Nauru Citizenship by Investment Eligibility Requirements 2026: Who Qualifies?

Last updated: March 2026

Nauru's Economic and Climate Resilience Citizenship Program (NECRCP) has emerged as one of the most affordable and family-friendly citizenship by investment options available in 2026. With a contribution starting from USD 90,000 under a limited-time promotional offer, applicants aged 18 and above with a clean criminal record can obtain Nauruan citizenship in as little as three to five months. Crucially, Nauru offers one of the most generous family eligibility policies in the CBI industry: there are no age limits for dependent children or parents, siblings can be included, and there is no financial dependency requirement for qualifying relatives.

This eligibility guide from Mirabello Consultancy explains exactly who qualifies for Nauru CBI, what the family inclusion rules are, how due diligence works, and what documentation you need to prepare. For a broader comparison of affordable citizenship options, see our guide to the best citizenship by investment programmes.

What Is the Nauru Citizenship by Investment Programme?

The Nauru Economic and Climate Resilience Citizenship Program is a government-authorised pathway that grants full Nauruan citizenship and a passport to qualifying foreign nationals who make a non-refundable contribution to the Nauru Economic and Climate Resilience Fund. Enacted through the Economic and Climate Resilience Citizenship Act No. 15 of 2024, the programme was formally unveiled at COP 29 in Baku, Azerbaijan, in November 2024.

The programme is administered by the Nauru Program Office (NPO), which is managed by Henley & Partners under a government mandate. Final approval authority rests with the Cabinet of the Republic of Nauru. Funds raised through the programme are directed toward climate resilience initiatives, renewable energy infrastructure, and economic diversification away from Nauru's historic phosphate dependency.

Unlike Caribbean CBI programmes that offer multiple investment routes (donation, real estate, enterprise), Nauru operates a single contribution-based model. This streamlined approach simplifies eligibility assessment and accelerates processing times.

Who Is Eligible for Nauru Citizenship by Investment?

To qualify for Nauru CBI, applicants must meet a set of clearly defined eligibility criteria established under the ECRC Act. The programme is open to most nationalities, subject to due diligence screening and government approval.

One of the programme's most distinctive features is the mandatory interview requirement. Every principal applicant must attend an interview conducted by an independent due diligence firm commissioned by the Nauru Program Office. This is an additional layer of screening not found in most Caribbean CBI programmes and reflects the NPO's emphasis on programme integrity.

What Are the Age Requirements for Nauru CBI?

The principal applicant must be at least 18 years of age at the time of application. There is no upper age limit for principal applicants, making the programme accessible to investors at any stage of life.

For dependent family members, Nauru's eligibility rules are notably more generous than most competing programmes. There are no age limits for dependent children or parents. This means adult children of any age — including those who are married — can be included in a family application. Similarly, parents of the principal applicant or their spouse can be added regardless of their age, with no financial dependency requirement.

This stands in contrast to Caribbean CBI programmes, where dependent children are typically capped at age 30 and parents must usually be aged 55 or older and financially dependent on the applicant.

Can Family Members Be Included in a Nauru CBI Application?

Yes, and Nauru offers one of the most expansive family inclusion policies in the global CBI market. The programme's 2025–2026 updates removed previous age limits and financial dependency requirements, creating a uniquely inclusive framework for family applications.

The flat contribution structure is another major advantage for families. Whether you apply as an individual or include your entire family, the core contribution remains the same at USD 115,000 (or USD 90,000 under the promotional rate valid until 30 June 2026). Additional dependents incur only application and due diligence fees — not a second full contribution. This makes Nauru one of the most cost-effective family CBI options globally.

What Are the Due Diligence Requirements?

Nauru's due diligence process is comprehensive and multi-layered, reflecting the programme's commitment to integrity and international compliance standards. The process involves three distinct bodies:

• Nauru Program Office (NPO) compliance officers — conduct initial screening and application review
• Nauru Police Force — perform criminal background checks through Interpol and national databases
• Independent international due diligence firms — commissioned by the NPO to conduct enhanced background investigations

Key elements of the due diligence screening include:

• Criminal history verification across all countries of residence
• International sanctions and watchlist screening (UN, EU, OFAC, and other lists)
• Source of funds and source of wealth verification
• Politically Exposed Person (PEP) status assessment
• Adverse media screening
• Mandatory in-person interview with the principal applicant

The mandatory interview is a distinctive feature of the Nauru programme. Every principal applicant must sit for an interview conducted by a due diligence firm commissioned by the NPO. This interview assesses the applicant's motivations, background, and the legitimacy of their investment funds. While most CBI programmes rely solely on documentary evidence, Nauru's interview requirement adds an additional verification layer.

What Police Certificates and Documents Are Required?

