Have you ever wondered why Qualcomm is placing employment ads while it has been laying off employees and is struggling with mismanagement and financial troubles? Have you questioned why some of the ads appear in obscure local newspapers such as OC Register?
The company is hoping that no one would apply for the position that they have posted, and if someone does, they will find a way to declare him/her unqualified.
These ads are part of the "labor certification" process to obtain Permanent US Residency (Green Card) for a foreign worker that they have already imported and hired on an H-1B visa (work visa) for the position.
U.S. immigration authorities require companies to place such ads and demonstrate that the company "could not find a U.S. worker who could do the job", and therefore justify the need to grant permanent U.S. residency to a foreign worker for the position.
That is why Qualcomm hopes nobody would apply to their job posting and if someone does, they would find a reason to disqualify him/her.
This is an abuse that is rampant in the tech industry. They bring in cheaper foreign workers to the U.S. to replace U.S. workers.
