My friend has precisely 7 months left on PGWP from tomorrow, if she gets her Nomination in October, which seems most likely from current scenario, she would still have 2 months before WP expiry to apply for PR. And if we apply the next day of getting nomination
Well, unless there is a draw the day after you get the nomination, that is not feasible. But CIC appears to make about 2 draws a month, so unless something changes, the longest you would have to wait for a draw would be ~ 2 weeks.
are two months enough for Paper application to pass initial review so that we could apply BOWP on that basis?
"Maybe" - it all depends what is going on with IRCC at the time...
