"The Melting Pot"

The "melting pot" is used to describe the U.S. immigration process whereby people from different cultures unify together to form a common culture. People come here for job opportunities, freedom, and a better living environment. The United States hosts about 43.3 million foreign-born people. About one-quarter are unauthorized immigrants, while the majority of the nation’s immigrants are in the U.S. legally. (Source)
