Malaysia is one of the world's most hassle-free countries to enter as a Westerner. Unlike the Latin American countries mentioned above, Malaysian immigration rarely asks for proof of onward travel, proof of funds, or even where you are going. Nor are there any forms to fill out upon arrival. It's easy.
And the world's most unfriendly country, according to the data? Bolivia took the dubious honor, scoring a 4.1 out of seven on a scale of “very unwelcome” (0) to “very welcome” (7). Venezuela and the Russian Federation were next.
Most US citizens prefer to travel to neighboring countries. The most popular destination for American travelers is Mexico, with 39.3 million tourists a year. However, tourists from the USA are warmly welcomed in many other countries of the world.
