Compare Residency and Citizenship in South America

Curious about which country is the fastest and easiest to get Citizenship in South America?
Here’s a breakdown of the main options:

When considering moving to South America, the choice of country can affect how quickly you can get permanent residency, the path to citizenship, and the flexibility to live there with or without exit and re-entry restrictions.

Argentina - Fastest but Strict Residency Rules

Speed to Citizenship: Fastest in the region. After two years of approved residency, you can apply for naturalization, making it 3-4 years in total.

Requirements: Must remain in Argentina without any extended exits under the new regulations announced by the administration of Javier Millei.

Drawback for Family Members: Argentina does not grant citizenship or passports to children under 18 years of age.

Best for: Applicants seeking rapid citizenship with a stable passive income, particularly through the Rentista program (passive income).

Flexibility: Residency rules are strict, meaning you must stay full-time during the residency period before applying for citizenship; otherwise, the countdown toward citizenship will reset to zero.

Brazil - Best for Citizenship by Baby Birth

Speed to Citizenship: Having a child born in Brazil or being married to a native Brazilian can reduce the Brazilian citizenship period to 3-4 years. Other programs are slower, typically taking 5-6 years.

Requirements for other residency pathways:

– Four years of temporary residency (other programs).

– One year of permanent residency (by marriage or by baby birth).

– Citizenship processing (1-2 years).

– Must reside approximately 9 months per year to maintain residency (a little flexible than Argentina).

Family Benefit: Children as young as 10 can eventually obtain a Brazilian passport.

Best for: Applicants looking to set up a business in Brazil, obtain an invitation letter from their own company, have a baby born in Brazil, receive flexible permanent residency, and apply for citizenship after one year of permanent residency. Foreign children minor 10 years old who came with their parents can obtain a temporary passport until age 18 and obtain a permanent passport upon reaching 18 years old.

Paraguay – Least Requirements for Residency

Citizenship: With an investment of $70,000 USD or more, you can obtain three years of super-flexible permanent residency, then apply for Paraguayan citizenship by Naturalization, total making 5-6 years. 

Requirements:

– Hire five local residents during the investment period to maintain permanent residency eligibility for three years, and then apply for Paraguayan Citizenship. 

– For investments below $70,000, temporary residency is available, followed by permanent residency and eventually citizenship.

Advantages:

-Very low taxes (approx. 10% (VAT)), making it attractive for business owners.

– Flexible stay requirements – part-time presence is sufficient.

Best for: Investors and entrepreneurs seeking low-tax, flexible residency while still aiming for Paraguay citizenship.

Uruguay - Longer Process, but with a Stable Economy

Speed to Citizenship: Standard is 5–6 years (for singles), reduced to 3–4 years of permanent residency if staying with family.

Requirements:

– Stable income of $1,500 USD per month (can be salary, dividends, rent, etc.).

– Clean criminal record.

Advantages:

– Highly stable economy, Latin American Switzerland

– Offers a 10-year tax holiday for newcomers or 7% flat lifetime income tax. 

– Can set up companies remotely and possibly open bank accounts remotely (need confirmation with HSBC banks in Uruguay).

Best for: Families or retirees seeking stability, tax benefits, and quality of life.
