Between 1892 and 1954, more than 12 million immigrants entered the United States through the Ellis Island processing station in New York harbor. To these immigrants, Ellis Island was a symbol of the American dream—once they passed through its gates, they could start a new life with opportunities that were not available to them in their countries of origin. Today, roughly one-third of our country's population is descended from those who were processed at Ellis Island, and the facility is now a museum dedicated to American immigration.
