well, in my case i never went through indian consultancies.  I was not lucky enough to get H1b in first attempt and got it in 2nd attempt.  what surprises me about these consultancies is, they hire people from any background ( business, chemistry, maths, physics, engineering , computer science).  It is understandable that computer science students with some training will do well if given some opportunities in their related field.  I am assuming most of the jobs are related to computer field, so, how on  earth would those guys from different background will be able to work in competitive environment with just 3 months of training?  That is why i never went to those consultancies.  I am an engineer myself and i would nt waste my 18 years of education in my field and find a job in different field with just 3 months of traning.  I believed that i would be not be competitive enough in that job. 

anyways, it is very sad that people with real jobs are getting H1bs because of these consultancies who just make fake resume of 5 years of experience after 3 months of training.
