i had my opt denied too last year, and i was a graduating senior....ur and my case might be similar. i went back to my advisor's office and enrolled for classes right away, even though they were 3 undergrad classes. i later changed them to grad courses and i transferred to another school after one semester..tantai khallas tespachi...tara they asked for my cpt papers before they said the application was cancelled~! like quagmire said..u can contest if you like! but talking to ur advisor is the best way to go!
