Dependents of Americans working for private firms in Vietnam were not covered by the Presidential order, and so the education of those choosing to remain in Saigon was later provided by several private schools established in Saigon after the evacuation. One of these schools was called the “Phoenix Study Group”, whose students were described as “children of diplomats, wealthy businessmen and American civilians.” This follow-on school remained in existence until the fall of South Vietnam to forces of North Vietnam in April 1975.
