Due Diligence in Citizenship by Investment: What Governments Check

The Purpose of Due Diligence

Citizenship by investment programmes are attractive to investors, but they are also attractive to individuals who should not have access to them: those seeking to escape accountability for past crimes, to launder money through a sovereign wealth vehicle, to circumvent international sanctions, or to acquire a neutral travel document to move freely despite being subject to restrictions in their home country.

Governments running CBI programmes need to ensure that the citizenship they grant does not become a reputational liability — for themselves, for the integrity of their passport's visa-free relationships, and for their international standing. The EU, the US, the UK, and other major jurisdictions monitor CBI programme standards closely and can revoke visa-free access if they conclude a programme's due diligence is inadequate. (Vanuatu experienced exactly this with the EU in 2022.)

Due diligence is therefore not merely a bureaucratic exercise. It is the mechanism by which a programme maintains its own value — and the primary reason why passports from programmes with strong due diligence records (such as St Kitts and Nevis) command higher market credibility than those from programmes with weaker processes. (Malta long set the benchmark for rigorous investor-citizenship due diligence, but its citizenship-by-investment programme was withdrawn in 2025 following a Court of Justice of the EU ruling.)

What Due Diligence Actually Checks

Criminal Record Screening

Every CBI programme checks applicants against criminal records databases. This includes:

• National criminal records in the applicant's country of citizenship
• Criminal records in all countries of prior residence (hence the requirement for police clearances from each country)
• International criminal databases including Interpol wanted notices (Red Notices)
• Sanctions lists including: UN Security Council sanctions, EU sanctions, US OFAC sanctions, UK financial sanctions
• Court records in relevant jurisdictions, which can reveal civil proceedings as well as criminal ones (particularly important for matters such as fraud allegations, bankruptcy, or asset freezes that may not appear on a criminal record per se)

Disqualifying criminal history typically includes:

• Any conviction for financial crime (fraud, money laundering, embezzlement, bribery, corruption, tax evasion)
• Drug trafficking or serious drug-related offences
• Violent crime, offences against persons, sexual offences
• Terrorism-related offences or material support for terrorism
• Convictions involving organised crime connections
• Prior sanctions violations

Non-disqualifying matters (in most programmes) typically include:

• Minor motoring offences (minor speeding, parking)
• Spent minor convictions from many years ago
• Civil litigation that did not result in adverse judgements
• Tax disputes that were settled without findings of evasion

The key word is "typically". Individual programme rules differ. An adviser who has seen a wide range of applications is the best source of case-specific guidance.

Source of Wealth and Funds

This is where due diligence extends beyond the criminal record into financial analysis. The key questions are:

Source of specific funds: Where did the money being invested come from? Is it in an account in the applicant's name? Can the journey of those funds be traced from their origin (business income, salary, property sale) to the current account?

Source of overall wealth: How did the applicant become as wealthy as they are? Does the overall wealth picture make sense given their stated career and business history? Are there unexplained accumulations that do not correlate with legitimate income sources?

Tax compliance: Has the applicant's income been properly declared to relevant tax authorities? Are there outstanding tax liabilities or tax investigations?

Business connections: Are there business relationships with sanctioned individuals, entities in sanctioned jurisdictions, or entities with reputational concerns? Especially relevant for investors from Russia, Iran, North Korea, Belarus, Venezuela, and other sanctioned territories.

Due diligence firms conduct this analysis using:

• World-Check and equivalent databases (aggregated PEP and adverse media information)
• Company registry searches in relevant countries
• Court filing database searches
• Media archive searches in multiple languages and jurisdictions
• In some cases, local enquiries through in-country research networks

PEP Status

A politically exposed person (PEP) is defined differently across different frameworks, but generally includes:

• Heads of state and government; senior government ministers; senior civil servants
• Senior military officials
• Senior executives of state-owned enterprises
• Senior officials of international organisations
• Members of parliament and equivalents
• Senior judicial officials
• Close family members of all of the above (typically: spouse or partner, children, parents, siblings)
• Known close associates of all of the above

PEP status is not a disqualification, but it is a trigger for enhanced due diligence. An individual who is a PEP — or who has a PEP as a family member — will face significantly more detailed scrutiny of their source of wealth. The underlying logic is that individuals in positions of public power have access to corrupt enrichment, and wealth whose origins cannot be convincingly explained raises questions about whether it derives from that position.

