IN THIS GUIDE · Turning an open-ended, generic employer support letter into an accurate statement of activities, duration and remuneration
Start with the TN eligibility and application overview
Tell the employer what the letter has to establish
Employers often send a general confirmation of employment because nobody explained the purpose. The letter supports a specific listed profession, so it needs the duties that show professional work at that level, the credentials relied on, the employer's identity, the arrangement's expected duration, and how the professional will be paid. Sending the employer a short note describing these elements usually produces a better draft than asking for revisions afterwards. Hypothetical example: A conservator hired by a manuscript-restoration firm has a degree in art conservation, while the offer calls the role an archivist. The decision is whether the listed profession, duties, and credential actually align before the letter is signed.
Replace open-ended wording with the intended period
Distinguish the continuing employment relationship from the temporary period of entry requested. An ongoing job is not itself a permanent-residence plan. Ask the employer to explain the work and intended assignment period accurately, including any renewal provisions, rather than inventing a contract end date or deleting facts that need to be explained. The first review should identify the document that fixes the requested period: an executed engagement, a project schedule, or a confirmed employer instruction. If the record does not settle the date, the letter should say what is known and avoid treating an estimate as a contractual fact.
State remuneration and the working relationship accurately
The letter should show how the professional is engaged and paid, whether as an employee of the US entity or under a services agreement with an identified party. Include the salary or fee arrangement in the terms the parties agreed. If the applicant holds any ownership interest in the entity being served, that should be described accurately rather than left out, since sole or controlling ownership raises a self-employment bar. A review should also identify who directs the work, who bears commercial risk, and which entity receives the services. Those records settle whether the proposed arrangement remains employer-led rather than being described only through a convenient payment label.
Handle longer-term immigration goals openly
Discuss any longer-term immigration plans with counsel before deciding what route fits. The actual intent and intended temporary stay must be described truthfully. Do not conceal material facts or ask the employer to invent a finite employment contract where none exists. At the same time, do not confuse an ongoing position with an intention to establish permanent residence. Decide early whether the immediate objective is a temporary professional assignment or a different immigration strategy. That decision does not justify changing accurate facts; it tells the applicant which genuine records and timing questions must be addressed first.
