devil's advocate - if they are HQ'd in the US, is hiring US citizens that big of an ask? why do they need cheap overseas labor?
Local SMEs (regulatory requirements), sales, local implementation teams, HR / legal (to support the previous employees). And engineers.
Sales and implementation could maybe be US-based, but then we're flying them around the globe. Not sure that makes sense vs hiring locals.
SMEs, similar story - not always available in the US.
The engineers are the only ones that could realistically be co-located in the US. But, a good chunk of those were acqui-hired, so now you're asking them all to relocate to the US? Not sure that's viable in the best of times, and definitely not in today's ass-backwards political climate.
We should find way to improve the system.
