So tell me, why do you think the gang of 8 rejected his proposal to raise the cap on the number of H1b visas?
H1B is an a abject scam. The law as written is fine, the reality though is it is violated wholesale and no one cares.
H1Bs are meant to be for companies to hire folks when they cannot find a native person capable of doing the work.... so that means things like what Disney et al are doing, are flagrantly illegal under the law, and they just keep doing them anyway because no one will enforce the law.
H1B is to skilled workers what Illegal immigrants are to unskilled, they are both backed by the same groups and money. If Cruz is pushing expanding H1B which he is, he is beholdened to the same puppet masters are the rest of the GOPe. He just as a more palatable wrapping paper.
