美国历史上经历了三次交大的移民浪潮，尽管这三次大的移民都是以欧洲为主体，但是在期间的比较自由的移民政策同样使来自亚洲，非洲的淘金者来到了美国。从欧洲各地的移民除了带来了不需要重新培养技术工人之外，还带来了欧洲各地的文化，清教，天主教，东正教的文化同时在美国存在而来自亚洲的移民除了带来了廉价的劳动力以外，还把神秘的东方文化带到了这里，而非洲原始的文明也随着大量黑奴还有合法移民一同来到这片新大陆。之外诸如中东，南亚次大陆等等文明随着美国当时比较自由开放的移民政策，陆续也都传入了这片新兴的文明上。各种文明在这里交融，编制成了新的文化，就是美国的多元文化

In American history, there have been three main immigration periods. Even though majority of the migrants were from the Continent, the lax immigration policy during these times also attracted many migrants from Asia and Africa, seeking for better life and fortune. European immigrants did not only contribute as skilled labors that helped American industries prosper, they also brought with them various religious practices such as protestantism, catholicism and eastern orthodoxism. Asian immigrants brought with them a mysterious oriental culture, in addition to a cheap labor force. The age-old African culture was brought to the United States through salvery trade and legal immigration from Africa. In addition, Middle Eastern and South Asian culture were also introduced to this young nation as a result of the liberal immigration policy that brought in migrants from these regions. The various blends of civilization create the cultural diversity in today's American culture.
