I don't think 2171 is included in the LIST, I am afraid your application can be rejected if you apply on the base of NOC 2171
Yes but when they sent me the docs for correction, shouldn't they mention anything about NOC 2171 (if this was incorrect). The instruction that was send to me said, "please correct the highlighted field in page 2 (where i forgot to write N/A) and send it back to NS".
Other than that all other fields in the applications had a red check mark including my job duties and responsibilities.
So unless i get it back again, i guess 2171 was OK.
I will update, if i get something.
