While TEER 4 occupations are typically excluded from the Federal Skilled Worker Program (FSWP) under Express Entry, candidates working under NOC 84101 have viable pathways to Canadian permanent residency. Key programs include the Atlantic Immigration Program (AIP), the Rural and Northern Immigration Pilot (RNIP), and specific Provincial Nominee Program (PNP) streams targeting semi-skilled energy sector workers. Eligibility for these pathways generally requires a valid job offer, secondary school education, and language proficiency equivalent to at least CLB 4.
