Where did Americans immigrate from?

Some immigrants from the United States arrived by European colonists, but the earliest immigrants were British colonists, that is, yellow people.

Although the United States, an immigrant country with a history of more than 300 years, was originally established by British colonists, the British were not the first American immigrants, even among whites. The purest indigenous people in the United States are yellow people, that is, Indians. In the United States today, there are more than 3 million Indians as aborigines, which is less than 1% of the total population of the United States.

About 20,000 years ago, some nomadic tribes (Mongols) from Asia chased the cattle and crossed the Asian-American Continental Bridge (which was a Quaternary glacier and the Bering Strait was completely frozen) to the American continent, becoming the earliest American immigrants in history. After 10000 years of continuous reproduction, by the time the European colonists arrived, more than10.5 million Indians had lived in this land. Therefore, Indians were the first American immigrants.
