Borjas's results consistently lie at the furthest extreme of existing studies. You can see this in the survey I linked. If I claim that the aggregate of research doesn't show a long-term effect of immigration on wages, it's not a rebuttal to cite a subset of data from one tail of the distribution. Less abstractly, Borjas's methods are viewed as suspect by other economists working in this area. See, e.g, this review[1].
