despair no more....keep working wherever you are save some...get married with a citizen here...a must and thenyou'll be all set..
2nd option..keep working save some..do your Ielts for AU or apply to Uk after getting back home..
ask/find an employer who will sponsor you for greencard...................unles your pasport's stamped with depotation...
just to get your brains working while not studying here...take online courses from Eurpoe or Austrailian colleges...they will accept...and once done you can go to Au and then transfer credits in school..
go back to nepal/india and continue strudy..
forget about your studies keep working here and chill
if you still have less than 3-6 months of being out of status find a lawyer immediately who will reinstate you in a college..
.if you've wasted only summer months after yourr opt expired, you can still get your F-1 visa back if its within 3 months range..try a UNiv immediately ..like there are few like that do like amburton univ (cheap too) in Texas, Finley in Ohio or JWU in providence or community colleges around you..and goodluck life doesn't end here
