Read the general professional work overview
Hypothetical example: a Champlain medical laboratory technologist holds a three-year college diploma rather than a bachelor's degree and has an offer from a U.S. hospital laboratory. Medical Laboratory Technologist is listed for TN with two routes: a baccalaureate, or a post-secondary diploma or certificate plus three years of experience. Her case rests on three documents, the diploma with its transcript, a dated experience record confirmed by employers, and the hospital's letter, and each must meet a definition rather than a general impression.
The diploma must meet the regulation's definition, not just be called one
The TN rule defines a post-secondary diploma as a credential issued after at least two years of post-secondary education at an accredited academic institution in Canada or the United States. A three-year college program in medical laboratory technology fits that definition; a short certificate from a private training provider may not. Present the diploma as issued, the transcript showing the program length and the institution's accreditation, and a certified English translation. Do not describe the diploma as equivalent to a degree, because the officer is not looking for a degree on this route; he is looking for a defined diploma plus experience.
The experience record must add up to three years of the profession
The second element is three years of experience in the profession, and the officer will want to see it counted. Prepare a dated table of each employer, the position, the start and end dates, and whether the work was full time, then obtain a letter from each employer confirming those facts on letterhead. Experience during the diploma program, unpaid placements and work in a different role in the same laboratory do not count in the same way, so identify them honestly rather than folding them in. If a former employer has closed, a record of employment or a colleague's statement may help, but say what each source actually knows. Three years and one month is the target, not two years and a promise.
The hospital letter must describe a technologist's job and the credential route claimed
The letter from the U.S. hospital should name the employer and worksite, describe the laboratory duties in terms that match Medical Laboratory Technologist, state the period requested up to three years and the salary, and say which credential route is being relied on. Confirming Canadian citizenship with the passport is the applicant's task. If the hospital or the state requires its own laboratory personnel licence or certification, that is a professional requirement separate from TN and should be arranged with the hospital before the start date. Present the package at a port of entry, or have the hospital file Form I-129 in advance; either way the three documents do the work.
