Not necessarily. Assess the actual practice requirements separately from the TN listing. The immigration qualification should not be described as universal authority to perform every regulated task.
Identify the real duties and condition
Use the actual offer rather than assuming all roles with a similar title involve identical practice obligations. Obtain appropriate advice on the specific issue.
Start with the contracts and proposed duties, then compare each part with the TN requirements: Canadian or Mexican citizenship, a listed profession, its credentials and temporary entry for prearranged professional work. An officer applies the entry as written; there is no general principle that long service in a field cures a credential gap, and arguing that the work is equivalent invites a refusal rather than a discussion. Engineer exists on the list for engineering practice, and is met by a baccalaureate or licenciatura degree or by a state or provincial licence; an officer who reads that entry will apply what it means rather than what it was hoped to mean. The regulation defines the diploma and certificate alternatives, including institution or issuer and country requirements, and the alternative also requires three years of experience.
