Countries That Allow Dual Citizenship
Key findings
- Most countries permit dual or multiple citizenship in some form.
- Dual citizenship isn't just a yes or no matter. Countries usually fall into one of two practical camps: broad recognition or limited recognition.
- Several countries permit dual citizenship only for citizens by birth, descent, restoration, treaty, special permission, or a narrow statutory category.
Dual citizenship is increasingly common. For some, the bigger question isn't whether dual citizenship is an option, but whether a specific pathway lets them keep the citizenship they already have.
This report is the companion to countries that do not allow dual citizenship. It is a country-level index of places where dual or multiple citizenship is broadly permitted, plus places where it is permitted only in important but limited categories. Due to the complexities of immigration law and bilateral relations, this report does not attempt to identify the potential compatibility of every naturalization, descent, marriage, restoration, or investment route.

What "allows dual citizenship" means here
This report uses three categories.
| Category | Meaning | How to use it |
|---|---|---|
| Broad recognition | The country generally allows its citizens to hold another citizenship, and ordinary acquisition routes usually do not require renunciation. | These are the easiest countries to treat as dual-citizenship-friendly. |
| Limited recognition | Dual citizenship is allowed, but only for certain acquisition modes, origin countries, permission grants, restoration categories, or treaty groups. | Check the exact pathway before relying on the country as dual-friendly. |
| Internal disregard | The country may allow or tolerate multiple citizenship, but may ignore the second citizenship while the person is inside the country. | Passport, consular assistance, military, tax, and public-office rules still matter. |

Countries with limited recognition of dual citizenship
These countries allow dual citizenship, but they often have route-specific limitations. A person may be able to hold dual citizenship by birth, descent, restoration, treaty, government approval, or a special category while ordinary naturalization still requires renunciation.
| Country | What to check |
|---|---|
| Afghanistan | Dual nationality has been recognized in the post-2001 framework, but current governing law and practice require fresh local confirmation. |
| Algeria | The law no longer has a general renunciation condition for naturalization, but dual status can still affect political roles and may create revocation or recognition issues. |
| Austria | Dual citizenship can exist by birth, prior retention permission, inability to renounce, hardship exceptions, or restitution categories, but ordinary voluntary naturalization remains strict. |
| Bahamas | Dual citizenship can be possible for some citizenship-by-birth or automatic-descent situations, but registration and naturalization routes can require renunciation. |
| Bangladesh | Dual nationality certificates may be available for citizens of many countries, but the rule is not universal. |
| Bosnia and Herzegovina | Dual citizenship is generally treaty-dependent or otherwise limited. |
| Bulgaria | Bulgarian citizens by origin can often keep another citizenship, while ordinary naturalization may involve a renunciation requirement. |
| Central African Republic | Dual nationality is generally restricted, but a narrow marriage-based category can preserve a foreign nationality. |
| Croatia | Emigrant, diaspora, and origin-based routes are often dual-friendly; ordinary naturalization can be different. |
| Egypt | Dual citizenship may be permitted with approval, but it can affect political and public-office rights. |
| El Salvador | Citizens by birth may hold dual nationality; ordinary naturalization can include a renunciation clause. |
| Estonia | Citizens by birth have stronger protection, but naturalized citizenship and voluntary acquisition of another nationality need careful review. |
| Georgia | Dual citizenship is possible by presidential exception, including for some people of Georgian descent, but it is not automatic. |
| Kiribati | People of I-Kiribati descent may be dual nationals, but naturalized citizens without that heritage can face a renunciation requirement. |
| Latvia | Dual citizenship is allowed for specific country groups and origin categories, including many EU, NATO, EFTA, Australian, Brazilian, and New Zealand cases. |
| Lithuania | Dual citizenship is limited to specific statutory categories, including some exile-descendant and restoration cases. |
| Marshall Islands | Dual nationality can exist, but the registration category, acquisition route, and denaturalization exceptions should be checked before relying on it. |
| Monaco | Dual nationality is possible in some special cases, especially certain marriage-based situations, but ordinary naturalization generally requires renunciation. |
| Montenegro | Dual citizenship may be possible in limited treaty, regional, or government-approved cases. |
| Namibia | Citizens by origin have stronger protection against deprivation, while naturalized citizens face stricter dual-nationality limits. |
| Netherlands | Dual citizenship is possible through exceptions such as birth, marriage to a Dutch citizen, option procedure, or inability to renounce; ordinary naturalization remains a renunciation trap. |
| Pakistan | Dual nationality is allowed with specified countries and agreements, not universally. |
| Panama | Citizenship by birth or descent can be dual-compatible, while naturalization has a renunciation issue in practice. |
| Papua New Guinea | Multiple nationality is allowed only with specified countries and requires registration. |
| Philippines | Dual citizenship is especially important for natural-born Filipinos and reacquisition under RA 9225; first-time naturalization can require renunciation. |
| Slovakia | Dual citizenship may be preserved in several categories, but voluntary acquisition of another citizenship has historically created loss risks unless an exception applies. |
| Slovenia | Dual citizenship is possible in some origin and special-interest cases, but naturalization can require release from prior citizenship. |
| South Korea | Multiple nationality is possible for some groups, often with a pledge not to exercise the other nationality in Korea; ordinary naturalization and nationality-choice rules need review. |
| Spain | Dual nationality is permitted with specific countries and categories, including many Ibero-American, Andorran, Portuguese, Filipino, and Equatorial Guinean cases. Most other ordinary naturalization applicants are expected to renounce prior nationality. |
| Sri Lanka | Dual citizenship can be granted through an approval process. |
| Taiwan | Taiwanese nationality by birth can coexist with another nationality, but ordinary naturalization usually requires proof of loss or renunciation of the prior nationality unless a special exception applies. |
| Togo | Dual nationality is restricted in law, but some narrow categories, including certain marriage-related cases, can exist in practice. |
| United Arab Emirates | Dual citizenship is possible for selected categories and government-approved cases, but not as a general entitlement. |
| Vatican City | Vatican citizenship is office-, function-, or residence-based and can coexist with another nationality, but it is not an ordinary public immigration pathway. |
| Vietnam | Some overseas Vietnamese, special-contribution, spouse, parent, child, or exception cases may keep another citizenship, but ordinary naturalization is usually single-citizenship oriented. |
Citizenship-by-investment countries
Most current citizenship-by-investment programs are dual citizenship friendly. For applicants who want a second passport without giving up an existing citizenship, this is one reason Caribbean programs remain prominent.

