Quick Summary: After obtaining Caribbean citizenship through investment, children born afterward typically register under bloodline descent, a mostly documentation-based process. A spouse married later, parents not included from the start, or a child born before but not listed initially must file supplementary dependent applications through the investment citizenship program, including background checks and government fees for each person.
One client obtained Grenada citizenship in 2021 when she was still unmarried. Three years later, she married, had a child, and wanted her parents—now in their sixties—to have passports so they could visit. She thought this was one procedure. In fact, it was three separate procedures, with three different sets of documents and three different fee schedules.
This is where many families don't receive clear explanation when signing the initial contract. Investment citizenship is granted to the individuals named in the approved application only. Anyone who joins the family afterward—through birth, marriage, or simply was not included initially—must go through a separate process.
Does investment citizenship automatically pass to children born later?
Most constitutions and citizenship laws in Commonwealth Caribbean nations allow a child born abroad to parents who are citizens to acquire citizenship through bloodline descent. Specific conditions—which category the parents naturalized under, where the child was born, when the child was born relative to the parents' naturalization—vary by country.
The key point to understand: legal entitlement is not the same as having documents. The child must still be registered with the vital statistics or citizenship authority of that country before a passport can be issued. Without registration, the entitlement exists on paper only, and the child cannot travel on that passport.
The right question to ask an advisor: "Does this country's citizenship law allow children born abroad to investment-category citizens to acquire citizenship through bloodline descent, and what is the specific registration procedure?" Ask before the child is born, not after. Basic information on citizenship laws for each country is available on the Grenada wiki and other country wiki pages.
How to register and obtain a passport for a child born afterward
For a child born in Vietnam, the typical process includes these steps:
- Register the birth in Vietnam as normal, obtaining an original birth certificate.
- Translate and authenticate the birth certificate according to the requirements of the citizenship-granting country. This step often causes problems — see the article on translation, notarization, and consular authentication.
- File an application for citizenship registration through bloodline descent or birth registration with the citizenship-granting country's authority, along with proof of citizenship and a copy of one parent's passport.
- Receive a certificate confirming the child's citizenship status.
- Apply for a passport for the child, including a photograph and biometric data if required by current regulations.
The entire process typically takes several months, depending on how quickly documents are authenticated in Vietnam and how fast the citizenship-granting country processes the application.
One detail often overlooked: if both parents remain Vietnamese citizens, the child born to them will also have Vietnamese citizenship. The child will hold dual citizenship from the start. Which passport to use where is covered in the article Vietnam's dual citizenship policy.
Spouse married after: not automatic and not free
Many people believe that marrying a citizen automatically grants citizenship to the spouse. Some Caribbean countries do have registration pathways for a citizen's spouse, but these typically require a minimum marriage duration and sometimes proof of residency. For someone not living in that country, this route is usually slow and impractical.
The more common approach is to add the spouse as a dependent to the investment citizenship application that has already been approved. Most programs allow adding a spouse after citizenship is granted without requiring another investment of the principal amount, but you must:
- Pay government fees and due diligence fees for the spouse being added.
- Undergo full background checks the same way the original applicant did.
- Prove the marriage is genuine: marriage registration certificate, wedding photos, evidence of cohabitation, sometimes an interview.
This third point receives increasing scrutiny. Marriages registered only weeks before the supplementary application is filed often trigger additional questions. The due diligence team wants to ensure citizenship is not being "sold through marriage."
The spouse being added needs a criminal record check—for Vietnamese citizens, this is typically a Type 2 certificate; see how to obtain it in the article Type 2 criminal record check. What due diligence teams examine is covered in the article Caribbean due diligence: what gets checked.
Adding parents later: age conditions and dependence
Parents are the most frequently misunderstood category. Each program sets its own conditions for parents to be considered dependents: some set an age threshold, others require proof that parents live with the applicant or are financially supported by the applicant. Some programs, like Grenada, allow parents below the standard age threshold and siblings at an additional fee.
