Types of Citizenship

First, let’s discuss the various types of citizenship. Any of the following methods can help you become a citizen:-

1. Investment-based citizenship.

Certain countries grant citizenship through investment. The amount may vary between countries based on factors such as the type of investment and the number of applications. However, certain countries do provide Golden Visas.

With a minimum investment of $90,000, São Tomé and Príncipe has the most affordable citizenship by investment program as of 2026. St. Lucia, Grenada, and Dominica are some of the most common countries that provide citizenship based on investment.

2. Citizenship based on Descent.

One may be eligible for citizenship by descent if at least one parent is a citizen of that country or if the child was born abroad to a citizen of that country. Ancestors are also eligible for citizenship via descent.

Citizenship by descent is easily granted in the following countries:

  • Ireland
  • United Kingdom
  • Spain
  • Romania
  • Portugal
  • Luxembourg
  • Israel
  • Lithuanian
  • Greece
  • Armenia
  • Germany
  • Latvia

3. Citizenship by Birthplace (Birthplace Citizenship)

If you were born in the country, you are a citizen by birth. This is independent of the citizenship of your parents. Nonetheless, there are two types of citizenship by birth: “Jus Soli” and “Jus Sanguinis.” According to the principle of jus soli, or right of birth, a person can get citizenship based on their place of birth, irrespective of their parents’ nationality.

However, according to the kinship concept known as Jus Sanguinis, a person must have at least one parent who is a citizen of that country. France, Germany, Greece, Malta, Portugal, and Spain are among the nations that have accepted the Jus Sanguinis principle.

In this regard, the ten nations that accepted the Jus Soli concept and easily grant citizenship by birth are as follows:

  • Canada
  • America
  • Barbuda and Antigua
  • St. Kitts and Nevis
  • Mexico
  • Australia
  • Brazil
  • St. Lucia
  • Dominica
  • New Zealand

4. Obtaining Citizenship by Naturalization.

If you meet specific conditions and are eligible for citizenship in that country, you can apply for naturalization. However, the procedures that are required depend on the unique circumstances and requirements of each country. The following procedures must be used to apply for naturalization and become a citizen of another country:

Living in a Nation Continually for a Set Amount of Time: Every nation has several kinds of residency permits, which can be acquired by marriage, work, or student status. If you use these residence permits to live there regularly for a set period of time, you may be eligible to petition for citizenship in that country.

Obtaining Exceptional Citizenship: Certain nations may offer exceptional citizenship to those who have made outstanding contributions to science, technology, culture, or sports. Malta, for instance, provides the opportunity to become a citizen based on merit.

5. Marriage-Based Citizenship

If you meet the legal requirements, marriage can also grant you citizenship in several countries. Usually, a number of years of national residency and language tests are necessary.

Argentina, Brazil, Mexico, Portugal, Italy, Belize, and Spain these countries either demand a certain amount of residency or grant citizenship directly through marriage.

Top tip – No country gives citizenship without the legal requirements and documentation, so always keep all your documents ready before applying for any country’s citizenship.

What has changed at this point?

The internet is filled with a lot of outdated advice. Once-promising “fast-track citizenship” countries have quietly extended deadlines, tightened regulations, or implemented covert residency restrictions. Simultaneously, a new set of countries has formed, providing faster, more intelligent, and more affordable pathways that the majority of candidates are still unaware of. Several data points that have been extensively shared throughout time on internet portals are now out of date. Important adjustments for 2026:

Peru– Law No. 32421 (August 2025) extended the naturalization period from two to five years. Peru is not a fast-track country anymore.

Dominican Republic– For most citizens, the stated 2–3-year road actually means 5 years of temporary residency plus 2 years of permanent residency (7 years total from arrival) (Reference-https://migracion.gob.do/en/servicio/temporaryresidence-rt-9/).

Argentina: For the duration of two-years, Decree 366/2025 now mandates constant physical presence. Stricter than the pre-2025 regulations, every departure resets the clock.

Portugal Golden Visa: Most foreign nationals may have a 10-year naturalization period under proposed 2025 law reforms. The current 5-year regulations are still in force even if changes are being considered.

Germany: After earlier modifications, the country’s Skilled Immigration Act pathway currently takes five years to obtain permanent residency, rather than the eight to ten years mentioned in some older sources.

Cambodia CBI: As of December 2025, the investment threshold has been raised to $1–$3 million, which would significantly affect affordability.

Click to know what happens when you arrive for the first time at the Canadian border on a study and work permit in 2026

1. Brazil

One of the most attractive marriage-based citizenship pathways in the Americas is provided by Brazil. Within a year of getting married, foreign spouses of Brazilian citizens are eligible to petition for citizenship. Depending on the applicant’s country of origin and unique circumstances, naturalization is possible for employment and study pathways after two to four years of stay. Dual citizenship is accepted in Brazil, and the passport allows entry into more than 170 nations without a visa.

2. Paraguay

Paraguay has an official three-year naturalization period for employment, education, and marriage. South America and the Schengen Area are accessible without a visa with a passport, and the country has a somewhat easy residency process. Dual citizenship is also allowed in Paraguay. Although the process is simple, candidates should be aware that, in comparison to European options, Paraguay’s passport has a relatively low ranking on global mobility rankings.

