Assess the actual engagement and activities rather than reach a conclusion from the onboarding label.
Read the early schedule in the context of the real job
Explain what the person is hired to do and what the first weeks involve. Do not invent a universal permitted onboarding percentage or use a professional title to hide a different substantive position.
Begin with the signed offer, a detailed duty breakdown, and the exact USMCA profession claimed. TN eligibility requires Canadian or Mexican citizenship, prearranged professional-level business activity for a U.S. or foreign employer, and the listed profession’s particular education, licence, or experience rule; Canadian permanent residence is not citizenship. Compare onboarding tasks with the position after orientation, identify who directs the work, and disclose any ownership. A common error is assuming that a professional title cures months of routine production. The engagement must remain professional, temporary, and outside prohibited U.S. self-employment; a Canadian may seek admission at a port of entry or use an employer-filed Form I-129.
Hypothetical example: A forester from L’Anse-Saint-Jean is offered prearranged work assessing timber inventories for an unrelated U.S. consulting firm. Her opening calendar includes safety briefings, software access, and field protocols. She should pair that calendar with forestry duties, her citizenship proof, qualifying degree, reporting structure, compensation, and assignment length. If the first month instead consists mainly of operating harvesting equipment, calling it onboarding would not establish professional forester work. The employer should clarify the genuine division before she chooses the port-of-entry route or an I-129 petition.
