São Tomé and Príncipe Citizenship by Investment

São Tomé and Príncipe citizenship by investment is the world’s newest CBI programme, officially launched on 01/08/2025 with a minimum contribution of just $90,000 USD for an individual — significantly lower than Vanuatu ($130,000 USD) and the Caribbean programmes ($200,000 USD). This article analyses the legal framework, cost structure and review process, together with the strengths and risks of this new programme, from the perspective of Vietnamese investors.

Overview of São Tomé and Príncipe and the programme’s legal framework

São Tomé and Príncipe is a small island nation in Central Africa, located in the Gulf of Guinea with a population of about 240,000. The official language is Portuguese, a legacy of the colonial period that lasted until 1975. The country’s economy is based mainly on agriculture (especially cocoa), fishing and eco-tourism.

The country’s citizenship by investment programme is governed by two main legal instruments:

• Nationality Law No. 07/2022 of 10/03/2022 (Lei da Nacionalidade)
• Decree-Law No. 07/2025 of 01/08/2025 (Decreto-Lei n.º 07/2025 – Regulamentação da Nacionalidade por Investimento ou Doação)

Decree-Law 07/2025 was published in Diário da República No. 33 on 01/08/2025 and provides the official legal basis for the programme. This is the core difference between the current programme and the rumours of a “São Tomé CBI” that circulated on the market before 2025 — which had no legal basis.

The programme is administered by the Citizenship by Investment and Donation Unit (Unidade de Cidadania por Investimento e Doação – UCID), also known asCitizenship Investment Unit (CIU)in English-language documents. The unit operates on a public-private partnership model, with a technical office in Dubai.

Investment options and cost structure

The programme currently has only one investment option: a non-refundable contribution to the National Transformation Fund (Fundo Nacional de Transformação – FNT). This differs from many other CBI programmes, which offer real estate or government bond options alongside.

The contribution structure is as follows:

• Main applicant: $90,000 USD
• Family of up to 4 people (spouse + dependent children): $95,000 USD in total
• Dependants added after initial approval: $10,000 USD for a spouse, $5,000 USD for other dependants, $500 USD for a newborn

Besides the main contribution, applicants must pay mandatory fees:

• One-time application fee: $5,000 USD per application (non-refundable)
• Citizenship document fees (certificate, passport, ID card): $750 USD per person
• Government due diligence fee
• Authorised agent service fees

The actual total cost for an individual usually ranges from $100,000 to $110,000 USD once all fees are added — still significantly lower than other CBI programmes worldwide.

The National Transformation Fund and how it is used

The National Transformation Fund (FNT) was established together with the programme to manage and use investors’ contributions for national priority development projects. Under Decree-Law 07/2025, the funded sectors include:

• Renewable energy
• Sustainable development and environmental protection
• Eco-tourism infrastructure
• Agriculture and food security
• The education system
• Basic transport infrastructure

The fund model is similar to the National Development Fund (NDF) of Caribbean countries such as Antigua and Barbuda, or the Sugar Industry Diversification Foundation (SIDF) formerly used in Saint Kitts and Nevis. Transparency in how the fund is disbursed will be key to the programme keeping its reputation in the long term.

Eligibility and applicant requirements

The basic eligibility conditions for São Tomé and Príncipe citizenship by investment are:

• The main applicant must be 18 or over
• No criminal record and not on any international wanted list
• Health meeting UCID requirements
• Lawful and traceable investment funds
• Passing the multi-layered security due diligence carried out by UCID in coordination with international intelligence agencies
• Providing all required legal documents

The programme is open to citizens of all countries except North Korea (the DPRK). Notably, it also accepts Russian and Iranian citizens, de facto partners and stateless people — more flexible than many other CBI programmes that apply nationality restrictions.

Dependants who may be included in the application:

• Legal spouse
• Dependent children under 30
• Parents aged 55 or over
• Dependent grandchildren

All dependants aged 16 and over must undergo their own security due diligence. The programme has no physical residence, interview or language requirements.

The São Tomé and Príncipe citizenship by investment process and processing times

The São Tomé and Príncipe naturalisation review follows an “approval-first” model — applicants pay the main contribution only after receiving Approval in Principle. This is a financial safeguard similar to that of Vanuatu and modern Caribbean programmes.

