Countries around the world offer foreign nationals the chance to become permanent residents and obtain a second passport, often leading to dual nationality, through various means. Some of which include jus sanguinis (citizenship by descent), naturalization, jus matrimonii (marriage), citizenship by investment, and more.

Second citizenship is a legal status in which an individual is legally recognized as a citizen in two countries at the same time. This means the person has rights and responsibilities to each of the countries for which they hold passports.

This guide will take you through everything you need to know about acquiring additional citizenship, including:

What is second citizenship?

Second citizenship or dual citizenship refers to when someone holds legal citizenship in two or more countries simultaneously. It allows individuals to enjoy the rights and responsibilities granted under each country’s dual nationality law.

The Global Intelligence Unit’s report, “The Transformation of Citizenship” has seen perception shift regarding dual citizenship. It used to only be seen as tied to political allegiance but it is now recognized as a strategic asset.

This shift around dual citizenship aligns with trends in global mobility and personal security, especially as a second foreign passport can offer both freedom and protection in volatile times.

It offers people, especially high-net-worth individuals (HNWIs), greater international mobility, access to better economic opportunities and a safety net in times of uncertainty.

What are the benefits of second citizenship?

Hand holding up a passport in front of world map - Benefits of dual citizenshipOnce your dual citizenship is official, it comes with many benefits. Especially since you get the same or similar rights as an “original” citizen. These benefits include:

  • Increased global mobility: A second passport can significantly expand your travel options. It allows you to visit, work and even live in more countries without the need for a visa, which simplifies business and leisure.
  • Access to education and healthcare: Dual citizenship can grant you access to top-quality healthcare systems and educational institutions. This has the potential to improve your quality of life and offer better opportunities for you and your family.
  • Family benefits: When you obtain second citizenship through investment, it often extends to immediate family members. This grants them the same benefits, including freedom of travel, the right to live and work in the country, and access to education and healthcare.
  • Business opportunities: Gain access to international markets and financial systems, as well as potential taxation advantages, such as lower income tax rates or exemption from foreign asset reporting in some countries.
  • Property ownership: With dual citizenship, you have the right to own and rent property in both countries.
  • Enhanced security: When political instability or economic hardship happens in your country of origin, dual citizenship provides a safety net for you and your family.
  • Right to vote: As a second citizen, you can vote in elections as well as hold governmental positions.
  • Consular protection: A second passport grants access to consular services from both countries, enhancing protection while traveling or working abroad.

How to get a second citizenship?

Dual nationality laws have evolved significantly since the 1930 Hague Convention attempted to standardize citizenship rules and reduce statelessness globally.

Since then, six common ways to get dual citizenship have evolved worldwide and they include birth, naturalization, marriage, descent, investment and exception. Here’s a breakdown of each:

1. Citizenship by Birth

If you were born in a foreign country that grants citizenship by “jus soli” (right of soil), you may hold a claim to acquire citizenship based on simply being born in the country. Typically, when a nation practices jus soli children born within their territory automatically acquire citizenship.

Citizenship by birth is offered either restricted or unrestricted. When there’s no restrictions on citizenship by birth, it means there are no conditions on the parents’ legal status so the child can become a citizen even if the parents are foreign nationals or undocumented at the time of birth.

Restricted citizenship by birth, on the other hand, means certain conditions must be met, generally related to the parents’ nationality, residency or citizenship status, or legal immigration status.

2. Citizenship by Descent

Citizenship by descent is commonly known as “jus sanguinis” (right of blood), whereby an individual is granted citizenship or has the right to claim citizenship through a blood relative who holds citizenship in the country. The acquisition of dual citizenship is based on familial connection rather than place of birth.

These are some of the general conditions of the countries that offer Citizenship by Descent:

  • Direct line of descent: Most countries require a direct connection, such as a parent or grandparent, to claim citizenship.
  • Unbroken line of citizenship: If an ancestor renounced their citizenship, this may invalidate the claim.
  • Proof of ancestry: Applicants must provide birth certificates, marriage records, and other documents proving their connection to the country.
  • Residence and language requirements: Some countries, like Hungary, may require language knowledge or proof of ties to the government (e.g., cultural connections).

Popular countries that offer Citizenship by Descent include:

  • Italy
  • Ireland
  • Poland
  • Germany
  • Greece
  • Hungary
  • Portugal
  • Spain

3. Citizenship by Marriage

Citizenship by marriage refers automatically gaining citizenship in a country by marrying someone who is already a citizen. It has similar conditions to naturalization as there’s often specific requirements that need to be met and a period of residency.

It is often a more streamlined pathway to dual citizenship as the residency period may be reduced and there are often no language proficiency requirements. This makes it a common and attractive option to pursue.

These are some of the countries with the shortest residency period for citizenship by marriage:

  • Dominican Republic: Six months
  • Brazil: One year
  • Spain: One year
  • Argentina: Two years
  • Portugal: Three years
  • Germany: Three years

4. Citizenship by Naturalization

Close-up of globe - Definition of second citizenshipCitizenship by naturalization refers to the legal process a person who is not born in a country can acquire citizenship. It involves the person fulfilling specific requirements.

