Choosing a second residency can be a smart retirement move, whether you want warmer weather, easier travel, a backup plan, or a place where your family can spend more time together.
Citizenship by Investment (CBI) is a legal process where a country grants citizenship to eligible applicants who make a qualifying investment (often a government contribution or approved real estate purchase). For Americans, CBI can be a way to build a “Plan B” passport—but it comes with clear legal steps and U.S. tax and compliance touchpoints you should understand upfront.
Below is a numbered checklist of Caribbean programs you can follow, plus a comparison table across Antigua and Barbuda, Dominica, Grenada, Saint Lucia, and Saint Kitts and Nevis.
Checklist: How to get a citizenship through investment as an American
1) Confirm your goal (passport, mobility, family planning, E-2 strategy)
Before comparing prices, be precise about what you want:
- A second passport for political or travel optionality
- A passport that supports a specific strategy, what’s your plan for the passport
- A family solution (spouse, children, parents, grandparents, siblings)
This matters because each program has different dependent rules, residence requirements, and cost structures.
2) Check that you qualify (and identify any due diligence risk early)
Most Caribbean CBI programs screen for:
- A clean background (police certificates and due diligence checks)
- A credible, documentable source of funds
- No sanctions or serious legal issues
- Consistent identity and personal history
Practical tip: If anything in your history could raise questions (old legal disputes, complex offshore structures, name changes, mismatched addresses), do a risk review before you commit to a stage in the process with non-refundable fees.

3) Decide who will be included in your application (now, not later)
CBI pricing and paperwork changes significantly based on family members. Common categories include:
- Spouse
- Children (often allowed beyond 18 if financially dependent and in school)
- Parents/grandparents (usually if financially dependent and meeting age thresholds)
- In some programs, siblings
Example: Antigua and Barbuda explicitly lists several dependent categories (including dependent children up to certain ages, and dependent parents/grandparents under conditions).

4) Pick the country first—then choose the investment route
Most Caribbean programs offer two main routes:
- Government contribution (fund option)
Usually the simplest path. You contribute to a national fund and do not get the money back. - Approved real estate
You buy government-approved property (often resort-linked). This can be appealing if you want an asset, but it adds complexity: project due diligence, contracts, escrow, holding periods, resale rules, and sometimes extra fees.
Your decision should reflect:
- Total cost for your family size
- Timeline expectations
- Whether you want a recoverable asset (real estate) or simplicity (fund)
- Any program-specific benefit (e.g., Grenada’s relevance for E-2 planning)
5) Work only through the required licensed/authorized channel
In most Caribbean CBI programs, you generally cannot apply directly as an individual. Applications are typically filed through a government-licensed/authorized agent (or equivalent authorized representative structure), and governments may reject improper submissions.
This is not just “paperwork”—your agent coordinates:
- Government forms and fees
- Due diligence submissions
- Clarifications and interview scheduling (if applicable)
- Investment completion steps after approval
FTB Mobility guides clients through Caribbean citizenship-by-investment programs that can support broader global mobility and facilitate travel and business access to various regions across the globe.
6) Build your document file (U.S. applicants should start early)
Expect to assemble and authenticate items such as:
- Passports (all applicants)
- Birth and marriage certificates (and divorce records if applicable)
- Police certificates (U.S. + any country of residence)
- Proof of address
- Bank statements and financial references
- Tax returns and/or income evidence
- Business ownership documents (if funds come from business activity)
U.S. reality check: Getting police certificates and properly certified civil documents can take longer than people expect—especially when multiple states/countries are involved.

7) Do a pre-submission “source of funds” and “source of wealth” check
This is where many applications slow down.
Before filing, your documentation should clearly show:
- How you earned the money (salary, sale of business, dividends, real estate sale, etc.)
- How the funds moved to the account (bank trail, contracts, statements)
- Consistency with your tax and business profile
If your funds trail is incomplete or contradictory, expect more questions during due diligence.
FTB Mobility assists investors throughout the due diligence process, conducting thorough documentation checks and preparation for citizenship-by-investment applications.
