I am currently working at a firm through which I had applied for my Stem-Opt back in mid June. However, I will be leaving the company on 15th of August during which I will still not have my EAD card in hand as the application is still processing. So, I will definitely be unemployed for a few days. During this period am I allowed to use my remaining Standard OPT unemployment days even if I haven't received my Stem-OPT card? Please let me know if I can use it or else what other option do I have.
