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.
