Depending on your passport, travel can be as simple as just booking flights, finding a hotel, and, then simply going.
But, as Visual Capitalist's Avery Koop details below, for many across the world, it’s not that easy - a number of passport holders need to obtain a travel/tourist visa prior to arrival. These visas typically require approval from the destination country’s government that can take weeks or months.
Japanese passport holders, for example, are able to visit 193 countries without pre-approval (nearly every country on Earth). Afghans, on the other hand, can only visit 27 countries with the same level of ease.
This ranking uses data from Henley & Partners, which determines the number of countries to which a passport holder has visa-free access.
