Read the general professional work overview
A La Prairie professional may receive a revised project description after preparing the application documents. Compare the actual new duties with the evidence already collected. An unchanged job title does not establish that the original professional analysis still fits. Put the two descriptions side by side in a table with one row per duty and mark each row unchanged, altered or new. What that produces is usually a short list rather than a rewritten job, and the short list is what the professional analysis has to be tested against.
Compare versions of the assignment
Keep the earlier and current descriptions and identify what changed: the work performed, the employer, the intended duration or the responsibilities. Ask the employer to explain the real assignment. Do not retain an outdated letter because it appears easier to match to a profession. Ask for the change in writing from whoever authorised it, not from the recruiter who relayed it. Project descriptions circulate in several drafts and the version sitting in the applicant's inbox is often not the version the employer approved. Note what disappeared as well: a duty removed can matter as much as one added, because the writing share of the role may have fallen below what the profession describes. Where the employer cannot say who approved the change, that is itself information: an assignment nobody owns tends to change again, and a file built on the current draft will need rebuilding.
Match the profession and qualifications honestly
TN eligibility requires Canadian or Mexican citizenship and a listed profession with its prescribed qualifications. The actual duties matter alongside education and any applicable licensing requirements. Experience is not a universal substitute for a required degree; a degree from an institution outside Canada, Mexico or the United States needs the applicable reliable credential evaluation. Hypothetical example: a medical device instructions-for-use editor is told the assignment now includes reviewing supplier drawings and chairing a change control board; those additions may be reasonable work, and the question is whether what remains still matches the listed profession and its prescribed qualifications. Where an added duty is one a regulator or a client requires a specific qualification to perform, that requirement is the employer's to satisfy and answers the immigration question neither way.
Resolve the change before relying on existing permission
A draft application and a person already working in the United States present different procedural questions. Have the actual status and proposed change assessed before assuming the existing authorization covers it. The employer’s revised project schedule alone does not settle that question. Where the applicant is already in the United States the sequence differs: the question becomes what the existing permission covers and what step, if any, a change of duties requires. Consult counsel before the new duties begin rather than afterwards, and keep the employer's revised description, its date and the name of whoever approved it, since those are the facts any later review will start from.
