The setting and title are insufficient. The actual professional duties and listed degree need to support the category.
Explain the scientific responsibility
Describe the biochemical question, methods and conclusions the applicant develops. Identify other work honestly instead of treating all laboratory activity as equivalent. Canadian or Mexican citizenship and the complete temporary professional arrangement remain necessary.
TN eligibility for a biologist generally rests on a qualifying baccalaureate or licenciatura degree; an adjacent-field degree requires assessment of its actual coursework against the profession rather than an assumed blanket exception, so compare the applicant's actual degree and area of study against that standard. A process engineer's TN eligibility rests on three separate things lining up: a listed Appendix 2 profession, that profession's own credential rule, and duties that actually match the entry's definition. The candidate should collect the diploma, transcripts, licence records, and any needed credential evaluation before travel, then ask the employer to describe the prearranged duties independently of its skills test. Officers compare the duties described against the listed profession, and a letter about brand standards, revenue targets and cross-property projects can read as a general management job rather than hotel management.
