They returned to Shillong in 1956, and Swell worked as a professor of English at several Shillong area colleges. Swell contributed to the formation of the state of Meghalaya, breaking away from the parent state of Assam. He, with his wife's uncle,
Brington B Lyngdoh, and Stanley Nichols Roy, as well as other community leaders, conducted a campaign for the separate identity of their proposed state which would combine the peoples of the Khasi and Janintia Hills and other tribes from the Garo Hills and adjacent areas.
