Which letter controls if the duties differ?

THE DIRECT ANSWER

Clarify the actual agreed assignment with the employer. Do not simply select the version that appears closest to a TN listing while leaving the real work unresolved.

Explain the source of the difference

Identify whether a document is outdated, abbreviated or describes a different project. Preserve the originals and provide an accurate current account rather than inventing a uniform history.

When the duties described lean toward management, sales engineering, or a hybrid role, ask whether the offer letter can be rewritten to reflect the technical core of the position more accurately, or whether the position genuinely falls outside the profession. Confirm this distinction early with the applicant so expectations about timing and required steps match the actual process rather than assumptions carried over from a Canadian citizen colleague's experience. The job comes second, because the position must correspond to a profession named in the USMCA professional appendix; an inventive job title on an offer letter settles nothing until the duties are matched against a listed occupation. Describe the actual work, qualifications and period of entry requested accurately, and obtain counsel’s review of temporary intent rather than rewriting a continuing job as a fictitious fixed-term contract.
