Why did Ellis Island close?
With America’s entrance into World War I, immigration declined and Ellis Island was used as a detention center for suspected enemies. Following the war, Congress passed quota laws and the Immigration Act of 1924, which sharply reduced the number of newcomers allowed into the country and also enabled immigrants to be processed at U.S. consulates abroad.
After 1924, Ellis Island switched from a processing center to serving other purposes, such as a detention and deportation center for illegal immigrants, a hospital for wounded soldiers during World War II and a Coast Guard training center. In November 1954, the last detainee, a Norwegian merchant seaman, was released and Ellis Island officially closed.
