No. Assess the actual activity instead of deciding solely from the absence of wages.
Describe what will be performed
An interview discussion and productive work can involve different facts. Do not assume an employer’s informal invitation establishes permission to carry out the proposed tasks.
What matters is whether the duties actually performed still match a listed profession and remain professional in character, and whether the employer and the prearranged position are still as described. Identify any evaluation or professional licensing issue separately instead of assuming the job title settles both immigration and practice requirements. The Scientific Technician or Technologist entry asks instead for theoretical knowledge of a listed discipline together with work in direct support of a professional in that discipline, which is a statement about the receiving employer as much as about the applicant. The offer must involve prearranged work in a profession on the USMCA list, and the applicant must meet that profession's specific qualification and citizenship requirements; a title alone does not establish either. The applicant and employer should check the responsible state board's requirements for sealing drawings or taking responsible charge of designs, including any examination, experience or comity rules. Canadian or Mexican citizenship, qualifying prearranged professional work and temporary entry remain separate TN requirements, and destination practice permission must also be addressed.
