I applied for OPT-STEM extension reciept date June 5. 1yr masters OPT expired June 30. I lost my job July 31st due to Covid. Notified DSO within 10th day. August 13 application denied still waiting for denial letter. Is lack of employment/job loss reason for denial? Does the 60 day rule to find another job apply before STEM OPT extension is approved even though I had the 180 day leeway? What do you think the reason is and what are possibly my options?
