CBI due diligence fees explained: what you're actually paying for in 2026

Last updated: April 2026

You've done the math on minimum investments, government fees, and agent retainers. Then someone mentions due diligence fees — and suddenly there's another $12,000 to $15,000 line item on the spreadsheet you didn't fully account for.

Due diligence fees are the most misunderstood cost category in citizenship by investment (CBI) programs. Most guides lump them into a single number. Fewer explain what actually happens during the process, why costs increased in late 2025, and what determines whether an application passes or gets flagged.

This guide breaks down exactly what CBI due diligence covers, what each Caribbean program charges in 2026, how the ECCIRA reforms that took effect in December 2025 changed the process — and what applicants typically overlook until it costs them time and money.

Note: Due diligence rules and fee structures are reviewed periodically by Caribbean program units. Figures in this guide reflect 2026 rates as of April 2026. Always verify current fees directly with the program authority or your authorized agent before submitting.

Key takeaways

• CBI due diligence fees operate on two layers: government-administered background checks (paid to the program unit) and agent-managed document preparation and coordination (included in or billed alongside agent fees).
• 2026 fee ranges: Grenada and Antigua are the most expensive at roughly $14,000–$15,000 for a main applicant plus spouse. Dominica and St. Kitts sit in the $12,000–$12,500 range.
• ECCIRA (December 2025) introduced mandatory biometric enrollment and in-person interviews for all adult applicants, adding $1,500–$2,000 per person and 4–8 weeks to timelines.
• Rejection from one Caribbean program now flags all four under the shared ECCIRA database. If you've been declined elsewhere, disclose it proactively — it will surface.
• Pre-screening before submission is the most cost-effective use of agent fees. Catching problems before they reach the program unit saves far more than it costs.

What due diligence actually is in a CBI context

"Due diligence" in CBI programs refers to the background vetting process that every applicant undergoes before an application is approved. The program authority — Grenada's Citizenship by Investment Unit, St. Kitts' CIU, and so on — is legally responsible for verifying that applicants meet the character and integrity requirements of the program.

This is not a formality. Caribbean programs have faced significant international scrutiny over the past decade for approving applicants who later appeared in sanctions lists, criminal proceedings, or tax fraud investigations. ECCIRA (the Eastern Caribbean Citizenship by Investment Regulatory Authority), which launched its enhanced framework in December 2025, represents the region's most serious structural response to that pressure.

Due diligence operates at three tiers:

Tier 1: Basic background check

Every applicant undergoes a foundational criminal and financial check. This typically includes:

• National criminal record verification from all countries of citizenship and long-term residence
• Interpol database cross-reference
• Basic financial history review
• Sanctions list screening (OFAC, EU, UN)

This tier is included in every CBI government fee structure. It forms the floor, not the ceiling, of what program units actually review.

Tier 2: Enhanced due diligence

For applicants flagged in Tier 1 — or for those from jurisdictions where official records are less reliable — programs escalate to enhanced screening:

• Adverse media search (news archives, court records, regulatory filings across multiple languages)
• PEP (politically exposed person) screening and relationship mapping
• Beneficial ownership verification for business interests
• Second-level source of funds review

Enhanced due diligence is not always disclosed as a separate fee. Some programs fold it into the base government DD fee; others charge a supplemental amount when escalation occurs. If you are a PEP, have complex business ownership, or come from a higher-scrutiny jurisdiction, budget for it.

Tier 3: Interview and biometrics (post-ECCIRA, December 2025)

This is the most significant structural change to CBI due diligence in a decade.

As of December 2025, all four Eastern Caribbean CBI programs — Grenada, St. Kitts & Nevis, Antigua & Barbuda, and Dominica — require:

• In-person or video interview for all adult applicants (18+)
• Biometric enrollment: fingerprints and facial recognition data submitted to the ECCIRA shared database
• Extended source of funds documentation: bank statements and financial records going back five to seven years

The interview requirement is new. Previously, due diligence was largely a document-based process. The biometric database means that data from one program is now visible to the others — a meaningful change in how rejections propagate across the Caribbean CBI landscape.

