Have you not provide the t4 and pay stubs before?How did you find out? Not NOC mismatch exactly, the officer wasn't convinced that I have 1 year of Canadian Work Experience (which was wrong evaluation on his part, according to the job letter I had more than 1.5 yr experience at the time of my application)
and also he wasn't satisfied with the job letter provided by my employer. ( However, the 1st officer was satisfied with the job letter)
I got a new employment letter with more details that would clear all the doubts and submitted it for reconsideration along with paystubs and T4's for last two years.
