Readquisición de ciudadanía argentina

This route covers the reacquisition of Argentine citizenship by a person who lost it voluntarily — Art 9 of Ley 346 (the foundational Citizenship Law) together with the case law of the Supreme Court (Corte Suprema de Justicia de la Nación, CSJN). It belongs to the restoration family of pathways within the Argentine citizenship architecture (acquisition type: reacquisition; primary authorities:).

Statutory framework: The National Constitution of Argentina (Constitución Nacional, CN — adopted 01-05-1853, reformed 22-08-1994), Art 75 inc 12, assigns Congress the power to legislate on citizenship. Ley 346 (29-10-1869) is the fundamental Citizenship Law. Ley 23.059 (22-03-1984) restored and reconstructed citizenship lost during the military regime. Ley 26.957 (2014) acceded to the 1954 and 1961 Statelessness Conventions. Ley 24.071 (1992) adopted ILO Convention 169 on Indigenous Peoples. Ley 27.742/2024 and DNU 366/2025 (executive emergency decree) establish the RIGI (Régimen de Incentivos para Grandes Inversiones — Incentive Regime for Large Investments).

Constitutional layer: Art 75 inc 12 CN (congressional power over citizenship legislation); Art 75 inc 22 CN (constitutional hierarchy for human-rights treaties — the federal block, 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), the International Covenant on Civil and Political Rights, the Convention on the Rights of the Child, CEDAW, CERD, and CAT — applicable to the interpretation of Ley 346 and Ley 23.059); Art 20 CN (foreigners enjoy rights equivalent to nationals — the foundation of the Cohelo and Hooft doctrines); Arts 89 and 91 CN (eligibility rules for President and Senators).

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

Core doctrine: Ley 346/1869 establishes Argentine citizenship by birth in Argentine territory (broad ius soli with 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 Argentine vessels, embassies, and territory. The CSJN's Hooft decision (Fallos 327:5118) established structural equality between citizens by birth and by naturalization for electoral purposes — naturalized citizens cannot be arbitrarily excluded from elective public office, invalidating discriminatory provincial exclusions.

Interacting regimes: The MERCOSUR Residence Agreement signed in Brasilia (06-12-2002) provides 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 and Decreto 616/2010. Italy's Legge 74/2025 opens a temporal window (01-07-2025 to 31-12-2027) for Argentine residents of Italian descent to naturalize without strict continuous-residence ties — directly affecting an estimated ~1.5M eligible Italian descendants in Argentina. 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 nationality through marriage before 1978 — an estimated ~80,000 eligible persons according to the Spanish Embassy in Buenos Aires. Argentina also maintains a 12-country Ibero-American cluster of bilateral dual-nationality conventions (reciprocity, no renunciation), and the RIGI investment regime is an investment incentive, not a citizenship-by-investment program.

Operational context for this route: Reacquisition operates under Art 75 inc 12 CN (legislative reserve to Congress for the general naturalization law), Ley 346/1869, and the Art 75 inc 22 CN federal human-rights block. Key supporting sources: (Ley 23.059/1984), (1954 Convention), (1961 Convention), (CONARE/DNM statelessness).

This restoration route covers the reacquisition of Argentine citizenship by a person who previously lost it voluntarily — governed by Art 9 of Ley 346 (the foundational Citizenship Law of 1869) together with the case law of the Supreme Court (Corte Suprema de Justicia de la Nación, CSJN). Primary authorities:.

Core cumulative criteria:

• (a) The applicant is a former Argentine who lost citizenship voluntarily (Art 8 Ley 346) or through acquiring the nationality of a country with which Argentina has no bilateral dual-nationality agreement (the position before the CSJN's Hooft decision).
• (b) The reacquisition procedure of Art 9 Ley 346 is pursued via the National Registry of Persons (RENAPER) / National Directorate of Migration (DNM).
• (c) After CSJN Hooft (Fallos 327:5118), a more restrictive doctrine applies to what constitutes loss of citizenship in the first place — narrowing the situations in which citizenship is treated as lost.
• (d) There is no prior-residence requirement for reacquisition.
• (e) This route operates as the reverse of the bilateral dual-nationality convention routes (AR-CES-03/05).

General eligibility framework in which this route sits: Argentina applies broad ius soli (Ley 346 Art 1) — all persons born in Argentine territory are Argentines by birth, with no exclusion based on a parent's diplomatic status, a distinctive feature of the Argentine system. Children of Argentines born abroad may opt for citizenship through the consular option (Art 1.II). Naturalization under Art 2 requires 2 years of continuous residence, good conduct, and lawful means of subsistence, before the competent Federal Court (Juzgado Federal). Marriage confers no reduced-residence track under Ley 346.

