A second citizenship can work as a practical Plan B: an extra place to live or relocate if plans change. Citizenship by investment programmes in Africa and Oceania start at $90,000 and can grant citizenship in as little as 2 months, with access to an oceanfront lifestyle.
For stronger global mobility and a longer programme track record, applicants may consider more established but higher-cost options in the Caribbean.
This guide compares the cheapest citizenship by investment programmes in 2026, their costs, timelines, and factors beyond the headline investment amount.
What is citizenship by investment?
Citizenship by investment is a legal way for foreign nationals to obtain citizenship in another country by making an economic contribution. The rules are set by each country’s national legislation and administered by the relevant government authority. Investment routes vary by country, with the most popular options being a non-refundable fund contribution and the purchase of real estate.
Successful applicants receive full citizenship, including a passport and the civil rights of a national. In most cases, they do not need to live in the country before applying, pass a language test, or wait through a long naturalisation period.
Common eligibility requirements across citizenship by investment, CBI, programmes include:
- Minimum age of 18.
- Clean criminal record.
- Proof of the legal source of funds and source of wealth.
- Valid health insurance or a medical clearance certificate.
- No record on international sanctions lists.
- No serious illnesses.
For high-net-worth applicants, citizenship by investment can provide several practical benefits: a second passport with wider visa-free travel, the option to include family members in one application, full citizenship without relocation, tax optimisation, and greater flexibility for estate planning and succession.
What are the cheapest citizenship by investment programmes in 2026?
Citizenship by investment programmes differ in more than just price. Some focus on low entry thresholds, others on stronger passports, faster processing, broader family inclusion, or investment options that allow capital recovery.
The overview below compares the main citizenship by investment programmes available in 2026, highlighting their minimum investment requirements.
Citizenship by investment programmes at a glance
In 2026, the lowest-cost citizenship by investment programmes are offered by São Tomé and Príncipe and Nauru, with entry thresholds of $90,000, followed by Vanuatu at $130,000. However, cost is not the only factor applicants consider. Processing reliability, Due Diligence standards, passport strength, family inclusion rules, and the programme’s track record also shape the final choice.
Caribbean citizenship by investment programmes remain especially popular. They consistently hold the top 5 positions in the CBI Index and are valued for their established procedures, long operating history, and wider market recognition. In the ranking, the 5 Caribbean countries are followed by Nauru, Vanuatu, Türkiye, São Tomé and Príncipe, and Egypt[1]Source: CBI Index — 2025 Report.
The cheapest citizenship by investment programmes are:
- São Tomé and Príncipe — $90,000.
- Nauru — $90,000.
- Vanuatu — $130,000.
- Dominica — $200,000.
- Antigua and Barbuda — $230,000.
- Grenada — $235,000.
- St Lucia — $240,000.
- St Kitts and Nevis — $250,000.
- Egypt — $250,000.
- Türkiye — $400,000.
Though São Tomé and Príncipe and Nauru have some of the lowest entry costs, their options are non-refundable. Applicants who want to preserve capital may prefer higher-cost routes in the Caribbean, Egypt, or Türkiye, where investments can usually be redeemed after 3—7 years.
How do headline donation costs compare to the true total cost
The minimum investment shows the amount required to qualify for a citizenship by investment programme. It is not the full cost of the application. Applicants also pay related expenses, and the final amount depends on the number of family members included.
The main related expenses are:
- Contribution or investment — the required donation, property purchase, deposit, or other investment.
- Government and application fees — administrative charges paid to the programme authority.
- Due Diligence fees — background check fees, usually charged for each adult applicant.
- Dependent fees — additional charges for a spouse, children, parents, or other eligible family members.
- Document preparation costs — translation, notarisation, certification, apostille, and legalisation of supporting documents.
- Legal and professional fees — authorised agent and advisory fees paid separately.
The real cost of citizenship by investment is measured by the all-in amount, not the headline contribution.

