My Graduation 60-day grace period ends on Feb 15, 2018. My DSO has suggested that i cannot apply for OPT if i receive my F1 Reinstatement approval before that date. But, when i called USCIS Customer Service Center to ask about this, they have told me that i can still apply for OPT if the approval comes after the grace period. Did anyone face this situation earlier? If yes, what did you have to do? How can i convince my DSO that we can apply for OPT once the approval comes after the grace period?
