Argentina fast-track naturalisation. 2 continuous years of legal residence on a valid residence permit, now materially tightened by Presidential Decree 366/2025 (Milei, May 2025) — any departure from Argentine territory resets the clock. Administratively handled by the Dirección Nacional de Migraciones (DNM) post-decree rather than federal courts, with pre-May-2025 court filings grandfathered under the old regime.
The Argentine Republic (population ~46 million; capital Buenos Aires) has historically offered one of the shortest residence-based naturalisation frameworks in the world — just 2 years of legal residence under Article 2 of Law 346 of 1869. CRITICAL 2025 CHANGE: on May 2025, President Javier Milei signed Presidential Decree 366/2025, which materially tightened the 2-year rule. Under the post-decree framework, the 2 years must be continuous legal residence on a valid residence permit without leaving Argentina — any departure from Argentine territory now resets the clock to zero. Previously the rule was interpreted more flexibly to permit short absences. The decree also moved citizenship applications from federal courts to administrative processing by the Dirección Nacional de Migraciones (DNM). Applications filed with federal courts before May 2025 are grandfathered under the pre-decree regime. Milei has also announced a new Investment Citizenship Program expected to launch 2026-2027, with investments from US$500,000+ in energy, agriculture, technology, and tourism sectors potentially waiving the 2-year residency for qualifying investors. Dual citizenship is fully permitted; no formal Spanish language exam (an informal interview covers basic conversational ability); no civics test. Argentina is Mercosur, G20, and maintains the strongest Spanish-speaking South American passport for visa-free access — approximately 172 destinations including the UK (ETA), Schengen, US (ESTA from Dec 2025 reinstated), Canada (eTA), Russia, and most of Asia.
Used by applicants genuinely relocating to Buenos Aires, Mendoza, Bariloche, or Córdoba who can commit to the new 2-continuous-year no-departure rule under Decree 366/2025; pre-May-2025 court-filing applicants grandfathered under the flexible pre-decree regime; prospective Investment Citizenship Program applicants preparing US$500k+ qualifying investments for the 2026-2027 launch; and spouses of Argentine citizens (naturalisation available after just 2 years of marriage with no residency-break test) — for whom Argentine citizenship delivers Mercosur passport rights, G20 diplomatic weight, and one of the strongest Latin American passports for visa-free mobility.
Why Argentine fast-track naturalisation — post-Decree 366/2025
Argentina remains one of the shortest residence-based naturalisation routes in the world at just 2 years, but the May 2025 Milei reform fundamentally changes the practical calculus — you now genuinely have to LIVE in Argentina continuously for those two years.
2 continuous years (no departures, post-May-2025)
Presidential Decree 366/2025, signed by President Javier Milei in May 2025, requires 2 continuous years of legal residence on a valid residence permit without leaving Argentine territory. Any departure resets the clock to zero. Previously the rule permitted short absences; post-decree applicants must genuinely remain in-country throughout the qualifying period. This is the single most important rule for any post-May-2025 applicant to plan around.
Pre-May-2025 court-filing grandfathering
Applications filed with the federal courts before May 2025 are grandfathered under the pre-decree regime, which interpreted the 2-year rule more flexibly to permit short absences for travel, family events, or business. If you have a pre-May-2025 court filing still in process, Liberty Mundo's continuation service keeps it on the old framework.
New DNM administrative route (post-decree)
Decree 366/2025 moved citizenship applications from federal courts to administrative processing by the Dirección Nacional de Migraciones (DNM). In practice this means faster decisions (12-18 months versus the historic 24-36 months through the courts), more predictable documentation requirements, and clearer online status tracking.
Upcoming Investment Citizenship Program (2026-2027)
Milei has announced a new Investment Citizenship Program expected to launch in 2026-2027 with investments from US$500,000+ in qualifying sectors: energy, agriculture, technology, and tourism. The 2-year residency requirement will be waivable for qualifying investors. Liberty Mundo is tracking the implementing regulations and will offer pre-launch advisory for high-net-worth clients.
Strongest Spanish-speaking South American passport
The Argentine passport delivers approximately 172 visa-free / visa-on-arrival destinations — the strongest in Spanish-speaking South America. Coverage includes the UK (ETA), full Schengen, US (ESTA from December 2025 reinstated after the 2002 withdrawal), Canada (eTA), Japan, Singapore, Russia, and most of Asia and Africa. Full Mercosur passport rights to live and work in Brazil, Paraguay, and Uruguay.
Spouse / parent fast-track
Spouses of Argentine citizens can naturalise after just 2 years of marriage with residence in Argentina — the 2-year requirement is measured from marriage, not from arrival. Parents of Argentine-born children similarly qualify on an accelerated basis. Both routes are unaffected by Decree 366/2025's no-departure rule in practice, since the underlying residence interpretation differs.
What's included in the service
Everything required to move from Decree 366/2025 impact analysis through residency and 2 continuous years in-country to DNM naturalisation and passport, handled end-to-end by Liberty Mundo in coordination with Argentine licensed counsel (abogados matriculados).
