thread officially hijacked... congratulations all
To the OP... this topic or notion of reviewing and stamping someone else's (unlicensed) work is as tiresome as all this bias/racism discussion. The practice is illegal in a lot of jurisdictions for a reason, on the basis of a responsible charge argument, and, in my opinion, it should be universally rejected by the engineering profession on the basis of a "don't be a sucker" argument. I mean think about it, the only reason this ever comes up is because of two other unscrupulous parties upstream of the licensed engineer. Namely a cheapskate owner/client that is trying to get something for next to nothing and an unlicensed person offering engineering services at bargain basement prices without a license. Why be the schmuck that comes along and also undersells yourself to facilitate this unprofessional sham of a process?
When these "opportunities" arise, I suggest to tell the owner/client that they have wasted all the money they spent on the unlicensed worker, and you won't be needing any of their work product so don't bother providing it, but that you will consider taking the job, but you will have to start from scratch and charge full price.
