The first wave of Korean immigrants to the U.S. took place between 1903-1905. Some 7,000 Koreanmales came to Hawaii as farm laborers. Within a few years 1,000 of them returned to Korea. Approximately 2,000 of the early immigrants left Hawaii and came to the continental United States. Between 1907 to 1924 several thousand more Koreans came to the U.S. as "picture brides" (Houchins and Houchins, 1976).
