1) An avenue [2] for members of the workforce to report H-1B abuse. People on H-1B are offered some protection against retaliation.
2) Targeted onsite visits at worksites of employers who have larger fraction of their employees on H-1Bs, and those who sent employees to other locations.
Together, this seems to be aimed at curbing H-1B abuse by staffing companies. Some Silicon Valley employers - like Apple, Cisco etc - who use these staffing companies extensively might also be affected. But overall, this should be good news for both H-1B employees and citizens/permanent residents.
