IN THIS GUIDE · Match the certificate to the profession named in the Appendix
Start with the TN eligibility and application overview
The Appendix line is the specification
Each listed profession has its own stated qualification: a specific degree for some, a licence for others, and in certain cases a combination of a diploma with several years of experience. The document that decides the case is therefore the one that satisfies that exact line, not the strongest qualification the applicant happens to hold. A postgraduate degree in an adjacent discipline can be less useful than the baccalaureate the Appendix actually names. Read the line first, then check what is in the file against it, and identify any gap while there is still time to obtain an assessment.
The employer letter has to describe the listed work
The letter is the record of prearranged professional employment, and it should describe duties that are recognisably those of the named profession. Where a position mixes professional work with sales, supervision or general operations, the description has to be honest about the mix and clear about why the professional element defines the role. A letter drafted from a generic internal job posting rarely does this well. It should also state the period sought and the terms, and be signed by someone with authority to commit the employer to what it says.
Ownership and self-employment appear in the corporate record
TN does not permit self-employment in the United States, and an applicant with an ownership interest in the U.S. entity is asking a question that the share register answers before anyone speaks. That interest should be disclosed and explained: what the stake is, who controls the entity, who directs the work and who pays for it. In family-owned agricultural and equipment businesses these structures are frequently informal, so the useful preparatory step is to obtain a current, accurate corporate record rather than to rely on anyone's recollection of how the shares were arranged.
Choose the presentation route the file can support
A Canadian citizen may apply at a port of entry or be the beneficiary of an employer's I-129 petition; there is no TN visa stamp issued for Canadians. Port presentation produces a decision on the spot with no chance to supplement a thin file, so it favours a complete, self-explanatory set of documents. An advance petition allows evidence to be assembled and reviewed before travel and suits cases where the credential rule requires explanation. The choice should follow the strength of the record, not habit or the convenience of the start date.
