How did the United States become an immigrant country?

America has always been a country of immigrants.

Native Americans are people who migrated from Asia, especially Siberia, through the Bering Strait tens of thousands of years ago and are called Native Americans.

After Columbus discovered the New World and opened up a new air route, European powers including Portugal, Spain, the Netherlands and France colonized America one after another.

Britain established Jamestown, the first permanent settlement near chesapeake bay, in 1620, and a large number of Europeans moved to North America. In order to develop local agriculture, the colonists kidnapped blacks near the African coast by some despicable means and sold them to America as slaves to do farm work in the fields.

Later, because of the conflict between the colonists and Britain, the North American people sought independence, and the United States was founded in 1776.

Later, with the expansion of American territory and the rise of the gold rush, many Asians immigrated to the United States to seek gold and build railways. The earliest wave of immigrants from China to the United States also began in the middle of19th century, with the aim of building railways as laborers.

Due to the growing strength of the United States in the 20th century and its security and stability during World War II, people from all directions immigrated to the United States. The United States is becoming a unified immigrant country.
