Nauru permits dual citizenship under its current legal system, mainly governed by the Nauru Citizenship Act 2017 and the Constitution of Nauru. These legal instruments clearly define the Nauru dual citizenship rules, including how one can acquire, retain, or lose citizenship, and how multiple nationalities are treated under Nauruan law.

Legal Framework and Nauru Dual Citizenship Rules:

The Nauru Citizenship Act 2017 repealed the previous 2005 Act and introduced a more comprehensive structure for citizenship in Nauru. The following are its main provisions:

• Citizenship by Birth: Individuals born in Nauru to at least one Nauruan parent automatically receive citizenship. Children born in Nauru who would otherwise be stateless can also obtain it.
• Citizenship by Descent: Individuals born abroad to Nauruan parents may acquire citizenship if at least one grandparent holds Nauruan citizenship.
• Naturalization: Foreign nationals married to Nauruan citizens may apply for naturalization after seven years of legal residency, assuming good character and knowledge of Nauruan customs.
• Adoption: Children legally adopted by Nauruan citizens are eligible for citizenship.

The Nauru dual citizenship rules are central to this framework. They enable individuals to acquire Nauruan nationality while keeping their original citizenship, with no automatic loss of either.

Dual Citizenship Rights and Obligations: 

Nauru explicitly recognizes and supports dual citizenship. Under Nauru dual citizenship rules, people are allowed to retain other nationalities without risking their Nauruan citizenship. However, a few conditions and responsibilities still apply:

• Voluntary Renunciation: Citizens can voluntarily renounce their Nauruan citizenship upon acquiring another nationality.
• Revocation: Citizenship may be revoked if obtained through fraud, misrepresentation, or concealment of essential facts.
• Political Participation: Judicial rulings in Nauru have found any restriction on dual citizens running for parliament unconstitutional. This ensures the rights of dual nationals to engage in political life.

Nauru’s Climate Resilience Citizenship Program (NECRCP): 

In 2024, Nauru introduced the Nauru Economic and Climate Resilience Citizenship Program (NECRCP), a citizenship-by-investment initiative authorized under the Nauru Economic and Climate Resilience Citizenship Act 2024. This initiative reflects Nauru dual citizenship rules by allowing investors to retain their original nationality.

This program is designed to attract visionary investors who are eager to support Nauru’s journey toward environmental sustainability and climate resilience.

Key Features:

• Investment Requirement: Applicants must contribute to Nauru’s Treasury Fund, which is directed toward critical climate adaptation projects.
• Processing Time: Application reviews generally take between three and four months, depending on documentation and due diligence procedures.
• Eligibility: Applicants must be at least 18, have a clean legal record, and prove the legal source of their funds.
• Unrestricted Dual Citizenship: Nauru does not impose residency or visitation requirements and fully supports Nauru dual citizenship rules.
• Family Inclusion: The application may include spouses, parents, siblings, and other dependents.

By joining the NECRCP, investors gain not only a second citizenship but also an opportunity to contribute meaningfully to the planet’s future, without sacrificing their existing nationality under Nauru’s progressive dual citizenship rules
