IMO one of the easiest ways to tackle the entire issue around H1B visas is to remove or separate the category where a visa is sponsored by company A for someone working as a contractor in company B. This arrangement is the major cause of the scenario where American workers are replaced by people on H1Bs. If there is genuine skill shortage then the company in need of the said skill can hire the engineers directly instead of going through a middleman whose business model relies entirely on keeping wages low.
