An interesting point here is that the client was asking for an immigrant hire. Here we have a conflict between human nature and the law. It is human nature for Americans to perceive immigrant hires as cheaper. It doesn't matter if pay is actually the same or not. For someone looking to minimize labor costs, an immigrant hire has a better "brand" when it comes to price. Here's a thought experiment. Suppose hypothetical Product X was mandated by law to sell at the same price no matter what the store. Now suppose this fact was not widely known and not even rigorously enforced. Some people would insist on buying Product X at Wal-Mart because they perceive Wal-Mart's prices to be cheaper. It doesn't matter if the prices are actually the same, or not. The upshot is that some people with hiring power will insist on getting some of that "cheap immigrant labor" whether it actually exists or not. I have no doubt that this harms American workers' pay.
