Short answer
Under 8 CFR 214.6(d)(3)(ii), the documentation for a TN applicant “shall fully affirm” five items: the profession, a description of the professional activities, the anticipated length of stay, the educational qualifications or appropriate credentials, and the arrangements for remuneration. Paste a letter into the checker below and it reports whether each item is mentioned, shows the text it matched, and gives a general tip for each item. Source: 8 CFR 214.6(d)(3).
Check a letter
Paste the full text of the employer support letter. The check runs in your browser: nothing you paste is stored or sent to TNPath. How TNPath checks its own guides and letters is set out at how TNPath checks its information.
The five items, in the regulation’s words
8 CFR 214.6(d)(3)(ii) says the documentation “shall fully affirm”:
- (A) The profession: “The profession of the applicant under Appendix 2 to Annex 16-A of Chapter 16 of the USMCA.”
- (B) The activities: “A description of the professional activities, including a brief summary of daily job duties, if appropriate, in which the applicant will engage in for the United States employer/entity.”
- (C) The length of stay: “The anticipated length of stay.”
- (D) The credentials: “The educational qualifications or appropriate credentials which demonstrate that the Canadian or Mexican citizen has professional level status.”
- (E) The remuneration: “The arrangements for remuneration for services to be rendered.”
The checker looks for mentions of each item and shows the matched text, so you can read it in context.
How the check works
- Pattern matching only. The checker looks for the listed profession names, duties wording and action verbs, stay and date wording, credential terms, and pay wording or a dollar amount. It does not read for meaning.
- A mention is not coverage. A letter can mention an item in a way that does not cover it — for example, naming a profession the duties do not match. Read each matched excerpt in context.
- Nothing leaves the page. The pasted text stays in your browser’s memory for the check and is gone when you close the page.

Common questions
What does this checker look for?
It looks for mentions of the five items that 8 CFR 214.6(d)(3)(ii) says the documentation shall fully affirm: (A) the profession of the applicant under Appendix 2 to Annex 16-A of Chapter 16 of the USMCA; (B) a description of the professional activities, including a brief summary of daily job duties, if appropriate; (C) the anticipated length of stay; (D) the educational qualifications or appropriate credentials which demonstrate professional level status; and (E) the arrangements for remuneration for services to be rendered. For each item it reports “found” or “not found” and shows the text it matched.
Is my letter sent anywhere or saved?
No. The check runs in your browser. The pasted text is read from the box on this page, checked in memory, and never stored or sent to TNPath. The only counts this page reports are the site’s ordinary anonymous action counts — fixed event names with a fixed page label — and they contain nothing from your letter.
If all five items are found, is my letter complete?
This checker reports mentions only. It does not assess eligibility or whether the content is sufficient. A letter can mention an item in a way that does not cover it, and an officer reads the whole letter and the documents that accompany it. Your employer must review the final letter, confirm every statement in it, and sign it.
What should I do if an item is not found?
Read the tip under that item: it describes what the item usually contains, with the regulation’s wording. Then ask the employer to review the letter and, where the employer confirms the detail applies, add it in the employer’s own words. Every statement in the letter must be accurate for the real job.
Who decides whether a letter is accepted?
For a Canadian applying in person, a U.S. Customs and Border Protection officer decides at the port of entry or preclearance station. This checker is a reading aid only and plays no part in that decision.