Argentina fast-track vs other Americas naturalisation routes
Argentina's 2-year track remains competitive, but Decree 366/2025's no-departure rule materially narrows the applicant pool to those who can genuinely live in Argentina continuously. Here is how it lines up against the alternatives.
| Feature | Argentina (post-Decree 366) | Honduras | Paraguay | Dominican Republic |
|---|---|---|---|---|
| Shortest residency | 2 continuous years (no departures) | 1 year (CA nationals) | 3 years | 6 months (Law 1683 investor) |
| Departure rule | Any departure resets the clock | 180+ days/yr typical | Flexible (some absences OK) | Flexible (180+ days/yr) |
| Dual citizenship | Permitted | Permitted (since 2003) | Permitted | Permitted |
| Language requirement | Informal Spanish interview | Spanish interview | Basic Spanish | None |
| Civics test | None | Yes (Constitution + geography + history) | None | None |
| Visa-free destinations | ~172 | ~135 | ~146 | ~75 |
| Processing time | 12-18 months (DNM) or 24-36 (court) | 12-24 months | 12-24 months | 6-12 months |
| Typical Liberty Mundo fee | US$4,500 | US$6,500 | US$6,500 | US$5,500 |
Argentina remains the standout for anyone who can genuinely commit to living continuously in the country for two years — the strongest Latin American passport for visa-free mobility, no civics test, no formal language exam, no renunciation. Post-Decree 366/2025 the trade-off is strict: you really cannot leave during the qualifying period. Clients who need travel flexibility during residency are materially better served by the Dominican Republic (Law 1683 investor 6 months) or Paraguay (3 years with flexible absences).
How the Argentina fast-track process runs
Three stages: Decree 366/2025 impact analysis and residency-track selection; 2 continuous years of Argentine residence under the no-departure rule; DNM or court naturalisation filing (depending on pre / post-decree status) and passport issuance.
Eligibility and application pack
We confirm you qualify for the program, then gather your documents and assemble the complete application pack.
2 continuous years with no departures
DNM residence-permit issued and maintained on a valid Rentista / Inversionista / Pensionado basis. Physical Argentine presence maintained throughout the 2-year qualifying period without any departure from Argentine territory — post-decree, this is a hard rule. Continuous-presence log maintained and evidenced via entry-exit stamps. Informal Spanish-conversation preparation for the DNM interview. Rental housing (typically Buenos Aires Palermo / Recoleta / Belgrano, or Córdoba / Mendoza / Bariloche for lower-cost alternatives) and day-to-day integration.
Naturalisation filing, DNI, and passport issuance
For post-decree applicants: DNM administrative citizenship filing with continuous-presence evidence, residence-permit records, DNM interview, and supporting documentation. 12-18 month review. For pre-decree grandfathered applicants: court continuation through the federal court system. On approval: Documento Nacional de Identidad (DNI) issuance through RENAPER, followed by biometric Argentine passport. Full Mercosur free-movement onboarding.
Optional add-ons
Typical complex-case work Argentine fast-track clients request. Priced separately; quoted on request.
Pre-decree court-filing continuation
For applicants with pending pre-May-2025 court-filed applications: full continuation service through the federal courts under the grandfathered pre-decree regime, including court liaison, supplementary-evidence responses, and procedural escalation. Critical for applicants who built their plans around the pre-decree flexible rules.
Investment Citizenship Program pre-launch advisory
For high-net-worth clients targeting the announced 2026-2027 Investment Citizenship Program: advisory on likely qualifying sectors (energy, agriculture, technology, tourism), structuring of US$500k+ investments for when the program opens, and early-filing preparation.
Inversionista residency (US$100-200k)
For applicants using the Inversionista residency track: full investment structuring in an Argentine business or real-estate asset, DNM-compliant investment-verification documentation, and initial residency-permit filing on the qualifying investment. Typically faster initial residency than Rentista.
Spouse / parent fast-track
For spouses of Argentine citizens or parents of Argentine-born children: optimised fast-track documentation around the 2-year-from-marriage rule (spouses) or the immediate parent rule (parents), which are partly shielded from Decree 366/2025's no-departure strictness.
Argentine tax-residency planning
Argentine citizenship plus 2-year continuous residency creates Argentine tax residency. Structured advisory on the progressive 5-35% personal income tax, wealth tax (Impuesto sobre los Bienes Personales), and the now-common "no-movement" tax-treaty workarounds with US / UK / Spain / Italy.
Mercosur mobility onboarding
Structured advisory on practical Mercosur benefits: Brazilian, Paraguayan, and Uruguayan freedom of movement under the Mercosur Residence Agreement (MERCOSUR Residency Agreement), Argentine-passport treatment in Chile under the separate bilateral framework, and commercial benefits under the Mercosur Common External Tariff.
Frequently asked questions
What clients actually ask about Argentine fast-track naturalisation — with explicit focus on Decree 366/2025, the no-departure rule, and the grandfathering framework.
What changed in May 2025 under Decree 366/2025?
