The purpose of early immigration to the United States

Early days: Europeans opened up new routes. A large number of Europeans went to America to look for gold, open up manors and slaughter Indians, resulting in a shortage of labor, so they transported black slaves from Africa to America through the triangular route. Later, the slave trade was banned, and we had to transport workers from densely populated Asia to America to fill the labor gap.

Later period: American economic law exhibition is rapid, and a large number of people go to the United States to look for business opportunities.

After being colonized, Africans were sold to the United States one after another, but some unyielding blacks escaped and died millions.

Asians were tricked into going to the United States to build railways, and many people died. However, those who survived and repaired the railway were the first to get green cards there.

At that time, people went to colonize everywhere, and the purpose of going to the United States was also for their own interests.
