Based on an index calculated by Nomad Capitalist, a tax and immigration consultancy company, 24/7 Wall St. identified the most valuable passports in the world. The index ranks the power of passports based on five measures: the number of countries accessible without a visa (50%), whether or not a county can tax foreign nationals (20%), ease with which passport holders can obtain dual citizenship (10%), perception of the issuing country by people of other nationalities (10%), and freedom within the issuing country (10%), as measured by mandatory military service, press freedom, and government surveillance. A full methodological explanation is available from Nomad Capitalist’s “Nomad Passport Index 2021.”
The number of countries that passport holders from the nations on this list can visit without a visa came from Henley & Partners, a citizenship planning firm.
We also considered GDP per capita in current U.S. dollars, annual international departures, and population for the most recent available year from the World Bank.
