Read the general professional work overview
Hypothetical example: a West Kelowna civil engineering technologist with a two-year diploma and twelve years on municipal water projects is offered a US position supervising pipeline inspection. The employer's draft letter calls him an engineer. The TN list treats Engineer and Scientific Technician/Technologist as different professions with different qualification rules, and his diploma fits only one of them. Choosing the right entry, and then assembling the documents that entry actually requires, decides the case before anyone reaches the border.
Match the diploma to the entry that accepts it
The Engineer entry requires a baccalaureate degree or a state or provincial licence; a diploma does not satisfy it, and experience cannot be substituted. The Scientific Technician/Technologist entry instead requires theoretical knowledge in a listed discipline, including engineering, and the ability to solve practical problems in that discipline, while working in direct support of professionals in it. The technologist's diploma and transcript, showing engineering coursework, address the theoretical-knowledge element; his project history addresses the practical-problem element. The employer's letter must then confirm the third element by naming the licensed engineers he will support and describing the supervisory relationship. Presenting him as an engineer would invite refusal on the qualification alone.
Rewrite the employer letter around the correct duties
The employer's draft, which calls the position a field engineer and describes independent design sign-off, would undermine a technologist application because it implies work the entry does not cover and that his credential does not support. The revised letter should describe inspection scheduling, data collection, interpretation of results within established engineering parameters, and reporting to the firm's professional engineers, who retain design authority. It should state the position, salary, duration of up to three years and the intention to employ him as an employee. Where the applicant will supervise inspectors, that is compatible with the entry as long as the technical judgement remains within the support role. The letter and his résumé should use the same vocabulary.
Assemble proof for each element, then check the ownership question
The file for the port of entry contains his passport as proof of Canadian citizenship, the diploma and transcript, the employer's revised letter, a résumé listing projects and the engineers he supported, and, helpfully, a letter from a professional engineer he has worked under confirming the nature of that support. If his provincial technologist certification exists, include it; it is not required by the entry but corroborates the discipline. Finally he should confirm he holds no ownership or control in the US employer, since TN excludes self-employment, and should not sign any partnership or profit-share arrangement offered as a sweetener without immigration review. With those pieces, the application stands on the correct entry with the documents that entry demands.
