Respected sir, I am professional badminton player working in Incometax dept bangalore, I got entry to participate in all England open 2015 International tournament its eligibility based on World ranking of badminton world federation (performance in international tournaments. By badminton world federation ) When I request my office for onduty they replied this tournament is not entitled for onduty or SCl. In DOPT they have given onduty or SCl to be given for national /international importance tournaments Earlier also office denied OD for other international tournaments, I requested ministery of youth afffirs and sports they sent letter to office saying NOC to employee given to participate in event with no cost to govt. So there is no SCl or od given from that time for international tournaments outside India. What have to do to get Onduty for international bwf organised tournaments outside india?

Waiting for experts input in my case pls help My mob 9844613174.
