Immigration attorneys from Cohen & Grigsby explain how they assist employers in running classified ads with the goal of NOT finding any qualified applicants, and the steps they go through to disqualify even the most qualified Americans in order to secure green cards for H-1b workers.
Microsoft, Oracle, Hewlett-Packard, and thousands of other companies are running these kinds of fake ads in Sunday newspapers across the country each week.

This reminds me of the "literacy tests (http://www.slate.com/blogs/the_vault/2013/06/28/voting_rights_and_the_supreme_court_the_impossible_literacy_test_louisiana.html)" that were routinely given to blacks in the South up until the 1960's...the goal was to fail the person and keep them from voting no matter what.
In short, it doesn't matter how qualified you are for the job or how good a fit it would be, if you can't be hired through an H-1b visa then you ain't gettin' no job.
