No confirmation/receipt no. of H1B.Waiting for rejection. Is it ok if I go 2 India upon receiving rejection & come bak?

I am on OPT, have EAD and offer letter for full time. I just graduated in May 2014 as a Master’s student.

I want to go to India and come back for full time in August 1st week, since I have around 40 days of free time. Is it safe to move out once I have H1B reject in my tracker? (i.e. my h1B was not selected in lottery).
