How Many Citizenships Can You Have in 2026

You can have as many citizenships as you can legally acquire and retain, provided each country permits multiple citizenship. There is no single global maximum, and the practical limit depends on every relevant country’s law.    

Many countries, including the US, Canada, and the UK, permit multiple citizenship. Others prohibit it, do not recognize it domestically, or allow it only in specified circumstances.  

For example, India does not permit full dual citizenship, and Japan does not allow dual citizenship and requires those with more than one nationality to choose one by a set deadline and make efforts to renounce the other nationality, according to the Japanese Nationality Act.

How Many Citizenships Can You Have: Key Takeaways

There is no universal legal limit to the number of citizenships you can have, but every country involved must allow you to acquire and retain citizenship.  

Many countries allow at least dual citizenship, including Canada, the US, and the UK.   

Some countries, such as China, India, and Japan, may restrict or not allow dual citizenship at all. India does not permit full dual citizenship, China does not recognize it, and Japan requires multiple nationals to choose a nationality.  

Getting a second or third passport should be done with a clear strategy and can provide benefits like drastically expanded visa-free travel.   

Foreign citizenship can be obtained through descent, naturalization, marriage, or investment.  

There is no legal limit on the number of citizenships that you can have. Many countries permit dual citizenship, triple citizenship, and multiple citizenship. However, some countries do not permit dual citizenship at all and will require renunciation in the case of acquiring additional citizenship.   

According to our Global Intelligence Unit’s The Transformation of Citizenship report, holding dual or multiple citizenship can be a powerful Plan B, offering protection and flexibility in an uncertain political environment. It helps individuals diversify their assets, hedge against local risk, and secure access to stable economies and healthcare systems.  

Whether you should have more than one citizenship depends on your goals and the legal and financial obligations involved. An additional citizenship may provide residence, work, family, or travel rights, but it can also create tax reporting, passport-use, military-service, and consular limitations. 

Consider the following when acquiring multiple citizenship:  

• Your goals: Do you want greater travel freedom, the right to live or work elsewhere, family reunification, business opportunities, or a secure relocation option?  
• Citizenship laws: You must confirm that each country involved allows you to acquire and retain the other citizenship. This is because some countries require renunciation or restrict multiple citizenship in certain circumstances. 
• Tax and reporting obligations: Citizenship does not automatically reduce your taxes. Tax liability usually depends on residence, income sources, and local law, although some countries impose filing or reporting obligations on citizens living abroad. 
• Travel and passport rules: Check which passport you must use when entering or leaving each country of citizenship. You should also consider renewal costs, visa-access overlap, and whether another passport provides meaningful additional mobility. 
• Other legal obligations: Multiple citizens may face military service requirements, restrictions on certain public positions, or limited consular assistance while visiting another country of citizenship. 

An additional citizenship is most valuable when it provides rights or protections that you will realistically use without creating disproportionate obligations. 

There are several ways of acquiring multiple citizenship, and the options available to you will depend on your family’s heritage and your resources. The following are the most common ways of acquiring citizenship:  

1. Citizenship by birth 

Citizenship by birth, or Jus Soli, applies in certain cases, even if both parents are of a foreign nationality. Countries with birthright citizenship like the United States, Canada, and Brazil grant citizenship to anyone born in the country. These laws allow a practice known as birth tourism.  Exceptions apply, including certain children of accredited foreign diplomats. 

For example, a child born in Los Angeles generally acquires US citizenship at birth. If a parent’s country also transmits citizenship by descent, the child may hold both citizenships from birth. 

2. Citizenship by descent 

Citizenship by descent, or Jus Sanguinis, allows you to claim citizenship through your ancestry. Countries like Italy, Ireland, Poland, and Hungary all allow this practice with associated restrictions. For example, Portugal citizenship by descent allows the qualifying grandchildren of an original Portuguese citizen who did not lose Portuguese nationality to apply, subject to the applicable connection, language, and eligibility requirements.  

