Adding children to your CBI application: rules, costs, and age limits (2026)

Last updated: April 2026

If you're evaluating Caribbean citizenship by investment (CBI) for your family, dependent inclusion is not a footnote—it's often the most consequential variable in your cost calculation and program selection.

Each Caribbean CBI program has its own rules: which family members qualify, at what ages, under what conditions, and at what additional cost. The differences are not minor. An adult child who qualifies under Antigua's rules may not qualify under St. Kitts'. A sibling who can be included under one program is excluded everywhere else. And post-ECCIRA (the regional due diligence framework updated in late 2025), biometric and interview requirements for dependents have tightened.

This guide covers the CBI application rules for children and other dependents across Grenada, St. Kitts & Nevis, Antigua & Barbuda, and Dominica as of April 2026. By the end, you'll know which program fits your family structure—and what it will realistically cost.

Note: ECCIRA (Eastern Caribbean Citizenship by Investment Regulatory Authority) introduced stricter due diligence and biometrics requirements from late 2025. Rules for dependent biometrics and interviews are evolving—verify the current requirements with a licensed authorized agent before submitting an application.

Key takeaways

• Grenada allows adult dependents up to 30 (if financially dependent) and parents/grandparents 55+
• St. Kitts allows children under 25 in full-time education; no siblings; parents/grandparents 65+
• Antigua is the only Caribbean CBI program that allows the main applicant's siblings as dependents—a meaningful advantage for families with strong multigenerational ties
• Dominica allows children under 25 in education and parents 65+
• Dependent costs range from approximately $10,000 to $35,000 per additional person depending on program and age category
• Children receive full citizenship—same passport, same rights, no age-out once granted
• Post-ECCIRA: children 12+ may be required to enroll for biometrics; adult dependents (18+) face more frequent interview requirements

Who this is NOT for

This guide is not the right starting point if:

• You have minor children and simply want to confirm they're included. Minor children under 18 are included as standard dependents across all four programs. The complexity addressed here is for adult children, siblings, and extended family.
• You're evaluating EU residency-by-investment programs. The rules here are specific to Caribbean CBI programs.
• Your family situation involves contested custody, recent adoption, or unusual guardianship. These scenarios require direct engagement with an authorized agent—the program rules have provisions, but case-by-case guidance is essential.
• You're looking for a program that includes adult siblings. Only Antigua allows this. If sibling inclusion is critical and Antigua doesn't fit your budget or timeline, there is currently no alternative Caribbean CBI program.

How dependent inclusion works in Caribbean CBI

Caribbean CBI programs allow the main applicant (the "principal applicant") to include qualifying family members as dependents on the same application. Dependents receive full citizenship alongside the main applicant—they don't apply separately, and their citizenship is not conditional on the main applicant's continued status.

The key variables are:

1. Who qualifies — relationship types (children, siblings, parents, grandparents)
2. Age limits — when adult dependents stop qualifying
3. Conditions — full-time education, financial dependency, co-residence
4. Additional costs — due diligence, processing, and government fees per dependent
5. Document burden — what each dependent must provide

Each program defines these independently, and the rules are not uniform across the region.

Age limits and eligibility by program

Grenada

Grenada's program is one of the more flexible for adult dependents.

• Minor children: Under 18, included as standard dependents
• Adult children: 18–30 if financially dependent on the main applicant (documented evidence required)
• Parents and grandparents: 55+ can be included; additional government fees apply
• Siblings: Not eligible

Grenada does not impose a full-time education requirement for adult children—financial dependency is the qualifying condition. This distinction matters: an adult child who has graduated but is not yet earning independently may still qualify under Grenada's rules where they wouldn't under St. Kitts' or Dominica's.

St. Kitts & Nevis

St. Kitts has one of the oldest and most established CBI programs. Its dependent rules are more conservative.

• Minor children: Under 18, standard inclusion
• Adult children: Under 25 if enrolled in full-time education (enrollment letter required)
• Parents and grandparents: 65+ with additional fees
• Siblings: Not eligible

The full-time education requirement for adult children is strictly enforced. A gap year, part-time enrollment, or graduation before the application completes can disqualify the dependent. Plan application timing accordingly if you have adult children in education.

Antigua & Barbuda

Antigua has the most expansive dependent eligibility in the Caribbean—particularly for families with extended family structures.

• Minor children: Under 18, standard inclusion
• Adult children: Under 26 if enrolled full-time; adult children 26–31 if financially dependent on the main applicant (subject to additional due diligence)
• Siblings of the main applicant: Eligible as dependents — this is unique to Antigua among Caribbean CBI programs. No other Caribbean program currently allows sibling inclusion.
• Parents and grandparents: Standard inclusion with additional fees

The sibling inclusion provision deserves emphasis. If your family situation includes an adult sibling whom you want to provide citizenship alongside yourself, Antigua is the only Caribbean program where this is possible. Additional due diligence fees apply for siblings, and they must meet the standard eligibility criteria (no disqualifying criminal background, clean due diligence). But the option exists—and does not elsewhere.

