[theophrastus]

Yes indeed. I worked with groups of Chinese chemists all on H1Bs. They had to work ridiculous hours and assigned the most mind killing labor. If they made trouble they were told they'd lose their job and it was deportation. Finally the company fired all its non-H1Bs, including me; eventually giving up the pretense and relocating overseas. Where was the department of labor and industry? One of my coworkers contacted them and they wouldn't even return the call. H1Bs are simply licenses for a form of slavery.
