I'm considering applying for Express Entry (EE) under the Federal Skilled Worker (FSW) program, and I also want to apply for various Express Entry Provincial Nominee Program (PNP) streams. For my EE profile, I plan to select NOC 20010 (Engineering Manager), and for the PNP streams, I'll go with NOC 21301 (Mechanical Engineer). Choosing NOC 20010 will make me eligible for STEM, and NOC 21301 has a good chance of getting PNP nominations. My question is, is it allowed to have different NOCs for EE and PNP? I have overlapping duties from both NOC codes, and my employer reference letter will reflect this.