Common obstacles when adding parents later:
- Proving financial dependence: bank statements showing monthly transfers to parents, documents showing where parents live. Vietnamese families often provide financial support in cash, leaving no paper trail.
- Medical examination: older adults may require more thorough screening, and abnormal results need explanation.
- Criminal record check: parents who have lived in multiple locations need records from each place.
- Vietnam passport for parents: many older adults have never obtained a passport or their passport expired long ago. Get this done first, as it is the primary identification document in the application.
- Your own birth certificate: this proves the parent-child relationship. Old handwritten birth certificates with misspelled parental names are a common problem.
Families with grandparents, parents, and grandchildren should also read the article three-generation family documentation to organize paperwork efficiently.
Who gets added by which route: summary table
The table below summarizes the scenarios we most commonly encounter. Specific conditions depend on each country and change over time, so use this table to know what questions to ask.
| Person to Add | Typical Route | Primary Documents | Common Issues |
|---|---|---|---|
| Child born after parents obtain citizenship | Bloodline descent registration | Authenticated birth certificate, proof of parent's citizenship | Slow authentication, child's name differs across documents |
| Child born before but not listed in initial application | Add as dependent | Birth certificate, criminal record check if old enough, medical exam | Child near or exceeding dependent age limit |
| Spouse married after | Add as dependent | Marriage certificate, criminal record check, medical exam, proof of cohabitation | Marriage too recent, insufficient evidence of genuine relationship |
| Parents | Add as dependent | Child's birth certificate, proof of financial dependence, criminal record check, medical exam | No paper trail of financial support, old birth certificate with incorrect names |
| Siblings (if program allows) | Add as dependent with surcharge | Proof of relationship, age and dependence conditions per country | Not all countries accept siblings |
| Adopted child | Add as dependent | Valid adoption decree, timing of adoption | Adoption too close to application filing date |
Looking at the table, only the first row is primarily a documentation process. All other rows require due diligence review, involve fees, and carry a risk of rejection.
Common documents to prepare
No matter who you're adding, these documents are almost always requested:
- [ ] Certificate of citizenship of the primary applicant (original or certified copy).
- [ ] Caribbean passport of the primary applicant.
- [ ] Documents proving relationship: birth certificate, marriage certificate, adoption decree.
- [ ] Vietnam passport and ID card of the person being added.
- [ ] Criminal record check for the person being added (typically from age 16 or 18 onward, depending on the country).
- [ ] Medical examination report in the program's required format.
- [ ] Passport-style photographs.
- [ ] Translations and authentications as required.
- [ ] Receipts for government fees and due diligence fees.
Risks to know in advance
Adding dependents later usually costs more than including them from the start. Government fees for supplementary dependents added after citizenship is granted may be higher than the fee for the same person if named in the original application, plus service charges and an additional round of translation and authentication. If your family is planning marriage or plans to include parents, consider this decision upfront. The investment cost estimator tool helps you compare both scenarios.
Regulations may change between when you obtain citizenship and when you add dependents. Caribbean countries have collectively raised due diligence standards, biometric requirements, and possibly physical presence requirements. A dependent added in 2027 may face different rules than the primary applicant approved in 2021.
Missing the dependent child age limit is a point of no return. Many programs set an age cap for dependent children, typically requiring the child to be unmarried and financially dependent. After that birthday, the child cannot be added as a dependent. Mark this deadline in your calendar.
Supplementary applications can be rejected. The person being added undergoes separate due diligence. If rejected, due diligence fees are usually non-refundable. No program guarantees approval in advance.
Vietnamese citizenship of the person being added. Parents or spouses who acquire additional foreign citizenship must also manage their Vietnamese citizenship status. This is handled by Vietnam separately from the Caribbean application process.

Next steps
Make a list of people you might want to add over the next five years—planned children, a future spouse, parents, a child approaching the dependent age limit—then ask your advisory firm about current conditions and fees for each, with dates noted.
If your family is preparing a Grenada application for the first time, this is the best moment to decide who goes in the initial application. Including people from the start is almost always simpler than adding them later.
