How Many Citizenships Can You Have? 2026 Guide

The answer to, “how many citizenships can you have?” is that there is no official limit. You can have as many citizenships as you can get access to, provided each country permits multiple citizenship.  

Over 120 countries allow multiple citizenship, including nations like the US and the UK. Countries like Japan and India do not allow dual citizenship at all and require renunciation in the case of acquiring another citizenship.  

Our guide explains the laws and regulations surrounding multiple citizenship, how to acquire additional citizenship, the benefits of multiple citizenship, and more.  

How Many Citizenships Can You Have: Key Takeaways

There is no legal limit to the number of citizenships you can possess, providing the countries involved allow dual or multiple citizenship. 

More than 120 countries allow at least dual citizenship, and this includes Canada, the US, and the UK.  

Some countries like China, India, and Japan do not allow dual citizenship at all.  

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

Obtaining foreign citizenship can be done through descent, naturalization, marriage, and 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 has become 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. 

The answer will depend on your personal goals. Some individuals are happy with only a single powerful passport, while others prefer a diversified passport portfolio. Having multiple passports allows you to maximize travel freedom, tax efficiency, and security.  

Consider the following when acquiring multiple citizenship: 

• Weigh the Pros and Cons: If you are considering acquiring another passport, you should be aware of the advantages, like expanded travel access, and the disadvantages, like administrative requirements.  
• Have a Clear Strategy: Decide what your motivation is behind acquiring additional passports. This could be for expanded visa-free travel, relocation, plan B, tax advantages, or business opportunities.  
• Decide How Many Passports are Enough: Most people find that two or three passports are sufficient. A primary or original passport, a business/tax passport, and a lifestyle/home passport. 
• Diversify Your Passport Portfolio: This means expanding the number of passports you have so that you are able to access the advantages that each of them offer. Adding a new passport to your portfolio will strengthen your international options and your travel flexibility.  

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: 

01/ 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.  

For example, a child is born in Los Angeles to parents with the same foreign nationality. This child would acquire US citizenship at birth, and, if the family returns to their country and the child qualifies, the child would have dual citizenship by birth.   

02/ 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 and some even allow claiming citizenship if your grandparent was a citizen. Portugal allows those with at least one Portuguese grandparent to register for Portugal citizenship by descent. 

03/ 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 five years of legal residence and this is one of the shortest timelines in Europe. This can be obtained through visas such as the Portugal D7 Visa and the Portugal Golden Visa. 
• Germany requires eight years which can be reduced to seven with integration courses. 
• Canada requires three years of legal residence within a five-year period.  

04/ 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 and legal residence. France allows citizenship after three years of marriage, even if the couple does not live in the country.  

05/ Citizenship by investment

Citizenship by investment or CBI is the practice of investing in a country and acquiring immediate citizenship as a result. The usual options for investment include real estate, business, bank deposits, and more.  

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 visa-free access to 167 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 or visa-on-arrival access to 56 countries. If they acquire a Spanish passport, that number increases to 127 countries. 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 also confers the right to work and do  business in a foreign country. This will expand your business horizons to new markets and new continents. An additional citizenship is particularly useful for entrepreneurs looking to access new markets for their business.  
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 a 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 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 10 years, which means a minor degree of administration will always be involved. 

The countries that allow dual citizenship and multiple citizenship includes the following, but this is not an exhaustive list:
