A Korean American is a person of Korean ancestry who was either born in or is an immigrant to the United States.
Although there were earlier immigrants to the U.S., Korean immigration to the U.S. is widely accepted as having begun January 13, 1903, when laborers arrived in Hawaii to work on sugar plantations. More began arriving after the passage of the Immigration Act of 1965.
KoreanAmericans are celebrating year 2003 as the 100th anniversary of Korean immigration to the United States.
Korean migration to Hawaii was largely a result of the efforts of Horace Allen, a missionary, medical doctor, businessman and self-styled diplomat and the Hawaiian Sugar Planters Association.
KoreanAmerican immigrants have settled primarily in California (345,882), New York (119,846), New Jersey (65,349), Illinois (51,453), Washington (46,880), Texas (45,571), Virginia (45,279), Maryland (39,155), Pennsylvania (31,612), Georgia (28,945), and Hawaii (23,537).
