That was what i was referring to all along. yes you cannot change it, but one can send wrong documents pertaining to it, that is what i meant there.
And yes, I researched the forum again, multiple NOCs can add up for CRS calculation, so i was wrong there.
But in under FSW you will get points only for primary NOC.
Sometimes i don't know what CIC is playing at, they are so stringent about your NOC matching job duties, if only occupation type matters then why pester us with so much details, just ask us to chose type A.0 or B under which it falls, provide proof of same, it will make life easier for everyone. The way they are going they should simply make it, if you are educated and have decent job, please come to canada, why reject applications based on minor details then. They don't need education to match job, neither single skilled NOC. etc. This system has many loopholes.
As to your problem now, that was what i was asking all along, you have mentioned incorrect details in EE file and received ITA on those. You can send a CSE to ask them to correct your NOC.
