Being born in a country or having parents who are citizens of a foreign country can lead to various implications regarding citizenship status, depending on the countries in question. If the country you are born in grants citizenship automatically by jus soli (right of soil), and at the same time your parents hold foreign citizenship in a country practicing jus sanguinis (right of blood), you may be eligible for dual citizenship and two passports.
Many people are already dual nationals, holding multiple citizenships through ties to a family member with a foreign nationality or by being born abroad. Another instance when individuals may obtain dual citizenship is through the naturalization process, where they live in the country long enough to gain permanent residency and qualify as naturalized citizens.
This may initially sound unusual, but it is more common than you think. So, what exactly is dual citizenship, and how can you get a second citizenship and foreign passport from a country that aligns with your goals and aspirations?
In this article, we’ll go over everything you need to know about becoming a dual citizen by taking a more in-depth look at birthright instances of dual citizenship, as well as the choice to obtain a second citizenship by naturalization or through investment programs.
If you’re ready to embark on the journey of obtaining multiple citizenship status, keep reading to learn which countries allow dual citizenship and those that require you to forfeit your current citizenship before receiving a foreign nationality.
What is dual citizenship, and why does it matter?
Dual citizenship, often called second citizenship, refers to the citizenship of a person legally recognized as a citizen of two or more different countries. This scenario arises as some countries have differing criteria for citizenship. For example, a child born in Canada receives Canadian citizenship at birth regardless of whether they moved abroad as a baby or the other nationality they hold.
However, not all countries allow dual citizenship, and if you inform your home country’s government of your desire to apply for dual citizenship, your request may be denied, or you could lose certain benefits or citizenship rights, such as land ownership or political rights. In these scenarios, you could be forced to renounce your citizenship or give up the citizenship of the other country.
That said, most countries recognize dual citizenship, allowing their citizens to have more than one nationality. Furthermore, many don’t specify precisely how many citizenships you can have, meaning you can legally hold double or even triple citizenship status.
Who can request dual citizenship?
There are different rules for many countries, but generally, you can request dual citizenship if both countries accept it. In other words, provided your home country recognizes dual citizenship as well as the new country where you plan to gain citizenship, you can legally acquire dual citizen status. But in what instances can you claim or gain the right to dual nationality?
Dual citizenship by birthright
Dual nationality through citizenship by birthright is one of the most common ways people become dual citizens. Individuals who gain British citizenship by naturalization but were born in the United States would be considered British citizens and US citizens, as the United States Constitution declares that any individual born on US soil is a US citizen at birth.
Dual citizenship by descent
Many people have claimed dual nationality by descent through a family member who has a foreign nationality. This practice is known as jus sanguinis, where the right to citizenship is based on the citizenship of blood relations in the direct line. If you hold citizenship by naturalization in Australia and have a grandparent born in Poland, you can acquire Polish citizenship by descent and gain dual nationality.
Dual citizenship by naturalization
Suppose you’re a citizen of one country, but you live in another country with permanent resident status. In that case, your permanent residency and the time you’ve lived in the country may fulfill the country’s laws for granting citizenship by naturalization. Once you’ve acquired the other citizenship, you become a dual national.
Dual citizenship by marriage
Marriage to a foreign spouse is often a way individuals gain dual citizenship. If your spouse is a citizen of another country, you may have the right to citizenship with a reduced residency period. Spain’s naturalization process takes ten years for most foreign nationals; however, the spouse of a Spanish citizen can gain Spanish nationality after one year of residency.
Dual citizenship by investment
Immigrant investor programs have paved the way for those without birthright claims, familial ties, or non-permanent residents without years of residency in other countries to gain dual nationality by investing in a country’s economy. Citizenship by investment is a legitimate option for those seeking multiple citizenships, with the new country’s passport granted in as little as two months. Additionally, the eligibility requirements for citizenship by investment programs don’t include speaking the national language or obtaining permanent resident status with years of residency.
Dual citizenship by reclaiming citizenship
In years gone by, many individuals saw their citizenship revoked due to war or discriminatory immigration law based on religion, politics, and gender during that period. Several countries have amended arbitrary nationality laws, allowing a former citizen to reclaim their citizenship and acquire dual citizen status.
This applies to countries like Germany, where a recent amendment has opened the door for former German nationals who lost their German citizenship on political, racial, or religious grounds between 30 January 1933 and 8 May 1945 to apply for the restoration of their citizenship.
What if dual citizenship is not permitted?
Cases where being a citizen of two countries is not permitted means either your home country or the protentional host country only allows you to have one nationality. If you plan to acquire a second nationality, your country of original citizenship may demand you renounce your foreign citizenship or risk losing your current citizenship.
Should you have already gained citizenship in a second country, your original citizenship could be revoked. Similarly, suppose a prospective second country of citizenship does not permit dual citizenship. In that case, you will likely have to renounce your current citizenship before being granted the new one.
