A TN evidence file should reflect the complete proposed job. Before preparing the final employer explanation, identify operational responsibilities and contingencies that may affect whether the work fits a listed profession. Hypothetical example: an industrial ecologist receives an offer whose short title is “environmental specialist,” while the attached schedule includes procurement and sales tasks. The applicant must decide whether the complete assignment fits a listed TN profession before collecting documents that merely repeat the title. A sound file is assembled around facts, not a preferred label. The final decision should be recorded in writing: which profession is proposed, which document proves each qualification, and which party controls the actual work. That short audit prevents a later letter from drifting beyond the reviewed facts.
Read beyond the title and first paragraph
Hypothetical example: a technical offer includes design work but also requires routine production coverage during absences. Mark that obligation and ask the employer how it will operate in practice. Do not delete material duties from the immigration description merely because they complicate the proposed profession analysis. Create a responsibility table that identifies recurring, occasional, and contingency duties, plus the person who supervises each. The decision is whether the nonprofessional duties are incidental or substantial enough to alter the analysis. Keep the employer explanation aligned with the actual agreement; deleting awkward facts is more dangerous than explaining them accurately.
Connect the real duties and exact qualifications
Identify the listed TN profession and its specific requirements, including permitted credential alternatives where applicable. Match those requirements with genuine documents. Eligible Canadian or Mexican citizenship is also required; Canadian permanent residence does not substitute for it. Experience or an employer’s preference does not universally replace a prescribed qualification. For every qualification, identify the document that settles it: passport for citizenship, diploma and transcript for education, licence for regulated practice, or an appropriate credential evaluation where needed. If the occupation has a specific alternative, test that alternative directly. Do not assume a broad professional history fills a prescribed credential requirement.
Reconcile the documents before relying on them
Compare the actual offer, support letter and relevant employment or customer terms. Disclose ownership interests for individual review rather than assuming a blanket result. If the substantive role changes, reassess it. A signed contract proves what the parties agreed, not that the applicant already has permission to perform every contemplated U.S. activity. Verify the legal employer and project source before drafting. If an intermediary or customer is involved, collect documents showing the employer-directed professional assignment, duration, and payment arrangement. TN is temporary professional employment and cannot be used for an applicant’s self-directed U.S. enterprise. Decide whether the final facts support an entry request or an I-129 petition process before travel is booked.
