My OPT expires on June 15th, 2007. I have 60 days grace period after this which is August 15th. Do I have to attend school by August 15th (within 60 days grace period) or can I just issue my new I-20 within this 60 days grace period time and go to school from last week of August or September in order to be in status. Any one in this situation who knows the answer. Thanks in advance.
