Because there are some H1B workers that come over as translators or other non-tech professions. Like if you need a translator that speaks Swahili for some NGO it's way easier to hire a native Swahili speaker than possibly finding a qualified American that also speaks Swahili.

I do find it interesting that these trillion dollar companies can't find domestic workers, at their level of wealth they should simply be forced to pay for the education of Americans to create a funnel of workers rather than exporting this societal need to other nations.

There are a bunch of H1Bs working as teachers in my medium sized midwestern city, making around $50k. Then there are a bunch in the healthcare sectors making from $50k to $500k. I actually feel like they are legitimate reasons they are there, very difficult to get good healthcare workers in the midwest since no one good wants to go there.

There is a big problem with ethnic nepotism and ghost jobs. I have been struggling to get younger people in my network hired anywhere despite solid resumes. Continuing to issue H1Bs in the current job market was bananas.
