He served as manager (electrical) for the J&K "Rail Link Project" under Indian Railway Construction (IRCON).
In an exclusive interview with AJA, a Tangkhul vernacular daily, Leishiyo Keishing stated that he entered politics with the main objective of serving the people at his prime age and not after superannuation, as many people opt to do.
In the 11th Manipur Assembly General Elections, he contested as a Naga People's Front (NPF) candidate and won the race, beating his nearest rival, Somi Awungshi of the BJP, by a huge margin of 4778 votes.
Leishiyo Keishing was initially inducted as a Parliamentary Secretary in the BJP-led Coalition Government of Manipur[4] until the position was scrubbed in 2018.
The poor condition of the constituency in terms of road connectivity and electrification, according to Leishiyo Keishing, will hopefully change with the implementation of various state and centrally sponsored programs.
