^I think I have a similar concern..
Guys, after I received ITA, I read online that changing NOC code is fine so long as I provide an explanation in my LOE. I have done just that but now that I'm reading more into it, I'm growing more concerned. I checked my EE application again and I have 3 previous jobs listed with the old NOC code and my PR application was submitted with the new NOC code (although with an explanation in LOE). My application is already nearing the 6 month estimate. Should I be concerned about this ? If this was grounds for disqualification, I probably would have already been rejected, right?
