Which Countries Make You Give Up Your Citizenship for a Second Passport? (2026)

Securing a second passport has become an ultimate Plan B for most global investors today. It appears as a fresh breeze during times of uncertainty or political instability. There are certain countries that restrict second citizenship and their nationals need to give up their current citizenship for securing another passport.

However, the consequences vary for countries. Some countries’ citizens automatically lose their current citizenship while others countries require formal renunciation or nationality selection from their citizens. Hence, global investors interested in a second passport through citizenship by investment programs should first understand the rules and regulations of both countries. 

As per the latest citizenship by investment reports, the demand for second passports is increasing day by day among investors seeking greater global mobility, business opportunities, and family security. Still, understanding of nationality restrictions remains very crucial especially for individuals of countries that do not allow dual citizenship in 2026.  

Can You Lose Your Original Citizenship After Getting a Second Passport?

Yes, because some countries restrict dual nationality and require their citizens to give up on their current nationality in order to secure another citizenship. Rules and policies keep changing from time to time so global investors must stay updated and understand the nationality restrictions of countries before choosing a second citizenship program.  

Which Countries Do Not Allow or Restrict Dual Citizenship in 2026?

Numerous countries restrict their citizens from securing multiple citizenships. However these restrictions differentiate based on how their citizens secure second citizenship. The following table will help you understand that as well as the potential consequences associated with it. 

Countries Where Second Citizenship Can Affect Your Original Nationality

China: Foreign Citizenship Can Lead to Loss of Chinese Nationality

China does not allow dual citizenship. As per the Article 9 of Nationality Law of People’s Republic of China, a Chinese citizen who secures foreign citizenship will automatically lose the Chinese citizenship. 

The decision won’t require any formal notifications or a day, the individual will lose Chinese nationality the same day another citizenship is acquired. The consequences will be immediate, your rights including education, property pension, and border-crossing for your whole family may also change from that moment. 

This is why securing a second passport is a very important legal decision for Chinese investors who are considering citizenship by investment. 

India: Acquiring Foreign Nationality Means Losing Indian Citizenship

India does not allow its citizens to maintain Indian citizenship after securing a foreign citizenship. They cannot become dual nationals while still remaining the citizens of India. 

Under the Section 9 of Citizenship Act, 1955, India automatically terminates an individual’s Indian citizenship if they voluntarily secure citizenship of another country. 

The Indian passport becomes invalid at that moment. The decision does not even require a formal cancellation order from the government. Therefore, it is crucial for Indian investors to understand the rules to make an informed decision. 

Singapore: Adult Citizens Cannot Retain Multiple Nationalities

Singapore does not allow its adult citizens to become dual nationals or secure multiple citizenships. According to the Singapore Ministry of Home Affairs, adult citizens who have secured multiple citizenships must give up their foreign citizenship if they want to remain a Singaporean citizen. 

Failure to renounce foreign citizenship will end up in deprivation of Singaporean citizenship. Between the years 2019 and 2023, around 1600 adult Singaporean citizens annually, on average renounced or were deprived of Singaporean citizenship because they held multiple citizenships. 

This shows that nationality restrictions can have real consequences beyond just the passport eligibility. 

Japan: Citizens May Have to Choose One Nationality

Under the Nationality Act of Japan, the individuals holding multiple citizenships must select a nationality within the applicable legal deadline. The Japanese citizens who voluntarily secure a foreign citizenship may lose Japanese citizenship under separate provisions. 

Hence, if the Japanese investors want to secure a second passport then they should understand the nationalities rules first to avoid facing consequences later. They should seek guidance regarding nationality rules and procedures. 

Nepal: Foreign Naturalisation Can Terminate Nepali Citizenship

Under Section 10 of Nepal’s Citizenship Act, the Nepali citizenship is automatically terminated when an individual secures any foreign citizenship. 

The individual loses citizenship at that exact moment. Therefore, Nepali investors must seek professional guidance if they seek ways to possess multiple nationalities. 

What Can Investors of these Countries Consider Instead?

Residency by Investment Pathways

Residency by investment programs are better alternatives to dual citizenship for individuals from countries that make you give up citizenship. The programs may allow eligible investors to secure residence rights in another country without needing them to acquire foreign citizenship.

They appear as a smart Plan B for those who seek international relocation, family residence, and business expansion opportunities. However, residency differs from citizenship so it does not automatically provide unrestricted international travel. 

Second Citizenship with an Informed Renunciation Decision

Some investors may still decide that securing a second citizenship is better for them then they must first understand the nationality laws before proceeding. A professional immigration guidance can help the investors get a strong second passport aligning with their long-term goals and objectives. 

Dominica, Grenada and St Kitts and Nevis second passports provide visa-free and visa-on-arrival access to around 140 or more destinations. Moreover, the programs also allow family inclusion which means you can live with your loved ones. 

Why Is Professional Immigration Advice Important?

Global investors must not only select citizenship by investment program randomly or by seeing a list of best programs. Rather, they should choose the program that best suits their profile and aligns with their goals and objectives.
