Asia Research Hub: Greater China, Singapore, Hong Kong, India and Southeast Asia

An advisory reference for principals and family offices across Greater China, Singapore, Hong Kong, India, Japan, Korea and Southeast Asia examining São Tomé & Príncipe citizenship.

Last updated 10 August 2026 · Source: Citizenship by Investment Unit (CIU), Decree Law No. 07/2025

01 — Executive Summary

Investment migration in Asia

Asia is the largest source region for investment migration and the most internally varied. A Singaporean family office, an Indian promoter and a Hong Kong business owner face different nationality rules, capital-movement regimes and reporting duties, and examine a second citizenship for different reasons. This hub treats the region as a set of distinct legal environments rather than one market.

Three drivers recur. Mobility: several Asian passports remain constrained for business travel, and a second document reduces the administrative burden of short-notice trips. Succession: family businesses are passing to a new generation on an unprecedented scale, and inheritable status forms part of that planning. Jurisdictional balance: the reallocation of legal and personal footprint across more than one system.

Regulatory context governs everything else. India and China do not permit dual citizenship; Singapore does not permit it for adults; Hong Kong applies the Chinese Nationality Law with local specificities; Japan and Korea impose their own restrictions. In several of these jurisdictions, acquiring a foreign nationality has direct consequences for the existing one. That is the first question to resolve, not the last.

Within those constraints, the São Tomé & Príncipe Citizenship by Investment Programme is examined for its entry threshold, its remote process and the absence of any interview or language condition. It is administered by the Citizenship by Investment Unit (CIU) under Decree Law No. 07/2025, with a published review window of approximately 8 weeks.

02 — Applicant Profiles

Who typically applies

Family offices: Singapore and Hong Kong offices coordinating multi-jurisdictional structures for principals across the region.
Manufacturing and trading principals: Owners of export businesses in Greater China and Southeast Asia, for whom travel frequency is an operational cost.
Technology founders: Founders in India, Singapore and Southeast Asia planning expansion, listings or relocation.
Non-resident Indians and diaspora families: Households already outside their country of origin who want permanent status rather than a renewable permit.
Retirees and pre-retirees: Individuals planning cross-border retirement across Southeast Asia and beyond.
Global executives: Senior professionals in regional hub roles travelling frequently to Africa, Europe and the Americas.
Digital entrepreneurs: Location-independent operators valuing a document-based, fully remote application.

03 — Rationale

Why applicants choose São Tomé & Príncipe

Visa mobility as administrative relief: For holders of more constrained passports, a second document can reduce the frequency and complexity of visa applications. Verify specific access with the destination authority before travel.
Family inclusion: One application covers a spouse, financially dependent children under 30, and financially dependent parents and grandparents aged 55 and over — an unusually broad definition in a region where multi-generational households are the norm.
Tax considerations (high level): Most Asian jurisdictions tax on residence or source. A second citizenship does not alter residency; India, Singapore, Japan and Korea each apply their own tests and, in some cases, exit rules.
Wealth diversification: Regional family offices treat legal-status diversification as complementary to currency, custody and asset-class diversification.
Succession planning: A citizenship granted for life and inheritable by descendants aligns with the generational transfer underway across the region's family businesses.
Remote application: 100% remote application. No interview requirement. No language test.
Predictable, published costs: A single qualifying route from US$90,000, with government fees published in full rather than quoted case by case.

Note: this hub is a research resource. It does not constitute legal, tax or immigration advice, and readers should obtain qualified professional advice in their country of nationality and residence.

05 — Timeline

Typical applicant journey

Stage 1
Weeks 1–2
Engagement and preparation
An authorised agent is appointed, preliminary compliance screening is completed and the documentary file is assembled: identity and civil status records, police clearances and lawful source-of-funds evidence. Delay in investment migration originates here far more often than in government review. File quality at this stage largely determines the overall timeline.
Stage 2
Weeks 2–8
Submission and government review
The completed application is lodged with the Citizenship by Investment Unit (CIU). Review and Government Due Diligence run concurrently, not in sequence. Government Due Diligence is included within the Submission Fee — it is not charged as an additional fee.
Stage 3
Weeks 8–10
Approval in Principle and contribution
On a favourable decision, Approval in Principle is issued and the National Development Contribution (NDC) is remitted to the National Transformation Fund with any outstanding government fees. Dependants may be added after this point under a published post-approval schedule.
Stage 4
Weeks 10+
Registration and document issuance
Citizenship is registered and the passport, national identification card, citizenship certificate are produced and delivered. The entire process is conducted remotely — no travel to São Tomé is ever required.

