deported - it wouldn't be prudent for me to suggest that you quit school. but you are at a better position to decide if you really wish to withdraw and to weigh your options at this point. i think with F2A not retrogressing till Sep 30, I think you will at least want to wait till then to decide. you might just get your GC by then, who knows!
what do you think?
one other option is to call the USCIS. Sometimes you get to talk to an amazingly informative person at the other end.