2026 due diligence fee ranges by program

The figures below reflect government-published due diligence fees. Agent fees for document management, interview preparation, and coordination are separate and covered in the next section.

Combined main applicant + spouse approximate totals:

• Grenada: ~$15,000
• St. Kitts & Nevis: ~$12,500 (main applicant; spouse and family rates quoted separately)
• Antigua & Barbuda: ~$14,000 (family of four included in base; additional dependents over four at ~$3,000 each)
• Dominica: ~$12,000

A few notes on these figures:

Grenada's fees sit at the high end, but the program's CARICOM integration and E-2 treaty eligibility make it attractive for specific applicant profiles — the DD cost is part of a larger value calculation.

St. Kitts has historically been one of the most rigorous programs. The per-dependent adult fee is non-trivial for applicants adding multiple family members.

Dominica remains the most cost-accessible option at the DD level, though ECCIRA requirements now apply equally across all four programs.

How ECCIRA changed due diligence (December 2025)

ECCIRA's December 2025 framework update introduced three structural changes that every applicant needs to understand going into 2026.

Shared biometric database

The four participating programs — Grenada, St. Kitts, Antigua, and Dominica — now share biometric records and application outcomes. This means:

• A rejection or withdrawal from any one program is visible to the others
• Biometric data submitted to one program is enrolled in the shared database at submission
• The system is designed to prevent applicants from shopping programs after a refusal

The practical implication: if you were declined by one Caribbean program in 2024 or 2025 and did not disclose it in a new application, the database will surface it. Non-disclosure of prior rejections is treated as a material integrity failure — grounds for immediate refusal, not just re-review.

Mandatory interview requirement

Previously, the CBI application process was largely paper-based. Program units reviewed documents and commissioned background checks, but most applicants never spoke to a program officer.

That changed in December 2025. All adult applicants must now complete a structured interview — either in person at a designated interview center or via video with a certified officer. The interview covers:

• Source of funds and wealth narrative
• Business activities and professional background
• Purpose of citizenship acquisition
• Family member relationships (for dependents included in the application)

Cost: $1,500–$2,000 per adult applicant. This fee is charged per person and is not waivable.

Timeline impact: 4–8 weeks additional. Interview slots at regional centers are in high demand following the December 2025 rollout. Some agents are reporting waits of six to eight weeks for interview scheduling, particularly in Q1 and Q2 2026.

Extended documentation requirements

The ECCIRA framework extended the required lookback period for financial documentation from three years to five to seven years. This means:

• Bank statements: five to seven years depending on program
• Source of funds evidence: full chain of wealth origin, not just current account balances
• Utility bills and proof of address: going back at least three years for all addresses
• Business ownership documentation: full beneficial ownership maps for any company in which the applicant holds a meaningful interest

For applicants with complex business structures, multiple jurisdictions of residence, or significant investment portfolios, the documentation burden is substantial.

What agents charge for due diligence management

Government DD fees are fixed by the program unit. What varies is the agent layer — the services an authorized agent provides to prepare, compile, and coordinate an application through the due diligence process.

These are the typical categories and approximate fee ranges:

Pre-screening

$2,000–$5,000

This is the stage that matters most and is most frequently skipped by applicants trying to minimize upfront costs.

Pre-screening involves the agent reviewing an applicant's background before any submission to the program unit. The objective is to identify potential issues — prior criminal matters, PEP connections, inconsistent source of funds narratives, prior rejections — before they surface during formal review.

A good pre-screening catches problems while they are still solvable. Document gaps can be addressed. A prior criminal matter — even a minor one — can be disclosed correctly and contextualized rather than discovered and treated as concealment.

Skipping pre-screening to save a few thousand dollars is a category error. The cost of a failed application — lost government fees, wasted time, and a rejection now visible in the ECCIRA database — far exceeds the pre-screening cost.

