Why do you see giving more visas as a government interference in labor markets? In my view it's the opposite, a perfectly free labor market would be one where anyone can apply to a job. Restricting immigration by denying visas is a government interference in the market. So more visas means less interference. (Note: I'm not claiming anything about whether it's a good idea or not).
