I don't know if you're trolling, but in this case H-1Bs are being used to outsource: large consulting companies obtain H-1Bs for their (stereotypically Indian) employees, bring the employees into the US for 3-6 months to learn how to do the job, then send them back to India, from where they complete the job remotely, and where they can of course be paid much less due to the lower prevailing wages/cost of life. This is a classic outsourcing strategy. Insourcing is the complete opposite, see https://en.wikipedia.org/wiki/Insourcing https://en.wikipedia.org/wiki/Insourcing.
