10 countries that don’t allow Dual Citizenship

Dual citizenship allows a person to be legally recognised as a citizen of two countries at the same time. While many nations have embraced this concept to accommodate global mobility and migration, several countries still maintain strict laws that prohibit their citizens from holding another nationality.

In countries where dual citizenship is not allowed, individuals who acquire a second passport may be required to renounce their original citizenship or risk losing it automatically. Governments often justify these restrictions as a way to maintain national loyalty, simplify legal obligations, and avoid conflicts over taxation, military service, or political allegiance.

Below are 10 countries that generally do not allow dual citizenship.

10. Andorra

The small European principality of Andorra has one of the strictest citizenship policies in the world. Individuals who become citizens of another country may lose their Andorran nationality unless they renounce the foreign citizenship. Applicants seeking Andorran citizenship are typically required to live in the country for many years before qualifying.

9. China

China’s nationality law clearly states that the country does not recognise dual nationality. Chinese citizens who voluntarily acquire another nationality may automatically lose their Chinese citizenship under the law. (-)

8. India

India does not permit dual citizenship. Citizens who obtain another nationality are required to surrender their Indian passport. Instead of dual citizenship, India offers the Overseas Citizenship of India (OCI) programme, which grants certain residency and travel privileges but not full citizenship rights.

7. Japan

Japan generally requires citizens who acquire another nationality to renounce one of their citizenships. Individuals born with multiple nationalities must typically choose one nationality before reaching adulthood.

Singapore strictly prohibits dual citizenship. Citizens who voluntarily acquire another nationality are expected to renounce their Singaporean citizenship, as the country maintains strict laws to ensure loyalty and national identity.

Qatar is another country with strict citizenship regulations. Individuals who become citizens of another country generally lose their Qatari nationality unless they receive special approval from the government.
