Nauru Citizenship by Investment: Cost and Fees for 2026

Last updated: March 2026

For globally mobile investors and their families, securing a second citizenship is one of the most strategic decisions they will ever make — offering enhanced travel freedom, a wealth-preservation structure, and a meaningful plan B for an unpredictable world. Nauru, the world's smallest island republic nestled in the Central Pacific, has emerged as a noteworthy addition to the investment migration landscape, offering a streamlined citizenship by investment pathway that rewards those who act decisively. Understanding the precise Nauru CBI cost and fees is the essential first step in evaluating whether this programme aligns with your personal and financial objectives for 2026.

What Is the Nauru Citizenship by Investment Programme?

The Nauru Citizenship by Investment Programme is a government-authorised initiative that allows qualifying foreign nationals to obtain full Nauruan citizenship — and the passport that accompanies it — by making a prescribed financial contribution to the Republic of Nauru. Unlike investment migration programmes tied to real estate or enterprise funds, Nauru's pathway is structured as a direct donation to the state, channelled into national development priorities such as infrastructure, education, and economic diversification.

Nauru is a sovereign island nation in Micronesia with a population of fewer than 12,000 people. It gained independence in 1968 and has long maintained diplomatic relationships with a number of major economies. The programme is administered under the legislative framework of the Nauru Government and is processed through authorised and licensed agents — making the choice of a reputable consultancy partner, such as Mirabello, of paramount importance.

This programme sits within a broader category of citizenship by investment opportunities available globally. If you are comparing your options, our comprehensive guide to the best citizenship by investment programmes offers a valuable overview of how Nauru compares to other leading jurisdictions.

Nauru CBI Cost and Fees: A Full Breakdown for 2026

When assessing the Nauru CBI cost and fees, it is important to distinguish between the government's required contribution, due diligence fees, processing fees, and professional service fees. Below is a transparent breakdown of the principal costs associated with an application in 2026.

Government Contribution (Non-Refundable Donation)

• Single applicant: $105,000 USD
• Main applicant + spouse: $135,000 USD
• Family of up to four (main applicant, spouse, and two dependants): from $150,000 USD
• Each additional dependant over four: approximately $10,000 USD per person

These contributions are paid directly to the Government of Nauru and are non-refundable, regardless of the outcome of the application. All amounts are denominated in United States Dollars.

Due Diligence Fees

• Main applicant: $5,000 USD
• Spouse: $3,000 USD
• Dependants aged 16 and above: $2,000 USD per person
• Dependants under 16: $500 USD per child

Due diligence fees cover the cost of thorough background screening conducted by the Nauru government and its appointed international screening partners. This is a non-negotiable element of the programme and is paid regardless of application outcome.

Government Processing Fees

• Main applicant: $1,500 USD
• Each additional family member: $500 USD

Passport Issuance Fees

Upon successful approval, each successful applicant will be required to pay a passport issuance fee of approximately $300–$500 USD per passport, payable to the Nauru government.

Professional Service Fees

Mirabello Consultancy charges a transparent professional service fee for the full management of your application, from initial eligibility assessment and document preparation through to post-approval support. These fees are discussed in full during your free initial consultation and are structured to reflect the complexity and scope of your family's application. We do not impose hidden costs or surprise charges.

Summary: Total Investment Estimate

For a single applicant, the all-inclusive estimated investment — covering the government contribution, due diligence, processing fees, and professional services — typically begins at approximately $115,000–$125,000 USD. For a family of four, total costs generally range from $165,000–$185,000 USD, depending on the ages of dependants and the complexity of the application.

Investment Options: How the Nauru Programme Works

Unlike multi-route programmes such as those in St Kitts & Nevis or Grenada, the Nauru Citizenship by Investment Programme currently operates via a single investment route: a non-refundable government contribution. There is no real estate purchase option, no government bond route, and no enterprise investment pathway at this time.

