Start with the TN eligibility and application overview
Start with the proposed position
Map the US role line by line against the relevant USMCA profession. The position title is less important than the duties, the employer’s need, and the stated qualification. If the role combines several jobs, explain which professional work is genuinely being offered and avoid padding the description with unrelated responsibilities.
Check the applicant’s eligibility
Canadian or Mexican citizenship is required; permanent residence in Canada alone is insufficient. Match the applicant’s degree, licence, or other listed credential to the occupation’s rule. Where an education history is not straightforward, collect transcripts and credential analysis early rather than assuming experience can replace a required degree.
Keep employer and applicant separate
The US enterprise must be receiving the applicant’s professional services through a genuine employment or qualifying contractual arrangement. An applicant cannot use TN to become their own US employer. Ownership, voting control, invoicing, supervision, and the right to end the engagement all deserve careful review.
Choose a workable sequence
A support letter should identify the employer, professional capacity, purpose, period, pay terms, and qualifications. Put travel, onboarding, and client commitments after the applicable immigration step. A later extension is a fresh compliance exercise, so keep the underlying records available rather than relying only on the original submission.
