First, your answer has nothing to do with my question to xbonez about why, despite his being stuck in the US H-1B morass, he did not mention planning to take up this offer.
Second, your supposition of my under/overestimation has nothing to do with the factual composition of FAANG and other US tech companies' Canadian offices. As I said, they are a) mostly people who cannot and will not ever get US visas (i.e., those who didn't make the first hurdle that xbonez was lucky enough to cross), and b) a few native Canadians who for one reason or another don't want to move to the US.