The full stage-by-stage account is set out on the government process page.

06 — Regional Considerations

Matters specific to Asia

India: OCI and the single-nationality rule

India does not permit dual citizenship. Under the Citizenship Act, an Indian citizen who voluntarily acquires another nationality ceases to be Indian and must surrender the passport. Former nationals may in many cases apply for Overseas Citizen of India status — a lifelong visa and residence facility, not a citizenship.

The Liberalised Remittance Scheme also applies. It caps outward remittance per resident individual per financial year and requires funds to move through authorised dealer banks under the correct purpose code. Applications from India are often structured across financial years, or funded from money already held offshore. Indian legal and foreign-exchange advice should precede any remittance.

Greater China and Hong Kong

The Chinese Nationality Law does not recognise dual nationality: a Chinese national who voluntarily acquires a foreign nationality is treated as having lost Chinese nationality. Hong Kong applies the law with local administrative arrangements, and permanent residents there frequently hold foreign nationalities in practice, but the legal position should be confirmed with a qualified adviser.

Mainland rules cap individual foreign exchange purchases annually and bar their use for certain capital-account purposes. Applicants must be able to show a lawful and compliant funding route; agents cannot advise on circumventing these controls.

Singapore

Singapore does not permit dual citizenship for adults, and a Singaporean acquiring another nationality may be required to renounce one. Most Singapore-based applicants are therefore permanent residents or foreign nationals resident locally. The family office regime and the city's role as a booking centre make it the region's principal coordination point for these applications.

Japan, Korea and Southeast Asia

Under Article 11 of Japan's Nationality Act, a Japanese national who voluntarily acquires a foreign nationality loses Japanese nationality automatically; Article 14's election requirement applies to those who hold dual nationality from birth or by operation of law. Korea restricts dual nationality for adults. Southeast Asian rules range from broadly permissive to strictly single-nationality. Confirming the home-country position is the first step anywhere in this region.

Professional advice

This hub is a research resource, not legal, tax or foreign-exchange advice. Take advice in your country of nationality and residence before applying, particularly where dual nationality is restricted.

07 — Comparison

São Tomé & Príncipe in context

Investment migration programmes differ in legal effect, cost and timeline. The table below states published positions only; entry figures exclude government fees and professional costs unless indicated, and every programme is subject to change.

Programme	Type	Entry level	Indicative timeline	Notes
São Tomé & Príncipe — National Development Contribution (NDC)	CBI	US$90,000	~8 weeks	Single contribution route; remote application; CPLP member state; programme established 2025.
Vanuatu — Development Support Programme	CBI	From US$130,000	~1–3 months	Long-established Pacific programme; visa-free access to the EU/Schengen area was suspended for Vanuatu passport holders in 2024–2025.
St Kitts & Nevis — Sustainable Island State Contribution	CBI	From US$250,000	~4–6 months	Oldest CBI programme (1984); mandatory interview; higher entry threshold following the 2024 Caribbean price harmonisation.
Dominica / Antigua / Grenada	CBI	From US$200,000–US$235,000	~4–8 months	Caribbean contribution routes; Grenada holds a US E-2 treaty, the only Caribbean CBI to do so; all subject to EU visa-suspension review.
Malta — Citizenship by Naturalisation for Exceptional Services	Hybrid	From ~EUR 690,000 plus residence period	12–36 months	EU citizenship; ruled unlawful by the Court of Justice of the EU in April 2025 and consequently discontinued in its previous form.
Portugal — Golden Residence Permit	RBI	From EUR 250,000 (cultural donation) or EUR 500,000 (regulated funds)	18–36 months to residence	Residence, not citizenship; real-estate route closed in 2023; naturalisation requires a qualifying residence period and language attainment.

Regional consideration — Asia

One column carries disproportionate weight for Asian readers: whether the instrument is a nationality or a residence permit. For a national of a country that does not permit dual nationality, acquiring any of the CBI entries above raises a question under home law that a residence programme such as Portugal's does not. The distinction is legal rather than commercial, and should be resolved before cost or timeline is compared.

Detailed one-to-one analyses are published on the programme comparison pages.

08 — Government Process

How the government administers an application

Submission

Applications may only be lodged through an agent designated by the Citizenship by Investment Unit (CIU); there is no direct-to-government filing channel for private applicants. The submission fee of US$5,000 is payable per application and is non-refundable.

