The geologist listing specifies a baccalaureate or licenciatura degree. Experience may help explain the applicant’s work but is not a universal replacement for that credential.
Assess the qualification with the actual duties
Provide the degree and relevant records, and describe the field and analytical work the applicant would perform. Do not assume the title geologist establishes either the credential or the profession fit. Canadian or Mexican citizenship, prearranged qualifying activities and temporary entry remain separate requirements even when the employer values the applicant’s experience.
Engineer requires a baccalaureate or licence; Scientific Technician/Technologist requires theoretical knowledge of a discipline and the ability to solve practical problems, with the work performed in direct support of a professional in that field. If the diploma-and-experience branch applies, the work is heavier: letters from previous employers describing management responsibilities, dates of employment, and enough detail to show that the roles were management in hotel or restaurant operations rather than supervisory work in an adjacent field. A spouse who wants an income has to qualify independently: a college instructor spouse could hold a second TN with a second offer letter, and other listed professions such as accountant, registered nurse or physiotherapist each carry their own credential rule.
