Shady. The worst ive seen is forcing your American staff to hire a massive overseas team at approx $10k per employee per year, having them set up a local company in their country with the understanding that it's just a front and you are their only client, force them to work during American hours and forcing all of your American employees to remote train them for two years and then firing your American staff. Had this happen to me once.
But they wore lots hats. I worried it was a way to get H1B visas for software dev roles.
