The History of Argentina’s Citizenship Laws and Decree 524/2025 Explained

Introduction: Why Decree 524/2025 Is Historic

In July 2025, Argentina introduced Decree 524/2025, the procedural and institutional framework for citizenship by investment. It builds on DNU 366/2025, issued in May 2025, which amended the Nationality Law so that a qualifying investment can replace the two-year residency requirement. Implementing regulations remain pending.

This reform represents a pivotal moment. For the first time, foreign investors would be able to obtain Argentine citizenship directly through economic contribution rather than years of physical residency.

Decree 524/2025 is more than an administrative update. It marks Argentina’s entry into the global investment-migration market, positioning the country as a credible alternative to traditional programs in Europe and the Caribbean. Understanding its background and legal underpinnings is essential for investors preparing to participate once applications open.

Evolution of Argentina’s Nationality Law

Argentina’s citizenship framework has deep constitutional roots. Since the adoption of the 1853 Constitution, the country has followed a combination of jus soli (citizenship by birth on national soil) and jus sanguinis (citizenship by descent) principles.

The cornerstone of modern nationality law remains Law No. 346, enacted in 1869. It provides that people born in Argentina are Argentine, and that children born abroad to native-born Argentine parents may opt for Argentine nationality. It also sets the conditions for naturalization: two years of continuous residence and a petition before a federal judge.

However, prior to 2025, Argentina had no legal mechanism for direct citizenship by investment. The traditional process relied on judicial discretion, often resulting in inconsistent outcomes and lengthy timelines. Decree 524/2025 was designed to standardize this process within a clear administrative framework.

Legal Foundation for Citizenship by Investment

Decree 524/2025 does not replace Argentina's existing nationality law. It expands upon it. Its foundation lies in the constitutional principle of equal civil rights for foreigners, stated in Article 20 of the Argentine Constitution. This article grants foreign residents the same civil rights as citizens, including property ownership, industry participation, and the ability to acquire nationality under prescribed conditions.

Building on this, DNU 366/2025 introduced the underlying principle: that a qualifying investment could substitute for the two-year residency period the naturalization process otherwise requires. Decree 524/2025 then built the administrative pathway on top of that change, defining how qualified investors could obtain citizenship directly through a qualifying investment.

The decree also establishes a new institutional body: the Agency for Citizenship by Investment Programs (Agencia de Programas de Ciudadanía por Inversión), to oversee application processing, investment verification, and compliance with anti-money-laundering standards.

This framework signals Argentina's intent to align with international transparency norms, a model designed to be efficient and transparent, whose legal basis is now being tested in the courts.

What Decree 524/2025 Changes

Decree 524/2025 builds three primary legal and administrative reforms on top of the citizenship-through-investment principle introduced by DNU 366/2025:

• Citizenship through Economic Contribution
  Under the framework, investors would qualify for Argentine citizenship through a qualifying investment. On 2 October 2026 the Ministry of Economy officially announced USD 350,000 as a non-refundable contribution to the National Treasury, or USD 800,000 in a government bond, for the main applicant. These figures are not yet codified in law.

• Defined Processing Timelines
  Under Decree 524/2025, the National Directorate of Migration must decide within 30 business days of receiving the Agency's assessment report. That decision deadline is far shorter than prior judicial naturalization processes, which often took years, although the assessment stage itself has no published timeline.

• Multi-Agency Oversight and Compliance
  A coordinated compliance framework has been established between the Ministry of Economy, Migration Authority, Financial Intelligence Unit (UIF), and Ministry of Justice. This ensures due diligence procedures meet global anti-money-laundering (AML) and counterterrorism-financing (CTF) standards.

Together, these reforms transform Argentina's citizenship process from a purely judicial matter into a regulated, executive-administered framework, aiming to combine legal certainty with administrative transparency.

Implementation Timeline and Next Steps

Decree 524/2025 was published in July 2025, initiating Argentina's first structured citizenship-by-investment framework. The next phase is an implementing regulation that codifies the investment amounts announced on 2 October 2026 and sets fees, procedures and documentation standards.

The implementation timeline currently anticipates:

• May 2025: DNU 366/2025 amends the Nationality Law to allow investment in place of residency.
• July 2025: Decree 524/2025 published, establishing the legal framework.
• April 2026: Resolution 522/2026 cancels the operator tender (not the program).
• June 2026: Two federal courts declare DNU 366/2025 invalid; the government's appeal is before the Supreme Court.
• 2 October 2026: Ministry of Economy announces pricing and a government target of Q4 2026.
• Pending: Implementing regulation codifying the amounts, plus fees, procedures and application documentation standards.
• Application window: Government target Q4 2026. Not yet open.

The program's no-residency provision comes from DNU 366/2025, which two federal courts declared invalid in June 2026 and which is now before the Supreme Court on the government's appeal. Decree 524/2025 remains formally in force. Applications are not yet open. Government target: Q4 2026, though slippage remains possible.

Legal Interpretations: Supporters and Critics

Investors are encouraged to begin preparing documentation, proofs of funds, and due diligence materials now to ensure readiness when the application window opens.

Supporters of the framework describe it as a modernization that reflects Argentina's shift toward global economic integration. They argue that it:

• Preserves Argentina’s sovereign control over nationality.
• Aligns investment-based citizenship with economic development objectives.
• Embeds transparency mechanisms consistent with OECD and FATF standards.

Supporters emphasize that this reform is not a departure from Argentina's legal tradition but an evolution of it, modernizing a centuries-old system to meet the needs of an internationalized economy.

Critics, and two federal courts in June 2026, take the opposite view on the central point: citizenship touches political rights the Constitution reserves for Congress, so the residency requirement cannot be changed by emergency decree. The Supreme Court's decision on DNU 366/2025 will settle the question.

Conclusion: The Legal Foundation of a New Global Opportunity

Decree 524/2025 represents the most significant transformation in Argentina’s nationality framework since Law No. 346 was enacted over 150 years ago.

By formally establishing an investment-based pathway to citizenship, Argentina has positioned itself as a credible, G20-backed alternative in the global citizenship-by-investment market.

The combination of an administrative framework, a defined decision deadline and international transparency standards gives Argentina's Citizenship by Investment program a substantive structure, though its no-residency framework remains subject to the ongoing Supreme Court review described above.
