Read the general professional work overview
Hypothetical example: Kwame is a mechanical engineer at a Bradford West Gwillimbury food-equipment manufacturer. His engineering degree was awarded outside North America, and what he relies on professionally in Ontario is his provincial licence rather than the diploma. A U.S. employer wants him under TN. The Engineer entry on the USMCA professional list can be satisfied by a baccalaureate degree or by a state or provincial licence, and which of those a file rests on changes the documents it needs.
Decide which branch of the credential rule the file uses
The profession's own credential rule is the starting point for any TN file, and for Engineer the rule offers two routes: a baccalaureate or licenciatura degree, or a state or provincial licence. Kwame could try either, and the choice is strategic rather than cosmetic. A degree awarded outside Canada, Mexico or the United States will generally require an evaluation establishing its equivalence, which takes time and introduces a third party's opinion into the file. A current provincial licence, by contrast, is a single official document issued by a body that has already made that assessment. Where both exist, presenting the licence as the primary basis and the degree as supporting background is often the simpler file, though a licensed adviser should decide what fits the actual facts.
Confirm the licence is current, in the right name, and verifiable
A licence carries weight because it can be checked, which means the details have to match everything else in the file. Common problems are mundane: a licence in a maiden name while the passport shows a married name, a certificate that lapsed during a period of parental leave, or a class of registration that does not authorize independent practice. Obtain a current letter of good standing from the regulator rather than relying on a wall certificate, and check that the discipline recorded matches the work the U.S. employer has described. If the licence has any restriction attached to it, that restriction should be disclosed and explained rather than discovered by someone else.
Make the job description match the profession, not the industry
The second half of the file is the employer's letter, and food-equipment manufacturers tend to write job descriptions in the language of their own product line. A letter that describes machine build supervision, customer installations and shop-floor troubleshooting may accurately describe the work while saying nothing about engineering as a profession. The letter should state that the position is a professional engineering position, describe the engineering activities involved, name the profession being claimed, and confirm that the employment is prearranged with the U.S. employer. Because TN cannot be used for self-employment, any ownership stake Kwame would hold in the hiring company must be disclosed and considered.