8. Türkiye citizenship by investment

The real estate route, however, can offer a practical upside: investors may benefit from property price growth and potential capital appreciation. The programme is regulated by Turkish Citizenship Law No. 5901 and the Regulation on the Implementation of the Turkish Citizenship Law[9]Source: Türkiye CBI programme official website.
Passports can be obtained in around 8 months. Turkish citizens can apply for multiple-entry visas:

The required investment does not depend on the investor’s family composition. A spouse and children under 18 can be included without increasing the threshold.
After 3 years, the investor can exit the investment. If the real estate is sold, the next buyer will not be able to use the same property to apply for Türkiye citizenship by investment.
Real estate remains the most popular route. Property prices in Türkiye have grown sharply in recent years, and investors can buy residential or commercial property. A land plot also qualifies if it has a building worth at least $400,000 or if a building permit has been issued. Shares in property do not qualify.
Several properties can be combined to reach the $400,000 threshold if each already has a TAPU, the official title deed proving ownership. If the TAPU has not yet been issued, the applicant must provide a preliminary sales agreement listing all the properties.
Real estate purchase is the cheapest route to Türkiye citizenship by investment. The table below shows the estimated total cost by family size.

Step-by-step citizenship by investment application process
Based on Immigrant Invest’s experience, obtaining citizenship by investment takes between 2 and 10 months, depending on the jurisdiction. Processing times vary according to the programme’s Due Diligence procedures, application requirements, and government workload.
The fastest options are also the most affordable ones. Nauru, São Tomé and Príncipe, and Vanuatu offer the lowest investment thresholds among CBI programmes and can grant citizenship in 2—3 months.
Caribbean programmes take longer due to their multi-layered Due Diligence procedures and mandatory interviews, while Türkiye and Egypt often require more time to complete the investment and citizenship process.

Preliminary Due Diligence
Before documents are collected or funds are committed, Immigrant Invest conducts a preliminary review to assess the applicant's eligibility and identify potential risks.
The internal compliance team checks sanctions lists, politically exposed person status, adverse media, criminal records, source of funds, and previous visa or immigration refusals. This early assessment helps reduce the risk of rejection and allows potential issues to be addressed before the application process begins.

Up to 6 months
Submitting application and undergoing Due Diligence
Immigrant Invest submits the completed application to the relevant Citizenship by Investment Unit or equivalent authority. Due Diligence checks are mandatory for all applicants over 18. In some jurisdictions, screening starts earlier:
- 17 and over — Grenada;
- 16 and over — St Kitts and Nevis, Dominica, St Lucia, and Nauru;
- 12 and over — Antigua and Barbuda.
Caribbean CBI programmes also include a mandatory Due Diligence interview. It is usually held online. The interviewer reviews the applicant’s background, source of funds, business activities, travel history, and reasons for obtaining a second citizenship. The goal is to check whether the application details are accurate and whether the applicant is credible.
Applicants also provide biometrics. Vanuatu and St Kitts and Nevis require an in-person appointment for biometric collection.
In Türkiye and Egypt, competent state authorities carry out Due Diligence as part of the citizenship application. These countries do not have a separate paid Due Diligence stage.

Up to 5 months
Approval, oath, and passport issuance
After successfully passing all checks, the competent authority issues an approval letter confirming the grant of citizenship.
Some programmes require applicants to take an oath or affirmation of allegiance before citizenship is formally granted. Once all requirements have been met, a citizenship certificate is issued as official proof of nationality.
Passport applications are then processed, and passports are issued within several weeks. Validity periods vary by country but generally range between 5 and 10 years.

