To be clear, H1B isn’t an immigrant visa. It’s a temporary skilled worker visa. There are other visas designed for skilled immigrants. Someone on an H1B isn’t an immigrant so of course the system would be “broken” when expecting H1B to result in a green card. It’s no different than expecting a tourist visa to be the first step to getting a residency visa. H1B was never implemented as a pathway to permanent residency.

Still that aside, great ‘hack’ and congrats on getting your Canadian residency!
