>The United States is home to the highest number of immigrants in the world. An estimated 50.6 million people in the United States—a bit more than 15% of the total population of 331.4 million—were born in a foreign country. The number of immigrants in the U.S. has increased by at least 400% since 1965.

By the way, the USA takes more immigrants every year than any other country in the world. I myself went through the process and was treated with complete respect and it wasn't easy but well worth it to become an American and be welcomed into the Land of Milk and Honey.
