Definition: Dual Citizenship

Dual Citizenship is a legal state of a person holding two or more citizenships simultaneously.  Holders of Dual Citizenship can exercise the rights conferred to them at law in those countries in which they hold citizenship.  Malta allows dual citizenship, indeed multiple citizenships, and allows holders of other citizenships to acquire citizenship in Malta without renouncing their prior citizenships.

The concept of dual citizenship builds on the foundational concept of sovereignty.  Every country is sovereign in enacting the laws regulating citizenship and the conditions under which a person is granted, renounces or loses citizenship is strictly within the discretion of every state.

For a long time, many legislatures have treated dual citizenship as problematic and a legal state that should be avoided for its citizens. However, in recent years many countries have adopted a more favourable stance towards allowing their citizens to hold Dual Citizenship through relaxation of requirements for naturalisation or simply through allowing or recognising Dual/Multiple Citizenship without the need to renounce their original citizenship.

The Dual Citizenship Report

Following the publications of the first two editions of the Dual Citizenship Report, Chetcuti Cauchi has published the third edition of the Dual Citizenship Report, this time a global edition assessing the dual citizenship laws of over 100 countries globally.  The Dual Citizenship Report delves into whether a particular jurisdiction permits, limits, or else forbids its citizens from enjoying dual and multiple citizenship. Every country chapter is grounded on the feedback from citizenship lawyers from law firms worldwide who contributed their commentaries and analysis of dual citizenship laws in their country. 

Dual Citizenship globally 

Statistically, our dual citizenship studies reveal that 60% of countries surveyed allow dual citizenship, whilst only 20% of the countries entirely prohibit dual citizenship. The restrictive practice that naturalisation results in a withdrawal or loss of citizenship, has been widely discarded by many in favour of a more pro-dual citizenship stance. Moreover, there is only a small percentage of states which demand that a choice needs to be made by those born with dual citizenship, i.e. between their two citizenships, upon attaining the age of majority. 

European countries, as well as Latin America, North America, the Pacific and the Caribbean, constitute the majority of countries which allow dual citizenship. On the other hand, dual citizenship legislation in the Commonwealth of the Independent States and Africa are more diverse, however, Southeast Asia is considered as the most restrictive jurisdiction with regards to this matter. 

Countries which allow dual citizenship without any restrictions include Malta, Canada, Saint Kitts and Nevis, New Zealand, Saint Lucia, the United States, the United Kingdom and Cyprus. There are certain countries which do not explicitly refer to their dual citizenship laws, and as a result, they abstain from imposing any repercussions, resulting from the obtainment of another nationality. 

As shown from the Global report there are certain jurisdictions which although they permit dual citizenship, they might still impose specific limitations such as matters relating to public office. For example, Russia poses a restriction on those members elected for the Federation Council or else those which contribute in the editorial office of a broadcasting entity or a mass media. Various countries such as South Africa and Russia, only permit dual citizenship if the individual informs the authorities. 

On the other side of the globe, there are other jurisdictions which entirely prohibit dual citizenship and also hold that the attainment of another citizenship would result in the loss of their own citizenship. Some of such countries are Nepal, India, Ethiopia, Kazakhstan, Monaco and China. With regards to countries like Estonia, Japan and Indonesia, there is an exception for adult dual citizens or children under a certain age. However, once they attain the age of majority, such individuals have to decide on which citizenship to keep and which to renounce. 

There are other jurisdictions which prohibit dual citizenship, but which make expectations in certain cases, or which are subject to certain conditions, compromising international treaties with certain countries, or in cases of marriage or birth. With regards to EU countries such as Latvia, Bulgaria and Germany, dual citizenship is permitted in relation to EU member states, amongst other criteria. There are countries which have a set of dual nationality agreements in place. Some of such countries are Pakistan, Spain, Nicaragua and Honduras. Countries such as Norway, Austria, South Korea and Lithuania make allowances for dual citizenship for dual citizens either by marriage or birth, or both.

what's inside

Understanding the advantages, responsibilities, and global opportunities of holding two or more citizenships.

