Answer:
Historically, the United States was a receiving country for migrants from different corners of the planet. However, the migratory streams that arrived in the country did not always have the same characteristics. Thus, the first waves of migrants that came to the nation came from England, while the colonies that were established in the territory belonged to that nation, as well as smaller waves of Germans, Irish and Scots.
However, the migratory waves of the late 19th and early 20th centuries had very different characteristics: it was no longer a cultural or religious migration, but a purely economic one, given that migrants came to the United States seeking to escape the poverty of their countries. Thus, these migrants came especially from nations such as Italy, Ireland or Poland, places that were in situations of poverty and economic need at the time.