8) Submit the application and pay government fees (separate from the investment)
CBI programs typically involve multiple cost layers:
- Government processing fees
- Due diligence fees (often per applicant)
- Passport/certificate fees
- Professional/legal fees
- The qualifying investment (fund contribution or real estate)
Make sure you understand what is refundable and what is not before paying.
FTB Mobility assists investors with application preparation, fee processing, and submission, helping families successfully secure citizenship and relocate.
9) Complete interviews and respond quickly to due diligence queries
Caribbean programs have strengthened screening in recent years, and interviews are increasingly common.
Be ready to:
- Attend an interview (usually virtual)
- Provide clarifications or additional documents
- Answer questions about your career, finances, and background
Speed matters: the faster you answer queries, the smoother your timeline typically is.
FTB Mobility supports clients at every stage—assisting with applications, coordinating required fees, and helping families relocate successfully through investment migration programs.
10) Receive approval in principle (AIP), then complete the investment
In most programs, you complete the full qualifying investment after you receive approval in principle.
At this stage:
- For fund routes: you wire the required contribution to the authorized account.
- For real estate routes: you complete the purchase per the program’s rules (including minimum price, approved project, and holding period).
From application preparation to fee payments and final submission, FTB Mobility guides investors and their families toward a smooth and successful relocation process.
11) Finalize citizenship paperwork and obtain your passport
After the investment is confirmed:
- You receive citizenship/naturalization documentation (process varies by country)
- Your passport application is submitted and issued
Plan for practical follow-ons:
- Certified copies of your citizenship documents
- Secure storage and backups
- Renewals and future applications for family changes (births, marriages, etc.)
FTB Mobility supports investors through the full application process, including submission, government fee coordination, and helping families relocate successfully.
12) Update your U.S. compliance and your travel setup
This is the step many Americans overlook.
Practical items to plan:
- Keep a complete record of your CBI application and investment (banks may ask later).
- Understand how foreign accounts and assets may affect U.S. reporting.
- Remember: a second passport does not automatically change how you enter the U.S. or your tax outlook (see “What changes for U.S. citizens—and what does not” below).
Caribbean CBI comparison table (Antigua, Dominica, Grenada, Saint Lucia, St Kitts)
Figures below are typical minimums and can change; confirm current thresholds and fees before proceeding.
| Country | Typical minimum contribution route (USD) | Real estate route (starting point) | Typical processing time (range) | Family inclusion notes (high-level) | Notable U.S.-relevant angle | Key constraints / watch-outs |
| Antigua & Barbuda | ~$230,000 (NDF option) | ~$300,000 (approved real estate) | ~8–12 months | Broad dependent categories (spouse, children, parents; rules vary) | Often chosen for wider family structuring | Has a physical presence requirement (commonly referenced as 5 days within 5 years) – subject to change in 2026 |
| Dominica | ~$200,000 (single) / ~$250,000 (family bundle in some structures) | ~$200,000 approved real estate | Often ~8–12+ months depending on docs | Spouse, dependent children (including older dependents under conditions), dependent parents/grandparents (rules apply) | Clear, process-driven program administration | Interviews and strict due diligence; document prep timing matters |
| Grenada | ~$235,000 (NTF option commonly cited for small families) | ~$270,000 + additional government contribution (approved project route) | Often ~8–12 months depending on route | Dependents can include spouse/children and (in some cases) parents/siblings | E-2 treaty relevance is a major reason non-Americans shortlist Grenada | Ensure compliant investment structure; avoid non-approved “discounting/financing” schemes |
| Saint Lucia | ~$240,000 (NEF option commonly cited for a family bundle) | ~$300,000 approved real estate + admin fees | Often ~8–12 months (varies) | NEF pricing often structured around a main applicant + limited dependents | Straightforward fund route for many families | Interviews/identity verification are part of the process; fees stack quickly |
| St Kitts & Nevis | ~$250,000 (SISC option commonly cited for up to a family of four) | ~$400,000 approved development real estate (common minimum) | Often ~8–12 months depending on route | Family definitions and due diligence apply (including for older children) | Long-standing CBI market recognition | Interviews are required for main applicants; timelines depend on compliance readiness |
What changes for U.S. citizens—and what does not (direct answer)
What changes for U.S. citizens
- Taxes: The U.S. generally taxes U.S. citizens on worldwide income, so a second citizenship does not automatically end U.S. tax filing obligations.
