USA. It is faraway country, on the other side of the world. It is country of contrasts and great opportunities. There are a number of time zones and two oceans, the Pacific and the Atlantic, between us. And what attracts me to it?

The US is state with rich cultural heritage and fascinating history. It has passed a long way of formation and has earned respect from other countries. During the Second World War the US had been a reliable support for the Soviet Union because it had helped much in the fight against the fascism.

America gave the world a lot of great people, such as Abraham Lincoln, James Fenimore Cooper, Ernest Hemingway and Martin Luther King. This list is endless. We should not forget about Christopher Columbus, because he had discovered this previously unknown continent.

A lot of cultures, mentalities and nations are intertwined in America. This has formed the current face of the country. Today, the US is a prosperous country, "the first economy of the world". Many people want to go to the US to get an education, make a career, or just see this truly amazing place.
