He has spoken against H1-B visa abuse versus H1-B visas per se, which is an attempt to arbitrage on Department of Labor requirement on "prevailing wage" by establishing headquarters in the boonies of New Jersey / Georgia, filing H1 applications with local (extremely low) prevailing wages, and then sending the workers on the "business trips" that amount to full-time employment to California, NY and Washington.

The prevention mechanism is fairly obvious, and it's to rank the H1 applications by salary instead of the current lottery system. Genuine employers like Google or Facebook don't need to game the system, it's the outsourcing shops employ this tactic to boost the margins. They're welcome to join the game by boosting their salaries, though.

From the US government point of view a US salary paid in the US is a net win over a salary paid in Ireland or Switzerland, as it's still subject to federal income taxes, so net win on revenue.
