On that note, I also did not understand the post about H1B workers. Ostensibly a primary reason for the existence of the visa category in their first place is to fulfill the need for foreign talent that needs to be PRESENT in the US.
It is about being present in the office. As opposed to working from home, as in a house in the US.
But if the work can be done fully remote, why does the person need a visum to be in the US? Why not work remote from abroad without visa requirements and probably with lower cost of living?
