Vienner, we have rules about those H2b visas.
The jobs must be advertised. They can be advertised in a weekly newspaper with a circulation of as little as 50 people.
Suprise! No one responds!
Therefore there is no recourse save to hire people from shithole countries who will work for 1/2 of what Americans will work for.
No one's doing a H2B visa package for a manual laborer, those are just hired "locally", usually through a subcontract to another company hiring illegals. H2B's are when companies like Infosys and Tata, those two companies represent something like 70% of the H2B's given every year. They bother offer "IT consulting" services but are really used to replace US IT workers with Indian workers at a much lower pay. They are the reason the US IT sector is so screwed up right now, all the entry and junior level positions are being subcontracted leaving only the senior engineering, architects and managing positions.
The great news is that UCIS has removed "Software Programmer" from the list of "critical shortage skills", meaning those tens of thousands of H2B applications Infosys and Tata submit will need to be validated one at a time against a real job instead of bulk approved for consulting gigs. Will dramatically slow down their operations.
