IN THIS GUIDE · A pharmacist told to mention her employer's permanent-residence plan at the border
Start with the TN eligibility and application overview
Temporary entry is a condition of the category, not a formality
TN is not one of the categories that tolerate a declared intention to remain. The applicant has to satisfy the officer that she is seeking temporary entry and will depart when the authorized period ends, and that question is asked at every crossing, not only at the first. A permanent-residence plan is not automatically fatal, and an employer is entitled to have one; what defeats an application is an applicant who cannot say how long the assignment runs, what she returns to, or who volunteers at the counter that the move is meant to be final. The practical handling is to keep the two processes on separate paper and separate timetables, to answer the intent question with the facts of the assignment rather than with a recruiter's script, and to obtain advice before a permanent filing is made while a TN is being relied upon.
The status is tied to one described job, and to somebody else's direction
Admission is granted for a period not exceeding three years and is tied to the employment described in the file. Two consequences follow that are easy to overlook. The first is that a change in who employs her, or a material change in what she does, calls for a fresh assessment rather than a longer stay, and adding a second American employer is a new application rather than a note to an existing one. The second is that she may not, once inside, work for herself. TN does not permit self-employment in the United States, and the boundary is drawn by who directs and pays for the work rather than by what an agreement is called. Any ownership interest she holds in the American entity should be disclosed with its percentage and examined before travel, because an arrangement in which she is in substance her own employer aims directly at the one thing this category forbids.
Where she presents the file, and what an employer petition would change
A Canadian citizen may present a TN application in person at a land port of entry or at a preclearance facility inside Canada, and does not need to obtain a visa first. The alternative is for the employer to file Form I-129 with USCIS and for her to present the approval at the border, which suits organizations that want a decision on paper before they commit to a start date, and which leaves a record that can be pointed to later. A Mexican citizen doing the same job would ordinarily use the visa process at a consular post instead. The route differs; the occupational test behind it does not. Whichever route is chosen, the supporting letter has to come from the employer that will direct the work and has to describe a professional position rather than a headcount slot.
Reading Appendix 2 literally, one profession at a time
Appendix 2 is a list, not a description of skilled work in general, and each entry carries its own qualification rule. Pharmacist accepts a baccalaureate degree or a state or provincial licence. Medical Laboratory Technologist accepts a degree, or a post-secondary diploma or certificate together with three years of experience. Social Worker accepts a baccalaureate degree and nothing else. Some entries also limit what the person may be coming to do, so meeting the credential rule is not always the end of the analysis. An occupation absent from the list cannot be reached by choosing the nearest listed title, and the trades are absent entirely. Delphine's file should therefore quote the entry by name, show how she meets that entry's rule specifically, and describe duties that plainly belong to it. Where an American employer has invented a title such as clinical operations lead, the letter should translate that title back into the listed profession and the work it actually involves.
