Affairs (Instituto Nacional de Asuntos Indígenas, INAI), the National Registry of Indigenous Communities (Registro Nacional de Comunidades Indígenas, RENACI), and the Territorial Survey program (Relevamiento Territorial, RETECI).
• For the investment-linked special route: the Citizenship-by-Investment Programs Agency (Agencia de Programas de Ciudadanía por Inversión), established under Decreto 524/2025.
• For the Malvinas-related external route: the Argentine Consulate in London and the Cancillería's Directorate of Malvinas and South Atlantic Affairs (Dirección Malvinas y Atlántico Sur).
