Read the excerpt from "How the Immigrants Who Came to Ellis Island in 1907 Compare to Arrivals Today": The U. S. tried to reduce this type of immigration with the 1924
Immigration Act, which introduced numerical caps or quotas based on country of origin. These quotas gave enormous preference to people from northern and western Europe
over those from southern and eastern parts of the continent. But despite intense fears that the latter type of immigrants could never really be American, they and their
descendants became an important part of the country.