What do CBI applicants need to know about compliance and bankability?
CBI applicants must prove the legal origin of their funds, show a transparent personal and business background, and understand how banks may view their new passport.
Immigrant Invest reviews each case for both programme compliance and bankability. The goal is to prepare a clean source-of-funds file, avoid delays, and reduce future questions from banks or tax authorities.
Source-of-funds documentation
A clean source-of-funds evidence pack must show where the investment money came from and prove that it was earned, taxed, and transferred legally. The documents should trace the specific funds being invested back to verified income, business profits, dividends, asset sales, inheritance, or another legitimate source.
The pack usually includes:
- personal and business tax returns for the past 3—5 years;
- bank statements for all significant accounts, usually covering the past 6—12 months or longer if required;
- audited financial statements if the applicant owns or operates a business;
- corporate documents, such as certificates of incorporation, shareholder registers, and ownership records, if the wealth comes from business activities;
- documents confirming the sale of assets, such as property sale agreements, share purchase agreements, or proof of tax paid;
- explanation letters for large, irregular, or one-off transactions;
- narrative explanation of the origin of wealth, showing how all documents connect to the funds being invested.
If the CBI applicant has a complex ownership structure, such as trusts, offshore holding companies, or assets in several jurisdictions, the evidence pack should also include a clear ownership diagram. In many cases, independent legal opinions may be needed to confirm beneficial ownership.
Standard document burden
Each CBI programme has its own document requirements, but most applications follow a similar core checklist. Applicants should prepare identity documents, civil status records, police clearances, medical forms, financial references, and evidence of the lawful source of funds.
The standard document pack usually includes:
- valid passport, typically with at least 6 months’ validity and blank pages;
- national identity card;
- certified birth certificate;
- marriage certificate, divorce decree, or other civil status documents where applicable;
- proof of legal name change, if the applicant has ever changed their name;
- apostilled police clearance certificates from every country where the applicant has lived for 12 months or more in the past 10 years;
- medical examination certificate or health declaration, completed by an approved physician if the programme requires it;
- certified passport-size photographs, prepared according to the programme’s exact specifications;
- bank reference letter;
- professional reference letter, if required;
- source-of-funds documents, such as tax returns, bank statements, and corporate records;
- dependency proof documents for children, parents, or other dependants included in the application.
Non-English documents must be translated by a certified translator. Copies of passports, birth certificates, and other key documents usually need to be notarised, apostilled, or otherwise legalised according to the rules of the selected programme.

Document preparation can take 6—12 weeks, especially for applicants with complex residence or citizenship histories. Delays often arise when police certificates must be obtained from several countries, when documents need legalisation in different jurisdictions, or when certificates must be reformatted to match a programme’s exact requirements.
Bankability by programme
Passport origin can affect private-bank account opening, ongoing compliance checks, and correspondent banking relationships. Banks assess not only the passport itself; they also consider the client’s tax residence, source of funds, source of wealth, sanctions exposure, political exposure, and the reputation of the citizenship programme.
St Kitts and Nevis, Dominica, and Grenada usually offer the strongest private-bank acceptance. These programmes have long operating histories, established Due Diligence systems, and oversight within the Eastern Caribbean framework.
Antigua and Barbuda and St Lucia are also broadly accepted, although some banks may ask additional questions depending on their internal policy on citizenship by investment.
Türkiye is generally bankable, especially because it is a large economy with an established banking system. However, applicants should expect detailed compliance checks because the programme is investment-based and Türkiye was previously subject to enhanced monitoring by the Financial Action Task Force, the international body that sets standards for preventing money laundering and terrorist financing.
Egypt may be accepted by banks, but its CBI programme has a shorter international track record than the Caribbean options. Banks may review the case more closely, especially where the applicant’s wealth, tax residence, or business interests are linked to higher-risk jurisdictions.
Vanuatu carries the highest bankability risk among the established programmes. International organisations have raised concerns about the country's anti-money laundering and counter-terrorist financing controls, as well as the impact of its CBI programme on correspondent banking relationships. As a result, some banks may apply enhanced Due Diligence or be reluctant to onboard clients using a Vanuatu passport.
São Tomé and Príncipe and Nauru have no comparable track record with international private banks. Applicants should expect more questions and less predictable outcomes.
Applicants should inform their main private bank and tax adviser after receiving a new citizenship. A second passport may trigger a Common Reporting Standard review, updates to the client’s tax profile, and additional internal compliance checks at the bank.

