I am Ishan Shah. I graduate from US university with mechanical engineering degree in May 2012. My OPT expires in June 2013 but my visa expires in November 2012. I wanted to know that can I still apply for STEM OPT extension even though my F-1 visa has expired. Can you please provide me answer or any link to USCIS website for the case where a student can apply for STEM extension with F-1 Visa expired? Please let me know if you know anything.
