As per checklist it seems like NOA is a “must document” with others being secondary - T4 , Paystubs and employment letter.
Even I believe I submitted T4 , Paystubs and Latest employment letter.
Most of us that are waiting long time , it seems like we haven’t submitted NOA and instead of asking us , they are directly asking CRA (Canada revenue agency) , which could be taking time .
Once again, I am assuming these things because that’s what common for most of us that are waiting after AOR1 .
really i thought if u r not working then its not mandatory to submit NOA :/.. n cic have asked applicants directly for NOA in the past i didnt know they ask cic directly as well
