Read the general professional work overview
An offer may have been written before the employer settled the production schedule. If the applicant would now spend substantial time covering line duties, obtain that revised account before relying on an earlier professional description. The issue is the actual proposed work, not whether the old document remains signed.
Compare the original and revised work allocation
Hypothetical example: an engineering offer describes design validation, but a later shift plan assigns regular machine operation while a vacancy remains open. Keep both records. Ask who approved the change, how long it is intended to last and what the applicant would do each week. A temporary staffing explanation does not by itself decide whether the whole position qualifies.
Identify the qualification independently of the schedule
TN requires Canadian or Mexican citizenship, qualifying prearranged professional activities and temporary entry. For engineer, the listed qualification is a baccalaureate or licenciatura degree, or a state or provincial licence. Determine which alternative the applicant actually meets. That credential does not make every task in an engineering department professional engineering, or waive a destination state’s practice requirements.
Make the evidence agree with the intended arrangement
Have the responsible employer explain genuine revisions rather than removing inconvenient duties from the file. Foreign degrees from institutions outside Canada, Mexico and the United States require a reliable credentials evaluation. Foreign-language documents submitted to USCIS require complete certified English translations. Keep those tasks separate from correcting an inaccurate work description; neither translation nor evaluation resolves a changed job.
