On the top of the list stands Singapore, which can claim to having the strongest passport in the world, allowing its holders to enter 159 countries (more than any other country) either without a need for a visa or with a visa on arrival.

Singapore passport holders can enter countries like China, Cuba and Brazil visa-free, something that US passport holders cannot do.
