What was the reaction of the United States to the mass migration of immigrants?

The Immigration Act of 1924 limited the number of immigrants allowed entry into the United States through a national origins quota. The quota provided immigration visas to two percent of the total number of people of each nationality in the United States as of the 1890 national census.The outbreak of World War I greatly reduced immigration from Europe but also imposed new duties on the Immigration Service. Internment of enemy aliens (primarily seamen who worked on captured enemy ships) became a Service responsibility. Immigrants enter the United States with dreams of a better life for themselves and their families. Rather than posing a threat to our democracy, they reinforce and enrich the values that make America the country it is. The United States is a country created and built by immigrants from all over the world.
