Family CBI Planning: Including Dependents, Age Definitions, and Timing Strategy

Introduction: Family CBI Planning Complexity

Acquiring citizenship by investment for an entire family sounds straightforward but requires careful planning across several dimensions: the definition of qualifying dependents varies by programme, pricing differs significantly between programmes when family members are included, adult children approaching 18 face a timing cliff, and including parents and grandparents adds complexity and cost.

This guide examines the family planning dimensions of CBI across the five main Caribbean programmes, with particular focus on the definitions and timing considerations that most frequently affect family applications.

Dominica: Family Pricing in Detail

Standard Pricing

Dominica uses a tiered pricing model that adds fees per dependent:

Family Composition	EDF Contribution
Single applicant	USD 100,000
Main + spouse	USD 175,000
Main + spouse + 1 qualifying dependent	USD 200,000 (standard family of 3)
Main + spouse + 2 qualifying dependents	USD 200,000 (family of 4 — no extra for 3rd or 4th member under some interpretations; confirm current rules)
Each additional dependent beyond 2	USD 25,000
Each qualifying sibling of main applicant	USD 50,000
Each qualifying parent/grandparent (55+)	USD 50,000

Note: Dominica's pricing for families of 4 at USD 200,000 was competitive but the per-dependent structure means larger families incur significantly higher costs than Antigua's flat-family pricing.

Dependent Age Definitions — Dominica

Minor children (under 18): automatically qualifying; no additional conditions beyond basic KYC.

Young adult children (18–26): qualify as dependents if they are full-time students enrolled in an accredited university or educational institution. The student status must be documented:

• Enrollment letter from accredited institution
• Academic transcripts showing full-time status
• Evidence that the applicant financially supports the dependent

The "student" definition has been interpreted broadly in practice — a gap year student who intends to enrol is generally not qualifying; currently enrolled students are.

Permanently disabled dependents: no upper age limit. Documentation required:

• Medical certificate from qualified physician
• Evidence of the disability's permanence and the dependent's reliance on the principal applicant

Parents and grandparents (55+): qualifying dependents at USD 50,000 per person additional. Documents required:

• Birth certificate showing relationship
• Evidence of financial dependence on the main applicant (useful but not always strictly required)
• Full KYC/due diligence including criminal record certificate

Antigua: The Best Family Pricing in the Caribbean

Antigua's National Development Fund pricing for families is unique:

Family Composition	NDF Contribution
Single applicant	USD 100,000
Any family regardless of size (up to 4 members: main + spouse + 2 dependent children)	USD 100,000
Each additional dependent beyond 4	USD 30,000
Parent/grandparent (55+)	USD 100,000 additional

This flat pricing for families of up to 4 makes Antigua by far the most cost-effective Caribbean programme for married couples with 1–2 children. A family of 4 pays the same as a single Dominica applicant.

For families of 5–6, Antigua remains competitive: USD 100,000 + USD 30,000 per additional dependent.

Antigua's Residency Requirement

Unlike Dominica (no residency requirement), Antigua requires citizenship holders to visit Antigua for a minimum of 5 days within 5 years of receiving citizenship. This is the most minimal residency requirement of any Caribbean programme (other than St Kitts, which has eliminated residency requirements entirely), but it should be planned for.

Timing Strategy for Adult Children Approaching 18

One of the most common and time-sensitive planning issues in family CBI is the dependent child approaching age 18. The eligibility rules are:

• Under 18: qualifies as a minor dependent
• Exactly 18 and enrolled as a full-time student: qualifies (student extension)
• Over 26 (or 25 depending on programme) and not a full-time student: does not qualify

The Timing Cliff

If a child will turn 18 during the application processing period, they must be included in the application before their 18th birthday to be classified as a minor dependent. The CBI programme uses the age at the time the citizenship certificate is issued (not at the time of application submission) for some programmes, and at the time of submission for others.

