I am in the same situation except I received my H1 but would only start from Oct 1st. My OPT expired on July 10th, I haven't been working ever since because I didn't want to jeopardize my status JUST IN CASE...My employer offered to pay me after my H1 started, but i declined so ever since I have been unemployed and flying to Nepal on Sept and join again on October.... For 2 months you can only stay here and hang out and get bored out of your mind....
