Hello, looking for your help with my situation. I got my AOR recently, however, during the course of my application I noticed that I picked the wrong NOC code. I'm sending a cover letter and a new reference letter from my employer correcting the NOC code. My question is, the duties and responsibilities on my new reference letter don't match the entire list from the new NOC ( 2 or 3 off), will adding an additional duty on my new revised letter cause any issues?? Both noc codes share most of my duties and responsibilities. I'm only changing NOCs because one requires certification that I don't have. Please help.
