Mass migration from Vietnam began in response to the Vietnamese government in the 1970s. During the North Vietnamese military offensive of mid-March 1975, many South Vietnamese citizens were pushed farther and farther south into Saigon. On April 30, the final U.S. troops and diplomats left Saigon and the country came under the control of the Provisional Revolutionary Government. As a result, the North Vietnamese Army (NVA) took control of the country and many Vietnamese became refugees and immigrated to the United States.Do, Hien Duc.
