Start with the TN eligibility and application overview
Read the list entry, not the job title
The U.S. firm calls the position corridor mapping specialist, which appears nowhere on the professional list. That does not matter by itself; what matters is whether the described duties sit inside a listed profession. If the work is boundary retracement, topographic survey, control networks and deliverable plans, Land Surveyor may be the relevant entry. If the position materially combines surveying with structural design or engineering, the application must describe those duties accurately and establish the listed profession and qualification rule on which TN classification is sought. The employer should not delete real duties merely to force the position into one entry.
Provincial licence and U.S. practice are two questions
A New Brunswick commission proves the credential the listing accepts. It does not authorize professional practice in a U.S. state, and no immigration status does. Where a state reserves signing and sealing to its own licensees, the employer letter should say who will sign and seal the work and describe the applicant's role in terms that are lawful for someone without that state licence. Being unable to seal a plat does not defeat a TN application, but an offer letter that promises sealed deliverables from someone who cannot lawfully produce them creates a conflict an officer can see.
Side practice at home, no self-employment there
He runs a small survey practice registered in New Brunswick and expects to keep a few local clients. Continuing that work from Canada is a domestic matter. What TN forbids is self-employment in the United States, so the file should state plainly that the New Brunswick practice will not solicit or perform work there and that he will be paid as an employee of the U.S. firm. If the firm sweetens the package with equity or an option grant, that interest must be disclosed, and a meaningful ownership stake in the petitioning employer can turn the arrangement into self-employment in substance.
Pick the route in, then keep both files identical
A Canadian citizen may request TN admission at a port of entry with the employer's support letter, or the employer may file Form I-129 with USCIS and the applicant enters on the approved classification. No consular visa stamp is issued to Canadians for TN. Whichever route is chosen, the support letter, the résumé, the commission and any professional profile should describe the same duties in the same words. Contradictions between a public profile that advertises design engineering and a letter that describes surveying are noticed, and they are difficult to explain at a counter.
