between 1900 and 1920 where did most of the migrants to the united states come from
History of immigration to the United States Between 1850 and 1930, about 5 million Germans migrated to the United States, peaking between 1881 and 1885 when a million Germans settled primarily in the Midwest. Between 1820 and 1930, 3.5 million British and 4.5 million Irish entered America. Before 1845 most Irish immigrants were Protestants. After 1845, Irish Catholics began arriving in large numbers, largely driven by the Great Famine.[26]
Ellis Island In the 35 years before Ellis Island opened, more than eight million immigrants arriving in New York City had been processed by officials at Castle Garden Immigration Depot in Lower Manhattan, just across the bay.[33] The federal government assumed control of immigration on April 18, 1890, and Congress appropriated $75,000 to construct America's first federal immigration station on Ellis Island. Artesian wells were dug, and fill material was hauled in from incoming ships' ballast and from construction of New York City's subway tunnels, which doubled the size of Ellis Island to over six acres. While the building was under construction, the Barge Office nearby at the Battery was used for immigrant processing.
