Dude, looks like during those years in college, you did not do well enough to keep abreast of developments in this consultancy biz and its impact on us students. Consultancies are messed up and as Mr. dHwasE said, you should think about consultancies as a last resort. If you can apply to about 30 positions a day (yes 30, I repeat), you will have a slim chance of getting into something by the time your OPT expires next year.
Remember, it is just one job, in most cases ,that will make you or break you, so that much more the incentive in trying harder!
In the meantime, I would imagine you would get hands on an I20 as plan B. My friends who applied to 30 or more jobs a day -- don't tell me there are no such positions out there or that many openings in the first place or that they are not sponsoring, I know that. In fact all of us know that -- are all working and have applied for H1. Consultancies bilked us and the US govt to the extent that the USCIS had to act this time. Hard work and talent is being sought out there, even if it is in limited numbers recently. I would imagine that you did all the research on these issues when you entered your final semester!
Having said that, I wish you good luck! Remember -- the number to hit each day is 30! Two months from now you will be frustrated, but around five months from now you will have something good to write home about!
