A passport is the most important thing to have when you decide to travel into other countries and one of the most powerful documents anyone can have in his possession. It is a travel document, usually issued by a country's government, which certifies the identity and nationality of its holder for the purpose of international travel. 

But not all passports are created equally. United Arab Emirates is ranked again in first place with visa-free access to 170 nations worldwide.

The Passport Index, which ranks annually the world's passports to identify which are the most powerful, released its most recent rankings in January. You can see the entire list of the most powerful and weakest passports by clicking here.
