For international companies either they import overseas skilled employees to their headquarters (e.g Microsoft) and/or they open up offices in other countries where those skilled employees can work(e.g Google).

There's a pretty good argument for the US to import those skilled employees rather than export those jobs. But as a non US citizen, I'd be more than happy for H1B workers to be more restricted and have more big tech companies open offices in my country.
