Answer D: 1907
American immigration history can be viewed in four epochs: the colonial period, the mid-19th century, the start of the 20th century, and post-1965. Each period brought distinct national groups, races and ethnicities to the United States
The peak year of European immigration was in 1907, when 1,285,349 persons entered the country. By 1910, 13.5 million immigrants were living in the United States. In 1921, the Congress passed the Emergency Quota Act, followed by the Immigration Act of 1924. The 1924 Act was aimed at further restricting immigrants from Southern and Eastern Europe, particularly Jews, Italians, and Slavs, who had begun to enter the country in large numbers beginning in the 1890s, and consolidated the prohibition of Asian immigration.
