I think I agree with you generally, but I would say that;
1. Doesn't Japan admit very few immigrants of any kind, even legal? I think they are one of the most automated societies on earth, and I think they have no qualms about saying they want Japan to remain Japanese.
2. Studies examining the costs of the different immigrant groups would be welcome, but I don't think its unreasonable to analyze the effects of both legal and illegal immigration together when looking at their effect on things like wage suppression, social service costs, etc. I mean, if the ability to hire an illegal immigrant under the table allows for wages to be driven down, then so too would the ability to hire a legal immigrant at a wage at or approaching minimum wage. Clearly the former is worse, but it makes no sense to focus on illegal immigration exclusively when many of the effects are basically identical.
I was in Japan 10 years ago, they still had elevator operators(there's automation for you), and second Japan birthrate is so low they are going to lose population next year,

It is unreasonable to consider the effects of legal immigrants and illegal aliens together because (as this report intended) combining them only serves to obfuscate the critical fact that illegal aliens do not belong here and are stealing from us all through involuntary subsidization. If anything, this "study" diminishes the positive contributions valued newcomers make to our society and glosses over how they, unlike the invaders, strive to join the American ideal instead of attempting to recreate the environments they escaped from.
This report reminds me of the Soviet Union's ceaseless reshuffling of facts to promote it's agenda. History castigates them and will do the same to these attempts to whitewash a trend that harms the majority of Americans for the sake of a privileged minority's profit margin.
