Citizenship by Investment Requirements in 2026: The Common Rules

Every legitimate citizenship-by-investment application has two separate tests: the investment must qualify, and the person and money behind it must survive due diligence. Passing only the first test is not enough. A contribution receipt or property contract cannot cure an unexplained bank transfer, an omitted refusal, a hidden beneficial owner or a family member who does not fit the legal definition of a dependent.

The active programs do not share one global application form, but they converge around the same controlling questions. This guide explains that common architecture. It is a requirements map, not a substitute for the current rules of the country you choose.

The common requirements

An eligible main applicant

The main applicant is normally at least 18, has legal capacity to enter the transaction and is not subject to a program-specific nationality, sanctions or security restriction. Some countries bar or apply enhanced scrutiny to applicants connected to specified jurisdictions. Current residence, not only nationality, can affect banking and due diligence.

A qualifying transaction

The money must enter one of the routes authorized by the program in force when you apply. That might be a non-refundable state contribution, approved real estate, a government-approved public-benefit project, a bank deposit or a business investment. A private transaction that resembles the route is not enough. Real estate usually must be in an approved project or meet a statutory value and holding period.

The advertised minimum is not the total requirement. Government processing, due diligence, interviews, passports, certificates, authorized-agent work and legal costs sit beside it. Use the True Cost Index to separate qualifying capital from money that is spent.

Lawful source of funds and wealth

Source of funds explains the particular money entering the transaction. Source of wealth explains how the applicant built the broader financial position that makes the transaction plausible. A complete file normally connects both:

• bank statements showing the money path;
• tax returns or assessed income records;
• employment, dividend, business-sale or property-sale documents;
• company ownership and audited accounts where relevant;
• probate, gift or inheritance records where relevant;
• loan agreements and lender evidence if financing is permitted;
• translations, certifications and apostilles required by the receiving authority.

A large balance is not proof of origin. The file must show where it came from, who owned it at every stage and why it belongs to the applicant. Read our detailed source-of-funds document guide before moving money.

Personal and reputational due diligence

Programs examine criminal records, sanctions, regulatory history, civil litigation, business disputes, adverse media, political exposure, immigration refusals and inconsistencies across jurisdictions. Adult dependents undergo their own checks. A minor may require different documentation but is not simply invisible to the review.

Disclosure is broader than a police certificate. An old visa refusal, expunged matter, name variation or politically exposed family connection can be explainable when disclosed and damaging when discovered independently. The safest rule is to resolve what must be disclosed before submission, not after a due-diligence firm raises it.

Complete civil and family records

Birth, marriage, divorce, adoption, custody, death and name-change documents must create a coherent legal chain. Adult children, parents, grandparents and siblings qualify only where the chosen program permits them and the dependency evidence meets its test. A relative living in the household is not automatically a legal dependent.

Family eligibility must be checked before the investment because changing countries later can change the entire family result. Compare the current definitions in our CBI family and dependent rules guide.

Interviews, biometrics and visits

The old description of CBI as universally remote and interview-free is obsolete. St Kitts and Nevis requires interviews, other programs can request them, and biometric or passport-collection procedures continue to develop. Antigua and Barbuda also has a five-day presence condition during the first five years of citizenship.

Regional Caribbean governments have announced stronger common standards, including a more substantive connection to the issuing state. Announced reform is not the same as an operative national day-count. The requirement that matters is the one enacted and published by the chosen country when the file is submitted and when the passport is maintained.

The usual application sequence

1. Pre-screen the applicant and family. Nationality, residence, refusals, criminal and regulatory history, political exposure and source-of-funds complexity are identified before engagement.
2. Choose the program and route. The decision includes cost, travel value, family fit, banking, holding period and the risk that a rule changes after approval.
3. Build the document record. Civil, financial and professional evidence is collected, translated, certified and reconciled.
4. Submit through the required channel. Caribbean applications normally pass through an authorized agent. The program authority, not the agent, decides.
5. Complete due diligence and interview steps. Authorities and their contractors test the disclosures and may request additional evidence.
6. Receive approval in principle or a decision. Program structure determines when the qualifying investment is completed. Many contribution programs protect the principal contribution until approval, while professional and diligence costs are already spent.
7. Complete the transaction and receive citizenship documents. The applicant then follows passport, oath, biometric, visit and ongoing obligations applicable to that country. Our post-approval citizenship owner’s manual explains the renewals, recordkeeping and continuing obligations that begin after approval.

What can disqualify an applicant

Common failure conditions include an undisclosed criminal or immigration history; a sanctions or security concern; inconsistent names or dates; unexplained third-party funding; adverse business conduct; false or altered documents; failure to meet a dependent definition; a prohibited nationality or residence connection; or a qualifying investment that does not follow the legal route.

Program approval remains discretionary. A clean checklist improves the file but does not create a right to citizenship. Any adviser promising guaranteed approval is promising an outcome controlled by a sovereign government.

The requirements decision

The right first question is not, “Can I afford the minimum?” It is, “Can every person, document and dollar in this file be explained to a skeptical government reviewer?” If the answer is not yet yes, the next step is preparation rather than payment.
