Read the general professional work overview
A Vaudreuil-sur-le-Lac applicant may work for one employer while supporting two departments. Explain the work in both settings rather than submitting one department’s description as though it covers the entire assignment. The first review should produce a responsibility map with one line for each department, the actual employer, the supervisor, the location, and the professional output. Hypothetical example: A wildlife toxicology analyst is offered a single TN role split between a laboratory and a compliance unit. The decision is whether the combined duties remain professional work within the selected TN occupation, or whether a material part of the assignment belongs to another role.
Prepare a responsibility map by department
Identify the projects, expected outputs and person assigning work in each department. Where the same responsibility appears twice, explain whether it is one shared task or two different activities. Do not inflate professional duties by counting the same work twice or leave an unrelated assignment out because it complicates the explanation. Ask each department to confirm the percentage of time, the deliverables, and whether another team can reassign the work. The packet should reconcile differing titles rather than treating them as harmless shorthand. That mapping gives the employer a concrete choice: narrow the assignment to its actual professional core, or obtain advice on a route that fits the broader work.
Connect the combined work to the TN profession
The applicant must be a Canadian or Mexican citizen qualified for a listed profession, and the actual temporary work must fit that profession. A degree or an internal job classification alone does not establish the fit. Ask the employer to explain any difference between the two department descriptions using the real proposed duties. Assemble the offer, duty map, credential records, and any required licence evidence in the same sequence a reviewer will use. A Canadian applicant can request a TN decision from CBP when seeking admission, while a U.S. employer may use the USCIS petition process where appropriate. The chosen process does not remove the need to show that the actual temporary assignment fits the listed profession.
Identify the legal employer behind the department names
Two business labels may belong to one entity or to separate entities; preserve the actual arrangement for process advice. Do not infer authorization for another employer from a shared brand. TN prohibits services to a U.S. entity solely owned or controlled by the applicant. Resolve the employer and duty questions before treating the packet as complete. Obtain the agreement that explains which entity hires, pays, supervises, and may end the assignment. If a client directs important work, identify that fact instead of using a brand name to hide it. The decision is whether the proposed arrangement is a qualifying employer-directed professional engagement; TN does not permit self-employment for services provided to an enterprise the applicant owns or controls.