Document preparation

$3,000–$8,000

CBI applications involve substantial document compilation: notarized copies, apostilles, certified translations, bank reference letters, professional letters of recommendation, police clearance certificates from all relevant jurisdictions, and the extended financial documentation now required under ECCIRA.

Agent fees at this stage cover document review for completeness and compliance, coordination with notaries and apostille authorities, managing translations, and ensuring format compliance with specific program requirements. Each program has its own specification standards. A document accepted by Grenada's CIU may require reformatting for Dominica's.

For applicants with a Turkish background, this step includes coordinating apostille certification through the Turkish Ministry of Foreign Affairs, which has its own processing windows. More on this below.

Interview preparation

$1,500–$3,000

Given that interviews are new to the Caribbean CBI process, thorough preparation has become a meaningful service. Agents — particularly those with direct experience from the post-December 2025 cohort — can provide:

• Mock interview sessions covering likely questions
• Wealth narrative structuring (how to explain source of funds clearly and consistently)
• Document review specific to interview presentation
• Coordination with interview centers for scheduling

Ongoing coordination

This is typically included in the overall agent service fee rather than billed separately. It covers communication with the program unit during the review period, responding to requests for additional information, and managing any escalations.

What triggers a red flag — and why it matters more now

Under the ECCIRA shared database, a rejection does not stay with one program. It follows the applicant across all four. Understanding what triggers scrutiny is worth more than any other section of this guide.

Criminal history

Any conviction — not exclusively felonies, and including matters that may have been expunged in the home country — is subject to disclosure. Programs assess criminal matters against a materiality standard, but non-disclosure is treated more seriously than the underlying matter in many cases. If you have any conviction in your history, disclose it and let your agent manage the narrative.

PEP status

A politically exposed person designation applies not just to current officeholders but to former officials, their immediate family members, and close business associates. The definition is broad. If you held a government position, worked closely with elected officials, or have family members who did, your application will receive enhanced scrutiny regardless of the circumstances.

PEP status does not automatically disqualify an applicant. Undisclosed PEP status typically does.

Inconsistent source of funds documentation

The most common technical failure in CBI applications is a gap between declared wealth and documented wealth. If an applicant states that funds come from a business sale but cannot produce the transaction records, or declares rental income that does not appear in tax filings, the application is flagged.

The extended ECCIRA documentation lookback has made this a sharper issue. Wealth generated before the lookback period and not adequately traced creates documentation gaps that agents need to address proactively.

Connections to sanctioned jurisdictions or individuals

Business relationships with entities in sanctioned jurisdictions — even indirect ones through corporate structures — will surface in an enhanced background check. This is particularly relevant for applicants with trade or investment exposure to Russia, Belarus, Iran, North Korea, or Myanmar.

Prior rejections

As noted, the ECCIRA database now surfaces prior Caribbean program rejections at submission. Any rejection — even one from several years ago — should be disclosed upfront to your agent. How a prior rejection is handled (disclosed correctly, with context) is materially different from how it is treated when discovered mid-process.

The typical due diligence timeline

A realistic timeline from submission through DD clearance in 2026:

Pre-ECCIRA, a straightforward Caribbean CBI application could complete the full process in three to four months. The interview scheduling bottleneck in 2026 is adding material time to even clean, uncomplicated applications.

What's typically included vs. what costs extra

Who this is NOT for

Due diligence fees are not the primary issue if you are in one of the following situations.

If you have a serious undisclosed criminal history, the due diligence process will surface it. No agent can alter what the background check finds. The question is whether the matter is disclosed correctly before it surfaces — which changes how it is handled — not whether the DD fees are structured optimally.

If you have been rejected from a Caribbean CBI program without disclosing it, submitting to another program in 2026 without addressing this upfront is likely to result in another rejection. The ECCIRA database changes the calculus entirely.

