I have been working for a Profit company for little over 2 years now. They filed for my H1B this April which got approved over a week ago and I got letter on the mail today. However, after employer filed for my H1B I had a change of heart and was planning on quitting job by the end of Sep 2016. So I never asked employer about my case even for a single time however my supervisor called me couple days ago to notify of approval. I do not have any job offers currently, but I am dead set on quitting. So, what are some reasons that I can give employer when quitting given my H1B suppose to start Oct 01, 2016.
