you seriously consider motherjones to be a reliable source?
I am talking about many provisions in the immigration law which make it possible in the case of ABUSE to proceed to adjustment of status despite the abusive sponsor ( does not matter which route is chosen).
If your wage is below the standard one you can SUE your employer - and that lawsuit would be basis for the immigration waiver
Do not consider immigrants to be uneducated and stupid - all those fairy tales in the media about low wages or poor abused immigrants are just fairy tales.
are there stupid people? sure. is there abuse of different kind. of course.
but there is also a lot of legal ways to counteract it and people are doing it.