Government review and due diligence

Review is conducted by the Citizenship by Investment Unit (CIU) under Decree Law No. 07/2025. Government review and Government Due Diligence are conducted concurrently by the Citizenship by Investment Unit. Government Due Diligence is included within the Submission Fee — it is not charged as an additional fee. Screening typically encompasses identity verification, criminal-record checks, sanctions and politically-exposed-person screening, adverse media review and verification of the declared source of funds.

Decision and Approval in Principle

A decision is communicated to the agent, who notifies the applicant. Approval in Principle confirms that the government intends to grant citizenship subject to completion of the contribution and remaining fees. The published guidance measures approximately 8 weeks from formal submission of a complete application to government decision.

Contribution

The National Development Contribution (NDC) is remitted after Approval in Principle. Contribution levels are published by household composition, beginning at US$90,000 for a single applicant and rising in defined steps for couples and larger families, with US$5,000 for each additional dependant.

Registration and passport issuance

On receipt of the contribution, citizenship is registered and the document issuance fee of US$750 per applicant covers the passport, national identification card, citizenship certificate. The fee applies equally to adults, spouses, children and infants.

09 — Questions

Frequently asked questions — Asia

Can Indian citizens apply for São Tomé & Príncipe citizenship?+

They meet the programme's criteria, but India does not permit dual citizenship: voluntary acquisition of another nationality ends Indian citizenship and requires surrender of the passport. Former nationals may in many cases apply for OCI status. Independent Indian legal advice is essential.

What is OCI and is it the same as citizenship?+

Overseas Citizen of India status is a lifelong visa and residence facility for former Indian nationals and certain persons of Indian origin. It carries no voting rights and no Indian passport.

Can Chinese nationals hold dual citizenship?+

The Chinese Nationality Law does not recognise it. Voluntary acquisition of a foreign nationality is treated as loss of Chinese nationality; confirm your position with a qualified Chinese legal adviser.

Can Singapore citizens apply?+

Dual citizenship is not permitted for adults, so most Singapore-based applicants are permanent residents or foreign nationals resident in Singapore rather than citizens.

Are there limits on remitting funds from India?+

The Liberalised Remittance Scheme caps outward remittance per resident individual per financial year and requires transfer through authorised dealer banks under the correct purpose code. Take Indian foreign-exchange advice before remitting.

Can Hong Kong residents apply?+

Yes, subject to the individual's nationality position. Hong Kong applies the Chinese Nationality Law with local administrative arrangements, so qualified advice is warranted.

Can Japanese or Korean nationals apply?+

Under Article 11 of Japan's Nationality Act, a Japanese national who voluntarily acquires a foreign nationality loses Japanese nationality; Article 14 sets a separate election obligation for those holding dual nationality from birth or by operation of law. Korea restricts dual nationality for adults. Confirm the position with a qualified adviser at home before applying.

Can multi-generational households apply together?+

Yes. One application can include a spouse, financially dependent children under 30, and financially dependent parents and grandparents aged 55 and over.

Can Asian nationals obtain São Tomé & Príncipe citizenship by investment?+

Yes. Open to applicants of all nationalities except the Democratic People's Republic of Korea. The statutory criteria — age 18 or over, clean criminal record, verifiable lawful source of funds — apply identically across the region. The constraint that varies is not eligibility here but the applicant's own nationality law at home.

How much does the programme cost?+

Contributions begin at US$90,000 for a single applicant. With government fees added, the indicative all-in figure is US$100,750 for one applicant and US$108,000 for a family of four.

How long does approval take?+

Approximately 8 weeks from formal submission of a complete application to government decision. Review and due diligence run concurrently, which is why the window is shorter than in most comparable programmes.

Is there a residency or physical presence requirement?+

None. No travel to São Tomé & Príncipe is required at any stage.

Can the whole application be completed remotely?+

Yes — from engagement to document delivery. The entire process is conducted remotely — no travel to São Tomé is ever required.

Can a spouse be included?+

A spouse or de facto partner may be included in the main application, or added later under a published post-approval fee.

Can children be included?+

Children under 30 qualify where they are financially dependent on the main applicant. Newborns may be added up to one year of age after approval.

Can parents or grandparents be included?+

Yes, where they are aged 55 or over and financially dependent on the main applicant.

What documents are required?+

A complete file generally comprises: valid passport copy; birth certificate; police clearance certificate; proof of address; source of funds evidence; passport-style photographs; marriage certificate (where applicable). Legalisation routes differ across the region: India, China, Japan, South Korea and Singapore are party to the Hague Apostille Convention, so an apostille is issued by the designated competent authority in each; states outside it require consular legalisation. Non-Latin-script records need certified translation.

