But it seems a tautology that increasing skilled immigration quotas will depress my salary. If quotas are decreased, then the spots will be filled with only the best immigrants.
That said, most of my favorite technical peers are foreigners. So my ideal, selfish scenario would be for my company to have the ability to easily bring in H1B or similar, while our competitors can't :)
Minimum wage immigrant labor, on the other hand, absolutely must not lead to full welfare-state benefits (if I've not been mislead about the lifetime cost of Medicare), or the U.S. will be impoverished in the long haul.
It's unfortunate that the lobby for increasing H1B spots (which is probably a net positive for the whole U.S., in spite of my selfish doubts listed above) is politically allied with increasing unskilled immigration.