If you are a high-profile PEP and have not engaged an advisor who specifically handles PEP applications, a standard authorized agent may not be the right resource. Complex PEP applications require advisors with direct regulatory relationships and experience managing enhanced scrutiny processes.

If you are purely focused on minimizing upfront costs, understand that cutting corners on pre-screening and document preparation is where rejections and delays originate. The due diligence phase is not the place to optimize for the lowest possible fee.

Two applicants who got this wrong — and right

The case of incomplete source of funds documentation

A founder with a complex business structure — a holding company in Cyprus, an operating subsidiary, and multiple historical transactions — submitted his Grenada application with three years of bank statements and a summary of business value. The DD review flagged an inconsistency: a significant capital event appeared in his current account balance but wasn't traceable in the provided documentation.

The application was suspended, not rejected. His agent requested an additional eight weeks to compile the full transaction chain going back five years. The application eventually cleared, but the delay cost him the scheduled interview slot and pushed his approval date back by three months.

Had his agent conducted proper pre-screening, the documentation gap would have been identified before submission. The cost of pre-screening — roughly $3,000 — would have saved $8,000 in extended coordination fees and months of timeline.

The applicant who disclosed everything

A retired Turkish civil servant with a local government role in her background engaged an agent who flagged her PEP status at pre-screening. Rather than treating it as disqualifying, the agent structured her wealth narrative clearly, obtained formal documentation confirming the nature and conclusion of her public role, and submitted the application with a cover letter contextualizing her status.

Her application cleared enhanced DD in six weeks. The enhanced scrutiny was expected — but disclosure and preparation meant it was handled as a process, not a surprise.

Preparing for your CBI due diligence: a practical document checklist

Documents typically required for due diligence in all four Caribbean programs:

• Valid passport (all passports held, not just the one in active use)
• National identity document(s)
• Birth certificate
• Marriage certificate (if applicable), divorce decree if relevant
• Police clearance certificates from all countries of citizenship and residence for the past ten years
• Proof of address: utility bills or bank statements (three years, multiple addresses as applicable)
• Bank statements: five to seven years under ECCIRA requirements
• Source of funds documentation: transaction records, property sale agreements, investment statements, business valuation reports
• Employer letters or business ownership certificates
• Professional references (two to three, typically from lawyers, accountants, or senior business contacts)
• Certified translations of all non-English documents
• Apostilles where required by program specifications

For applicants with business interests: full corporate structure chart, beneficial ownership declarations, audited financial statements for the past three years, and any relevant regulatory filings.

What to do next

If you are in the early stages of evaluating a Caribbean CBI program, the due diligence fee structure should factor into your total cost calculation from the start — not surface as a surprise after you've committed to an investment option.

If you have a straightforward background — no criminal history, no PEP connections, clean and traceable source of funds — your DD experience will be primarily a documentation management exercise. Budget $12,000–$15,000 for government fees, allocate agent fees for document preparation and interview coordination, and expect a four to six month timeline post-submission.

If your background is more complex — prior criminal matter, PEP exposure, business relationships in higher-scrutiny jurisdictions, or a prior CBI rejection — the pre-screening stage is non-negotiable. The agent you choose should have specific experience with your profile, not just general CBI processing.

Conclusion

CBI due diligence fees are not bureaucratic overhead. They pay for the vetting process that determines whether a citizenship application is approved, escalated for further review, or rejected.

In 2026, that process is more structured and more consequential than it was even 18 months ago. The ECCIRA framework means rejections propagate across programs, interviews are mandatory, biometrics are enrolled and shared, and the documentation lookback is substantially longer.

The applicants who navigate this well share a common approach: they engage an agent early, conduct thorough pre-screening before submission, disclose complicated matters upfront, and treat the documentation preparation as the substantive work it is.

The applicants who struggle are typically those who treat due diligence fees as a formality and documentation preparation as a last-minute exercise.

Due diligence costs have increased in 2026. The leverage that preparation provides has increased proportionally.
