Nauru Citizenship by Investment Cost Requirements 2026

Last updated: March 2026

For internationally mobile investors and high-net-worth families exploring a second citizenship, the Pacific island nation of Nauru has quietly emerged as one of the more accessible and cost-effective pathways to a new passport in 2026. Whether your priority is expanding your global travel freedom, securing a Plan B for your family, or simply diversifying your personal portfolio of nationalities, understanding the Nauru CBI cost requirements in full — from the headline investment figure through to government fees, due diligence charges, and professional advisory costs — is essential before committing to any programme. At Mirabello Consultancy, we have helped discerning clients navigate citizenship by investment programmes across the globe, and in this comprehensive guide we set out everything you need to know about the Nauru programme in 2026.

What Is the Nauru Citizenship by Investment Programme?

The Republic of Nauru, a small island nation located in Micronesia in the central Pacific Ocean, introduced its Citizenship by Investment (CBI) programme as part of a broader strategy to attract foreign direct investment and diversify its national revenue base. The programme allows eligible foreign nationals to acquire Nauruan citizenship — and with it a Nauruan passport — in exchange for a qualifying financial contribution to the country's National Development Fund (NDF) or through other approved investment channels.

What distinguishes the Nauru CBI programme from many of its Caribbean and European counterparts is its relatively lean administrative structure and the absence of a physical residency requirement. Applicants are not required to visit Nauru before, during, or after the application process, and there is no minimum number of days per year that new citizens must spend on the island. This makes the programme especially attractive to global entrepreneurs and business families whose schedules do not accommodate prolonged stays in a single location.

Nauru is a sovereign state and a member of the United Nations, the Commonwealth of Nations, and the Pacific Islands Forum. Its passport, while not as widely recognised as those of established Caribbean CBI jurisdictions, nonetheless offers meaningful travel utility, particularly for investors from countries with restricted passports. The programme is administered by the Nauru Citizenship Secretariat and is supported by a select group of authorised agents worldwide — Mirabello Consultancy being one such authorised advisory partner.

Nauru CBI Cost Requirements: Investment Options Explained

Understanding the precise Nauru CBI cost requirements means looking beyond the headline investment figure and accounting for all associated fees. Below is a detailed breakdown of the costs involved under each available route.

National Development Fund (NDF) Contribution

The primary and most widely utilised pathway is a non-refundable contribution to Nauru's National Development Fund. The NDF route is straightforward: funds are paid directly to the government and are not tied to any commercial project or real estate asset. The contribution amounts in 2026 are structured as follows:

• Single applicant: From approximately USD $105,000
• Main applicant + spouse: From approximately USD $135,000
• Family of four (main applicant, spouse, and two dependent children): From approximately USD $150,000
• Additional dependants (each): approximately USD $10,000 – $15,000 per additional family member

These figures represent the government contribution only. Additional costs — detailed below — are payable on top of this amount.

Additional Government and Administrative Fees

Beyond the core NDF contribution, applicants should budget for the following fees:

• Due diligence fee (main applicant): approximately USD $5,000 – $7,500
• Due diligence fee (spouse and adult dependants): approximately USD $3,000 – $5,000 each
• Application processing fee: approximately USD $1,500 – $2,500 per person
• Passport issuance fee: approximately USD $300 – $500 per passport
• Oath of allegiance/naturalisation fee: a nominal administrative charge, typically under USD $500

Professional Advisory Fees

Working with a reputable authorised agent such as Mirabello Consultancy adds a professional advisory fee that varies depending on the complexity of your case, the number of family members included, and the scope of services required. Our advisory fees are transparent, disclosed in full at the outset, and reflect the Swiss standard of precision and client care that defines our practice. We encourage all prospective applicants to book a free consultation to receive a personalised cost illustration for their specific family situation.

Total all-in investment estimate for a single applicant: approximately USD $115,000 – $130,000, inclusive of all government fees and professional services.

Total all-in investment estimate for a family of four: approximately USD $165,000 – $185,000, inclusive of all fees.

Eligibility Requirements for Nauru CBI in 2026

The Nauru Citizenship by Investment Programme maintains clear eligibility criteria designed to ensure that citizenship is extended only to individuals of good character and proven financial standing. The principal requirements are as follows:

• Age: The main applicant must be at least 18 years of age.
• Character: A clean criminal record is mandatory. Any previous convictions for serious offences will result in disqualification.
• Health: Applicants must not pose a public health risk. A medical examination may be required.
• Source of funds: The investment must derive from legitimate and verifiable sources of wealth. Comprehensive source-of-funds documentation is a cornerstone of the due diligence process.
• No adverse history: Applicants must not have been denied a visa or entry to a country with which Nauru maintains diplomatic relations, and must not be subject to international sanctions.
• Genuine investment intent: While the NDF route is a straightforward contribution rather than a commercial investment, applicants must demonstrate a genuine intent to honour the obligations of Nauruan citizenship.

Dual citizenship is permitted in Nauru, meaning you are not required to renounce your existing nationality. This is a significant advantage for investors who wish to retain the rights and privileges associated with their country of origin.

Application Process: Step by Step

The Nauru CBI application process is methodical and well-structured. Below is a step-by-step overview of the journey from initial enquiry to passport in hand.

