Dual citizenship allows individuals to hold multiple nationalities and enjoy the benefits of each. However, some countries take a firm stance against dual citizenship, forcing individuals to choose one nationality over another. These nations, while offering a rich cultural and economic environment, have laws that could complicate your life and plans if you seek multiple allegiances. Let’s explore the top countries where dual citizenship is prohibited, and why it might not be in your best interest to even try.
China

China’s policy on dual citizenship is crystal clear: if you want to become a Chinese citizen, you must relinquish all other nationalities. The country’s government views dual citizenship as a threat to national loyalty and security, insisting that its citizens remain fully committed to the nation’s interests. For those with ties to China or seeking citizenship, this stringent requirement could mean an impossible choice between their past and their future.
India
India, with its vast and diverse population, adheres to the principle that a citizen’s allegiance should never be divided. The country mandates that anyone who acquires foreign citizenship must renounce their Indian nationality, including the right to vote. For those born in India who have ties to other countries, the Indian government offers an Overseas Citizen of India (OCI) card, but it’s no substitute for full citizenship.
Japan

Japan stands firm in its policy against dual citizenship. While individuals can hold dual nationality at birth, Japanese law requires them to choose one nationality by age 22. This policy ensures that citizens maintain clear allegiance to Japan and avoid any conflicts of interest. If you’re considering Japanese citizenship, be prepared to give up your previous nationality, as Japan will not allow both to coexist.
Saudi Arabia
In Saudi Arabia, dual citizenship is not permitted, and the country views it as a challenge to national unity. Foreigners can live and work in the kingdom, but acquiring Saudi citizenship while retaining another passport is not an option. In a country where loyalty and national identity are paramount, holding multiple citizenships can result in legal issues, with violators facing deportation.
Singapore

Singapore takes a hardline approach to dual citizenship, forbidding its citizens from holding another nationality. While you can become a Singaporean citizen, you’ll be required to renounce your original citizenship. For those with dual citizenship, Singapore’s laws are strict: acquiring another nationality results in automatic loss of Singaporean citizenship. This makes Singapore one of the most exclusive countries in terms of nationality laws.
United Arab Emirates
The UAE is another country where dual citizenship is prohibited. While foreign nationals can live in the UAE through work or residency programs, citizenship is reserved for those willing to forsake their original nationality. The UAE’s policy reflects its desire to maintain national loyalty and its broader cultural and political goals. Those hoping to gain UAE citizenship will have to choose between their past and future.
Thailand
Thailand’s laws are clear on dual citizenship: it’s simply not allowed. The Thai government insists that its citizens must commit fully to the country, without dividing their loyalty between two nations. Anyone wishing to acquire Thai citizenship must renounce their former nationality, and the law doesn’t offer exceptions. For many, this strict policy can become a barrier to establishing ties with Thailand, especially if they have deep connections elsewhere.
Norway

Norway has recently relaxed its stance on dual citizenship, but it still doesn’t allow people to hold more than one nationality. For those born with multiple citizenships, Norway requires individuals to choose between their Norwegian and a foreign passport. The country’s government has historically focused on national unity, and although recent changes have opened some possibilities, the concept of dual citizenship is still not fully embraced.
Austria
Austria’s strict rules on dual citizenship reflect its emphasis on national identity and loyalty. While it is possible to acquire Austrian citizenship, applicants must renounce any other nationality they hold. The country offers limited exceptions, such as for those who marry an Austrian citizen or certain high-skilled professionals, but in most cases, dual nationality is not an option.
Indonesia
Indonesia enforces strict policies against dual citizenship. The country’s government believes that it is essential for its citizens to fully commit to Indonesia and that holding multiple citizenships could undermine national unity. Indonesian law requires individuals to renounce any other nationality upon obtaining Indonesian citizenship. For those born with multiple citizenships, the country forces a decision, often by the time they reach 21.
Conclusion
For individuals seeking dual citizenship, these countries make it clear that loyalty cannot be divided. In countries like China, India, and Japan, laws prohibit nationals from holding multiple allegiances, and attempting to do so can have severe consequences. These policies reflect a deep cultural and political belief in the importance of undivided loyalty, national unity, and identity.
While the desire for dual citizenship may be tempting for those with international ties or ambitions, navigating the citizenship laws of these countries could create significant hurdles. If you’re eyeing citizenship in any of these nations, be prepared to make tough choices regarding your allegiance, as these countries are firm in their stance against dual nationality.
