My first real job (I'm a native-born US citizen) was in such a body shop. Everybody there got paid chicken feed.
In fact, the INS would check that the green card applicants were getting paid market wages. When an employee reached that point in the process, his salary was actually increased as appropriate. But for those of us that had no such immigration issues, we never got such an upward adjustment.
(Things may have changed since then. That was the early '90s, the time of a big downturn in the industry)
I got paid a little extra to do technical interviews for this purpose. A green card applicant had to prove that there were no available US citizens that could do the job, so we'd run an ad in the Times, soliciting applicants for that job. I would then give them technical interviews so difficult that they couldn't pass, thus proving that our employee was the only one qualified.