Certain countries have unique provisions that do not entirely forbid dual nationality. However, individuals who acquire a second nationality may receive a distinct status limiting their citizenship privileges, such as eligibility for public benefits or job roles that require security clearance.
Indian citizens who acquire a second citizenship are issued what is referred to as an Overseas Citizen of India card (OCI). This should not be mistaken for dual citizenship as it is more closely associated with permanent residency rather than citizenship. Indians who are assigned an OCI card essentially lose the rights of Indian citizenship, including consular protection, voting rights, and high-security clearance employment opportunities.
How Dual Nationality Laws are Changing
While not all countries permit dual citizenship, an increasing number are becoming receptive to the idea of allowing their citizens to hold multiple citizenships. Previously, South Africans were required to gain prior permission to become dual nationals by applying to retain South African citizenship. This was until a High Court decision deemed the rule unconstitutional in June 2023, as South African citizens automatically lost their birth citizenship when acquiring citizenship in another country.
Naturalized citizens of Germany had to renounce their original citizenship and those held from any other country before they could acquire German citizenship. However, in August 2023, the German federal government endorsed a proposed law granting new German citizens the ability to retain their original citizenship and obtain dual nationality, subject to final review.
Dual Citizenship versus Dual Nationality: What's the difference?
Dual citizenship and dual nationality are often used interchangeably, but there is a subtle distinction between the two terms.
Dual Citizenship | Dual Nationality |
Dual citizenship refers to the legal status of an individual who is recognized as a citizen by two different countries. This means the person has the rights and privileges of citizenship in both countries, which may include the ability to live, work, vote, and access government services in either country. | Dual nationality, on the other hand, is a broader term that encompasses the concept of holding citizenship in more than one country. It doesn't necessarily imply that the individual enjoys the full rights and privileges of both citizenships, but simply acknowledges that they are recognized as a national by multiple countries. |
The Advantages of Having more than one Citizenship?
There are many benefits to holding dual citizenship, with dual citizens receiving the benefits and privileges that each country has to offer. Dual citizens can have the right to vote in two countries, and one of the most significant advantages is holding multiple passports.
Here are some of the key benefits of dual citizenship:
Dual citizenship
Dual nationality comes with the power to hold a foreign passport. This provides rights and privileges in two countries, opening up the options for places to live, work, and study.
You can completely immerse yourself in a second culture, not as an outsider, but as an acknowledged member of that society. Dual citizenship enables you to fully engage with the traditions, languages, and customs of both countries, nurturing a profound sense of belonging and acceptance.
Enhanced travel freedom
Gaining a second passport ranking high on the Global Passport Index increases travel freedom and flexibility. Increased visa-free access or visa-on-arrival options are available with dual nationality and two passports, allowing greater exploration and experiences in different parts of the world without restrictions or lengthy visa processes.
For example, a Caribbean passport, like a Grenadian passport, offers visa-free travel to China, whereas US citizens require a visa. EU passports provide freedom of movement throughout the European Union and extensive visa-free access to destinations worldwide.
Security and safety
A foreign passport could prove invaluable during political turmoil, social unrest, or unexpected crises. Should the situation in your home country deteriorate, dual citizenship offers consular protection and the option to seek refuge in a safer country without enduring the bureaucracy of immigration services and procedures.
Expanded financial opportunities
Two passports can expand the door to investing in lucrative international investments and global markets. Dual nationality can empower investors to establish and grow their businesses in countries providing taxpayers with advantageous tax regimes or incentives.
Countries like Cambodia and the UAE restrict foreign individuals from owning property or land. Many foreign governments also limit foreign property ownership to designated areas. Dual citizenship in these countries lifts these limitations, directly increasing investment opportunities.
Personal and family protection
Dual nationality provides you and your family with added protection. Multiple citizenship status can guarantee access to healthcare, education, and legal protections in another nation that only citizens have the right to, offering a safety net and peace of mind for the future.
Privacy and freedom
Dual citizenship can contribute to enhanced privacy and personal freedom. Dual nationals with alternative passports diversify their identities, mitigating risks tied to depending solely on one passport and the potential vulnerabilities they may come with.
Dual passport holders can conduct business with greater discretion through gateways to countries with more robust privacy regulations and financial systems, ensuring the protection of personal information and financial assets.
Increased privacy and freedom empower dual citizens to navigate international matters with increased independence and guarantee the confidentiality of their personal and financial affairs.
How to Become a Dual Citizen
Apply for birthright citizenship: If you were born in a country that practices jus soli, you’re entitled to citizenship by birthright.
Apply for citizenship by descent: If your parents, or in some cases grandparents, are citizens of certain foreign countries, you may have the right to become a dual citizen by descent.
