Prepare the consulting or services agreement, incorporation records for the Canadian company, ownership and director details for any US entity involved, and a letter from the US client describing the professional duties, period, and payment arrangement.

Reviewers need to trace the flow of work and payment. Include the signed or draft agreement with schedules, any statement of work, and evidence of the applicant's credentials for the specific profession claimed. Where a US affiliate is involved, add its share register and any documents showing voting control. Note verbal understandings that are not in writing, because those often carry the facts that matter.
Bring the employer's support letter, citizenship proof, the qualifying degree or licence with any evaluation or translation, and evidence of the current relationship with the employer. Identify the actual responsibilities, employer, remuneration and duration; a relocation package does not turn unrelated duties into qualifying professional work. 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. Add the offer letter or contract showing salary and duration, and a short résumé that matches the dates in everything else.
