I submitted my PR application a few days ago for me and my spouse. As proof of work, I included my employment letter, last 3 months pay stubs and my T4 for last year. I did not submit my NOA because I think what I had is enough as proof (and NOAs are not mandatory). Can it be a cause for rejection if I don't have my NOA? Should I do a case specific inquiry and submit it separately to CIC? Any input would help for my peace of mind, thanks.
