TN Visa Categories: Eligible Professions and Credential Rules

The TN visa’s eligible professions are the roughly 63 occupations listed in Appendix 1603.D.1 of the USMCA (which replaced NAFTA but kept this classification intact), grouped into General, Medical/Allied, Scientist, and Teacher categories.¹ Only Canadian and Mexican citizens can use TN status, the job offer must come from a U.S. employer (self-employment does not qualify), and your credentials have to match the specific profession you’re applying under. If your occupation isn’t on the list, no amount of experience or education makes you eligible.

Teachers

Teachers qualify only if they work at a college, seminary, or university.² K-12 classroom teachers at public or private schools are not on the list and cannot use TN status.

Education and Credential Requirements

Most TN categories require a baccalaureate or licenciatura degree in a field directly related to the profession. The State Department’s Foreign Affairs Manual is blunt: experience generally cannot substitute for the degree.³ A computer science degree will not qualify you for an accountant TN, and a business degree will not qualify you for an engineer TN. The field of study needs to match the profession.

A handful of categories accept a post-secondary diploma or certificate combined with three years of relevant work experience instead of a full degree. These include computer systems analyst, graphic designer, hotel manager, industrial designer, interior designer, technical publications writer, and medical laboratory technologist. A “post-secondary diploma” in this context means a credential issued after at least two years of study at an accredited institution.

Engineers have their own alternative: a state or provincial license can substitute for the degree requirement.⁴ A licensed Professional Engineer in Ontario, for example, could qualify even without a bachelor’s degree in engineering.

If your degree comes from an institution outside the United States, Canada, or Mexico, you’ll need a formal credential evaluation from a service that specializes in foreign educational credentials. USCIS requires this evaluation to accompany the original diploma or certificate.⁵

Many professions also carry state licensing requirements that operate on top of the TN eligibility rules. Nurses, pharmacists, engineers, and other regulated workers must hold the appropriate license for the state where the work will be performed.

Professions With Special Rules

Several categories have qualification rules that diverge sharply from the standard “degree plus job offer” path. Overlooking these details is where applications fall apart.

Physicians

Physicians face the most restrictive rules of any TN profession. They can only engage in teaching or research. Direct patient care is not allowed. If a physician’s role involves some patient contact, it must be incidental to the teaching or research work. USCIS evaluates this by looking at how much time the physician spends with patients relative to teaching, whether the physician maintains a regular patient load, and whether the physician receives separate compensation for clinical work.⁴ A physician hired primarily to see patients in a clinic cannot use TN status, even if the employer labels the position as “teaching.”

Management Consultants

Management consultants can qualify with either a baccalaureate degree or five years of professional consulting experience, or a combination of the two. This category gets heavy scrutiny because it’s often used as a catch-all. The work must be genuinely consultative, meaning temporary, periodic, or project-based. A management consultant who fills a permanent operational role at a company is not performing consulting services, and the application will likely be denied. Management consultants employed directly by the company receiving their services must fill a temporary, extra-staffing position, not step into an existing role or a newly created permanent one.

Scientific Technicians and Technologists

This category does not require a degree at all. Applicants must show theoretical knowledge in a qualifying scientific field (agricultural sciences, astronomy, biology, chemistry, engineering, forestry, geology, geophysics, meteorology, or physics), typically demonstrated by at least two years of relevant post-secondary education. The catch: a scientific technician must work under the direct supervision of a professional in the same field. The employer’s support letter needs to explain exactly how the supervising professional will manage and review the technician’s work.⁴

Disaster Relief Insurance Claims Adjusters

One of the more unusual categories. To qualify, the applicant needs either a bachelor’s degree or three years of claims adjustment experience, plus completion of relevant training in disaster relief claims. On top of that, the application must be tied to a qualifying disaster event, typically a presidentially declared disaster or an event assigned a catastrophe serial number by the Property Claims Service. General insurance adjusters do not qualify; the work has to involve an actual disaster.

Self-Employment Is Not Eligible

This trips up applicants more often than almost anything else. TN status requires a prearranged job with a U.S. employer, and self-employment is categorically prohibited.⁶

USCIS defines self-employment broadly. If you’re the sole or controlling shareholder of the company offering you the job, you’re self-employed in their eyes, even if the company is a separate legal corporation. Setting up a U.S. entity specifically to sponsor your own TN is exactly the kind of arrangement USCIS watches for. Warning signs include incorporating a business in which you’ll be the primary worker, or advertising services for a company you control. Canadian or Mexican citizens who want to run their own business in the U.S. need to look at E-1 (Treaty Trader) or E-2 (Treaty Investor) status instead.⁶

Proving You Qualify

Once you’ve matched yourself to a profession on the list and confirmed your credentials fit, the application itself rests on a few core documents. Every TN filing needs the same basics, whether you present them at the border or at a consulate:

A valid Canadian or Mexican passport as proof of citizenship.
Your original degree, diploma, or certificate, along with official transcripts. If the education was completed outside the U.S., Canada, or Mexico, include a credential evaluation.
An employer support letter (the most important document in the package). It must identify the specific TN profession you’ll work in, describe your job duties in detail, state the anticipated start and end dates, and specify your salary and any additional compensation.¹
A professional license, if the profession or the state where you’ll work requires one.

The employer support letter deserves special attention because it is where eligibility is either proved or lost. A vague job description is one of the fastest ways to get denied. The letter should connect your specific duties to the TN profession so clearly that an immigration officer doesn’t have to guess. If the role involves a supervisory relationship (as with scientific technicians), the letter should spell out who supervises whom and how. And because TN status is not dual-intent, the position must have a foreseeable end date; a job description that reads as permanent undercuts the temporary nature the classification requires.⁶
