There is no shortage of examples of such abuse. The enforcement has been lax and Labor Certification approvals were largely a rubber stamp. In the end, it puts foreign workers into precarious positions when labor market deteriorates or enforcement action like above happens.
The balance of immigrant vs US-based workers would be nice but that balance was upset a long time ago. H1B lottery is one example. How can the lottery decide who qualifies for the job? Why temporary workers? If these workers are so special, why not apply straight for EB or similar visa? Because it is faster and easier for employers without regard what happens to these workers after?