Important: each programme has its own rule on the relevant date:

• Dominica: age at time of citizenship approval
• Antigua: age at time of application submission
• St Kitts: confirm with CBIU at time of application — rules have varied

Practical Guidance

For a child turning 18 within 12 months of planned CBI application submission:

1. Start the application process immediately — do not wait
2. If the child will turn 18 before the expected citizenship certificate date, confirm whether they will still qualify if enrolled as a full-time student by that date
3. If the child cannot be included as a minor dependent due to timing, assess whether they qualify under the student extension
4. If neither route is available, consider a separate application for the adult child (separate investment required; most programmes allow adult children to apply independently with their parent as qualifying relationship)

Including Parents and Grandparents

Who Qualifies

All five Caribbean CBI programmes permit inclusion of parents and grandparents (typically those aged 55+) as qualifying dependents. The age threshold of 55 applies to:

• Parents of the main applicant
• Parents of the main applicant's spouse
• Grandparents (usually both paternal and maternal lines)

Pricing for Parents

Programme	Cost per Parent/Grandparent
Dominica	USD 50,000 per person additional
Antigua	USD 100,000 per parent (charged separately; same as a new family unit)
St Kitts	USD 50,000 per parent (approximate — confirm current schedule)
Grenada	USD 50,000 per parent
St Lucia	USD 20,000 per parent/grandparent (most cost-effective option)

St Lucia's parent pricing at USD 20,000 per person is substantially cheaper than other programmes, making it the most cost-effective for families wishing to include older parents.

Due Diligence for Parents

Including parents adds due diligence requirements:

• Criminal record certificate (all countries of significant residence)
• Medical certificate (some programmes require health clearance for older dependents)
• Evidence of relationship (birth certificate of the main applicant showing the parent)
• Financial documentation (typically less extensive than for main applicant — parents are dependents, not investors)

Parents with health conditions should note that some programmes' medical certificate requirements may raise issues; however, health conditions alone do not generally disqualify unless they create a significant public health concern.

Including Siblings

Dominica and Grenada permit inclusion of siblings of the main applicant as qualifying dependents. This is an unusual feature not available in most other Caribbean programmes.

Dominica: Sibling Inclusion

A sibling of the main applicant can be included at an additional cost of USD 50,000 (same as a parent). Requirements:

• Evidence of sibling relationship (birth certificates of both applicants and shared parent)
• Full KYC/due diligence (same as a co-applicant)
• The sibling must be financially dependent on the main applicant or meet an alternative dependency criterion

In practice, "financially dependent" is interpreted to mean the sibling is not independently employed at a level that would qualify them for their own CBI; or is a student; or has a disability.

Grenada: Sibling Inclusion

Grenada permits sibling inclusion at USD 75,000 per sibling.

The "Adding After" Option: Post-Citizenship Additions

Some programmes permit adding family members after the main applicant has received citizenship:

Programme	Add Spouse Post-Citizenship?	Add Child Post-Citizenship?	Notes
St Kitts	Yes	Yes	Subsequent application with reduced investment
Dominica	Yes	Yes	Subsequent application
Antigua	Yes	Yes	Subsequent application
Grenada	Yes	Yes	Subsequent application

Adding a spouse or child after citizenship is granted typically requires a separate application and payment of applicable due diligence fees (the investment contribution may or may not be reduced — confirm with CBIU at time of application).

This option is relevant for:

• Main applicants who marry after obtaining citizenship
• Main applicants with newborn children born after citizenship

Multi-Generational Planning Example

The Scenario: a main applicant (age 45), spouse (age 43), two children aged 14 and 19 (student), father (age 68), mother (age 65), choosing between Dominica and St Lucia.

Programme	Composition	Approximate Cost
Dominica EDF	Main + spouse + child (14) = standard family rate; 19-year-old student + father + mother = 3 × USD 50,000 each	USD 200,000 + USD 150,000 = USD 350,000 total (plus due diligence fees ~USD 30,000)
St Lucia NDF	Main + spouse + child (14) = USD 125,000; 19-year-old student = USD 15,000; father + mother = USD 40,000 (2 × USD 20,000)	USD 180,000 total (plus due diligence fees ~USD 30,000)

St Lucia is substantially cheaper for this large family configuration. The choice between programmes for large families should always include a cost analysis across all members.
