Not as a general rule. Apply the actual profession’s prescribed qualifications and permitted alternatives. Praise or experience does not create an unlisted exception.
Use the reference for observed facts
A supervisor can describe genuine work without deciding the legal credential standard. Keep the document’s claims within its actual basis.
Once the entry is fixed, the qualification is established by a specific record: a baccalaureate or licenciatura degree, or a state or provincial licence, or in some entries a defined combination of a diploma and years of experience. The credential requirement is decided by the appendix entry, so read that entry literally: if it calls for a baccalaureate degree the transcript and parchment matter, and if it calls for provincial licensure the regulator's letter matters. Several entries accept a post-secondary diploma or certificate together with three years of experience, one accepts five years of experience in the field as an alternative to a degree, and others, including Engineer, name a degree or a licence and stop there. Eligibility turns on Canadian or Mexican citizenship, which permanent residence alone does not satisfy, a qualifying listed profession with its credential requirements, prearranged professional work in the United States, and temporary entry.
