São Tomé and Príncipe Citizenship by Investment: The Complete Application Guide

Introduction: Africa’s Newest Citizenship Program in Context

Since this African island nation launched its citizenship by investment program last year, it has become one of the most discussed and sought-after. In 2026, São Tomé and Príncipe citizenship by investment is thriving thanks to its low threshold of only $90,000 for a single applicant, and convenient conditions for large families.

The application for a family of four requires only a $95,000 donation, and $5,000 for each additional dependent from the 5th member and on. 

This makes it the most cost-effective program, especially for families, and the most accessible one, with a flat fee of $5,000 and a per-applicant $750 fee for issuance of passport, naturalization letter, and a São Toméan ID. 

Mundo goes back to discussing one of the most popular migration routes available in 2026: São Tomé citizenship through a donation.

What São Tomé and Príncipe Offers Global Citizens in 2026

The past three decades have only shown us how crises get deeper and ever more serious. Historically, we have seen how crises rotate, alternating with periods of stability and prosperity across different regions; however, things are not so black and white anymore.

Countries that were considered safe and stable have become expensive, overcontrolled, and prone to geopolitical conflicts, while developing nations continue to struggle with volatility, high crime rates, and excessive inflation. In such a scenario, acquiring citizenship in a small, neutral, and stable country constitutes an outstanding Plan B that more and more families are pursuing.

Advantages of the São Tomé program

• Affordable citizenship program granting eligibility for $90,000
• Ideal for large families, as the additional contribution for each extra dependent is only $5,000
• Flexible stay requirements
• Stable political environment
• Rich biosphere and exuberant nature
• The country itself is a UNESCO Site
• Enhanced mobility
• Possibility of easier travel to key destinations
• Strategic location in the Gulf of Guinea
• Accepts de facto partners
• Children allowed until the age of 30
• Parents and grandparents allowed
• No nationality restrictions for eligibility
• Flat fee regardless of the number of dependents
• Contribution is made only once approved

Who Applies and Why: Profiles of Typical Candidates

Safe application: candidates from sanctioned nations

In line with the above, we see how citizens of certain countries struggle to obtain a second citizenship. It's strange how the world works, as those who need it the most find the doors closed to advantages that would help them considerably. Through a CBI application, they can obtain dual citizenship and a passport of a new nation that will help them expand their travel reach and found a safe relocation place.

The São Tomé and Príncipe program is open to all nationalities and doesn't stipulate any bans or restrictions, except for citizens of North Korea. Even so, they are not banned per se; their application simply cannot be processed because the citizenship unit cannot conduct due diligence on them.

Ideal citizenship for a large family

Its low contribution threshold makes it ideal for large families. At the time of writing, there's no other program to offer dual citizenship eligibility for $95,000 and four family members. This can't be found in St Kitts, Grenada, Vanuatu, or even Panama with its well-known residency visas.

If the family has more than four members, the requirement is to add only $5,000 for each additional dependent, a benefit that is better seized when the family is larger, as we can see in the infographic below. 

The following graph illustrates the minimum contribution for a family of six members: main applicant + 5 dependents. Furthermore, in São Tomé, each of them obtains the full rights that come with naturalization: issuance of passport, national ID, and passing citizenship to the next generations. 

Program Structure and Investment Options

Contribution Amounts for Single Applicants and Families

*The estimated total doesn't include legal fees, costs, or expenses. The above information is provided for a general overview, yet it should be confirmed during a formal consultation. 

What the National Development Fund Finances

Citizenship or residency through a contribution is becoming ever more popular as applicants seek to put their wealth into more meaningful uses. We see this trend not only in citizenship programs, but also in residency paths like the Portuguese Golden Visa.

The Iberian nation offers a 2-year renewable permit for those who contribute to cultural projects and heritage conservation initiatives. In São Tomé and Príncipe, efforts are directed towards sectors like education, infrastructure, eco-tourism, and sustainability. 

On its official website, the São Tomé government describes the benefited sectors. Part of the funds will help to develop renewable energy sources, which are important for protecting São Tomé's uniquely rich nature and the planet in general.

In line with this, ecotourism-related programs aim at promoting conservation as well as fostering awareness among locals, visitors, and tourists, encouraging them to enjoy nature with respect.

The funding of educational facilities and the development of public infrastructure will help consolidate the pillars of the nation and shape future generations, as we can read on the government’s official website.

Finally, some of the funds will be destined for the construction of a deep seaport that will strengthen the country's maritime connectivity.

Official Fees: Due Diligence, Processing, Passport Issuance

One of the program's best advantages is its flat submission fee, as it’s paid per application rather than per dependent. It is becoming clearer why the African nation constitutes an outstanding opportunity for large families. Although the fee is non-reimbursable, it's quite a good deal if we consider the costs of other similar CBIs.

