Tom,

Rhetorical question: Do those 'more than a few' cases represent enough statistic evidence to conclude that the majority of H1B positions have irregularities?

From what you say, it looks like they do. I am not trying to debate eternally with you about this, I understand your point of view, I really do, I just don't share it.

What worries me the most in all cases is the outcome of the fact that bona fide H1B holders end up mixed up with unscrupulous ones: prima facie we are all the same to US colleagues.

I do appreciate you letting me know your opinion though.
