Anil, based on your answer I would suggest that you are actually a dual status alien ---- Resident aline (taxed on world income by the USA ) till you left USA in June 2016 and thereafter Non-resident Alien ( taxed only on US sourced/connected income). So you file a form 1040 like normal and include world income for US taxes thru June 19th 2016 AND any income from US sources that you received for the rest of the year. This would imply that you do not report your Indian income and taxes thereon from the 20th. of June 2016.
I hope this helps --- if you more questions please feel welcome to either add to this thread or start a new thread and one of us will help you. Good Luck