This simplicity is one of the programme's distinguishing strengths. The straightforward donation model reduces administrative complexity, minimises the risk of asset-side complications, and generally results in a more streamlined processing experience than programmes involving property acquisition or fund subscriptions. Investors are not required to manage an ongoing investment asset or worry about exit strategies.

All contributions are remitted by bank wire transfer through a licensed agent, directly into designated government accounts. Mirabello Consultancy facilitates this process on your behalf, ensuring full compliance with both Nauru's requirements and international anti-money-laundering standards.

Eligibility Requirements for Nauru Citizenship by Investment

The Nauru programme maintains clearly defined eligibility criteria designed to uphold the integrity and international standing of the Nauruan passport. Applicants must satisfy all of the following conditions:

• Age: The main applicant must be at least 18 years of age at the time of application.
• Clean criminal record: Applicants must have no criminal convictions and must not be the subject of ongoing criminal investigations or proceedings in any jurisdiction.
• Good health: All applicants must undergo a medical examination and provide evidence of no serious communicable diseases.
• Financial standing: Applicants must demonstrate that the source of their investment funds is lawful and legitimate. Comprehensive source-of-funds and source-of-wealth documentation will be required.
• No sanctions exposure: Applicants must not appear on international sanctions lists maintained by the UN, EU, US OFAC, or equivalent bodies.
• No prior visa refusals from certain countries: While not an automatic disqualifier, a history of visa refusals from certain jurisdictions will be assessed as part of due diligence.
• No residency requirement: Applicants are not required to reside in, visit, or even travel to Nauru at any stage of the application process.

Nauru does not currently permit dual citizenship applications from nationals of all countries — applicants should verify their home country's position on dual nationality as part of their pre-application planning. Our advisors at Mirabello can assist you in navigating this consideration confidentially and professionally.

The Application Process: Step by Step

The Nauru CBI application process is designed to be efficient and transparent. Below is a summary of the key stages as they typically unfold with Mirabello Consultancy managing your file:

1. Initial Consultation and Eligibility Assessment — We conduct a thorough review of your personal profile, including nationality, criminal background, source of wealth, and family composition. This is offered at no charge. Book your free consultation here.
2. Document Collection and Preparation — Our team provides you with a detailed document checklist and assists in the preparation, notarisation, apostilling, and translation of all required materials. Typical documents include a valid passport, birth certificate, police clearance certificates, bank statements, professional references, and medical certificates.
3. Application Submission — Once all documents are verified and the application is complete, we submit on your behalf to the authorised Nauru government processing unit via a licensed agent channel.
4. Due Diligence Review — The Nauru government and its appointed international due diligence partners conduct background checks on all adult applicants. This is the most time-intensive stage and typically takes 8–14 weeks.
5. Approval in Principle — Upon satisfactory completion of due diligence, the government issues an Approval in Principle letter, which triggers payment of the government contribution and remaining fees.
6. Contribution Payment — All government fees and contributions are remitted by bank wire. Mirabello provides full payment instructions and confirmation receipts.
7. Citizenship Certificate and Passport Issuance — Following confirmed receipt of payment, the government issues the Certificate of Citizenship and the Nauru passport for each approved applicant.

Timeline: How Long Does the Nauru CBI Process Take?

One of the most practical questions for any investor is how quickly the process can be completed. Processing times for the Nauru Citizenship by Investment Programme typically range from 3 to 6 months from the date of complete application submission to receipt of the passport.

Factors that may influence the timeline include the completeness of documentation at submission, the complexity of the applicant's background (number of countries of residence, professional history, business interests), and current government processing volumes. Mirabello's meticulous document preparation process significantly reduces the likelihood of requests for additional information, which are the most common source of processing delays.

There is currently no official expedited processing track for the Nauru programme. Applicants requiring a faster solution may wish to consider programmes such as Vanuatu's Development Support Programme, which can be processed in as little as 30–60 days in certain circumstances.

