Resolve the factual difference with the responsible organizations before relying on either account.
Correct the source of the discrepancy
Keep legitimate versions and explain which duties actually apply. Combining the most favourable sentences into a fictional position would weaken the evidence rather than establish the listed profession.
Set the offer, customer statement, contract, and proposed daily schedule side by side, then mark every discrepancy in occupation, tasks, supervision, worksite, and duration. The responsible signers should correct their own records and explain any legitimate change; the applicant should retain earlier versions rather than splice favourable phrases into a new document. TN eligibility still turns on Canadian or Mexican citizenship, a prearranged engagement in a USMCA-listed profession, and compliance with that listing’s particular qualification rule. Canadian permanent residence alone is not citizenship, and work for a United States business controlled by the applicant would be prohibited self-employment. Once the facts match, Canadians may present at a port of entry or use an employer’s Form I-129 process where appropriate.
Hypothetical example: a North Hatley graphic designer receives an agency offer for interface design, while the customer letter describes advertising sales and account solicitation. Her portfolio does not resolve that contradiction. She should ask both organizations whether design or sales is the genuine assignment, secure corrected signed descriptions, and match her diploma to the selected TN profession. If sales will dominate, presenting only the offer’s design wording would give an inaccurate picture of the job.
