Citizenship by Investment Requirements: What Every Program Actually Demands

Every active citizenship by investment program requires a qualifying investment, a clean criminal record, proof of lawful source of funds, and passage through at least one round of government due diligence. The investment itself takes one of three forms in virtually every program: a non-refundable government contribution, a real estate purchase with a mandatory hold period, or a qualifying fund or bond subscription. Biometric data, health checks, and certified translations of identity documents are universal across all programs regardless of jurisdiction.

Caribbean programs, specifically Antigua and Barbuda, Dominica, Grenada, Saint Lucia, and Saint Kitts and Nevis, sit at the lower end with government contributions starting between $100,000 and $250,000 for a single applicant in 2026. European programs cost significantly more: Malta requires a minimum total outlay of roughly 700,000 EUR when contributions, property, and fees are combined, and Turkey requires a minimum $400,000 real estate purchase. Vanuatu's contribution route sits around $130,000 and is one of the fastest programs globally, typically issuing passports within 30 to 60 days. A full breakdown of active programs and their current costs is here.

Most Caribbean CBI programs require zero physical presence before or after citizenship is granted, which is their primary advantage over residency-by-investment routes that require years of living in-country. Turkey requires no minimum stay. Malta is the notable exception in Europe, requiring 12 months of genuine residency before naturalization is approved, reduced to 36 months from the initial application date under the fast-track route. Applicants who want a second passport without relocating should focus on the Caribbean and Vanuatu rather than European programs that have residency triggers.

Due diligence is where applications fail, and the checks are more thorough than most applicants expect. Governments run background checks against international watchlists, criminal databases, and financial crime registries. Source of funds documentation must trace the investment capital back to a legitimate, verifiable origin, typically through bank statements, tax returns, company financials, or property sale records covering the prior three to five years. Applicants from certain nationalities face enhanced scrutiny or outright ineligibility, including nationals from sanctioned states. Dual nationals applying for a second citizenship through investment face their own home-country rules that may not permit dual nationality at all.

Most programs allow the main applicant to include a spouse, minor children, and in many cases dependent parents or adult children in full-time education under one application, for additional per-person fees. Saint Kitts and Grenada have among the broader definitions of eligible dependents, including parents and grandparents of any age if financially dependent. The per-dependent fees vary widely, typically $25,000 to $75,000 per additional adult dependent on top of the main investment. Including dependents is almost always more cost-efficient than separate applications, but each dependent still undergoes the same due diligence process.

A criminal conviction, even a minor one, in any jurisdiction is the most common disqualifier. Beyond that, rejected visa applications to major countries, prior bankruptcy, involvement in litigation flagged as fraud-related, or source of funds that cannot be documented to the government's satisfaction will end an application. Some programs explicitly bar nationals of specific countries regardless of their individual background. Applicants who have previously been denied citizenship by another CBI program must disclose that rejection, and failing to disclose is treated as misrepresentation, which results in permanent ineligibility across most programs.