The basic steps:

1. Initial consultation and choice of an Authorized Agent
2. Preparing the file and submitting it to UCID through the agent
3. Paying the $5,000 USD application fee and the due diligence fee
4. UCID carries out multi-layered security due diligence
5. Receiving Approval in Principle (6 weeks on average)
6. Paying the $90,000 USD contribution to the FNT
7. Receiving the certificate of citizenship and passport

The officially published processing time is 60–90 days from submission of a complete application. According to UCID, the first 27 applications were approved and the first passports issued in January 2026. The entire process can be completed remotely, without applicants having to travel to São Tomé and Príncipe.

Strength of the São Tomé and Príncipe passport

This is the most important point to note when assessing the programme. The São Tomé and Príncipe passport currently gives visa-free, visa-on-arrival or eVisa access to about 60–63 countries and territories — significantly fewer than the Vanuatu passport (~90 countries) and Caribbean passports (130–150 countries).

Check thestrength of the São Tomé and Príncipe passport.

Notable visa-free or visa-on-arrival destinations:

• Singapore: 30 days visa-free
• Hong Kong: visa-free
• Russia: visa-free
• Most African countries
• Some Central American and Caribbean countries

The biggest limitation: the São Tomé and Príncipe passport does not give visa-free access to the Schengen Area, the United Kingdom or the United States. For investors who need to travel globally on a regular basis, this is a major barrier to consider.

Adult passports are valid for 7 years, and passports for children under 16 for 3 years. Renewals can be done at a São Tomé and Príncipe embassy or directly at the UCID office in Dubai.

Comparison with other CBI programmes

São Tomé and Príncipe citizenship by investment holds a special position in the global CBI market thanks to having the lowest cost. However, each programme has its own advantages suited to different goals.

Compared with the alternative programmes:

• Dominica Citizenship by Investment: minimum $200,000 USD, passport with Schengen access, 30+ years of reputation
• Saint Kitts and Nevis Citizenship by Investment: minimum $250,000 USD, a strong passport, the oldest programme in the world
• Saint Lucia Citizenship by Investment: minimum $240,000 USD, passport with Schengen + UK access
• Antigua and Barbuda Citizenship by Investment: minimum $230,000 USD, passport with Schengen + UK + Canada access
• Grenada Citizenship by Investment: minimum $235,000 USD, passport with Schengen access + the US E-2 visa
• Nauru Citizenship by Investment: minimum $105,000 USD, a new programme launched in 2024

São Tomé and Príncipe suits investors on a limited budget who only need a “second citizenship” as a legal backup and do not require strong mobility. For those who prioritise international mobility, the Caribbean programmes remain the superior choice.

Risk assessment and points to note

As a newly launched programme, the São Tomé and Príncipe CBI carries some risks investors should weigh before deciding.

Main risks:

• The programme is very new (less than 1 year in operation) and has no long-term track record
• Western countries may impose visa restrictions similar to those applied to Vanuatu in 2022
• International banks may require additional due diligence on São Tomé and Príncipe passport holders
• Implementation is still being refined, and the operating guidelines may be adjusted
• UCID’s final decisions are political in nature and not purely technical

Positive points to note:

• A clear legal basis through Decree-Law 07/2025, published in the official gazette
• The lowest cost in the global CBI market
• A transparent process, with payment after approval
• Unrestricted dual citizenship allowed
• The public-private partnership model brings international management expertise through the Dubai office

Anyone claiming to be an official agent should be verified against UCID’s published list. Under the programme’s rules, only authorised agents can submit applications — applications submitted through unauthorised intermediaries will be rejected immediately.

Summary

The 2026 São Tomé and Príncipe CBI programme marks the arrival of the world’s lowest-cost CBI programme, with a clear legal framework backed by Decree-Law 07/2025. The $90,000 USD contribution and 60–90 day processing time make it an attractive option for investors on a limited budget or who need a backup plan.

However, its biggest weakness is passport strength — with only about 60 visa-free destinations and no Schengen access — making the programme unsuitable for investors who need to travel globally on a regular basis. The choice between São Tomé and Príncipe and the Caribbean programmes should be based on each investor’s specific goal: the lowest cost, global mobility, or a long-term legal plan B.
