World passports on WorldPath AI: making sense of what a second passport gives you
The decision to get a second citizenship almost always starts the same way. Someone hears about a specific country — Grenada, Malta, Portugal — and tries to figure out whether it is worth their time and money. What follows is usually a long detour through forums, sales pages from immigration firms, contradictory articles, and out-of-date tables. We tried to put the same material in one place, without the sales pitch.
What you will find here
A catalog of passports of recognized countries, all presented with the same logic. Every passport has its own page: global rank, the passport's tier (from Top-Tier to D-Tier), the number of visa-free destinations, the programs available to acquire it (citizenship by investment, investment residency with a path to naturalization, donation, real estate, government bonds), dual citizenship rules, residency and language requirements, family inclusion terms, and a comparison with other passports in the same tier.
How the tiers work
Every passport falls into one of five strength levels. Top-Tier passports sit in the first row: broad visa-free access, high weight of the issuing country in the global economy, strong reputation with banks and consulates. A-Tier passports are just below the first row, with almost the same level of mobility. B-Tier passports are mid-strength, often with a more regional concentration of visa-free access. C-Tier passports have limited mobility and sometimes serve as a stepping stone toward a stronger one. D-Tier passports have weak relocation utility. The tier is a quick read on how serious a passport is before you look at the program details.
How this differs from classic rankings
, Arton, and other analytical services publish their own set of metrics: Economic Mobility Score (the share of global GDP open visa-free), coverage out of 226 destinations, share of the world's territory with visa-free access, the issuing country's share of global GDP. These are useful cuts, and we use them as one of our inputs. WorldPath is not building another table on top of those metrics. The structured data on passports, programs, and rules is the material we feed into an AI assistant that works for the user, not for whoever is trying to sell a program. In a short conversation, the assistant works out what actually matters — who the passport is for, on what timeline, for what kind of life — and helps shape a strategy: which route is fastest, which is cheapest, which is realistic in a particular family and tax situation.
What you walk away with
A typical session moves through three steps. First, the user rules out passports that fail on the basics: too expensive, requires relocation, no dual citizenship, the visa-free coverage is wrong for what they need. That leaves three to five candidates worth reading about in full. By the end, the person walks away with a short list and a clear sense of the next step: continue the conversation with the AI assistant, talk to a specialist, or cross-check against the country page in the WRI, since the passport is only one part of a relocation decision.
When this page is most useful
When there is already a sense that a second passport is needed but not which one. When the and Arton tables have closed the mobility question without helping with what to do next. And when the next conversation should be with someone who is not tied to a single program.
