Citizenship by Descent Strategy: Mining the Family Tree Before Buying a Passport

---

The reference section below extends this article with the market-wide data, costs, process and answers our readers ask for most — maintained by the Global Citizenship HQ research desk and updated as programmes change.

Zoom out once before deciding anything: second citizenships and residence permits are decade-scale assets. Programme details will shift — prices ratchet upward, routes open and close, requirements tighten — but the strategic logic holds: jurisdictional diversification, acquired early and maintained compliantly, has outperformed waiting in every year this industry has existed.

Citizenship Program Landscape: The Reference Table

To place the topic above in market context, here is the current landscape at a glance — figures verified against official programme publications for 2026:

Grenada	US$235,000 (NTF donation) or US$270,000+ real estate	4–6 months	≈146 incl. China; US E-2 treaty	None
Antigua & Barbuda	US$230,000 (NDF, family of 4)	4–6 months	≈147 destinations	5 days in 5 years

Cambodia	US$245,000 donation / US$305,000 investment	3–6 months	≈54 destinations	None
Jordan	US$750,000+ investment	6–9 months	≈55 destinations	None

The Real Cost Structure, Itemised

Whatever route this article points you toward, the cost anatomy is consistent across the industry — and the headline figure is never the whole story:

Cost component	Typical range	When paid	Notes
Government contribution / investment	US$90,000–US$800,000+	After approval-in-principle	The headline figure; donation is consumed, property/bonds recoverable
Due diligence fees	US$7,500–US$15,000 per adult	At filing	Non-refundable; funds international background checks
Government processing fees	US$250–US$10,000 per person	At filing / approval	Varies sharply by programme and dependent count
Professional / legal fees	US$15,000–US$50,000 per family	Staged	File preparation, compliance, submission, post-approval support
Document costs	US$1,000–US$5,000	Preparation phase	Apostilles, sworn translations, police certificates, courier
Passport & certificate fees	US$350–US$1,500 per person	After approval	Biometrics, issuance, oath administration where applicable
Property transaction costs (if applicable)	4–10% of price	At closing	Transfer taxes, registration, agent commissions

Rule of thumb across the industry: budget 15–25% above the headline contribution for a realistic all-in figure, and require an itemised fee schedule in writing before engaging any advisor.

Context worth holding while you compare options: investment migration is a treaty product. A passport’s value lives in the visa-waiver agreements behind it, and those agreements survive only where screening is credible. The programmes covered across our guides maintain their access precisely because refusals are real, interviews are standard, and information flows to partner governments — inconvenient for fraudsters, invaluable for legitimate families.

The Process Timeline, Step by Step

From first consultation to passport or permit in hand, well-run applications follow a predictable arc:

1. Weeks 1–2: Strategy and eligibility. Confirm the right programme against your passport portfolio, family composition, budget and objectives; identify any restricted-nationality or profile complications before money moves.
2. Weeks 2–8: Document assembly. Police certificates from every country of long residence (start the slowest jurisdictions first), civil documents, bank references and the source-of-funds evidence chain — apostilled and translated to programme standard.
3. Weeks 6–10: Compliance review and filing. Internal pre-screening against known refusal grounds, final file assembly, and submission through the authorised channel with due-diligence fees.
4. Months 2–5: Government due diligence. Multi-tier background verification, database checks and — in Caribbean programmes — the mandatory interview. Respond to any information requests within days, not weeks.
5. Months 4–6: Approval in principle. The government confirms your file passed; the qualifying investment is now completed within the programme deadline (typically 30–90 days).
6. Months 5–7: Naturalisation and passport. Certificate issuance, oath where required, biometrics, and passport delivery. Register any status with your banks proactively.
7. Ongoing: Compliance calendar. Holding-period end dates, passport renewals, newborn registrations and — for residence permits — renewal windows and presence logs.

The Document Checklist

Every application in this field runs on the same documentary spine — assembled early, it is the single biggest determinant of your timeline:

• Certified passport copies for every applicant (validity 6+ months beyond expected approval)
• Birth certificates — apostilled, with certified translations where not in English
• Marriage / divorce certificates documenting current family structure
• Police clearance certificates from every country of residence over 6–12 months (age thresholds vary)
• Source-of-funds evidence: bank statements, business accounts, sale contracts, inheritance or gift documentation
• Bank reference letters from institutions holding your primary relationships
• Professional reference and proof of occupation or business ownership
• Medical certificates including specified test results where required
• Passport-standard photographs to each programme’s specification
• Military service records where applicable
• Proof of residential address (utility bills, statements)
• Programme-specific forms — completed identically to supporting documents, to the letter

The preparation standard that separates fast files from stalled ones: every name, date and address rendered identically across every document, validity windows mapped so nothing expires mid-process, and certified translations from recognised translators only.

One pattern from a decade of client files deserves emphasis: preparation time is the only variable applicants fully control. Government queues are what they are; document assembly, source-of-funds evidence and name-consistency work happen entirely on your side of the table. Files that invest six careful weeks before submission routinely finish months ahead of files that rushed to file and then fed deficiency letters for a year.

Key Considerations Before You Commit

• Programme stability: favour statutes with functioning units and clean treaty records — and remember every historical closure grandfathered existing holders.
• Total cost honesty: model all-in figures (15–25% above headline), not brochure numbers.
• Family completeness: file every eligible dependent now; later additions are limited and pricier.
• Source-of-funds readiness: the documentation standard is bank-grade; build the narrative before applying.
• Dual-citizenship legality: confirm your current nationality tolerates the acquisition — before, not after.
• Passport utility for YOUR routes: check your ten key destinations against the actual treaty list, not aggregate counts.
• Exit mechanics: know the holding period and the realistic buyer at the end of it before choosing property routes.
• Tax layer separation: citizenship for mobility, residence for taxation — plan them as different decisions.
• Advisor verification: government-authorised agents only, checked against the official CIU lists.
• Timing: the market’s entire history rewards early applicants over waiting skeptics — prices ratchet one way.

Frequently Asked Questions: The Wider Picture

What happens after I receive the passport?

Passports renew normally (5 or 10 years by state) for life — citizenship is permanent and inheritable. Keep the naturalisation certificate safeguarded in certified copies, register children born after naturalisation promptly, honour any investment holding period, and update banks proactively with the new status.

Is dual citizenship legal for me?

All CBI states permit it; the question is your current nationality. Most Western, African and Latin American states allow dual citizenship freely; India, China, Japan, Singapore and Saudi Arabia prohibit or heavily restrict it; South Africa requires prior retention approval. Verify your combination before committing — sequencing mistakes are irreversible.

What travel access do these passports actually provide?

Caribbean CBI passports reach roughly 143–150 destinations visa-free or visa-on-arrival, including the Schengen area (90/180-day rule, ETIAS pre-authorisation) and the UK (up to six months per visit). Türkiye reaches ≈110 destinations plus US E-2 treaty eligibility. No CBI passport enters the USA visa-free — a B1/B2 visa or the E-2 route covers America.

Who can be included as a dependent on a family application?

Spouses and minor children qualify universally. Most programmes extend to children up to 25–30 while in full-time education, parents above 55–65, and in some cases (Grenada, Antigua) unmarried siblings. Include every eligible member at filing — post-approval additions are limited mainly to new spouses and newborns, at higher cost.

How long does citizenship by investment take from start to finish?

Preparation typically consumes 4–8 weeks before filing; government processing then runs 2–3 months (Vanuatu), 4–6 months (Caribbean core) or 4–8 months (Türkiye). The applicant controls the largest variable — document readiness — which is why prepared files consistently land at the fast end of published ranges.
