To the ones who got REJECTED on the grounds that the offer of employment seem to be temporary and seasonal (even in my case given I have an LMO, have been working in the same position for almost two years with still almost 1 year to go on LMO):
>>> kind fellow folks on this forum reached out, repeating the offer of employment has to have it written that they are willing to keep us even after the PR comes through, for an indeterminate future <<<
The magic words, and I agree with them. My employer stated that he supports my PR, said lots of nice things about my work, however missed to say he'd want to keep me after the PR comes through.
As far as I'm informed CIC does not re open rejected cases. Cancelled might get lucky, however not all.
Good luck and success to all.
