What Is Dual Citizenship?

Dual citizenship is a legal status where an individual is recognised as a citizen of two countries simultaneously. This status can offer numerous benefits, including enhanced global mobility and the ability to work and live in two countries. 

Today, approximately three-quarters of countries around the world recognise dual citizenship. The United Kingdom was a pioneer in encouraging a sense of belonging to both the broader British identity and the four nations within its union. The UK formally recognised dual citizenship beyond its borders in 1948. Other countries gradually embraced dual citizenship — Switzerland in 1953, Ireland in 1956, France in 1973, Canada in 1977, Italy in 1992, Brazil in 1994, Mexico in 1998, Sweden in 2001, and Australia in 2002. 

In this article, we will explore the various aspects, considerations, and implications of dual citizenship, including the benefits of dual citizenship, pathways to acquisition, which countries allow dual citizenship and tips on applying for dual citizenship. 

Advantages and Disadvantages of Dual Citizenship

What is dual citizenship - this question can’t be answered without considering all of its aspects. Dual citizenship offers significant advantages to individuals and their families, such as financial and geopolitical security. It can also be passed down to further generations. But along with rights and privileges, some important obligations must also be carefully weighed by those holding this status and wanting to apply.

Advantages of Dual Citizenship

• Global Mobility: Dual citizens often enjoy visa-free or visa-on-arrival access to a wider range of countries. This greatly enhances travel convenience, especially when using a dual nationality passport.
• Security: A second passport is a reliable backup option for political stability and safety in another country.
• Residency Rights: Dual citizenship provides the flexibility to live and work in two countries, allowing individuals to choose the best location for their personal and professional needs.
• Access to Public Services: Dual citizens can benefit from healthcare, education, and social services in both countries. 
• Business Opportunities: Holding dual citizenship can create new business and investment opportunities in both countries, often with fewer restrictions than foreign nationals.
• Taxation: Managing tax obligations in two countries can be more complicated, but typically can provide certain advantages to passport holders. 
• Political Rights: Dual citizens may have the right to vote in elections and even run for public office in both countries, which means they can influence governance in different places.
• Cultural Ties: Dual citizenship allows individuals to maintain strong cultural and familial connections with both countries. 
• Property Ownership: Dual citizens can own property in both countries.

Disadvantages of Dual Citizenship

• Legal Obligations and Conflicting Laws: Dual citizens are subject to the laws of both countries, even when there are conflicting laws, which might create challenges in areas such as taxation, inheritance, or divorce.
• Military Service: In some countries, dual citizens may be required to fulfil military service obligations.
• Bureaucratic Complexity, Cost and Time: Navigating the legal and administrative requirements of two countries requires increased time and effort and can be costly.

Financial Considerations in Dual Citizenship

What is dual citizenship when viewed through the financial lens? It is a status that can offer significant financial advantages, but it also introduces some complexities. 

• Tax Advantages: Some countries impose taxes on income earned within their territory, offering a significant advantage. While some dual citizens may face taxes in both countries, many nations have tax treaties that prevent double taxation. 
• Financial Flexibility: Dual citizenship can simplify international banking and open up diverse investment opportunities, providing financial security against economic instability.
• Wealth Protection and Inheritance Planning: Managing inheritance across two countries allows for strategic estate planning, ensuring that wealth is preserved and efficiently passed on to heirs.
• Retirement Benefits: Dual citizens can potentially benefit from social security agreements between countries, allowing them to combine work credits and optimise retirement benefits.

• Birthright Citizenship (Jus Soli)
• Citizenship by Ancestry (Jus Sanguinis)

Key Dimensions of Dual Citizenship

What does dual citizenship mean for business professionals and entrepreneurs?

• Access to Markets and Resources: Rules and regulations governing how businesses are established, operated, and taxed can vary significantly between countries, including in areas like corporate structures, licensing requirements, and labour laws. Being a citizen of two countries opens doors to cross-border entrepreneurship, providing access to markets, resources, and networks in both countries. 
• Expanded Employment Prospects: Dual citizens can work legally in both countries and also benefit from broader networking opportunities across professional and business communities.

What is dual citizenship when viewed through Social, Political, and Security Considerations

• National Identity: Holding dual citizenship often requires balancing your sense of identity and loyalty between two nations.
• Rights and Movement: International laws support dual nationality as a human right, ensuring freedom of movement and diplomatic protection in both countries. However, 
• Political and Security Implications: Dual citizens may encounter challenges, such as conflicting obligations or issues related to extradition or security clearances.

What is dual citizenship for children? 

• Automatic Acquisition: In many cases, children automatically acquire dual citizenship at birth if their parents are from different countries. For instance, a child born in the United States to French parents is automatically granted U.S. citizenship by birthright while also acquiring French citizenship through parents.
• Choice of Citizenship: However, dual citizenship is not always permanent for children. For example, in Japan, individuals with dual citizenship must choose one nationality before turning 22 years old.

Major Countries That Don’t Allow Dual Citizenship

What is dual citizenship in countries that don't allow it? How do major countries such as China, India, Saudi Arabia, Thailand, Vietnam, and Japan handle dual citizenship? Individuals often retain multiple nationalities through non-disclosure, acquiring a second nationality without reporting it to their home country. Others benefit from legal exceptions, like India’s OCI card.

• China: Chinese Nationality Law prohibits dual nationality, with foreign citizenship automatically nullifying Chinese nationality. Despite this, some citizens acquire foreign passports but risk severe penalties if discovered.
• India: India forbids dual citizenship. Citizens who adopt another nationality lose Indian citizenship but can apply for the OCI program. This grants privileges like living and working in India, though voting rights and public office are excluded.
• Saudi Arabia: Saudi law requires citizens to notify the government when acquiring foreign citizenship and may demand relinquishment of Saudi nationality. Non-disclosure is a common workaround but carries risks.
• Thailand: Thailand limits dual citizenship to children born abroad to Thai parents. Adults acquiring foreign citizenship must renounce Thai nationality, though enforcement is inconsistent, particularly for those avoiding government roles.
• Vietnam: Dual citizenship is prohibited, with few exceptions for individuals contributing to the state. Non-disclosure is a common method of retaining Vietnamese nationality alongside foreign citizenship.
• Japan: Japan requires citizens with multiple nationalities to choose one by age 22. However, many dual citizens maintain separate identities, using their Japanese passport domestically and another passport abroad.
• United States: While not formally recognising citizenship, the U.S. allows it, provided citizens comply with taxes and civic duties. Dual nationals are expected to prioritise U.S. citizenship.