Dominica

Dominica's program is typically the most affordable Caribbean CBI option and has a straightforward dependent structure.

• Minor children: Under 18, standard inclusion
• Adult children: Under 25 if in full-time education
• Parents: 65+ can be included
• Grandparents: 65+ can be included
• Siblings: Not eligible

Dominica's affordability extends to dependent fees—it generally has the lowest additional per-dependent cost among Caribbean CBI programs.

Age limit comparison table

Dependent costs by program (approximate 2026)

Dependent costs in CBI applications have two main components: government fees (due diligence and processing) and in some cases investment top-ups (some programs require additional investment amounts per dependent). The figures below are approximate all-in additional costs per dependent excluding the main applicant's investment threshold.

Grenada

• Additional adult dependent (18+): approximately $25,000–$35,000 per person (due diligence + processing fees)
• Minor children (under 18): lower processing fees; typically $10,000–$15,000
• Parents/grandparents (55+): similar to adult dependent range, plus potential investment increment

St. Kitts & Nevis

• Adult dependent under 25 (student): approximately $15,000–$25,000 depending on age and application route
• Parents/grandparents 65+: similar range; government fees apply
• Minor children: processing fees; lower cost than adult dependents

Antigua & Barbuda

• Additional child (minor): approximately $15,000–$20,000
• Adult child: similar to minor child range if under 26 in education; higher for financially dependent adults 26–31
• Siblings: additional due diligence fees apply—expect similar to or higher than adult dependent range
• Note: Antigua's government contribution route requires an additional $10,000 per dependent beyond the main applicant investment threshold

Dominica

• Additional dependent: approximately $10,000–$20,000 per person depending on age and relationship
• Dominica's dependent fees are generally the lowest in the region

Dependent cost comparison table

Important: These are approximate figures for planning purposes. Actual costs depend on the investment route (donation vs. real estate), agent fees, legal fees, and any program fee adjustments that may occur. Always request a full itemized cost breakdown from an authorized agent before proceeding.

Mini-story: The Yılmaz family and Antigua's sibling inclusion

A Turkish family evaluating Caribbean CBI had a specific requirement: the main applicant wanted to include his younger sister, who was 24, financially dependent, and studying abroad. He had reviewed Grenada and St. Kitts but both came back the same way—siblings are not eligible.

Antigua was the only program that worked. Yes, the additional due diligence fee for sibling inclusion added cost. But the alternative was his sister applying for her own separate CBI program later—at far greater expense and without the family coordination benefit. Antigua's sibling provision made the family application coherent in one step.

The key lesson: program selection for families should start with eligibility mapping, not cost comparison. Cost differences often dissolve when you account for who can actually be included.

Mini-story: The Chen family and adult-child timing

A family with a 24-year-old son applying under St. Kitts ran into a problem six months into the application process. Their son had just graduated—school enrollment had ended—making him ineligible as a student dependent. The application was for St. Kitts, which requires full-time enrollment. Had they applied two years earlier or structured the timeline differently, the son would have qualified.

The family ultimately included him as a separate application at full cost. The lesson: if you have adult children near an age or education threshold, map the timeline before selecting a program. Grenada's financially-dependent provision—which doesn't require enrollment—might have been the better fit.

Document requirements for children and dependents

Standard documents for all dependents

• Birth certificate — original or certified copy, apostilled, with certified translation if not in English
• Valid passport — current, with sufficient validity
• Police clearance certificate — for all applicants over 16 (some programs use age 12 as the threshold post-ECCIRA)
• Medical certificate — health clearance from a licensed physician
• Passport photographs — specific format requirements vary by program

Additional documents for student dependents (adult children)

• Official enrollment letter from accredited institution confirming full-time status
• Proof of current enrollment — transcript, student ID, or institutional letter dated within the application window
• Evidence that enrollment continues — for applications with longer timelines, updated letters may be required

Additional documents for financially dependent adults

• Financial dependency declaration — notarized statement from main applicant
• Bank statements — showing main applicant's financial support of the dependent
• Evidence of shared residence or regular financial transfers — bank transfer records, utility bills, or similar

Additional documents for parent/grandparent dependents

• Proof of relationship — birth certificates establishing the chain of relationship
• Evidence of dependency if applicable
• Medical certificates — often more detailed for older dependents

Adoption and step-children

Legally adopted children are treated as biological dependents across all four programs, provided adoption documentation is complete:

• Adoption decree or order (apostilled)
• Birth certificate of adoptive parents
• Evidence of legal completion of adoption process

Step-children are generally accepted with:

• Marriage certificate connecting the main applicant to the child's parent
• Guardianship or adoption documentation depending on program requirements

Rules vary by program and by how the adoption or step-relationship was legally established. If your family includes adopted or step-children, verify the specific requirements with an authorized agent—don't assume equivalence to biological dependents without confirmation.