What documents does a successful applicant receive?+

Passport, National Identification Card, Citizenship Certificate. The issuance fee of US$750 per applicant covers all three, and applies equally to adults, spouses, children and infants.

Is there a separate due diligence fee?+

Government Due Diligence is included within the Submission Fee — it is not charged as an additional fee.

Is an interview required?+

No interview is held at any stage, and no language test is set.

Is a language test or education qualification required?+

Neither. No business experience requirement.

Does São Tomé & Príncipe permit dual citizenship?+

Dual citizenship is fully recognised. Asia is not one jurisdiction on this point, and the differences are decisive. India and China do not permit dual nationality; Singapore, Japan and South Korea each restrict it, subject to their own statutory exceptions and procedures. Whether an existing nationality survives the acquisition of another is determined solely by the law of that country, and requires advice from counsel qualified there before any application is filed.

Is the citizenship permanent and can it be passed to children?+

Citizenship is granted for life and is inheritable by descendants.

Which authority administers the programme?+

The Citizenship by Investment Unit (CIU), under Decree Law No. 07/2025. Contributions are made to the National Transformation Fund.

Can an application be filed directly with the government?+

No. Filing runs through agents designated by the CIU; there is no direct channel for private applicants.

What happens if an application is declined?+

The submission fee of US$5,000 per application is non-refundable and covers Government Due Diligence. The contribution falls due only after Approval in Principle.

Are there nationality restrictions?+

Open to applicants of all nationalities except the Democratic People's Republic of Korea.

Does São Tomé & Príncipe citizenship confer visa-free travel rights automatically?+

Visa policy is set unilaterally by each destination and changes over time. No passport should be acquired on a mobility figure alone; verify current entry requirements for the destinations that matter to you, at the time you travel.

Is São Tomé & Príncipe a member of the CPLP?+

Yes. The Community of Portuguese Language Countries has nine member states: Portugal, Brazil, Angola, Mozambique, Cabo Verde, Guinea-Bissau, Equatorial Guinea, Timor-Leste and São Tomé & Príncipe. Guinea-Bissau's membership was suspended in December 2025. Membership frames cooperation between states; it confers no automatic residence rights on individuals.

Does acquiring citizenship change where a person pays tax?+

Not by itself. Liability generally follows tax residency and, in a few countries, domicile or citizenship-based rules. Take qualified tax advice at home before applying.

10 — Research Resources

Investment migration terminology

Citizenship by Investment (CBI): A statutory pathway under which a sovereign state grants citizenship in return for a qualifying economic contribution, subject to due diligence and legislative conditions.
Residence by Investment (RBI): A pathway granting residence rights — not citizenship — in return for investment. Naturalisation, where available, generally requires years of physical presence.
National Development Contribution (NDC): The qualifying route of the São Tomé & Príncipe Citizenship by Investment Programme: a non-refundable contribution to the National Transformation Fund.
Approval in Principle (AIP): A government decision confirming intent to grant citizenship, conditional on completing the contribution and outstanding fees.
Government Due Diligence: The state's independent vetting of an applicant. In this programme it is conducted concurrently with review and is included within the submission fee.
Source of funds: Documented evidence of how the applicant's wealth used for the application was lawfully generated — employment, business proceeds, investment gains, inheritance or sale of assets.
Source of wealth: The broader documented history of how an applicant's total net worth was accumulated, distinct from the specific funds used for an application.
Politically Exposed Person (PEP): An individual entrusted with a prominent public function, or their close associate or family member, subject to enhanced scrutiny under international AML standards.
Dependant: A family member included in an application. Here: a spouse or de facto partner, financially dependent children under 30, and financially dependent parents and grandparents aged 55 and over.
Dual citizenship: The simultaneous holding of two or more nationalities. Whether a person may retain their existing nationality is determined by that country's law, not by São Tomé & Príncipe.
CPLP: The Community of Portuguese Language Countries — an intergovernmental organisation of Lusophone states including Portugal, Brazil, Angola, Mozambique and São Tomé & Príncipe.
Visa-free access: Entry to a destination without a pre-issued visa. Access is set unilaterally by each destination and can change; it is never guaranteed by a passport alone.
Tax residency: The jurisdiction entitled to tax a person's income, determined by domestic law tests such as presence, domicile or centre of vital interests. Citizenship and tax residency are distinct concepts.
CRS: The OECD Common Reporting Standard for the automatic exchange of financial account information between participating jurisdictions. Reporting follows tax residency, not passport-holding.
Designated agent: A firm authorised by the Citizenship by Investment Unit (CIU) to prepare and submit applications. Private applicants cannot file directly.
