Hi, I have the same question. in EE profile i have given My work experience as NOC 2173 software developer but it should have been 2174 for Mainframe developer. Same for my husband i have given NOC 2173 which is incorrect and it has to be 2174 for mainframe developer for first few years and 2172 DBA for the next few years. I have received ITA. Can i change the NOC in PR application and submit with LOE? will it create any problems in my approval process?