Dual citizenship allows individuals to hold nationality of two or more countries simultaneously, combining the rights, privileges, and responsibilities of each. This publication outlines how dual citizenship is obtained, which countries allow it, and the key benefits and obligations associated with holding multiple nationalities — from enhanced mobility to complex tax and legal compliance duties.

  • Dual citizenship laws vary by country and are determined by national legislation.
  • Some countries fully permit multiple citizenships; others restrict or prohibit them.
  • Dual citizens enjoy broader rights (travel, employment, property ownership) but may face dual taxation or military obligations.
  • Legal compliance and tax planning are essential to manage responsibilities across jurisdictions.
  • Strategic use of dual citizenship can enhance global mobility and family resilience.

Understanding Dual Citizenship

In a globalised economy, dual or multiple citizenship has become increasingly common among internationally mobile families, investors, and entrepreneurs.

A dual citizen holds the legal status of being a citizen of two or more countries simultaneously, benefiting from the rights of each while being bound by their laws.
However, not all countries permit or recognise dual nationality, and those that do often impose specific conditions, such as residence or renunciation requirements.

Dual citizenship can be acquired in several ways, depending on the laws of the countries involved.

How Dual Citizenship Is Obtained

Citizenship by Naturalisation

Acquired after long-term residence and compliance with local integration or language criteria.

Citizenship by Descent

Derived from having a parent, grandparent, or ancestor who was a citizen, depending on lineage laws.

Citizenship by Marriage

Granted to spouses of citizens after fulfilling residence or marriage-duration requirements.

Citizenship by Birth (Jus Sanguinis or Jus Soli)

Some countries grant citizenship by birth on their soil, others by descent from citizen parents.

Citizenship by Merit or Investment

Certain jurisdictions, such as Malta, allow citizenship through contribution or merit, following residence and due diligence under regulated frameworks consistent with EU law.

Do All Countries Allow Dual Citizenship?

Dual citizenship is not universally accepted.
Countries like the United States, Canada, the United Kingdom, Malta, and Australia allow multiple citizenships without automatic loss of the original nationality.
Others, such as South Korea, recognise dual citizenship under specific conditions, often linked to residency or family ties.

Conversely, China and India prohibit dual nationality; citizens must renounce their original citizenship when acquiring another.
Anyone considering a second citizenship must first confirm whether their home country recognises dual nationality — failing to do so could result in automatic loss of original citizenship or legal complications.

The Benefits of Dual Citizenship

Freedom of Travel

Dual citizens enjoy greater global mobility, holding multiple passports and gaining visa-free or visa-on-arrival access to a broader range of countries.
This facilitates business travel, education, and family relocation — a major advantage for frequent international travellers.

Employment and Business

Dual nationality expands professional and commercial opportunities.
Citizens may work, establish businesses, or invest freely in both countries without the need for work permits, business visas, or additional authorisations.

Political and Civic Rights

Dual citizens may vote, hold office, and participate in political life within each country of nationality, enjoying full civil rights and, in some cases, eligibility for public service roles.

Property Ownership and Investment

Ownership restrictions that apply to foreigners do not apply to citizens.
Dual citizenship therefore simplifies property acquisition and inheritance planning across jurisdictions.

Access to Education and Healthcare

Citizens enjoy local tuition fees and healthcare access in both countries.
In Malta, for instance, citizens benefit from free education and universal healthcare, including university-level studies.

Security and Family Continuity

Dual citizenship provides long-term mobility insurance — a secure alternative residence in times of political or economic uncertainty.
For globally mobile families, it supports succession, estate planning, and intergenerational stability.

Possible Shortcomings of Dual Citizenship

Taxation

Dual citizens may face tax obligations in both countries, requiring careful coordination of filings and relief under double tax treaties.
Countries like the U.S. tax their citizens on worldwide income, even when residing abroad, making specialist advice essential.

Legal Obligations and Military Service

Dual citizens remain bound by the laws and duties of each country, including possible military or civic service requirements.
Conflicts between jurisdictions must be managed through compliance and, where possible, bilateral exemptions.

Administrative Complexity

Holding two citizenships means managing multiple passports, tax IDs, and compliance obligations.
Understanding how to navigate each jurisdiction’s legal and regulatory framework is key to avoiding inadvertent breaches.
