4 Types of Citizenship – Traditional Ways
Different countries offer varying pathways to citizenship acquisition. These include birth, descent, marriage, naturalization, and investment routes.
The pursuit of second citizenship has gained tremendous momentum in recent years.
Global mobility restrictions and economic uncertainties have driven individuals to seek alternative passports.
Understanding these pathways helps individuals choose the most suitable option for their circumstances.
Each method has distinct requirements, processing times, and associated costs. Some countries prioritize family connections while others focus on economic contributions.
The choice depends on personal background, financial capacity, and long-term objectives.
Citizenship acquisition traditionally follows four primary pathways that have existed for centuries.
Citizenship by Birth (Jus Soli)
Citizenship by birth (or Jus Soli) grants nationality to anyone born within a country’s territory.
This principle operates regardless of the parents’ nationality or immigration status. Countries like Argentina, Uruguay, and Canada follow this approach extensively.
Citizenship by Descent
Citizenship by descent (or Jus sanguinis) connects nationality to bloodline rather than birthplace. This method allows individuals to claim citizenship through their parents’ or grandparents’ nationality.
Italy, Poland, and Ireland are prominent examples of countries offering descent-based citizenship.
The process typically requires proving ancestral connections through official documentation.
Citizenship by Naturalization
Naturalization represents the most common pathway for foreign nationals seeking new citizenship. This process requires individuals to live in a country for specified periods.
They must demonstrate language proficiency, cultural integration, and law-abiding behavior.
Argentina offers one of the fastest naturalization processes at just two years.
Citizenship by Marriage
Marriage-based citizenship provides accelerated pathways for spouses of nationals. This route often reduces residency requirements and processing times significantly.
Countries recognize that family unity supports social cohesion and economic stability.
Argentina, Brazil, and Spain offer relatively straightforward marriage-based citizenship options.
What is the Meaning of Citizenship by Investment?
Citizenship by Investment (CBI) programs allow individuals to obtain nationality through substantial financial contributions.
These programs emerged in the 1980s to attract foreign capital and stimulate economic development.
Applicants typically invest in real estate, government bonds, or national development funds. The investment amounts vary significantly between countries and program types.
CBI programs offer the fastest route to second citizenship for qualifying investors. Processing times range from three to six months in most programs.
Successful applicants receive full citizenship rights, including passport issuance and voting privileges.
However, these programs require significant financial commitments ranging from $100,000 to over $1 million.
The due diligence process forms a critical component of all investment citizenship programs.
Applicants undergo extensive background checks covering criminal history, financial sources, and reputation. This process ensures program integrity and maintains international recognition of issued passports.
Rejected applications typically result from inadequate documentation or adverse background findings.
What Country is the Easiest to Get Citizenship?
Argentina consistently ranks as the most accessible for multiple pathways including birth and naturalization. The country’s liberal citizenship laws and efficient processing systems support this reputation.

However, the definition of “easiest” varies based on applicant profiles and chosen route.
Some countries provide citizenship essentially for free through birth, descent, marriage, or naturalization after residency — you do not need to purchase it, only meet the legal requirements.
By contrast, a separate category of nations only grant citizenship through Citizenship by Investment (CBI) programs.
CBI require applicants to make a qualifying financial contribution (such as real estate, government bonds, or donations) to buy a passport.