Apply for citizenship by naturalization: Gaining a residence permit in a new country and completing the minimum residency period for naturalization can fulfill the eligibility requirements to receive citizenship.
Apply for citizenship by marriage: An official marriage certificate can reduce the required residency period for citizenship by naturalization.
Obtain dual citizenship by investment
Citizenship by investment has streamlined the process toward dual citizenship. Several countries now offer investment programs allowing foreign nationals to gain multiple citizenship status and build a passport portfolio in exchange for a direct investment. A key benefit is that investors can achieve dual citizenship through investments that offer dual benefits, like real estate acquisitions or establishing businesses.
Dominica citizenship
One such country is Dominica, offering dual citizenship in exchange for a qualifying investment. Individuals who meet the Dominica citizenship by investment program’s criteria are offered a second passport in three short months, with no visit to the country required. Investments start from $100,000.
Vanuatu citizenship
Similarly, Vanuatu has a second passport program that also offers foreign investors the chance to become dual nationals. The required contribution for Vanuatu’s citizenship by investment program is $130,000 for a single person and $150,000 for a couple. No visit is necessary to acquire dual citizenship and a passport. To top it off, Vanuatu has no income tax, wealth tax, capital gains, or inheritance tax.
Portuguese citizenship
Portugal allows dual citizenship, so you won’t have to relinquish your original nationality. Acquiring Portuguese citizenship through naturalization is a standard route for foreigners, as the required residency period is just five years, in contrast to countries like Spain and Italy, which have ten-year residency requirements.
Typically, applicants start by applying for Portugal’s Golden Visa program, which invites investors to contribute to the nation through various investment options and, in return, grants them legal residency in the country. With five years of residency, you are eligible for second citizenship and a Portuguese passport.

Frequently asked questions about dual citizenship
How do I get dual citizenship?
There are a few ways to get dual citizenship, including:
- Being born in another country that grants citizenship by birthright
- Applying for second citizenship by descent through a dual citizen family member
- Being married to a foreign national and obtaining dual citizenship by marriage
- Living in a foreign country for a specified period to qualify for dual citizenship by naturalization
- Investing in a country to become a dual national by investment
Bear in mind that both countries must allow dual citizenship for you to obtain dual citizen status.
Is dual citizenship recognized in the US?
The United States does not formally recognize dual citizenship, but it does not prohibit US citizens from obtaining citizenship in two countries. This means US nationals can obtain dual or triple citizenship without losing their US citizenship.
Is there a downside to dual citizenship?
There are more pros than cons of dual citizenship. However, the drawbacks of holding dual citizen status will depend on which two countries’ citizenship is held. For example, the United States imposes citizenship-based taxation, meaning US citizens owe taxes to the US government, regardless of their second citizenship or whether they’re permanent residents of another country.
Obtaining dual citizenship in certain countries may also come with the risk of mandatory military service.
Does dual citizenship affect social security benefits?
Social security benefits largely depend on the countries in which you have citizenship. For example, assuming you retain US citizenship, you can keep your social security benefits or options in both the United States and the other country, as long as the other country permits it. Dual citizenship rules may differ from country to country, so keep this in mind.
Does dual citizenship last forever?
Adult passports typically have a ten-year validity; however, when discussing dual citizenship, citizenship is generally a permanent status and, in many countries, can be passed down to future generations.
While there are often revisions to citizenship laws, increasing globalization has prompted many countries to relax their stringent rules prohibiting dual citizenship.
What is the easiest country to get dual citizenship?
The easiest countries to get dual citizenship as a foreign national are Caribbean nations that offer citizenship by investment. These include:
- Antigua and Barbuda
- Dominica
- Grenada
- St Kitts and Nevis
- St Lucia
While other countries also have attractive routes, these are considered to have some of the fastest and most straightforward paths to dual citizenship. To get citizenship in any country, you should first consult the citizenship and immigration services in that country.
Do dual citizens pay taxes in both countries?
Whether you need to pay tax in both countries will depend on the country and the agreements in place. In some cases, you will have to pay taxes in both countries. For example, if you are a citizen of the United States, you are subject to citizenship-based taxation, not on your place of second residency.
Some countries have double taxation treaties, allowing dual citizens to avoid paying taxes on the same income to both countries. Many governments also offer attractive tax benefits for foreigners entering the country.
What is an example of multiple citizenship?
An example of multiple citizenship is a person born in the United States who acquired US citizenship by birthright, obtained Canadian citizenship after becoming a permanent resident, and claimed Italian citizenship through descent from an Italian grandparent.
If I am a citizen of multiple countries, do I need to fulfill military service in both countries?
If military service is mandatory in the countries where you hold dual citizenship, you are required to follow the rules in place in both countries. Certain countries with compulsory military service offer exemptions for dual citizens with permanent residence status in a foreign country.
