A credential assessment is distinct from any required practice licence and the actual immigration permission.
Track the separate conditions
Identify which steps remain for the proposed work. Do not use the report’s completion date as an automatic authorized start date or a guarantee that every professional requirement has been met.
Create three parallel timelines: completion of the foreign-credential review, satisfaction of any practice-licence condition, and acquisition of TN classification for the job. Confirm the licensing sequence, employer start date, and room for correcting discrepancies. The route is restricted to citizens of Canada or Mexico who have prearranged professional employment, meet the particular qualification for a USMCA-listed occupation, and will not be self-employed in the United States. A Canadian may apply at a port of entry or have the employer submit Form I-129; the evaluator's delivery date cannot establish status. The usual mistake is resigning or promising services when only the education comparison is finished.
Hypothetical example: an Orford land surveyor receives a positive assessment of a Romanian degree days before a proposed project launch. The report may support the education element, yet it does not resolve a required surveying licence, the fit between field duties and the Land Surveyor profession, or immigration admission. He should obtain the regulator's written requirements, align the support letter and start date, and choose the entry or petition process before travelling to work. Proof of Canadian permanent residence without citizenship would stop the TN sequence entirely, so nationality belongs at the beginning of the calendar.