President Javier Milei signed Presidential Decree 366/2025 materially tightening the 2-year residency rule. Three main changes: (1) the 2 years must now be continuous with no departures from Argentine territory — any departure resets the clock to zero; (2) applications are now handled administratively by the Dirección Nacional de Migraciones (DNM) rather than federal courts; (3) applications filed with federal courts before May 2025 are grandfathered under the pre-decree regime.
What counts as a departure that resets the clock?
Any exit from Argentine territory, regardless of duration. A weekend trip to Uruguay, a day-trip to Brazil, a business trip to the US, a family visit home, or even a medical evacuation to a neighbouring country all reset the 2-year clock. This is stricter than any comparable naturalisation framework in the Americas. Plan accordingly.
Am I grandfathered if I filed before May 2025?
Yes, if your citizenship application was filed with the federal courts before May 2025. Pre-decree filings continue under the previous regime, which interpreted the 2-year continuous-residence rule more flexibly to permit short absences. Liberty Mundo's pre-decree continuation service maintains your file on the grandfathered track through completion.
What about the new Investment Citizenship Program?
President Milei announced a new Investment Citizenship Program expected to launch 2026-2027, with investments from US$500,000 or more in qualifying sectors (energy, agriculture, technology, tourism) potentially waiving the 2-year residency requirement entirely. Implementing regulations are still being drafted. Liberty Mundo offers pre-launch advisory for high-net-worth clients preparing for filing day.
Do I need to speak Spanish?
Not formally. Spanish proficiency is assessed informally at the DNM intake interview — no formal DELE exam required. Conversational ability to discuss everyday topics and basic Argentine civic knowledge is sufficient. Most applicants with 2 continuous years of Argentine residence naturally develop sufficient Spanish through daily life.
Can I keep my US / UK / other citizenship?
Yes. Argentina fully permits dual and multiple citizenship without restriction. No renunciation of your existing US, UK, Canadian, Australian, EU, Israeli, or other nationality is required at any stage. A key advantage over Nicaragua's post-January-2026 renunciation-required regime.
What about spouses of Argentines or parents of Argentine-born children?
Spouses of Argentine citizens qualify for naturalisation after just 2 years of marriage with residence in Argentina — the 2-year requirement is measured from marriage, not from residence-permit start. Parents of Argentine-born children qualify on an accelerated basis. Both are partly shielded from Decree 366/2025's no-departure rule in practice, with more flexible residence interpretation.
What does the service cost?
Liberty Mundo's typical fee for Argentine fast-track naturalisation is US$4,500 covering Decree 366 impact analysis, residency-permit filing, 2-year no-departure tracking, DNM citizenship filing, DNI, and passport application. Pre-decree court continuation is a separate US$3,500 add-on. Investment Citizenship Program pre-launch advisory is US$8,500.
How long does the process take?
2 years of no-departure residency plus 12-18 months for DNM administrative review post-decree, or 2 years plus 24-36 months for court-based processing under the pre-decree regime. Total end-to-end timeline: 3-3.5 years post-decree, 4-5 years pre-decree (grandfathered).
Where can I travel visa-free on the Argentine passport?
Approximately 172 destinations visa-free or visa-on-arrival — the strongest Spanish-speaking South American passport. Coverage includes the UK (ETA), full Schengen, US (ESTA from December 2025 reinstated), Canada (eTA), Japan, Singapore, Russia, Israel, and most of Asia and Africa. Full Mercosur passport rights to live and work in Brazil, Paraguay, Uruguay, Bolivia, Chile, and Peru.
Will I pay Argentine tax?
Argentine citizenship plus 2-year continuous residency creates Argentine tax residency during the qualifying period. Progressive 5-35% personal income tax on worldwide income for residents, plus a wealth tax (Impuesto sobre los Bienes Personales) on global assets. After completing naturalisation, Argentine citizens living abroad pay no Argentine income tax on foreign-source income unless they maintain Argentine tax residency.
How does Argentina compare to other fast-track options?
For applicants who can commit to 2 continuous years in-country: Argentina's ~172-visa-free passport is the strongest in the Spanish-speaking Americas, so it is typically the best route. For applicants needing travel flexibility during residency: Dominican Republic Law 1683 investor (6 months, ~75 visa-free) or Paraguay (3 years with flexible absences, ~146 visa-free) are better. Honduras 1-year Central American track is incomparable (nationality-specific).
Ready to check your Argentine fast-track eligibility?
Decree 366/2025 fundamentally changed the Argentine fast-track calculus — the 2-year rule is now strictly enforced with no departures permitted, and applications have moved from federal courts to the DNM. For applicants who can genuinely commit to living continuously in Argentina for two years, the route remains the shortest path to the strongest Spanish-speaking Latin American passport (~172 visa-free, Mercosur mobility, G20 diplomatic weight). For applicants with pre-May-2025 court filings: grandfathered continuation is available under the pre-decree regime. Submit an application and a senior advisor will come back within twenty-four hours with a personalised decree-impact analysis, a residency-track recommendation, and a candid view on whether Argentina naturalisation is your best route — or whether Dominican Republic investor, Paraguay, or the upcoming Investment Citizenship Program better match your profile.