Along the way, additional fees will be required to cover the certificate of registration, the issuance of the passport, and the national ID. In this case, the fee is $750 (see the table above), and is applied to each dependent. 

An important note on the São Tomé program is that dependents can be added after approval; only paying slightly larger fees. The fee for adding a spouse is $10,000; other additional dependents require $5,000, and newborns $500.

Mundo editor's opinion: "as Mundo's editor and the seniormost writer, I strongly believe that São Tomé CBI's best advantage is not necessarily its cost-effectiveness. For me, it's its availability that makes it an outstanding option. This is one of the few programs in the world that accepts all nationalities without recognizing bans or restrictions, except for North Korea, because the government cannot conduct proper due diligence on its citizens".

The Application Process Step by Step

Step 1: Pre-Screening and Engagement of a Licensed Agent

Your first step towards citizenship is choosing a licensed agent such as Mundo. Everything will begin with pre-screening by your assigned expert, who will review the details of your application, your current passport, the composition of your family, and your chances of passing the due diligence process satisfactorily. If you are open and don't hide anything from your Mundo expert, approval is almost 100% guaranteed.

Step 2: Document Collection - the Full Checklist

With the help of your Mundo expert, you must gather, notarize, and translate the following documents:

• Two application forms 
• Copy of your passport
• Copy of your birth certificate
• Second ID
• Four photographs (size 2x2), two must be certified
• Police records stating the absence of a criminal background
• Proof of source of funds
• Bank reference
• Utility bill, title deed or tenancy agreement as proof of address
• Medical examination to prove being in excellent health
• Marriage certificate (or divorce certificate, or certificate for the death of spouse, if applies)
• Affidavit of support (for dependents older than 18)

Step 3: Submission, Due Diligence, and Government Review

Once Mundo experts curate each document, your application will be submitted through us. This is the longest part of the process, and it's completely in the hands of the citizenship by investment unit. They will review all your documents and conduct strict due diligence. Only once you are cleared will you receive a letter of approval.

Step 4: Approval in Principle and Contribution Payment

The contribution is made after the approval is confirmed. If your application is rejected, you're not obliged to make the contribution, nevertheless, you won't get the submission fee back. When it comes to the donation, it can be made directly to the São Tomé and Príncipe government or through Mundo.

Step 5: Oath, Naturalization Certificate, and Passport Issuance

Step 5 is the previous step before becoming an official São Toméan citizen. The applicants must complete the naturalization process by making an oath, after which the government will issue a naturalization certificate, a national ID, and a passport.

Family Application

Spouses, Children, and Dependent Parents: Inclusion Rules

While all programs allow the inclusion of the spouse, not all of them accept de facto partners. São Tomé does. Furthermore, parents and grandparents are allowed from the age of 55, provided they are financially dependent on the main applicant.

When it comes to adding children, they can be included until the age of 30 as long as they are unmarried. It’s worth noting that all family members obtain citizenship, and citizenship is transferable to the next generations.

Adding Family Members After the Main Application

It is not unusual for a family to expand after approval, and the program contemplates this. If the applicant is remarried or new children are born, they can be included post-approval, although with a slightly higher fee.

Factors that may lead to rejection

Dependent children are divorced

The only condition for adding dependents is that they are unmarried; i.e., they have never been married before. Divorced children don't qualify as dependents. Therefore, if this fact is deliberately concealed and comes up during the review process, it may lead to rejection.

Hiding facts about the applicant or dependents

Concealing facts about the applicant or the dependents, like previous marriages, bank accounts, relationships with public figures, or former places of residence or citizenship, is a very bad practice. This kind of behavior doesn’t help; it backfires. All these details will be uncovered during due diligence and will only raise doubts about the honesty and good character of the applicant.

Failing to prove having a legit source of funds

The provided source of funds must check out, with the unit being able to prove that it's legit. Moreover, if during the process they find other undeclared sources with shady or unclear origins, the application may capsize.

Conclusion: São Tomé Citizenship and Realistic Expectations

Why Working with an Authorized Agent Is Non-Negotiable

In only a year, the São Tomé and Príncipe program has demonstrated to be reliable, compliant, and safe. It is, in our view, one of the best options available today and definitely the most affordable one.

If the application is pursued through an authorized agent such as Mundo, and if the applicant has impeccable character and meets the requirements, approval is almost guaranteed.

Through this citizenship, the family will have access to a safe environment, breathtaking scenery, plus the satisfaction of contributing to the development of a nation and environmentally friendly undertakings.
