The duties must be assessed as a whole against the listed profession. A professional credential and an accounting title do not automatically make a mixed commercial role qualifying.
Describe what occupies the working week
Ask the employer to distinguish accounting analysis and reporting from selling, lead generation and general account management. Provide the expected time allocation and actual deliverables. Where a temporary sales duty is planned, record its duration and why it exists. Do not solve the mismatch by deleting duties from a support letter while leaving the real work unchanged.
For TN, establish Canadian or Mexican citizenship, a listed professional role, the matching qualifications, a real prearranged engagement, and a temporary purpose. A Canadian applicant may seek classification during entry inspection or use the employer-petition route; the choice changes the sequence but not the governing facts. The arrangement cannot amount to the applicant running their own U.S. employment through an entity they control. Hypothetical example: a structural-drafting coordinator is offered a role called engineering specialist, but the schedule includes procurement negotiation for half the week. The first review compares the written outputs, supervision, and allocation of hours with the selected listed profession. If the commercial work is central, changing the title will not solve the mismatch. The decision is whether the employer can offer a genuinely professional assignment or whether the candidate should not use TN for this job.
Before the chosen process begins, put that conclusion beside the supporting record and reconcile any conflict in the offer, scope of work, or ownership papers. A persuasive plan cannot substitute for the fact those records establish.