Restoration context: Ley 23.059 (22-03-1984) restored and reconstructed citizenship lost during the last military government (24-03-1976 to 10-12-1983), applying to persons politically denaturalized, forced into exile, or subjected to prior arbitrary denials; it operated together with Ley 23.043 and Ley 23.118 on restitution of pre-democratic-era statuses.

Related accelerators and frameworks: The MERCOSUR Residence Agreement signed in Brasilia (06-12-2002) provides 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. Ley 24.071 (1992) adopted 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), framing the indigenous-peoples pathway (AR-SPC-02) with cultural autonomy and administrative bilingualism. The First Transitory Provision of the 1994 Constitution affirms Argentina's "legitimate and imprescriptible sovereignty" over the Malvinas, South Georgia, and South Sandwich Islands and the corresponding maritime and insular spaces — the constitutional frame for the AR-EXT-01 pathway, which is not administratively operative while de facto British administration continues.

Bilateral cluster: Argentina maintains dual-nationality conventions (reciprocity, no renunciation required) with a 12-country Ibero-American group: Spain, Chile, Peru, Paraguay, Bolivia, Ecuador, Colombia, Honduras, Nicaragua, Costa Rica, the Dominican Republic, and Guatemala — allowing dual citizenship without renunciation and an amplified equality of status.

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

• Phase 1 — Verification of loss: the former Argentine establishes a prior voluntary loss of citizenship (Art 8 of Ley 346, the Citizenship Law, as applied before the CSJN's Hooft decision) or loss through acquiring the nationality of a country with which Argentina has no bilateral dual-nationality agreement.
• Phase 2 — Application under Art 9 Ley 346: the reacquisition procedure is filed before the National Registry of Persons (RENAPER) / National Directorate of Migration (DNM).
• Phase 3 — Effect of CSJN Hooft (Fallos 327:5118): the Supreme Court's more restrictive doctrine on what constitutes loss of citizenship facilitates reacquisition.
• Phase 4 — Documentation: proof of former Argentine citizenship, proof of the loss, and current identity documents.
• Phase 5 — Decision: issuance of the reacquisition record (acta) and a restored Argentine DNI (national identity document).

Institutional chain: the National Electoral Chamber (Cámara Nacional Electoral — exclusive appellate jurisdiction in citizenship matters); the National Registry of Persons (ReNaPer); the National Directorate of Migration (DNM); the Ministry of the Interior; the 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 (domestic residents); (2) an Argentine Embassy or Consulate abroad (descent and consular-option tracks); (3) the National Directorate of Migration (DNM) for prior migration processing.

Document compilation under 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 file to the National Electoral Chamber (CNE) for automatic review, followed by a final judgment and the oath of loyalty; the applicant is then registered with ReNaPer and the Argentine DNI is issued.

Investment-regime note: the RIGI (Régimen de Incentivos para Grandes Inversiones — Incentive Regime for Large Investments), established by Ley 27.742/2024 (promulgated 08-07-2024) with DNU 366/2025 as implementing decree, grants 30-year fiscal and exchange-rate stability 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 toward naturalization under Ley 346 via the 2-year track for investors.

Operational executive authorities:

• National Directorate of Migration (Dirección Nacional de Migraciones, DNM), Ministry of the Interior — holds naturalization competence following DNU 366/2025 (executive emergency decree). This transfer of competence is legally contested as potentially exceeding executive power, since Art 75 inc 12 of the National Constitution (Constitución Nacional, CN) reserves citizenship legislation to Congress; the question remains unresolved.
• National Registry of Persons (Registro Nacional de las Personas, RENAPER) — issues the Argentine DNI (national identity document) and handles late registration under the consular option for descent cases.
• Ministry of Foreign Affairs and Worship (Ministerio de Relaciones Exteriores y Culto, "Cancillería") — approximately 75 operating consulates for descent registration and for administration of 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) — the Hooft decision, Fallos 327:5118 (2004), is the cornerstone precedent favoring dual nationality; constitutional protection actions (amparos) challenging DNU 366/2025 are pending in 2025–2026.
• Federal Naturalization courts (Tribunal Federal de Naturalización) — held judicial competence over naturalization before DNU 366/2025.
• National Chambers of Appeal (Cámaras Nacionales) — exercise review of executive emergency decrees under Ley 26.122 (law on congressional control of decrees of necessity and urgency).

Specialist bodies for related restoration and special pathways:

• Indigenous-peoples cases: 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).
• Investment cases: the Citizenship-by-Investment Programs Agency (Agencia de Programas de Ciudadanía por Inversión), created by Decreto 524/2025.
• Malvinas/Falklands matters: the Argentine Consulate in London together with the Foreign Ministry's Directorate of Malvinas and South Atlantic Affairs (Dirección Malvinas y Atlántico Sur).