For PEP applicants, the due diligence file needs to be substantially more detailed:

• Comprehensive career history and evidence of income over time
• Evidence that official positions held were compensated at appropriate rates
• Explanation of any business interests held alongside public positions and how conflicts of interest were managed
• For family members: evidence that their wealth is independently sourced and does not derive from the relative's public position

Many experienced advisers conduct a "shadow due diligence" exercise for PEP applicants — essentially doing the due diligence firm's work in advance, to identify anything that might be flagged and prepare appropriate documentation and explanations. This significantly reduces the risk of an RFI or adverse recommendation.

The Multi-Tier Process

Malta: The Historical Benchmark (Programme Now Withdrawn)

Malta long ran the most rigorous due diligence process of any investor-citizenship programme. Its scheme was ruled unlawful by the Court of Justice of the EU on 29 April 2025 and has since been withdrawn, so it is no longer an available route — but its four-tier model remains the standard reference point for how thorough investor-citizenship due diligence can be:

• Tier 1 — Authorised Agent Due Diligence: The agent (the licensed Maltese firm through which the application is submitted) conducts its own background check and confirms it has done so to the programme authority.
• Tier 2 — Agency Review: Malta's Community Malta Agency (which had replaced the earlier Individual Investor Programme Agency) reviewed the full application file.
• Tier 3 — Independent Due Diligence: Two independent, internationally recognised due diligence firms conducted concurrent background investigations on each applicant. Both reports had to be satisfactory.
• Tier 4 — Ministerial/Cabinet Approval: Final approval at the political level.

Caribbean Programmes: Typically Three Tiers

The Caribbean CBI programmes (St Kitts, Dominica, Grenada, Antigua, St Lucia) generally run a three-tier process:

• Tier 1 — Agent Review: The authorised agent reviews the file and confirms due diligence compliance
• Tier 2 — Programme Authority Review: The Citizenship by Investment Unit in the relevant country reviews the full application
• Tier 3 — Independent International Due Diligence: At least one (often two) internationally contracted firms conduct background investigations

St Kitts is consistently regarded as running the most rigorous Caribbean due diligence, in part because it has operated the longest and has the most to lose from a reputational failure.

Vanuatu: Streamlined

Vanuatu's faster processing correlates with a less extensive due diligence process. This was the EU's concern in 2022, and it is worth noting for applicants who are considering the Vanuatu route.

How to Prepare a Clean Due Diligence File

The goal is not to hide anything — which is both unethical and counterproductive — but to present the complete, accurate picture in the most clearly documented form, so that due diligence reviewers can efficiently verify everything and have no need to flag concerns or request additional information.

Principles:

1. Disclose everything relevant. Undisclosed matters are treated as integrity failures. Even if a criminal conviction is minor and spent, disclose it and provide context. Even if a business dispute was settled without findings, disclose it. Reviewers will often find these things anyway; not disclosing them is far worse than the underlying matter.

2. Build a coherent wealth narrative. The source-of-funds and source-of-wealth documentation should tell a complete, coherent story from the beginning of your career to the present. Each stage should be documented: early employment income, business growth, investment returns, property sales, inheritance — whatever applies. Gaps in the narrative invite questions.

3. Explain unusual features proactively. If there is something in your history that looks unusual out of context — a large receipt of funds, a business in a complex jurisdiction, a period of unusual income — address it proactively in a covering letter or statutory declaration rather than leaving reviewers to draw their own conclusions.

4. Quality of documentation. Source documents (bank statements, tax returns, company accounts) should be originals or certified copies, clearly legible, complete (not missing pages), and in English or with certified translations.

5. Pre-screen before committing. A professional pre-clearance review by an experienced adviser before the full application is submitted identifies potential issues early, when they can be addressed without cost.

What Causes Rejection

The most common rejection grounds, in order of frequency:

1. Undisclosed criminal conviction or civil matter
2. Unsatisfactory source-of-wealth explanation (unexplained wealth)
3. PEP status with insufficient wealth documentation
4. Adverse media findings (e.g., journalism that reported fraud allegations, even if never prosecuted)
5. Business connections to sanctioned individuals or entities
6. Prior rejection in another CBI/RBI programme (must be disclosed; failure to disclose is itself a rejection ground)
7. Sanctions list inclusion of the applicant or a family member
8. Incomplete documentation after repeated requests for information
