Identify the actual contracting employer
Ask which entity will sign the offer, direct the work and pay the compensation. Record any staffing or customer relationship. Different entities under one brand can have different roles; describe those roles using the agreements instead of treating the logo as evidence of a single employer. Separate the employer’s commercial description from the treaty profession. A task inventory, reporting line and proposed supervision often reveal whether the position is genuinely professional. The useful first-review output is a one-page comparison showing each duty against the profession selected.
Keep professional fit at the centre
Compare the complete duties with a listed USMCA profession and its specific qualification requirements. A restructuring does not resolve a mismatch in credentials or duties. TN requires eligible Canadian or Mexican citizenship; Canadian permanent residence is a separate status. Check credentials before booking travel. A transcript, degree, licence, or properly explained experience record must support the precise listed requirement. If an evaluation is needed, compare its conclusion with the actual credential rather than treating its existence as a result.
Explain the change in the file
Preserve the original offer as historical evidence and obtain a current, accurate explanation of the change. Reconcile the employer name across the support letter and other submitted material. Do not silently alter a previously signed document to make the record look unchanged. Set the employer’s documents in a practical order: legal identity, support letter, duties, compensation, duration, and authority of the signer. A letter prepared from an old template can create a mismatch that no passport or résumé resolves.
Confirm permission for the intended work
Check the applicable petition or admission procedure and the applicant’s current status, if any. A Canadian citizen may seek TN classification at a port of entry, or a U.S. employer may file Form I-129; a Canadian generally does not require a TN visa stamp. U.S. self-employment is not permitted, ownership stakes must be disclosed, and sole or controlling ownership of the U.S. entity receiving the services is prohibited. Resolve the authorization question before commencing work for the new entity. Treat a later change in worksite, manager, duties, or corporate employer as a new fact to assess. Keep the original representation and the updated record together. Starting a different role first and explaining later can make the classification difficult to defend.
