How many citizenship can you hold in the United States?

USPublished 6 October 2026 · Written by BuyMeWhiskey Editorial Team · How we check facts

There is no single worldwide maximum number of citizenships. The United States permits its citizens to hold another nationality, and U.S. law does not require you to choose between U.S. and foreign citizenship. The practical limit is set by the laws of the countries involved.

There is no worldwide citizenship limit

Citizenship is a legal relationship with a particular country, so the idea of one global maximum does not really work. One country may allow multiple nationalities while another may require a person to give up an existing nationality when naturalising. A person can therefore hold several citizenships if the laws of all the countries involved permit the combination.

The U.S. Department of State specifically says a person can hold more than two nationalities. U.S. law does not require a U.S. citizen to choose between American citizenship and another nationality, and a U.S. citizen can normally naturalise in another country without automatically losing U.S. citizenship.

What can limit the number you hold?

The limiting factor is usually another country's nationality law. Some countries restrict dual citizenship, some allow it only for particular routes such as descent, and some make applicants renounce prior nationality when they naturalise. A person who wants three or four nationalities has to satisfy the rules for every new nationality while preserving the earlier ones.

There can also be practical obligations. A country may treat you as its citizen while you are physically there, regardless of which passport you used to enter. That can affect military service, tax reporting, registration, or access to consular assistance. The State Department warns that dual nationals can face conflicting obligations under the laws of the countries where they are nationals.

What about British citizens living abroad?

A British citizen does not normally lose British citizenship simply because they move overseas. The legal question is whether a person has performed an act that causes loss or renunciation of citizenship, rather than whether they live in Britain. A naturalised British citizen therefore needs to look at the specific route by which they became a citizen and the nationality law of the country where they intend to settle.

What if a Chinese citizen acquires another nationality?

China's nationality rules are different from U.S. rules and can be restrictive. A person should not assume that acquiring another passport leaves all previous rights untouched. Chinese nationality, household registration, travel documents and the treatment of dual nationality need to be checked with the Chinese authorities or a Chinese consulate before taking action.

Can a French parent give a child French citizenship?

Possibly. French nationality can be acquired by descent, but the detailed rules depend on the parent's French nationality, the child's circumstances and the evidence linking the generations. Having a French father is therefore a strong starting point, not an automatic answer in every case. The French consular service or the relevant French authority should confirm entitlement before an application is prepared.

Does U.S. green-card priority depend on birthplace or citizenship?

For many employment- and family-based immigrant visa categories, the country of chargeability is generally based on the applicant's country of birth rather than the passport they currently hold. That is why a second citizenship does not automatically move someone into a different visa queue. There are limited rules involving a spouse's or parent's place of birth, so the exact category matters.

Travel rules still matter

Being a multiple citizen can make travel easier in some circumstances, but it can also create obligations. U.S. citizens, including dual nationals, are required by U.S. law to enter and leave the United States using a U.S. passport. A second country can impose its own passport or entry requirements.

Check the rules before adding another citizenship

Check whether the new country permits multiple nationality.
Confirm whether naturalisation requires a renunciation.
Check how your existing countries treat voluntary acquisition of another nationality.
Understand passport, military-service and tax consequences before you travel.
Keep documentary evidence of every citizenship route and status.

Citizenship questions can become expensive when a person assumes that holding a passport and holding nationality are the same thing. They are not always the same. A passport is evidence of nationality and a travel document; the underlying legal status comes from the country's nationality law.

Apply the test separately to every nationality

For a person considering a third or fourth citizenship, the useful question is not a record number of passports but whether each legal system permits the combination. Start with the nationality you already hold, then test the proposed route: birth, descent, naturalisation or registration can each have different consequences. A passport issued by one country does not override another country’s citizenship law.

For travel, separate citizenship from entry paperwork. A U.S. citizen who also holds another nationality must use a U.S. passport to enter and leave the United States, while the other country may require its own passport. That can change which document you present at each border even though you remain the same person legally.

For anyone tracing citizenship through a parent, collect the parent’s nationality evidence and the civil records connecting parent and child. For someone applying through naturalisation, read the renunciation rule before filing. Those two checks prevent the common mistake of assuming that gaining a new nationality automatically has the same effect in every country.

Worked example

Illustrative example: Daniel is a U.S. citizen by birth and is also eligible for French nationality through a French parent. He is later considering another nationality through his spouse. The key question is not “how many passports may I have?” but whether each country allows him to keep the other nationalities.

U.S. law: Daniel can hold another nationality without being required by U.S. law to choose one.
France: he must confirm the French nationality-by-descent requirements and evidence.
Third country: he must check whether naturalisation requires renunciation of an existing nationality.

If all three legal systems permit the combination, he could hold three citizenships. If the third country requires him to give up one, the practical maximum would be two. There is therefore no calculation such as “three is the legal limit”; the answer depends on the intersection of the relevant nationality laws.

What is the maximum number of citizenships a person can have?#

There is no universal maximum. A person can hold more than two nationalities where the laws of all the relevant countries allow it. The real limitation is whether any country requires a person to renounce an existing nationality or treats voluntary acquisition of another nationality as affecting status.

Can a U.S. citizen have three citizenships?#

Yes, potentially. U.S. law does not require a U.S. citizen to choose between American citizenship and foreign nationality, and the State Department expressly recognises that people can hold more than two nationalities. The other countries involved must also permit the combination.

Can a British citizen live abroad without losing UK citizenship?#

Living abroad does not by itself cancel British citizenship. Loss of citizenship is a separate legal issue. The person should check the circumstances in which citizenship could be renounced or otherwise lost, particularly if another nationality is being acquired. For multiple nationality, compare the new country’s citizenship rule with the nationality you already hold before applying.

Does getting another passport make you lose U.S. citizenship?#

Not normally. The State Department says a U.S. citizen may naturalise in a foreign state without automatically losing U.S. citizenship. Loss of U.S. nationality requires a voluntary act together with the intention to relinquish U.S. nationality under the relevant law.

Can I get French citizenship because my father is French?#

You may have a nationality-by-descent route, but it depends on the parent’s status and the documentary chain proving the relationship and nationality. Do not rely on the passport alone: check the current French nationality procedure with the French consular authorities before filing.

Is a green card priority date based on citizenship or birthplace?#

For many immigrant visa categories, chargeability is based on the applicant’s country of birth rather than the citizenship shown on a passport. There are exceptions and special rules, so the relevant family or employment category needs to be checked before assuming that a second citizenship changes the queue.

Do dual citizens have to use a U.S. passport?#

Yes for U.S. entry and departure. The Department of State says U.S. citizens, including dual nationals, must enter and leave the United States using a U.S. passport. The other country may also impose its own passport requirement. For multiple nationality, compare the new country’s citizenship rule with the nationality you already hold before applying.
