Back then, wasn’t everybody legal?
From 1880 to 1924, over 25 million Europeans migrated to the United States.[65] Following this time period, immigration fell because in 1924 Congress passed the Immigration Act of 1924, which favored immigrant source countries that already had many immigrants in the U.S. by 1890.[69]
Up to 1924… still, the fact is it was organized, government sanctioned immigration.
