Nauru Citizenship by Investment: Cost and Process Guide 2026

Last updated: March 2026

For the globally minded investor seeking an efficient route to a second passport, the Pacific island nation of Nauru has emerged as one of the more discreet and strategically compelling options in the citizenship by investment landscape. Whether your priorities centre on expanded visa-free travel, international tax planning, or securing a robust plan B for your family, Nauru's programme deserves serious consideration. In this comprehensive guide, Mirabello Consultancy walks you through everything you need to know about the Nauru CBI cost and process for 2026, giving you the clarity to make a truly informed decision.

What Is the Nauru Citizenship by Investment Programme?

The Nauru Citizenship by Investment Programme is an officially sanctioned government initiative that allows qualifying foreign nationals to obtain Nauruan citizenship — and with it a Nauruan passport — in exchange for a significant, non-refundable financial contribution to the country's development funds. The Republic of Nauru, a small island nation in Micronesia covering just 21 square kilometres, launched this programme as part of a broader strategy to diversify its economic base and attract international capital.

Unlike many golden visa schemes that initially grant residency before citizenship, Nauru's CBI programme leads directly to full citizenship and a passport. This direct-to-citizenship model is one of the key reasons it attracts high-net-worth individuals who value speed and simplicity. The programme is administered under Nauruan statute and supervised by the government's authorised agency, ensuring a transparent, legally structured process.

For prospective investors comparing their options, it is worth noting that Nauru sits alongside other direct citizenship programmes reviewed in our guide to the best citizenship by investment programmes globally.

Eligibility Requirements for Nauru Citizenship by Investment

Nauru maintains a thorough eligibility framework designed to ensure that only applicants of good character and genuine financial standing are approved. The programme is not restricted to applicants from particular nationalities, though individuals from certain sanctioned jurisdictions may be ineligible. Key eligibility criteria include:

• Age: The main applicant must be at least 18 years of age.
• Clean criminal record: No criminal convictions in any jurisdiction. A police clearance certificate from each country of residence over the past ten years is required.
• Good health: Applicants must submit a medical certificate confirming they do not present a public health risk.
• Legitimate source of funds: Applicants must demonstrate that the investment funds derive from lawful sources. Comprehensive source-of-wealth and source-of-funds documentation is mandatory.
• No reputational risk: Applicants must not be subject to international sanctions, and must not have previously been refused citizenship, residency, or a visa by Nauru or its partner assessment jurisdictions.
• No residency requirement: Physical presence in Nauru is not required prior to, during, or after the application. This is a fully remote process.

Dependent family members — including a legally married spouse, children under 18 (or up to 25 if in full-time education and financially dependent), and in certain cases dependent parents over 55 — may be included on the same application subject to the same due diligence standards.

The Application Process: Step by Step

The Nauru CBI process is structured in clearly defined stages. Working with an authorised and experienced firm such as Mirabello Consultancy significantly reduces the risk of delays caused by incomplete documentation or procedural errors.

Step 1: Initial Consultation and Eligibility Assessment

Your journey begins with a confidential consultation with one of our senior advisers. We assess your eligibility, discuss your objectives, and outline the documentation requirements relevant to your profile. This is also the stage at which we present a full, transparent cost illustration. Book your free consultation today.

Step 2: Appointment of Authorised Agent

All applications must be submitted through a government-authorised agent. Mirabello Consultancy works directly with authorised representatives to ensure your file is handled through the proper official channels.

Step 3: Document Preparation and Due Diligence

This is the most labour-intensive stage of the process. Applicants must gather and certify a comprehensive document pack, typically including:

• Certified copies of current passports and any previously held passports
• Birth certificates and, where applicable, marriage certificates
• Police clearance certificates from all countries of residence over the past 10 years
• Comprehensive source-of-wealth declaration with supporting financial documentation (bank statements, tax returns, business records)
• Medical examination certificate from an approved physician
• Professional reference letters
• Completed government application forms

All documents in languages other than English must be accompanied by certified translations.

