My 12 months OPT is expired on Sep 15 2016 and I currently do not have a job right now. My employer stopped my marketing all of sudden. When I asked them they were telling me that my OPT is expired and not willing to start my marketing until I get my new card. I found on USCIS website that even if OPT is expired one can work legally for 180 days. My opt stem extension is still pending and waiting for approval. What I need to do now?
