The complete actual role must be assessed against the proposed listed profession; the number of tasks alone does not answer the question.
Explain how the work fits together
Provide the substantive responsibilities rather than a collection of labels. Do not combine unrelated duties under a profession without analysis. Hypothetical example: a Canadian forensic entomologist is asked to support a U.S.
laboratory after a flood, while the proposed letter also mentions client training and equipment installation. The first review should separate the scientific analysis from every ancillary activity, identify the closest listed profession, and test the credential rule against the person’s degree and transcript. The occupation title chosen by the employer is not the deciding record.
A detailed duty chart, signed offer, curriculum vitae, diploma, transcript, and any required professional licence usually settle the important comparison. Put the percentage of time beside each material duty instead of using broad verbs such as ‘advise’ or ‘coordinate.’ If a qualification alternative is claimed, show why the alternative applies rather than treating related experience as interchangeable with a stated education requirement. The sequence matters: define the real assignment, choose the profession only after that definition, then collect records that support both.
A weak file often starts with a preferred category and edits the job around it; that approach can leave inconsistent descriptions in the offer, customer statement, and résumé. Where duties are mixed, the applicant should obtain a narrower confirmed scope or seek individual advice before travel. TN is for qualifying temporary professional work and cannot cure a mismatch between actual services and the listed category.
