Residency and Citizenship in Free Cities

A world that stopped insisting on one passport

The most consequential change in this field happened with very little fanfare. In 1960 most states treated a second nationality as a problem to be prevented. By 2020 around three quarters accepted it. Germany opened up in 2024, permitting multiple citizenship generally and shortening the road to naturalisation. Italy moved the other way in 2025, restricting descent claims to people with an Italian parent or grandparent born in the country, after decades in which a great-grandparent was enough.

Taken together this is a real and largely unremarked expansion of options. Citizenship by descent, naturalisation after a few years of residence, marriage, and now some sixty national visas written for remote workers: none of these require money in the usual sense, and between them they let far more people than at any earlier point decide where their life actually happens. Albert Hirschman’s distinction between exit and voice is the frame the movement uses for it. If you cannot change a place you can leave it, and a credible threat of leaving changes how you are treated while you stay.

The market in residency

Alongside the ordinary routes runs an explicit market. Five Caribbean states offer citizenship in exchange for an investment, under a floor of two hundred thousand dollars they agreed among themselves in 2024. Golden visas granting residency rather than nationality are far more widespread, from Panama and Paraguay to the United Arab Emirates. Portugal channels its programme into investment funds, Italy offers wealthy new residents a flat annual charge on foreign income in place of ordinary taxation, and Puerto Rico has run an incentive regime for years.

Two practical things are worth knowing about this field. The terms move constantly: Portugal removed its property route, Spain closed its programme in 2025, Italy raised its flat charge twice within two years. And residence and taxation are separate questions. Where you are taxed turns on day counts, on where your centre of life sits and, for Americans, on citizenship rather than residence at all. Choosing a jurisdiction well is a legal exercise rather than a purchase.

What a Free City adds

Against that backdrop the Free Cities offer is unusual for being cheap. Próspera opened residency and e-residency to anyone in the world for a flat annual fee an order of magnitude below any investment programme. Estonia’s e-Residency, which is not a Free City but pioneered the idea, has issued digital identities to well over a hundred thousand people from most countries on earth, most of whom use it to run a company inside the European single market from wherever they happen to live.

What is on offer differs too. An investment programme sells a document and the travel it unlocks. A Free City sells the rules themselves: a defined legal framework, a known fee, courts that work, and the freedom to leave. Albert Hirschman called that exit, and its value does not depend on ever using it, because a resident who can go elsewhere is treated differently by whoever governs the place they are in.

The movement also has projects aimed well below the investor market. Ciudad Morazán near Choloma was built for Honduran factory workers, with rents set against local wages rather than international ones. It is the clearest statement that choosing your own jurisdiction is not meant to stay a service for people who already have options.
