a company, that is not really a company, keeps applying for tons of h1b. they usually have some title like consulting.
they get the h1b and don't even bring the programmers from India. they become "visa holders" companies.
the h1b's then start to look for work on their own, or the holder. and once the programmer is hired, the visa holder company gets paid, take 70% (or 60% if the programmer found the position themselves).
and this is how most h1b contractors that work on Google and such live. they will endure it for the 10 years the us forces them to stay as h1b. always trying to get transferred to the hiring company directly, and almost always failing.
the final company pays much more for a contractor via a visa holder, but they have the benefit of paying it via a small consulting company, so it won't show up as head count for the investors. everyone but the programmer wins.
