You seem to be just 'me few months ago'. Graduated with STEM degree, worked in university research lab, but university did not enroll in E-verify program. I tried to extend the OPT for 17 month but unsuccessful. I found no way that I could extend the OPT for another 17 month. Immigration officer/HR told me that my employment would be terminated as my EAD expires.This led me to apply for change of status.
