Residence by Investment Due Diligence: Complete Guide 2026

---

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.

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.

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.

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.

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.

Residence 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:

Program	Minimum investment	Status granted	Presence required	Citizenship path
Portugal	€500,000 regulated funds	Golden Visa (renewable)	~7 days/year	Eligible at 5 years (A2 test)
Greece	€250,000–€800,000 property	5-year Golden Visa	None	7 years genuine residence
UAE	AED 2M (≈US$545,000) property or fund	10-year Golden Visa	Brief periodic entry	No practical path
Hungary	€250,000 fund units	10-year Guest Investor permit	Minimal	8 years + language
Italy	€250,000–€2M	2-year Investor Visa (renewable)	None for permit	10 years
Malta (MPRP)	€150,000–€200,000 total costs	Permanent residence	None	Discretionary only
Cyprus	€300,000 new property	Permanent residence	Visit every 2 years	Long residence
USA (EB-5)	US$800,000 TEA project	Conditional green card	Genuine relocation	5 years after PR
New Zealand	NZD 5M (growth) / 10M (balanced)	Residence (never expires once PR)	21 days (growth tier)	5 years
Panama	US$300,000+ property/securities	Permanent residence in ~30 days	1 visit / 2 years	5 years (discretionary)
Paraguay	≈US$70,000 SUACE plan	Permanent residence	Light	3 years
Singapore	SGD 10M (GIP)	Permanent residence	Substantive	2+ years (renounce others)

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.

Frequently Asked Questions: The Wider Picture

What do the background checks and interview actually involve?

Multi-tier screening: international due-diligence firms verify identity, litigation, sanctions and adverse media; source-of-funds evidence is traced transaction by transaction; and a 20–45 minute interview confirms your file in your own words. Honest, well-documented applicants pass; discrepancies between memory and paperwork are the main avoidable failure.

How much time in Europe do these statuses actually buy?

Visa-free passports get the Schengen 90/180-day allowance. A national residence permit (Greek or Portuguese golden visa) removes the limit for its issuing country entirely — unlimited presence there, plus the standard allowance across the rest of Schengen. Families wanting European lives buy the permit; travellers manage the count.

Will a second citizenship change my taxes?

Not by itself — taxation follows residence, not nationality (the US is the famous exception, taxing citizens worldwide). A Caribbean passport changes your tax position zero; moving your tax residence to the UAE, a territorial system, or a flat-tax regime changes everything. Plan the two layers separately and deliberately.

How is a golden visa different from citizenship by investment?

A golden visa grants residence rights — renewable permission to live in a country — while CBI grants the passport itself. Golden visas can mature into citizenship through naturalisation (Portugal at 5 years is the benchmark); CBI delivers in months but from a smaller set of states. Many families hold one of each: mobility now, EU endgame in parallel.

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.
