Leaving H1B to chase a PR that "might" come - especially when most of these folks are working for large, established companies with affordable COL and good careers. I was still expecting this program to be filled within hours tbh.It is very probable.
Just checked... 10k is like what 1-2% of the total number of h1b holders? So even though not a lot of people are inclined to move from the US to Canada right now, 10k applicants is nothing.