3. Citizenship by naturalization 

Citizenship by naturalization is the practice of acquiring citizenship after a period of living in the country. The requirements will vary by nation and often include a form of language and/or culture test.   

Portugal offers naturalization after ten years of legal residence under the revised Nationality Law (Organic Law No. 1/2026). This timeline is reduced to seven years for nationals of Portuguese-speaking countries and EU member states. Portugal citizenship by naturalization can be obtained through visas such as the Portugal D7 Visa and the Portugal Golden Visa.  

Germany requires five years of legal residence to be eligible for naturalization. Canada requires permanent-resident status and at least 1,095 days of physical presence during the five years before applying.  

4. Citizenship by marriage 

Citizenship by marriage allows foreign spouses to acquire citizenship on a fast track. In most nations, the timeline to naturalization is greatly reduced for a foreign spouse living in the country.   

For example, Spain allows foreign spouses to apply for Spanish citizenship after only one year of marriage to a Spanish national and legal residence. France allows citizenship after four years of marriage, rising to five years in certain cases involving residence abroad or insufficient French consular registration. 

5. Citizenship by investment 

Citizenship by investment provides a direct route through which qualifying applicants make an approved contribution or investment and undergo government due diligence before citizenship may be granted.  

Some popular options include the Vanuatu Citizenship by Investment program, the fastest in the world, with processing times between one and two months. The St Kitts and Nevis Citizenship by Investment program is the oldest of its kind, with a starting cost of $250,000, and access to over 160 countries, including the UK and the Schengen Area.  

1. Expanded visa-free travel: Acquiring a second passport can expand your visa-free and visa-on-arrival travel drastically. For example, as of 2026, an Indian citizen has visa-free, ETA, or visa-on-arrival access to 106 countries. If they acquire a Spanish passport, that number increases to 184 countries and would have to give up his Indian citizenship. To help people find the best country for a second citizenship, our Global Intelligence Unit developed the Global Passport Index, which ranks the world’s most powerful passports  
2. Tax advantages: Becoming a citizen of a country with a favorable tax environment allows you to legally reduce your tax burden. The Cayman Islands, for example, do not tax personal income, which is greatly beneficial for high-net-worth individuals.  
3. Business opportunities: Citizenship normally provides an unrestricted right to live and work in the issuing country. Some citizenships, such as those of EU member states, may provide wider regional mobility and employment rights.   
4. Familial connections: People with ancestral citizenship can access a foreign country, and many others, by acquiring that country’s passport. This boosts the ability to spend time with family thanks to the removal of travel restrictions.  
5. Political stability: In times of political uncertainty or turmoil, having multiple citizenships enables access to a more stable and safer nation.   
6. Lifestyle options: A second citizenship allows holders to upgrade their quality of life. They can move to countries with universal healthcare for residents, year-round pleasant weather, and high safety standards, such as Portugal and Spain. 

1. Reporting requirements: Some countries, like the US, require their citizens to file an annual tax return regardless of their country of residence. These obligations can be mitigated through tax treaties, credits, and exclusions that help to reduce or avoid double taxation.   
2. Bureaucracy: Managing multiple citizenships can incur some bureaucratic admin that must be handled. Applying for citizenship can be a difficult process, which is why it is recommended to consult experts, like Global Citizen Solutions.   
3. Ineligibility for government positions: Some countries do not allow dual citizens to hold positions in government, military, or law enforcement. This means that those pursuing multiple citizenship should ensure that they are not prohibited, if these careers are something that they desire.   
4. Passport administration: Nations tend to require citizens to enter and exit the country on that country’s passport. Additionally, passports need to be renewed every few years, which means a minor degree of administration will always be involved.  

The following countries allow dual citizenships or more.  “Automatic” refers to multiple citizenship arising without a separate naturalization decision, most commonly at birth. “Acquired” refers to obtaining another citizenship later through naturalization, marriage, or another voluntary process.
