When I read Sajhafan's response, I wanted to say something (that I never forged my documents) then I thought it would come out as boasting. He might be right, many of the students coming here might have used non-legit way of showing required proofs.

But then again I think it is important to point out one critical thing. Just because everybody else is doing it, don't fall for it. If you can, try to stay away from these illicit ways as much as possible; you never know - your past can come and hunt you. Remember, about 3-4 years ago there was a massive Green Card visa scandal where hundreds of people who got their GC via crooked attorneys in CA, via illegal means, had their GC revoked and possibly deported. Right path might be hard, but if you can afford it, take that path. Just don't do it because it is easier and everybody else is doing it.
