Referred to as the US, the USA, the United States, or simply the States, the United States of America is one of the world's most ethnically diverse nations. With its history of mass immigration dating from the 17th century, it is a "melting pot" of cultures from around the world
"America the Beautiful" includes both densely-populated cities with sprawling suburbs, and vast, uninhabited and naturally beautiful areas.
With the largest national economy in the world, America offers immigrants the opportunity to achieve greater material prosperity than was possible in their countries of origin, the opportunity for their children to grow up and receive an education, and the opportunity to make individual choices without the constraints of class, caste, religion, race, or ethnic group.
America is known for being a champion of human rights and personal freedoms, and both are constitutionally enshrined in the United States Bill of Rights.
Boasting a standard of living that is one of the best in the world, immigrants are attracted to this beautiful country as it promises life, liberty, and the pursuit of happiness.
