Frequently asked questions
Is NOC 84100 eligible for Express Entry?+
NOC 84100 is a TEER 4 occupation. IRCC only counts TEER 0, 1, 2 or 3 work as skilled experience for the Federal Skilled Worker Program and the Canadian Experience Class, so this occupation alone generally won't meet those requirements. Provincial programs may differ.
Is NOC 84100 a high-wage occupation?+
No. NOC 84100 isn't on IRCC's Express Entry high-wage occupations list, so it doesn't earn the extra high-wage or job offer CRS points. Canadian work-length points can still apply for TEER 0–3 work.
Which Express Entry category draws include NOC 84100?+
None of IRCC's current category-based selection lists include NOC 84100. Candidates can still be invited in general, program-specific (such as CEC) or PNP rounds.
