H1B isn't like normal immigration in its effects on wages. They do come over here, but they are at the mercy of their employer to stay. This makes it so the employee can be far more abused (paid lower, working far more hours in worse conditions, ect.). A legal immigrant may be willing to work for a bit less, but since they are able to seek another job without being kicked out, they would have little effect if any on wages. An H1B can't fight and either has to take it or leave and be replaced by someone who is willing to be exploited. Thus they have a far great impact on lowering wages. There are protections under the law that are susposed to prevent this but they are wildly ineffective.
