Ow did the new immigration from southern and eastern Europe affect American society, politics and economy from 1890 to 1920?

the research paper need to cover the New Immigration and follow the standard format.

there were few nations that primary immigrated, please be creative and use as much examples as possible, in addition i really need to include polish immigration, one paragraph about it will be enough.

it needs to contain AT LEAST 3 primary sources!

im reallly looking forward for the outcome!

thank you!
