sounds like you have never been to the interview in the American Consulate abroad. If the company isn't well known, the amount of paparework you'd need to bring will be impressive, like tax, balance sheets, etc... reports for a nice number or previous quarters/years. And they seem to employ, at least in the Consulates in Russia, pretty smart nice people who like to ask very specific and targetted questions.

So while it isn't impossible and there are various arrangements out there along these lines, it isn't an easy exploitable scheme and once this particular worker is "caught" in such a scheme, his future visas/immigration chances become much more slimmer - this is even if the scheme is setup and operated by somebody else. As a result for hi-tech people the "white" ways like H1/L1 are much more preferrable. The H1 numbers for the last years even wasn't exhausted for example.
