When people think about obtaining a second nationality, they often imagine a process taking five, seven or even ten years. Argentina presents a very different possibility. Under Argentina’s current citizenship law, an adult foreign national can apply for Argentine citizenship after completing two years of continuous and legal residence in Argentina.

The Two-Year Citizenship Opportunity

The basic rule sounds remarkably simple:

Obtain qualifying legal residence → live continuously in Argentina for two years → become eligible to apply for naturalization.

However, there is an extremely important condition. Under the current law, “continuous residence” means remaining inside Argentina for the entire two-year qualifying period without travelling outside the country. This opportunity may be attractive, but it requires serious commitment.

The two-year mark also does not mean that a passport is automatically issued after exactly 24 months. It means the applicant becomes eligible to submit the citizenship application, after which the authorities must process and approve it.

A Major Change: Citizenship Applications Are Now Digital

Argentina has also modernised the process. Since October 2025, naturalization applications have been handled by the Dirección Nacional de Migraciones, with eligible foreigners able to initiate the process digitally. Previously, naturalization applications went through Argentina’s federal courts.

This is an important development for foreigners considering Argentina as a long-term destination.

Temporary Residence Can Be Enough

An applicant does not necessarily have to wait until obtaining permanent residence before pursuing citizenship. Argentina’s government states that foreigners holding temporary or permanent residence can initiate naturalization once they meet the citizenship-law requirements.

This creates an unusual situation for some non-MERCOSUR nationals:

• Ordinary permanent residence can generally require three years of temporary residence for a non-MERCOSUR citizen.
• Citizenship eligibility, by contrast, can potentially arise after two qualifying years.

In other words, under the current rules, citizenship eligibility can potentially arrive before ordinary eligibility for permanent residence.
