The DOL has salary brackets based on job title, experience, and location but I'm sure there's a way for employers to stick H1B workers into experience brackets below where they should be, locate their H1B workers in offices in cheaper locations, or just simply pay them less than their domestic coworkers while still meeting the salary requirements.
