When deciding which country to visit, it is important to consider several different aspects, one of which is whether or not it is possible to obtain a visa upon arrival. Tourists may be looking for a way to travel that doesn't require much effort, or they may want to visit a different country without going through the time-consuming process of applying for a visa first. Both of these scenarios are valid reasons to look into alternate modes of transportation.

Whatever travelers’ reasons may be, a plethora of nations offer inhabitants of specific countries the possibility to receive visas upon arrival.