Countries that allow dual citizenship but may ignore it internally
Dual-friendly countries often apply a "local citizen first" rule inside their own borders: they treat you as their citizen, ignoring any other citizenship you might hold. Practically, this means a dual citizen may need to enter and leave on that country's passport, may not receive foreign consular protection while there, and may still owe military, tax, registration, or voting duties.
| Country | Practical context | What to check |
|---|---|---|
| Argentina | Argentine citizenship is broadly dual-friendly, but Argentina may still treat a dual citizen as Argentine while they are in the country. | Passport-use rules and whether foreign consular protection is limited while in Argentina. |
| Brazil | Brazilian citizenship can be very useful for mobility and family ties, but citizens abroad may still have routine administrative duties. | Passport-use rules, voting regularity, and military-status paperwork for male citizens. |
| Colombia | Colombia generally permits dual citizenship, but local authorities may focus on the Colombian status when a dual citizen is in Colombia. | Passport-use rules and whether foreign consular protection is limited while in Colombia. |
| Cuba | Cuban nationality can involve more country-specific travel and documentation rules than many other dual-friendly systems. | Passport-use rules, entry and exit rules, and any special duties for Cuban citizens abroad. |
| France | France is broadly dual-friendly; the main point is that a French citizen in France is usually treated as French first. | Passport-use expectations, public-office limits, and any civic duties that may apply. |
| Greece | Greece permits dual citizenship, and many claims are ancestry-based, but military-status questions can matter for some male citizens. | Passport-use rules and military-status issues for male Greek citizens, including citizens by descent. |
| Israel | Israel is broadly dual-friendly, especially for many Law of Return cases, but citizens may still need to think about local status and service rules. | Passport-use rules, military-status questions, and limits on foreign consular protection while in Israel. |
| Mexico | Mexico permits dual nationality, and many dual citizens use it without major friction, but Mexico may treat them as Mexican while in Mexico. | Passport-use rules and whether Mexican authorities treat the person only as Mexican while in Mexico. |
| Poland | Poland permits dual citizenship, but Polish authorities generally treat Polish citizens as Polish while they are dealing with Polish law or documents. | Passport-use rules, civil-registration duties, public-office limits, and any military-status questions. |
| Russia | Russia permits multiple citizenship in some circumstances, but it has more formal reporting and security-sensitive rules than many dual-friendly countries. | Passport-use rules, registration duties, and any reporting or security-related restrictions. |
| Turkey | Turkey is broadly dual-friendly, and many dual citizens manage status through consular processes when abroad. | Passport-use rules and military-status questions for male Turkish citizens. |
| United States | The United States permits dual citizenship, but U.S. citizenship remains active even when another citizenship is added. | U.S. passport-use rules, tax and financial-reporting duties, and limits on foreign consular protection while in the United States. |
Practical takeaways
- Treat broad recognition countries as the easiest dual-citizenship planning group.
- Treat limited recognition countries as a possibility, requiring additional investigation.
- Do not assume descent, marriage, restoration, investment, and ordinary naturalization are all treated equally, for dual citizenship purposes.
- Double-check a country's renunciation rules before naturalizing.
- If you already have multiple citizenships, check passport-use, military, tax, and public-office rules in each country.