It often entails obtaining a residence permit to transition to permanent residency before applying for citizenship status after completing the required period of residency. It also may come with a language proficiency test or the need to display knowledge of local culture and history.

Keeping those requirements in mind, these are some of the countries with the shortest naturalization periods:

  • Argentina Two years
  • Peru: Two years
  • Paraguay: Three years
  • Belgium: Five years
  • Sweden: Five years
  • Portugal: Five years

As part of the naturalization process, many countries require an Oath of Allegiance, along with language and cultural competency tests.

5. Citizenship by Exception

Citizenship by Exception is the process of acquiring accelerated citizenship at the discretion of a head of state or ruling government body.

There are no concrete guidelines for obtaining or awarding this type of fast-track citizenship; however, the decision usually revolves around making substantial contributions to the country’s development, be it economic, educational, or cultural.

Two great examples include:

  • United Arab Emirates: The UAE Executive Regulation of the Federal Law concerning Nationality and Passports introduced new criteria for granting citizenship based on exceptional merit. Experienced individuals in fields such as scientific research, the arts, and medical care may be offered UAE citizenship at the discretion of royal UAE authorities.
  • Serbia: The Republic of Serbia has a discretionary program that may grant Serbian citizenship by exception to individuals deemed to have contributed significantly to Serbian society. Considerations can include contributions to education, business, or the possession of substantial assets in the Republic.

This discretionary path is not standardized and falls outside traditional routes defined by most nationality laws.

6. Citizenship by Investment

A few countries have introduced formal Citizenship by Investment (CBI) programs, allowing individuals to acquire a second passport by investment and is a form of economic naturalization that bypasses traditional timelines.

These initiatives typically involve significant financial investments, such as real estate purchases, job creation, or contributions to specific economic sectors.

For instance, the Antigua and Barbuda citizenship by investment program is one of the most affordable dual citizenship programs, with a minimum contribution to the country’s National Development Fund (NDF) of $230,000.

Vanuatu’s citizenship by investment program stands out because it grants citizenship within 60 days to foreign nationals who contribute $130,000 to the country’s government fund.

You do, however, need to use your US passport when re-entering or leaving the United States.

The only potential downside might be conflicting obligations such as military service, jury duty, or dual taxation, depending on the laws of each country.

Frequently Asked Questions about Second Citizenship

What is second citizenship?

Second citizenship, also known as dual citizenship, is a legal status in which an individual is recognized by two countries as a full citizen simultaneously.

Second citizenship affords someone the same rights as any other citizen of the host country, including living and working in the country.

How much does it cost to get dual citizenship?

The cost of obtaining dual citizenship varies widely, primarily through Citizenship by Investment (CBI) programs. These involve investing in a country’s economy and costs can range from as low as $100,000 to as high as $2,500,000.

What is the cheapest second citizenship program?

Dominica and St. Lucia currently offer the most affordable dual citizenship programs, starting from $100,000 for a single applicant through a government donation.

What are the benefits of having a dual citizenship?

Dual citizenship offers benefits such as:

  • Greater global mobility through visa-free travel abroad
  • Access to better education opportunities and healthcare facilities
  • Diversification of financial and business opportunities
  • Personal security

What are the risks of obtaining a dual citizenship?

While dual citizenship has more benefits than risks, it can bring potential double taxation, restrictions on holding government jobs, and potentially less consular access in some jurisdictions.

How do I apply for a dual citizenship?

The process of obtaining dual citizenship varies from country to country and depends on whether you do so through naturalization, descent, marriage or investment.

It may require meeting residency requirements, passing naturalization tests, providing proof of ancestry under jus sanguinis, or making financial contributions under CBI programs.

Does the United States allow dual citizenship?

Yes, you can hold dual citizenship of the United States and another country provided that you:

  • were born in the United States and you have a parent that is a citizen of another country.
  • were born outside the United States to 1 or 2 parents that were U.S. citizens at the time of your birth.
  • naturalize as a U.S. citizen while keeping the nationality of another country.

Does the United Kingdom allow dual citizenship?

Yes, citizens of the United Kingdom can hold dual citizenship in another country without losing their British citizenship.

Can you have dual citizenship with Canada?

Yes, Canada allows dual citizenship, meaning Canadian citizens can acquire a second nationality without losing their Canadian status.

Also, foreign nationals can get Canadian citizenship while retaining original foreign citizenship status, provided their home country also permits dual nationality.

There is no requirement to renounce your existing citizenship when getting Canadian citizenship.

What are the tax implications of a dual citizenship?

Dual citizenship can potentially bring with it double taxation, meaning the individual is taxed on the same income twice.

However, some countries often form bilateral tax treaties or agreements to mitigate this. These may include provisions for tax credits or exemptions to prevent or reduce dual taxation.

Can people with Indian citizenship become dual nationals?

No, India does not allow dual citizenship. Under Indian law, acquiring foreign citizenship automatically results in the loss of Indian citizenship.

However, India offers an alternative called Overseas Citizenship of India (OCI), which provides many benefits but it is not equivalent to full dual citizenship.