- Reporting: Depending on your accounts/assets, you may have additional U.S. reporting obligations (commonly discussed concepts include FBAR and FATCA/Form 8938 thresholds).
- Banking/compliance: As a “U.S. person,” you can face more stringent bank onboarding and ongoing compliance requests abroad.
What does not change
- The CBI process: You still go through the same core steps—agent filing, due diligence, possible interviews, approval in principle, investment completion, and passport issuance.
- Approval standards: CBI programs apply due diligence standards regardless of nationality.
- Travel to the U.S.: Having a second passport doesn’t replace U.S. rules for U.S. citizens traveling to/from the United States.
Important: Tax outcomes vary by personal facts. Coordinate with a qualified U.S. tax professional before making decisions that affect filings or residency.
Tax touchpoints Americans should flag before applying (high-level)
Use this as a planning checklist—without treating it as tax advice:
- Citizenship-based taxation: A second passport typically doesn’t change U.S. filing status by itself.
- Foreign accounts/investments: If you will hold foreign bank accounts or overseas investment assets, expect more documentation and possible reporting thresholds.
- If your long-term goal is U.S. expatriation: That is a separate legal and tax process with high stakes. “CBI approval” should be viewed as a step toward the goal, not the end of the planning.
Common mistakes Americans make (and how to avoid them)
- Choosing the cheapest headline price instead of the lowest risk, clearest process, and best fit for family size.
- Starting documents late (police certificates, certified records, apostilles).
- Weak source-of-funds documentation (inconsistent bank trail, missing sale contracts, unclear business income).
- Buying non-approved real estate or misunderstanding holding period rules.
- Assuming a second passport ends U.S. tax obligations (it doesn’t, on its own).
When Caribbean CBI is not the right fit
You may be better served by:
- Residency-by-investment (if your goal is lifestyle relocation rather than a passport)
- A multi-step plan (residency first, citizenship later)
- A different region (Europe or Asia-Pacific) if you need long-term residence rights, schooling, or corporate expansion support
FTB Mobility often helps clients compare Caribbean CBI against European golden visas, Latin-American alternatives, and Asia-Pacific residency options as part of a broader mobility plan.

FAQ (Americans + Caribbean CBI)
- Can Americans legally get citizenship by investment?
Yes. Americans can apply to Caribbean CBI programs if they meet eligibility requirements and pass due diligence. - How long does Caribbean citizenship by investment take?
It varies by country, route, and document readiness. Many cases fall into a ~3–8 month range, but delays can occur. - Do I have to live in the country to keep the passport?
Some programs have minimal presence requirements (Antigua is a commonly cited example). Others may not require residence, but rules can change—verify before applying. - Does a second passport reduce U.S. taxes?
Not automatically. U.S. tax filing is generally based on American citizenship, not your second nationality. - Which Caribbean CBI is most relevant for an E-2 strategy?
Grenada is frequently discussed because E-2 eligibility depends on holding the nationality of an E-2 treaty country. - Can my spouse and children apply with me?
Usually yes, subject to each program’s definition of qualifying dependents. - What documents take the longest to obtain in the U.S.?
Police certificates, certified vital records, apostilles, and assembling a complete source-of-funds paper trail. - Does FTB Mobility help with real estate steps?
Yes—support can include identifying qualifying government-approved projects, coordinating the purchase process, and aligning immigration filing with investment milestones. - Do you coordinate with U.S. tax advisors?
Yes—Citizenship by investment (CBI) decisions often touch tax, reporting, and banking realities, so coordination is typically part of a well-managed case.
Can you help if I’m comparing Caribbean CBI with Europe or Asia?
Yes—FTB Mobility supports multiple programs globally, which helps clients choose based on outcomes, not geography.
