I actually saw this with a few of my colleagues that worked at Amazon. There was one superb engineering — one of the best Android developers I've ever worked with. Our project ended and, I had the freedom to leave Amazon and jump to another company (which I did), but he was stuck. He ended up having to move his family from SF to Seattle just to keep his job all in hopes that he didn't screw up his H-1B visa process.
