IN THIS GUIDE · Count a diploma holder’s three years correctly for a Technical Publications Writer TN
Start with the TN eligibility and application overview
Establish when the three years started and ended
The diploma route requires three years of experience related to technical publications writing, documented with dates. The USMCA text does not say that the experience must post-date the diploma, so qualifying work before and after the credential may be counted. Periods of freelance work can be supported with contracts, invoices and business records showing the dates and technical-writing duties. A gap does not erase earlier experience but contributes no months of work. Build a table listing employer or client, dates, title and a one-line duty summary, then total the qualifying periods; anything short of thirty-six months should not be rounded up.
Get letters that describe the work, not just the title
Each experience letter should be on the employer’s letterhead, signed by a person who can verify the facts, and state the start and end dates, the position and the duties performed. The duties must be recognizably technical writing: documenting software behaviour, producing installation and reference guides, maintaining documentation in a versioning system. A letter that says only that she was a valued content specialist leaves the profession unproven. Where a former employer has closed, a contract, pay stubs and a colleague’s declaration can substitute, with an explanation of why the primary letter is unavailable.
Make the U.S. offer match the listing
The offer letter from the U.S. firm should identify the position as Technical Publications Writer, describe the documentation projects, state the salary, start date and an intended duration of up to three years, and confirm that she will be its employee. Content marketing, social media copy or sales enablement writing should not appear as principal duties, because they are not the profession listed. She holds no shares in the firm, so self-employment is not in issue. The letter and her letters of experience together answer the regulation’s questions; the diploma answers the credential half.
What usually goes wrong at the port of entry
Potential defects in a diploma-route file include evidence that does not total thirty-six months of related experience, records that omit dates, and a U.S. job description that drifts into marketing. Experience should not be excluded merely because it predates the diploma; the question is whether it is related and adequately documented. Canadians may apply to CBP at a port of entry or preclearance, paying the admission fee, or a U.S. employer may file Form I-129 with USCIS. No visa stamp is ordinarily needed. Bring the qualifying diploma, transcript, experience evidence and current fee information for the chosen route.
A useful pre-filing review is a two-column comparison: on one side, every listed qualification and principal duty; on the other, the exact exhibit that proves it. If the offer calls the role technical writing but assigns campaign copy as the main work, revise the factual record before choosing a filing route. The review should also confirm that the worker will be an employee rather than the owner of the U.S. operation.
