Read the general professional work overview
Hypothetical example: Jonah is a Canadian citizen and a geologist with a Logan Lake exploration-services contractor, offered a resource-modelling position with a U.S. mining company. The Geologist profession in USMCA Appendix 2 requires a baccalaureate or licenciatura degree, so his university records are the deciding documents and his provincial registration is supporting evidence. TN requires prearranged professional work and does not permit U.S. self-employment; any ownership interest must be disclosed and assessed. A Canadian may apply at a port of entry or preclearance, or through an employer-filed Form I-129, without a TN visa stamp. TD dependants may study but may not work.
Lead with the degree the profession actually names
The Geologist entry accepts a baccalaureate or licenciatura degree, without a licence alternative. Jonah's core document is therefore his degree certificate with an official transcript, not his P.Geo. registration. If his degree is in earth sciences or geological engineering rather than geology by name, the transcript should show geology coursework and, if there is doubt, a short statement from the university or a credential evaluation confirming the field. Registration is useful because it shows recognized standing and helps the officer accept that the degree is relevant, but it does not replace the degree and should be presented second. A degree from outside Canada, Mexico or the United States needs an equivalency evaluation from a recognized service.
Make the employer letter describe professional geology
The position must require a geologist. A letter that reads as sample logging, core handling and field supervision invites a finding that the job is technical rather than professional. The U.S. employer should describe the work in the terms a geologist would recognize: interpretation of drilling data, three-dimensional resource modelling, geological mapping and reporting that informs mine planning. The letter must also state the title as it appears in the profession list, the salary, the intended period up to three years, that the employment is temporary, and that Jonah is a Canadian citizen. It should come from the employer that will pay him. If the Logan Lake contractor is placing him under a services agreement, the letter comes from the contractor and attaches that agreement.
Assemble the packet and choose the filing route
Jonah carries his passport and proof of citizenship, the employer letter, degree and transcript, registration certificate, credential evaluation if any, and a resume. He may apply at a port of entry or preclearance location, paying the fees on the USCIS schedule, and if admitted may start immediately. Alternatively the employer files Form I-129 in advance; the approval notice then accompanies him to the border. A refusal at the port is not a bar to reapplying with corrected documents, but it is recorded, so a first attempt with a weak letter is costly. His family may accompany him in TD status, may study, and may not work. He should keep his Logan Lake employment until he is admitted.
