I mailed an I-765 form for OPT like more than a 3 months ago.So now I want to withdraw my I -765 application.The reason for withdrawal is due to I got an F grade in a subject unexpectedly.So now I have to register for one more subject to cover the F grade.So for this reason i have sent the written letter to the USCIS service center along with a copy of I-797 Receipt Notice which i got after applying the OPT.But its been more than a month requesting for OPT withdraw but still i haven't got any response for OPT withdraw and my OPT status still showing as Initial Review.And i'm gonna finish my last subject in a month so do i need to apply for the OPT again.Please help me out to solve this problem.Please reply back to this email ID "becute957@gmail.com" if you dont mind.
Thank You,
