A private testing charge is not an immigration authorization.
Identify the purpose of the fee before paying
Review the actual employer or provider terms and distinguish them from official charges and credential-evaluation costs. No fee should be presented as a guarantee that the listed profession’s requirements will be satisfied.
Ask for an itemized invoice showing who charges the assessment fee, what service it purchases, whether it is refundable, and whether the employer or applicant is contractually responsible. Compare that private amount with credential-evaluation expenses and any official government charge applicable to the chosen procedure; current official fees should be confirmed from the USCIS schedule or relevant agency instructions. Payment cannot establish Canadian or Mexican citizenship, placement in a listed USMCA profession, the profession’s required qualification, or a genuine prearranged job. TN also cannot be used for self-employment. Canadians may generally apply for admission at a port of entry, while an employer may sometimes file I-129. The dangerous shortcut is paying a recruiter who implies that its test fee guarantees status or permits work.
Hypothetical example: An environmental scientist in Saint-Charles-de-Bourget receives three separate requests: a laboratory assessment charge, a foreign-degree evaluation invoice, and a quoted immigration preparation cost. He identifies the recipient and deliverable for each before paying, verifies which government fees genuinely apply, and keeps receipts without calling them approvals. Even if the private laboratory confirms his technical skills, he still prepares citizenship, profession, qualification, and employer evidence for the actual TN decision.