3. Ireland

Ireland offers a clear road to citizenship in five years through its targeted approach to skilled immigration, especially in ICT, engineering, and life sciences. Professionals in high-demand positions may speed up their residency under the country’s Critical Skills Employment Permit. A percentage of the study years can be applied toward residency for international students. The road is shortened to three years of legal residency if you marry an Irish citizen. One of the easiest ways to obtain citizenship in Europe is still through Ireland’s citizenship by descent scheme (by an Irish parent or grandparent).

4. Turkey

Depending on resources, Turkey offers two completely distinct citizenship timelines. Five years of lawful residency are required for the traditional citizenship process. Applications for the Citizenship by Investment (CBI) program, the largest direct-citizenship program in the world, are processed in less than three months for investors who buy qualified real estate valued at least $400,000. The Provincial Directorate of Istanbul implemented same-day biometrics for CBI candidates as of February 2026. Another important strategic advantage of Turkish citizenship is that it makes one eligible for the U.S. E-2 Treaty Investor Visa. The five-year standard timetable is applicable for study and employment naturalization.

5. Canada

Although Canada’s citizenship process is well-organized, obtaining permanent status is a requirement. The necessary number of days of physical presence can be collected over three to five years by skilled workers through Express Entry and overseas graduates through the Post-Graduation Work Permit (PGWP) route. After three years of permanent residency, foreign spouses of Canadian citizens are entitled to become citizens.

A December 2025 modification to Canada’s Citizenship Act (Bill C-3) also revived citizenship eligibility for some people and their descendants who had been denied it under prior laws.

6. Argentina

As of 2026, Argentina remains the world’s fastest naturalization destination. After merely two years of continuous physical presence, foreign nationals who obtain legal residency—whether through marriage, a work permit, or a student visa—can apply for citizenship. A large number of people can apply for the nation’s Rentista visa, which requires confirmation of a steady foreign income of about $2,000 per month.

Importantly, Argentina provides visa-free travel to 172 locations, including the Schengen Area, and permits dual citizenship without any restrictions. Applications can be submitted the day following the wedding day, and processing usually takes one to two years, making the marriage pathway the fastest in the world.

7. Spain

Spain’s citizenship by marriage pathway is one of the quickest in the EU, requiring only one year of legal residency following marriage to a Spanish resident. Due to historical relations under the framework of the Iberoamerican Treaty, Spain additionally shortens the typical naturalization period for citizens of Latin America from ten years to just two years. Spain is mainly competitive for marriage candidates and citizens from former Spanish territory because students and skilled professionals from other regions must meet the regular 10-year residency requirement for naturalization.

8. Portugal

One of the most well-liked residency-by-investment alternatives in Europe is Portugal’s Golden Visa scheme, which requires qualified investments in cash, cultural enterprises, or the creation of jobs. After five years of having a residency visa, one is eligible for citizenship; importantly, the Golden Visa does not require constant physical presence in Portugal during that time. The five years of residency required for naturalization can also be acquired by skilled professionals and international students.

Portugal is ranked 28th in the world by the 2025 Global Passport Index.. Note: The present 5-year rule is still in effect as of April 2026; pending legislative changes could increase the naturalization time to 10 years.

9. Germany

Germany’s Skilled Immigration Act was modified in 2024, allowing eligible professionals to apply for permanent residency within five years instead of the previously specified eight to ten years. Germany’s ranking for work-based citizenship pathways is greatly enhanced by this. A part of study years may be applied to the residency requirement for international students.

In addition to three to five years of legal residency, completing an integration test, and demonstrating language proficiency are requirements for German citizenship by marriage. With visa-free entry into more than 190 countries, Germany’s passport continues to be among the strongest in the world.

10. Mexico

Mexico comes in at number ten with a two-year marriage-based citizenship track and a five-year naturalization road for workers and students. The country is strategically located, and its passport provides good regional movement throughout the Americas. For people who want to build a portfolio of passports, Mexico’s naturalization procedure is appealing because it is comparatively simple and requires no renunciation of previous citizenship.

 

Frequently Asked Questions

Vatican City, Liechtenstein, Switzerland, Japan, Austria, Qatar, United Arab Emirates, and Saudi Arabia are the hardest countries to obtain citizenship due to their extremely difficult requirements, strict residency rules, low approval rates, language requirements, or limited naturalization pathways.

Usually, no, because getting divorced does not automatically cancel your citizenship in most countries, like Canada, the United States, Australia, and many European countries. But it depends on how you obtained the citizenship. You can divorce at any time after becoming a U.S. citizen without losing your citizenship. However, if you divorce before applying, your waiting period to apply for naturalization increases.

Countries like Afghanistan, Syria, Iraq, Yemen, and Pakistan have the weakest citizenship because citizens of these countries often need visas for most destinations, while passports from countries like Singapore, Japan, or Canada allow much broader visa-free travel.

No. An OCI is not full citizenship. OCI stands for Overseas Citizen of India, offered by India to some foreign citizens of Indian origin. Despite the name, it is more like a long-term residency and travel status, not actual Indian citizenship.

Yes. Canada allows multiple citizenships, so a Canadian can legally have three citizenships or even more if the other countries involved also allow it. This can happen through birth in the country, parents from another country, and later naturalization in a third country. But if one of the countries does not allow dual/multiple citizenship, for example, India or sometimes Japan, then you may have to give up one citizenship or face restrictions.
