Explain a professional schedule spanning Canada and the United States

Hypothetical example: a Sault Ste. Marie applicant with work in both countries should document the actual employment and US activities. A hybrid schedule is not itself an immigration category. TN preparation must establish the listed profession, specific qualifications and eligible Canadian or Mexican citizenship. The document decision is to prove one actual US professional engagement, rather than to collect every record associated with a cross-border life. Confirm the applicant's eligible citizenship, the listed profession, qualifications, US employer, duties, duration, and compensation. TN cannot be used for a substantively self-employed US arrangement. Hypothetical example: A prosthetics-and-orthotics clinician is asked to visit a US rehabilitation practice twice a month. She chooses between rescheduling the visits and preparing the proper TN record after comparing the employer's duties letter, her qualification evidence, and the actual worksite plan. Before presenting the file, make one final decision: does every document describe the same employer-directed professional service, or has the arrangement drifted toward independent activity? Resolve drift in the underlying agreement before using it as TN evidence. Keep the finished packet narrow and internally consistent. The best final check asks whether the support letter, credential documents, citizenship proof, and travel plan could all be read together without suggesting a different US role or an independent enterprise. If one document points elsewhere, resolve it before the proposed professional activity starts.
