Second citizenship or residence by investment: two models, two kinds of rights

In the investment migration market, two acronyms recur: CBI and RBI. They sound alike and are sometimes sold as interchangeable, yet they answer different questions — "I want a new passport" versus "I want the right to live in a country." This piece separates the two models so readers can pick the right problem to solve.

Two models, briefly defined

CBI — Citizenship by Investment. The investor contributes or invests above a threshold to receive a country's citizenship and passport, usually within a relatively short window and with little or no requirement to live there.

RBI — Residence by Investment ("golden visa"). The investor first receives a residence permit. This is the right to live — and often work — in that country; citizenship, if available at all, only follows after years of residence and further conditions.

Where the differences lie

A simple way to remember it: CBI buys a passport for greater travel flexibility; RBI buys a foothold in a country to live in and, possibly, commit to over the long term.

Cost, tax and due diligence

On cost, there is no fixed rule that one is "cheaper" — it depends on the country and the route. But there are structural differences: a CBI contribution is usually non-refundable, whereas much of an RBI outlay (real estate, fund units) is a recoverable asset after a holding period.

Tax is a separate matter and does not come automatically with a passport or residence card. Tax obligations usually attach to actual tax residence, not citizenship on paper. This is a common misunderstanding that calls for dedicated tax advice.

Finally, every serious programme runs due diligence on identity and source of wealth. A transparent file with provable legitimate source of funds is a prerequisite in both models.

Which model to choose

The deciding question is not "which programme is best" but "what do I need". If the priority is travel freedom, a contingency plan, or a citizenship that does not require relocating — CBI fits. If the priority is to actually live, study or work in a specific country, with willingness to commit over time — RBI is the route.

Many families end up using both at different moments. The key is to start from the goal and then examine programmes — not the other way around. This piece analyses public information; it is not legal or tax advice.
