Short answer
A TN support letter for a technical publications writer is written by the U.S. employer and should cover the TN profession, the job’s professional activities, the length of stay, your credentials and your pay. For this category, the duties should describe technical documentation — manuals, guides and specifications — and this sample shows the diploma-plus-experience route. Source: 8 CFR 214.6(d)(3), USCIS Policy Manual.
What a technical publications writer letter must contain
No government form exists for the letter. Under 8 CFR 214.6(d)(3)(ii), the documentation for a Canadian applicant should describe the profession, the professional activities with a summary of daily duties, the anticipated length of stay, the applicant’s educational qualifications or credentials, and the arrangements for pay. For Technical Publications Writer, three details deserve extra care:
- The list entry, quoted exactly: “Baccalaureate or Licenciatura Degree; or Post-Secondary Diploma or Post-Secondary Certificate, and three years experience.”
- The credential route you actually use. Either a degree, or a post-secondary diploma or certificate plus three years of experience. This sample shows the diploma route, so the qualifications paragraph names the diploma, its school and year, and the years of experience in technical writing. The TN list defines a post-secondary diploma as a credential issued on completion of two or more years of post-secondary study.
- Duties that describe technical documentation. Writing and revising manuals, guides and specifications, working with subject-matter experts and testing documentation against the product read as the profession. Marketing copywriting and sales writing are different kinds of writing.

- Organize and maintain document libraries and version control.
- Develop illustrations and diagrams supporting the text.

The TN list of professions (Appendix 2 to Annex 16-A of the USMCA, set out in 8 CFR 214.6(c)) states the minimum requirement for Technical Publications Writer as: “Baccalaureate or Licenciatura Degree; or Post-Secondary Diploma or Post-Secondary Certificate, and three years experience.”

What each numbered part is doing
- The Re: block names the applicant, “citizen of Canada”, the TN profession exactly as it appears on the list (“Technical Publications Writer”), the job title and the requested dates.
- The request connects the employer, the applicant, the TN profession and the position in one sentence.
- About the Company says what the employer does, in its own words, and where it is.
- The position and duties carry the case. Every duty describes technical documentation work: writing and revising manuals, guides and specifications, verifying content with engineers and subject-matter experts, maintaining document libraries, and updating publications as products change. None of them is marketing or sales writing.
- The minimum requirement quotes the list entry word for word, including the degree alternative.
- Qualifications state the credentials the applicant actually holds: the post-secondary diploma, with its school and year, and six years of experience in technical writing, matching the documents they bring.
- Length of stay says the job is temporary and gives dates, up to three years.
- Remuneration states pay, hours and the U.S. payroll.

Common technical publications writer letter mistakes
- Marketing or sales writing duties. Marketing copy, advertising copy, sales writing, social media content, blog content and press releases read as marketing or general content work rather than professional technical writing. If the real job is writing of that kind, consider an independent review by a U.S. immigration lawyer.
- Mixing the credential routes. The diploma route pairs a post-secondary diploma — two or more years of post-secondary study — with three years of experience in technical writing. Presenting a diploma without the experience, or a shorter program as a diploma, leaves the route the letter names undocumented.
- A title that points elsewhere. Titles such as Copywriter, Marketing Writer, Content Writer and Blogger can describe marketing or general content work rather than the Technical Publications Writer profession. Keep the real title, and make sure the duties honestly describe what you do.
- Documentation duties with no product. Duties that never name what is being documented — the manuals, guides, specifications or products — don’t show technical publications work. Name the publications and how you verify them.
- No dates or pay. A letter without a period of stay or pay arrangements leaves out elements the regulation describes, and officers focus on a clearly temporary stay with defined dates.
Never add or inflate duties to fit a category. Every line should be something your employer will confirm and you can describe in your own words at the border.

Common questions
Is there an official TN support letter for technical publications writers?
No. There’s no government form. The regulation, 8 CFR 214.6(d)(3), describes what the employer’s letter should cover, and the sample on this page is one way to lay it out.
What are the two credential routes?
A Baccalaureate or Licenciatura Degree; or a post-secondary diploma plus three years of experience. The diploma must have required two or more years of post-secondary study. (The list also names a Post-Secondary Certificate, which its definitions describe as a Mexican credential.)
What kind of writing does this letter describe?
Technical documentation: manuals, guides, specifications and other technical publications. Marketing copywriting and sales writing are different kinds of writing, so describe the technical documentation you actually produce. TNPath does not decide whether a particular job fits the category.
Who signs the letter?
Someone at the U.S. employer with authority who knows the role, such as the hiring manager or an HR representative, on company letterhead.
Will TNPath tell me whether I qualify?
No. TNPath is a document-assembly tool. It organizes the facts you provide into templates and gives general information. It doesn’t make eligibility determinations or recommend case-specific strategy. Only U.S. Customs and Border Protection decides whether to admit you.
