It’s difficult to determine the “most useless” passport in the world definitively, as the value of a passport can vary depending on various factors such as visa-free travel options, diplomatic relations between countries, and individual circumstances. However, there are certain passports that generally have more limitations in terms of visa-free travel.

For example, passports from countries facing political or economic challenges, travel restrictions, or limited international relations might have fewer visa-free travel options. Additionally, passports issued by territories or regions with limited recognition or sovereignty might have limited international recognition and travel privileges.

It’s worth noting that the value of a passport can change over time as diplomatic relations evolve, and countries negotiate visa agreements with each other. Rankings of passport power and visa-free travel often change on an annual basis.
