Describe the actual proposal and distinguish agreed responsibilities from speculative future work. Do not omit a known material part of the intended role.
Keep the scope documents dated
Provide the current agreement and relevant amendments. The reviewer should be able to tell what is planned now and what would require a later decision.
Once the job is described truthfully, the letter should state the employer's name and address, the professional title and duties, the period requested up to three years, the salary and how any variable pay works, and the statement that the applicant holds the required degree. A letter on company letterhead identifying the United States employer, naming the listed profession, describing the duties in that profession's terms, and stating the temporary duration, the salary and the work location. The employer must produce a letter that names the profession and describes the real duties, which often takes several drafts because human-resources staff write job descriptions for recruiting, not for immigration. Build the TN file from authentic records: a signed offer or contract, an employer letter describing the actual professional services, proof of Canadian or Mexican citizenship, and evidence meeting the selected USMCA profession’s qualifications. The set needed is the duty letter describing the actual proposed work, confirmation of the offer terms, and current credential evidence for the new role, refreshed rather than reused since licensing or professional registration details can differ by state or by role.
