Immigrants played the most important role in American History

Immigration has played an important role in American history and the United States continues to have the most open immigration policy in the world. Before the era of rapid communications and transportation, America encouraged relatively open immigration to settle its empty lands. After certain states passed immigration laws following the Civil War, the Supreme Court in 1875 declared the regulation of immigration a federal responsibility. The Immigration Service was established in 1891 to deal with the big increase in immigration which started in 1880. From 1900 to 1920, nearly 24 million immigrants arrived during what is known as the “Great Wave”. The outbreak of World War I reduced immigration from Europe, but mass immigration resumed upon the war's conclusion, and Congress responded with a new immigration policy: the national-origins quota system passed in 1921 and revised in 1924. Immigration was limited by assigning each nationality a quota based on its representation in past U.S. census figures. Also in 1924, Congress created the U.S. Border Patrol within the Immigration Service. There was very little immigration over the next 20 years, with net immigration actually dropping below zero for several years during the Depression. Immigration remained relatively low during the 20 years following World War II, because the 1920s national-origins system remained in place after Congress re-codified and combined all previous immigration and naturalization law into the Immigration and Nationality Act of 1952. American agriculture continued to import seasonal labor from Mexico, as they had during the war, under a 1951 formal agreement between the United States and Mexico that made the Bracero Program permanent.