Applicants must provide police clearance certificates from every country in which they have resided for six months or more during the preceding ten years. This is a broader requirement than many CBI programmes, which typically request certificates only from the applicant's country of citizenship and current country of residence.

Additional documentation requirements include:

• Valid passport with minimum six months' validity and certified copies
• Birth certificate (original or certified copy)
• Marriage certificate (if including spouse)
• Birth certificates for all dependent family members
• Comprehensive proof of source of funds (bank statements, business records, investment portfolios, tax returns)
• Professional CV or résumé detailing employment and business history
• Passport-size photographs meeting specified standards
• Completed application forms for principal applicant and each dependent
• Medical examination results demonstrating good health

All documents must be certified, notarised, and translated into English where applicable. The NPO may request additional documentation during the review process.

What Are the Health Requirements for Nauru CBI?

Good health status is a mandatory requirement for all applicants and dependents. The programme requires applicants to demonstrate they are in good health, though the specific medical examinations and tests required have not been publicly disclosed in full detail [VERIFY: exact medical examination requirements]. Applicants should expect to provide a general medical certificate at minimum, and the NPO may request additional health screening based on individual circumstances.

Health requirements apply to all applicants in the family application, including the principal applicant, spouse, children, parents, and siblings. Medical certificates should be issued by licensed medical practitioners and be current at the time of application submission.

How Does Source of Funds Verification Work?

All applicants must demonstrate that their investment funds are derived from legitimate sources. The source of funds verification is a critical element of the due diligence process and typically requires documentation showing:

• Employment income — salary statements, employment contracts, tax returns
• Business ownership — company registration documents, audited financial statements, dividend records
• Investment returns — portfolio statements, capital gains documentation
• Inheritance — probate documents, inheritance tax records
• Property sales — sale agreements, title transfers, settlement statements
• Gifts — gift declarations with supporting documentation of the donor's source of funds

The NPO's compliance team works alongside independent international due diligence firms to verify the legitimacy and trail of funds. This multi-layered approach ensures compliance with international anti-money laundering (AML) and counter-terrorism financing (CTF) standards.

Are There Any Excluded Nationalities?

The Nauru CBI programme does not publicly list specific excluded nationalities [VERIFY: full list of excluded nationalities, if formally defined]. However, as with all CBI programmes, applicants from countries subject to international sanctions (including UN Security Council sanctions and OFAC Specially Designated Nationals lists) are likely to face restrictions or automatic disqualification.

Applicants from higher-risk jurisdictions may face enhanced due diligence requirements and longer processing times, but are not necessarily excluded. The Cabinet of the Republic of Nauru retains ultimate discretion over all citizenship approvals, and applications are assessed on a case-by-case basis.

How Does Nauru’s Eligibility Compare to Other CBI Programmes?

Nauru's eligibility framework stands out in several key areas when compared to Caribbean and other Pacific CBI alternatives. The expanded family inclusion policy is particularly noteworthy.

Most Dominica and St. Lucia CBI applications cap dependent children at age 30 (or 31 in some cases) and require parents to be aged 55 or older with proven financial dependency. Antigua & Barbuda offers somewhat broader family inclusion but still imposes age-based restrictions. Nauru eliminates these limitations entirely.

Additionally, the flat contribution model — where the core contribution remains the same regardless of family size — creates significant cost savings for larger families compared to Caribbean programmes, where additional dependents can add USD 25,000–50,000 each to the total cost.

The mandatory interview requirement is unique to Nauru among current CBI programmes and may be viewed as either a strength (demonstrating programme integrity) or a consideration (requiring additional preparation). For a comprehensive comparison, see our guide to the cheapest citizenship by investment programmes in 2026.

What Happens After Approval?

Once an application is approved by the Cabinet, the principal applicant makes the required contribution payment. Upon confirmation of payment, the NPO issues a Certificate of Citizenship followed by the Nauruan passport. The entire process from application to passport issuance typically takes three to five months.

After obtaining citizenship, there are no residency or visit requirements. Citizenship is permanent once granted, and the entire renewal process can be completed remotely without travelling to Nauru. Nauru citizenship does not automatically create tax residency — there are no tax obligations for non-residents, as Nauru has no personal income tax on foreign-sourced income for non-residents.

Frequently Asked Questions About Nauru CBI Eligibility

Can I Include My Siblings in a Nauru CBI Application?

Yes. Nauru is one of the few CBI programmes that permits the inclusion of siblings. Each sibling incurs an additional surcharge of USD 15,000 on top of the standard application and due diligence fees.

Is There an Interview Requirement for Nauru CBI?

Yes. Every principal applicant must attend a mandatory interview conducted by an independent due diligence firm commissioned by the Nauru Program Office. The interview is part of the enhanced due diligence process and assesses the applicant's background, motivations, and source of funds.

Does Nauru Allow Dual Citizenship?
