For Plan-B and second-passport seekers
A hedge you can actually price.
Flag theory without the 28k concierge and the sales pitch. Design the second residence, the second passport and the exit, compare the routes, and keep the leverage on your side of the table.
What you’re up against
Salesy incumbents, and you can tell
The premium advisory tier works, but its buyers trust it least: every recommendation happens to be the program the firm sells. You want the map before you meet the salesperson.
Second passport, real timeline
Citizenship by descent, by naturalisation and by investment run on wildly different clocks and rules. Knowing which is genuinely open to you, and how many years it actually takes, is the whole decision.
The exit tax nobody mentions first
Leaving a high-tax country can trigger a charge on unrealised gains. A Plan B designed without the departure side is only half a plan.
Golden-visa goalposts move
Spain closed its route in 2025, Portugal dropped real estate, Greece re-tiered its thresholds. A plan built on last year's program is already stale before you act on it.
How this works for you
The portfolio framing, self-serve
The design outputs several configurations (a low-tax residence, a citizenship-track base, a Schengen-safe split), each with its tradeoff named. Flag theory as software you drive, not a pitch you sit through.
Design your options→Citizenship route and clock, named
Each configuration states its citizenship route and rough number of years, so a second passport becomes a plan with a date on it, not a vague someday.
Versioned, sourced facts
The trust layer puts an effective date and a source on every figure and flags when a program has changed, which directly answers the stale-brochure problem the head of the market runs on.
Model the residence-presence year
The builder checks that your split actually meets the presence a residence renewal or naturalisation requires, the detail that quietly sinks Plan Bs assembled from separate calculators.

A worked example
A founder de-risking into UAE residence and an EU passport track
Sample data, verification pending.
You have had a good exit and want optionality: somewhere low-tax to be resident now, and a strong passport on a clock for later. Say UAE residence, roughly 200 days, with an eye on an EU citizenship route running in parallel.
The UAE side does the tax-hedge job: 0% personal income tax, and a residency-certificate route that wants a genuine home or work tie, not just a stamp in a passport. But 200 days in Dubai accrues nothing toward an EU passport, so the citizenship track has to be a separate, deliberate leg with its own presence, and the exit from your current tax home may carry a charge on the way out. Two goals, two designs, and one honest tradeoff between them.
That tension is the product: a portfolio that shows the low-tax base and the citizenship base as distinct configurations, instead of pretending one country quietly does both jobs. Figures are sample data.
