In a paragraph, describe three challenges faced by immigrants who came to the United States in the late 1800s.

Between 1870 and 1900, the largest number of immigrants continued to come from northern and western Europe including Great Britain, Ireland,  Scandinavia, and North Africa. These immigrants faced large problems including unemployment, (both because of their religion and because they were from a different place).