Understanding Due Diligence: what it involves and how to prepare
Risks and pitfalls when choosing the cheapest citizenship by investment programme
A citizenship by investment programme that appears cheaper at first glance may involve higher family costs, stricter banking scrutiny, changing regulations, or unexpected fees.
Applicants should consider not only the entry price but also long-term factors such as compliance requirements, bankability, processing timelines, and the programme's stability.
Rules that may change
The cheapest programme today may not stay the cheapest for long. Minimum investments, government fees, family charges, and eligibility rules can change with little notice.
The 2024 Caribbean repricing showed how quickly the market can shift: five countries raised their minimum contributions at the same time, and two previously cheaper options lost their price advantage almost overnight.
Newer programmes, such as São Tomé and Príncipe and Nauru, also need extra caution. Their fees, visa-free access, and administrative rules are still developing, so older cost comparisons may quickly become outdated.
Weak passport reputation
A low price can come with weaker acceptance by banks, visa authorities, or correspondent banking partners. Vanuatu is the clearest example. Its citizens permanently lost visa-free access to the Schengen Area in February 2025, which reduced the passport’s practical value for applicants connected with Europe.
Before choosing a programme, applicants should look at more than visa-free access and price. Programme history, compliance standards, IMF comments, and OECD or FATF concerns can all affect how the passport is treated later.
Higher final cost
The headline investment amount rarely shows the full cost of citizenship. Applicants also pay government fees, Due Diligence fees, legal fees, dependent charges, translation costs, notarisation, and apostilles. These extra expenses can add around 10% for a single applicant and up to 50% for families.
A safe comparison always starts with a line-by-line estimate for the exact family size and selected investment route.
Poor source-of-funds file
Incomplete or unclear source-of-funds documents are one of the most common reasons for delays or refusals. The authorities need to see where the investment money came from and how it moved into the applicant’s account. Business owners, trust beneficiaries, and applicants with assets in several countries often need more time to prepare this evidence.
The source-of-funds file should be prepared before the applicant signs property documents or commits funds to a programme. Otherwise, the investment may be ready before the compliance file is strong enough.
Longer real timelines
Official processing times are best treated as optimistic estimates. Applications can take longer because of notary appointments, police certificates, document legalisation, government backlogs, or requests for additional information. The more countries, businesses, or dependants involved, the higher the chance of delay.
Before starting the process, applicants should confirm current timelines and prepare for a longer schedule than the fastest published estimate.
How Immigrant Invest helps find the most cost-effective CBI option
Immigrant Invest is a consulting company specialising in citizenship and residence by investment. We have worked in investment migration for over 20 years and have helped more than 10,000 clients obtain second citizenship or residence.
We are licensed to work with Caribbean citizenship by investment programmes, Vanuatu, and São Tomé and Príncipe. Our role is to compare the available options, calculate the real cost for each family, check compliance risks in advance, and guide applicants through every stage of the procedure.
The process is built around six key steps:
- Initial consultation. We discuss the applicant’s goals, family structure, timeline, budget, and possible restrictions, then outline the most suitable CBI options.
- Compliance pre-check. An AML Compliance Officer reviews the applicant’s background, flags possible risks, and prepares a tailored document checklist. If the check is passed, we agree on the jurisdiction and sign an agreement. If risks appear, we offer an alternative solution.
- Strategy outline. We agree on the application route, timeline, and sequence of steps. Each client works with a named advisor who coordinates the process.
- Document build-out. The Legal Department prepares the source-of-funds file, checks supporting documents, coordinates certifications and sworn translations, and prepares the applicant for a Due Diligence interview if needed.
- Filing and follow-up. We submit the application, monitor the review, respond to authority requests, and send regular status updates.
- Post-approval care. After approval, we help with passport issuance, document renewals, replacements, banking, property matters, and relocation logistics if needed.
Professional guidance helps applicants compare programmes on a like-for-like basis, avoid costly mistakes, and select the option that best matches their goals.
Key takeaways about the cheapest citizenship by investment programmes
- Citizenship by investment programmes in São Tomé and Príncipe, Nauru, and Vanuatu offer the lowest-cost entry points. The minimum investment starts at $90,000 in São Tomé and Príncipe and Nauru, while Vanuatu starts at $130,000.
- The cheapest route is not the most flexible one. All three lowest-cost options are non-refundable, with only Vanuatu offering partial recovery over time through one of its routes.
- Caribbean programmes cost more, but they come with a longer track record. St Kitts and Nevis is the oldest CBI programme and remains one of the leading choices among investors. Dominica offers the lowest minimum threshold in the Caribbean, starting at $200,000.
- The Caribbean five can be a stronger choice for applicants who value global mobility, programme reputation, and predictable procedures. Their passports are more established in banking and immigration systems than newer low-cost options.
- Egypt and Türkiye are alternatives to donation-based routes. Egypt keeps the same minimum investment threshold regardless of family size, while Türkiye can offer capital appreciation through real estate investment.
- The headline donation is only the starting point. A true CBI budget should include Due Diligence, application, dependent, legal, translation, and document fees. These extra costs can increase the final budget by $15,000—50,000 or more.
