FBI says North Korea deployed thousands of IT workers to get remote jobs in US with fake IDs::North Koreans are using fake IDs and learning IT skills to sneak their way into remote American jobs, according to the FBI and Justice departments.
Only if they worked physically in the US. these people work offshore for US companies.
I’m guessing here but based on how I’ve done international contracts… The US-based company pays the not us-based company, and that not US-based company pays the employees. The not US-based company is responsible for ensuring that the employee can legally work in the country that they are physically in. And since that country is not America, they don’t need an American green card.