Document checklist for children (summary)

• [ ] Birth certificate (apostilled, translated)
• [ ] Valid passport (all dependents)
• [ ] Police clearance / criminal background check (16+ or 12+ depending on program)

• [ ] Passport photographs (program-specific format)
• [ ] School enrollment letter (if qualifying as student dependent)
• [ ] Financial dependency declaration + evidence (if qualifying as financially dependent adult)
• [ ] Adoption decree or guardianship documentation (if applicable)
• [ ] Biometrics enrollment (children 12+, post-ECCIRA — confirm current requirement with agent)

What citizenship means for your children

This is worth stating clearly, because it's what makes CBI family applications meaningfully different from residency programs.

Children receive full citizenship. Not conditional status, not a residency permit—the same passport as the main applicant, with identical rights in the issuing country.

Citizenship is permanent once granted. There is no age-out. A child who is granted Grenadian or Antiguan citizenship at age eight does not lose it at 18 or 25. It remains valid indefinitely.

Minor children's passports are typically issued with five-year validity (versus ten years for adult passports). They are renewed in the standard way.

Children can pass citizenship to their children. The citizenship is heritable, subject to program-specific rules on citizenship by descent. In practice, Caribbean CBI citizenship acquired through the investment program can generally be passed to the next generation born after citizenship is granted.

Practical benefits for children:

• Visa-free or visa-on-arrival travel to the countries the program passport covers (Grenada: ~140 destinations; Antigua: ~150 destinations; St. Kitts: 155+ destinations; Dominica: ~140 destinations)
• The right to live and work in the issuing country
• Access to the country's public education and healthcare systems
• For Grenada specifically: eligibility for the US E-2 investor visa treaty, which is available to Grenadian citizens

Education and career implications: A second passport from a Caribbean CBI program can open university application pathways in countries that extend preferential admission or fee treatment to citizens of program countries. Work visa applications to third countries also benefit from the additional passport. These are longer-term considerations, but they are real.

Post-ECCIRA requirements for dependents (2025–2026)

The Eastern Caribbean Citizenship by Investment Regulatory Authority (ECCIRA) formalized enhanced due diligence requirements across the region from late 2025. Key changes that affect dependent applications:

• Biometrics for children 12+: Post-ECCIRA, children aged 12 and above may be required to attend in-person biometrics enrollment. Previously, biometrics were generally only required for adults. Confirm current requirements for the specific program and application timing.
• Interviews for adult dependents: Interviews for adult dependents (18+) have become more common since ECCIRA's implementation. This is particularly relevant for adult children and siblings qualifying under Antigua's program. Not all applicants are interviewed, but the possibility should be factored into planning.
• Enhanced document standards: Apostille requirements and translation standards have been clarified and in some cases tightened. Documents that were previously acceptable may need re-certification to meet current standards.

These requirements are evolving. An authorized agent current with post-ECCIRA processing is essential—this is an area where the guidance shifts with program-by-program implementation.

CTA: Calculate your family's full dependent cost

Before selecting a program, map your full family application cost—not just the main applicant investment. Dependent fees, due diligence costs, and agent fees for each family member often equal or exceed the base investment cost for families of three or more.

How to evaluate the right program for your family

The dependent rules described above lead to a practical framework for program selection when children are involved:

1. Map all dependents first. List every family member you want to include, their current age, their status (student, employed, financially dependent), and their relationship to the main applicant.

1. Check eligibility, not cost. If a key family member doesn't qualify under a program's rules, that program is off the table regardless of cost. Antigua's sibling provision is the most common example of a feature that narrows the eligible set to one program.

1. Account for timing. If an adult child is 24 and near a program's enrollment requirement threshold, the application timing could affect their eligibility. Some families deliberately accelerate applications; others defer to the next year.

1. Request itemized cost estimates. Once eligible programs are identified, ask authorized agents for full cost breakdowns including all dependents. Don't compare programs on the main applicant investment alone.

1. Engage a licensed authorized agent. Caribbean CBI programs authorize agents who are responsible for application submissions. Due diligence on your agent matters—post-ECCIRA, agent oversight has increased.

Conclusion

Adding children and dependents to a CBI application is straightforward for minor children. The complexity begins with adult dependents, extended family, and cases where the family structure doesn't fit the most common template.

The headline points: Grenada's financially-dependent provision gives adult children up to age 30 the best chance of qualifying; Antigua is the only Caribbean program that allows siblings of the main applicant; Dominica is the most affordable entry point for families with minor children; and post-ECCIRA, biometric and interview requirements for dependents are more stringent than they were two years ago.
