I agree, hence asking for more information when someone backs their claims with just, "trust me". - CIS is a anti-immigration think tank founded to provide numbers for the republican party. The study you link to is cherry picking data regarding location and prevailing wage. - There is also no way to prove if there is or is not a labor shortage. I think we can agree that this is something that can definitely be improved on. - Wages are long-tail distribution, so you're going to see lower tiers having higher enrollment. UCSIS reviews immigrants based on their experience and education levels, and will typically reject if the employer is under hiring. - You may be confusing the H1B with the O (Outstanding) visa. H1B is for talented labor only, it doesn't mean manager-level , so I'm not sure why that's your assumption. - Again, if you're assuming that you're filling the skilled labor shortage, that doesn't guarantee that you're hiring higher-quality skilled labor than the already-employed supply. The socioeconomic environment of skilled labor immigrants may be different enough to warrant such a gap, but that doesn't negate their current skills. We should definitely continue to question and evaluate the quality though. - And how exactly is a 3.7% drop in CS wages attributable to the H1B program? H1B immigration caps (supply) haven't changed for years. H1B visa != outsourcing. - You'll need to prove this claim with more than just "trust me" too. This may come across as harsh, but your feelings don't really matter on the issue because they are likely biased. The U.S. is currently at a record low of unemployment, and the H1B caps haven't increased in years, meaning that the H1B visa holders are not likely causing whatever it is you're feeling.