Step 4: Submission and Government Due Diligence

Once the document pack is complete and verified by our team, the application is formally submitted to the Nauru government authorities. The government then conducts its own multi-layered due diligence review, which includes checks conducted by independent international agencies.

Step 5: Approval in Principle

Upon satisfactory completion of due diligence, the applicant receives a formal approval in principle. This triggers the payment of the government contribution and any outstanding fees.

Step 6: Oath of Allegiance and Certificate of Naturalisation

Following payment, applicants (or their authorised representatives) complete the oath of allegiance formalities. A certificate of naturalisation is then issued, formally conferring Nauruan citizenship.

Step 7: Passport Application and Issuance

With the naturalisation certificate in hand, the Nauruan passport application is submitted. Passports are typically issued within four to eight weeks of the naturalisation certificate being granted.

Processing Timeline: How Long Does Nauru CBI Take?

One of the most frequently asked questions we receive from prospective clients concerns processing times. The Nauru CBI process typically takes between 3 and 6 months from the date of formal application submission, assuming a complete and properly prepared file. The breakdown by stage is approximately as follows:

• Document preparation (Stage 3): 4–8 weeks, depending on the complexity of the applicant's profile and the speed with which documents such as police certificates are obtained
• Government due diligence review (Stage 4): 8–16 weeks
• Approval, payment, and oath formalities (Stages 5–6): 2–4 weeks
• Passport issuance (Stage 7): 4–8 weeks

It is worth noting that incomplete applications, requests for additional information, or complex personal circumstances can extend these timelines. Engaging an experienced advisory firm from the outset is the most effective way to minimise delays.

Benefits of Nauru Citizenship by Investment

Investors choose the Nauru programme not simply for the passport itself, but for the broader suite of strategic advantages it confers.

Visa-Free and Visa-on-Arrival Access

A Nauruan passport currently provides visa-free or visa-on-arrival access to over 90 countries and territories, including all 27 Schengen Area member states, the United Kingdom, Ireland, Singapore, Hong Kong, and numerous others. This represents a meaningful enhancement in global mobility for applicants from jurisdictions with more restrictive travel documents.

Favourable Tax Environment

Nauru does not impose income tax, capital gains tax, wealth tax, or inheritance tax on its citizens. For internationally mobile individuals engaged in legitimate wealth management planning, Nauruan citizenship can form one element of a broader, professionally structured international tax strategy. Mirabello Consultancy always recommends that clients seek independent legal and tax advice to understand the implications for their specific circumstances.

No Residency Requirement

Unlike many residency-first programmes — such as those we compare in our guide to the best golden visa investment programmes — Nauru imposes no requirement to spend any time in the country before, during, or after the application. This makes it ideally suited to busy entrepreneurs and business owners who cannot afford extended periods abroad.

Dual Citizenship Permitted

Nauru permits dual citizenship, meaning applicants do not need to renounce their existing nationality when obtaining Nauruan citizenship (subject to the laws of their home country permitting dual nationality).

Lifetime Citizenship

Nauruan citizenship obtained through investment is full, irrevocable citizenship — it is not temporary or subject to periodic renewal. It may also be passed on to future generations born after citizenship is obtained.

Family Inclusion: Bringing Your Loved Ones

The Nauru CBI programme is genuinely family-friendly. The following categories of dependants may typically be included in a single application:

• Spouse: Legally married spouses (same-sex couples should seek specific advice regarding Nauruan law).
• Dependent children: Unmarried children under 18 years of age. Children aged 18–25 who are in full-time education and financially dependent on the main applicant may also qualify, subject to documentation.
• Dependent parents: Parents and parents-in-law aged 55 or above who are financially dependent on the main applicant may be included, subject to an additional contribution and due diligence process.

Including family members increases the total investment required, but the cost-per-person efficiency improves significantly for larger family groups compared to submitting separate individual applications. Mirabello Consultancy will model the precise cost structure for your family during your free consultation.
