[1] After graduating from Chulalongkorn University in 1959, Boonsanong worked for the Thai government, preparing English translations of official manuals.

His skill in English and his familiarity with the Thai governmental structure gained him employment with the United States Information Service (USIS) in Bangkok as a writer and researcher.

After receiving the MA, Boonsanong returned to Thailand where he joined the staff of Thammasat University as a lecturer in sociology.

He was heavily engaged: writing papers, attending meetings, carrying out research, organizing and lecturing to hundreds of committed young people.

The student movement which was to overthrow the military dictatorship in the 1973 Thai popular uprising was heating up and Thammasat was at its epicenter.
