Please help me, I need to write an essay for Migration and Immigration in the 20th Century ...

When writing your essay, consider the following points:

1. How did immigration affect the economy of the United States in the early 20th century?
2. What were the social and cultural impacts of immigration on both immigrants and other Americans?
3. How did immigration laws and policies change over time?
4. What were the experiences of immigrants in the early 20th century?

To answer these questions, you can use primary sources such as newspaper articles, photographs, and oral histories. You can also use secondary sources such as books and articles written by historians.