Benefits of Nauru Citizenship: What Does the Passport Offer?

The Nauru passport delivers a compelling set of privileges for globally mobile individuals and families. Key benefits include:

• Visa-free and visa-on-arrival access to approximately 90 countries and territories, including the full Schengen Zone (26 European countries), the United Kingdom, Ireland, Singapore, and Hong Kong.
• No personal income tax for Nauruan citizens on income earned outside of Nauru.
• No capital gains tax, inheritance tax, or wealth tax at the Nauruan level.
• Full citizenship — not mere residency — conferring the right to a Nauruan passport, with all attendant privileges of nationality.
• Citizenship for life, with the ability to pass citizenship to children born after naturalisation.
• No residency obligation — citizens may live anywhere in the world without risk to their Nauruan citizenship status.
• An additional layer of global mobility — particularly valuable for nationals of countries whose passports offer limited travel access.

While the Nauru passport's visa-free access does not yet match the reach of Tier-1 Caribbean passports such as those of Grenada or St Kitts (which offer closer to 140–150 countries), it provides a meaningful upgrade for investors from markets such as the Middle East, South Asia, South-East Asia, and Africa, and represents an accessible entry point into the investment citizenship market.

Family Inclusion in the Nauru CBI Programme

One of the programme's most practical advantages is the ability to extend citizenship to qualifying family members within the same application, making it a genuinely family-centred solution. The following dependants may be included:

• Spouse or legal partner of the main applicant.
• Dependent children under the age of 18, or under 25 if enrolled in full-time tertiary education and financially dependent on the main applicant.
• Dependent parents aged 55 or above who are financially dependent on the main applicant.
• Dependent siblings under 18 in certain qualifying circumstances.

Each additional family member incurs both a contribution increment and the relevant due diligence fees as outlined above. All adult dependants aged 16 and over are subject to the same background screening process as the main applicant.

Mirabello strongly recommends including all qualifying family members in a single application where possible, as adding dependants at a later stage involves a separate application process and additional costs.

Frequently Asked Questions: Nauru Citizenship by Investment

The minimum government contribution for a single applicant is $105,000 USD. When due diligence fees, processing fees, and professional service fees are included, the total investment for a single applicant typically begins at approximately $115,000–$125,000 USD.

How long does the Nauru CBI application process take?

Processing times for the Nauru Citizenship by Investment Programme typically range from 3 to 6 months from the submission of a complete application. The due diligence review stage generally accounts for the majority of this timeframe.

Do I need to travel to or live in Nauru to obtain or keep my citizenship?

No. There is no requirement to visit, reside in, or maintain any physical presence in Nauru at any point during the application process or following the grant of citizenship. The entire process can be managed remotely through a licensed agent such as Mirabello Consultancy.

How many countries can a Nauruan passport holder visit without a visa?

Nauruan passport holders currently enjoy visa-free or visa-on-arrival access to approximately 90 countries and territories, including all 26 countries of the Schengen Area, the United Kingdom, Ireland, Singapore, and Hong Kong.

Can I include my spouse and children in my Nauru CBI application?

Yes. The programme allows for the inclusion of a spouse, dependent children (up to age 18, or 25 if in full-time education), and dependent parents aged 55 and above. Each additional dependant incurs incremental government contributions and due diligence fees. A family of four (main applicant, spouse, and two dependants) typically requires a total government contribution starting from $150,000 USD.

Is the Nauru contribution refundable if my application is refused?

No. The government contribution is non-refundable in all circumstances, including in the event of application refusal. Due diligence fees are similarly non-refundable. This is why thorough pre-application eligibility screening — as conducted by Mirabello prior to submission — is of critical importance.

Does Nauru allow dual citizenship?

Nauru itself permits its citizens to hold other nationalities. However, whether obtaining Nauruan citizenship affects your existing citizenship depends entirely on the laws of your current country of nationality. Mirabello's advisors will assess this on a case-by-case basis during your initial consultation.