1. Step 1 — Initial consultation and eligibility assessment: Mirabello Consultancy conducts a comprehensive review of your personal and financial profile to confirm eligibility and identify any potential issues before the formal application is submitted.
2. Step 2 — Document preparation: Our team assists you in compiling the required documentation package. This typically includes certified copies of passports, birth and marriage certificates, police clearance certificates, bank statements, source-of-wealth declarations, and professional references.
3. Step 3 — Submission of formal application: The completed application is submitted to the Nauru Citizenship Secretariat through the authorised agent channel. All due diligence fees are paid at this stage.
4. Step 4 — Government due diligence review: The Secretariat undertakes a rigorous multi-layer background check on all adult applicants. This is the most time-intensive phase of the process.
5. Step 5 — Approval in principle: Upon successful completion of due diligence, the applicant receives an approval in principle letter from the Nauruan government.
6. Step 6 — Investment payment: Following approval in principle, the NDF contribution is transferred directly to the designated government account.
7. Step 7 — Oath of allegiance: Successful applicants take the oath of allegiance, which can in many cases be administered remotely or through a Nauruan diplomatic mission.
8. Step 8 — Passport issuance: Nauruan passports are issued and delivered to the applicant, completing the citizenship process.

Processing Times: How Long Does Nauru CBI Take?

Processing times for the Nauru Citizenship by Investment Programme typically range from 3 to 6 months from the date of formal submission, assuming all documentation is complete and no complications arise during due diligence. This timeline can be broken down approximately as follows:

• Document preparation and submission: 4 – 8 weeks (dependent on applicant responsiveness)
• Government due diligence review: 8 – 14 weeks
• Approval in principle to passport issuance: 3 – 6 weeks

It is important to note that incomplete applications or requests for additional documentation from the Secretariat can extend processing times. Mirabello Consultancy's meticulous document preparation approach is specifically designed to minimise delays and ensure your application proceeds as efficiently as possible.

Benefits of Nauru Citizenship: What Does the Passport Offer?

The Nauruan passport provides a range of meaningful benefits for internationally mobile investors and their families:

• Visa-free and visa-on-arrival access: Nauruan passport holders enjoy visa-free or visa-on-arrival travel to over 80 countries and territories, including all 27 Schengen Area member states, the United Kingdom, Ireland, Hong Kong, Singapore, and a wide range of Commonwealth nations.
• No residency requirement: There is no obligation to reside in Nauru before or after receiving citizenship, affording complete lifestyle flexibility.
• Dual citizenship permitted: Nauru allows you to maintain your existing nationality, ensuring no disruption to your current legal status or business activities.
• Family inclusion: A Nauruan passport can be obtained for your spouse, children, and in some cases other qualifying dependants as part of the same application.
• Lifetime citizenship: Citizenship is granted for life and can be passed to future generations in accordance with Nauruan nationality law.
• Plan B security: For investors from politically unstable or highly taxed jurisdictions, Nauruan citizenship provides a valuable insurance policy and an additional layer of global mobility.

Including Family Members in Your Nauru CBI Application

One of the most appealing features of the Nauru programme is its relatively inclusive approach to family reunification under a single application. The following family members may typically be included:

• Spouse or legally recognised partner of the main applicant
• Dependent children under the age of 18
• Dependent children aged 18 to 26 who are in full-time education and financially dependent on the main applicant
• Dependent parents or parents-in-law of the main applicant, subject to age and dependency criteria

Each adult family member included in the application must individually satisfy the character and health requirements and will be subject to their own due diligence assessment. Children under the age of 18 are not subject to the full due diligence process but will require standard documentation such as birth certificates and certified passport copies.

When planning a family application, it is particularly important to work with experienced advisers who can anticipate documentation requirements for multi-generational families. At Mirabello Consultancy, we take pride in providing the kind of personalised attention to detail that ensures no family member's inclusion is delayed or complicated by avoidable oversights.

How long does it take to obtain Nauru citizenship by investment?

The due diligence review by the Nauruan government accounts for the majority of this timeframe, generally taking 8 to 14 weeks.

Does Nauru allow dual citizenship?

Yes, Nauru permits dual citizenship. You are not required to renounce your existing nationality when acquiring Nauruan citizenship through the investment programme. This means you can retain all the rights and benefits associated with your current passport while also holding a Nauruan passport.

Do I need to visit Nauru to obtain citizenship?

No physical visit to Nauru is required as part of the Citizenship by Investment application process. There is also no residency requirement either before or after citizenship is granted. The oath of allegiance can in many cases be administered remotely or through a Nauruan diplomatic mission, making the process highly accessible for globally mobile applicants.

How many countries can I visit visa-free with a Nauru passport?

The Nauruan passport currently grants visa-free or visa-on-arrival access to over 80 countries and territories, including all 27 Schengen Area states, the United Kingdom, Ireland, Hong Kong, Singapore, and numerous Commonwealth nations. While this represents a more modest travel footprint than Caribbean CBI passports, it delivers meaningful mobility gains for investors from countries with more restricted passports.

Can I include my parents in a Nauru CBI application?

In many cases, dependent parents or parents-in-law of the main applicant may be included in a Nauru CBI application, subject to age thresholds and demonstrated financial dependency on the main applicant. Each parent included will be subject to their own due diligence review and an additional government fee. We recommend discussing your specific family composition with a Mirabello Consultancy adviser to confirm eligibility and cost implications.

Is the Nauru CBI investment refundable?

No. The contribution to Nauru's National Development Fund is a non-refundable donation. It is not a commercial investment, real estate purchase, or loan, and does not generate a financial return. The value exchange is the grant of citizenship and the associated benefits of a Nauruan passport rather than a monetary return on investment.
