Correct me if I'm wrong, but H1Bs are time consuming/expensive to set up and greatly increase the risk/difficulty of hiring unless you have a process set up and in-house legal to deal with all the paperwork.
Large corporations maybe, but not small startups.
Immigrants who already have residency and a US work history work at US market rates. (Signed, an immigrant with residency, working at US market rates).
If you mean "hire cheap immigrants" to work in the US... yeah right! As soon as a hiring company reads "H1B" your application goes right in the bin. It's too much work, especially for smaller companies, but even larger ones know that it's work they don't need to do with so many applicants out there.
Indeed. To get an H1B visa for someone the job has to have been publicly advertised (ie on internet/YC job-board)... they are probably just going through the motions having already decided who they are hiring...
