The TN is the classification created by the North American trade agreement for citizens of Canada and Mexico coming to practice, temporarily, one of the professions listed in the agreement itself. There is no annual cap, no lottery and no limit on renewals: as long as there is professional work for a U.S. entity and the stay remains temporary, the status renews, in periods of up to three years.
That combination makes the TN, for someone with the right nationality and the right profession, the fastest work route there is in the United States. And also a route full of literalism: outside the list there is no TN, however strong the résumé.
The list of professions and what it requires
The list incorporated into the regulation has four groups. The general professions, from accountant to urban planner, taking in engineer, lawyer, architect and systems analyst. The health professions, from dentist to registered nurse, with physicians admitted only for teaching and research. The scientists, from agronomist to zoologist. And post-secondary teachers.
The typical requirement is a bachelor's degree, or the Mexican licenciatura, in the field, sometimes with a state or provincial professional license as an alternative. And there are exceptions built into the text itself: a management consultant may qualify on five years of experience, and a scientific technician needs no degree, provided they have theoretical knowledge of one of the ten listed disciplines and work in direct support of a professional in it.
Two reading rules apply throughout. Where a degree is required, experience does not replace it. And the degree need not match the job title exactly, provided there is significant overlap between the education and the work to be done.
The procedure: two countries, two paths
A Canadian needs no visa. They present themselves directly at the port of entry, or at preclearance inside the Canadian airport, and the agreement bars requiring a prior petition or labor certification of them. A petition to USCIS exists as an option, not as the rule. A Mexican needs the TN visa, obtained at the consulate, and presents it at the border.
In both cases the central document is the employer's letter, and the regulation wants it complete: the profession from the list, a description of the activities, the expected duration, your qualifications and the pay arrangement. Degrees obtained outside North America require an equivalency evaluation. There is no prevailing wage to meet in the TN, but the pay must be consistent with professional-level work.
Admission runs up to three years, and renewal has two doors: seeking an extension from USCIS with you already inside the United States, or re-entering at the border with a new letter. The underlying limit is intent. The TN requires entry without the intent of permanent residence, with work that ends at a foreseeable point, and each new entry or extension re-examines that.
What USCIS tightened in 2025
On 4 June 2025 USCIS published the new part of its manual devoted to the TN, and the definitions narrowed. Self-employment has always been barred in this category. The manual now also bars de facto control of the company: it looks at who founded it, who controls it regardless of share percentage, and who receives most of the income, and denies the TN where the company was created to make the applicant's own employment possible.
- An engineer needs a degree in engineering itself, and may not hold computing roles without software or computer engineering credentials.
- Systems analyst does not cover programmers.
- Economist does not cover financial analysts or market researchers.
- A scientific technician may not support patient care, which excludes health technologist roles.
- The job title, the manual says, establishes nothing on its own: what decides is the activity you will actually perform.
The family: TD status
A spouse and unmarried minor children receive TD status for the same period as the professional, with no admission fee and without needing to be Canadian or Mexican. A TD holder may study full time without a student visa, but may not accept employment in the United States. The State Department manual notes the possibility of applying for work authorization, without the sources saying more than that, and neither will we.
Where cases usually fail
- A job with a listed title and unlisted content: programming presented as systems analysis, market research presented as economics.
- A degree outside the required field, or experience offered in place of a mandatory degree.
- A company controlled in fact by the TN applicant, or created to employ them.
- A scientific technician supporting patient care, or with no qualified professional from the ten disciplines to support.
- Failing to satisfy the officer, at the border or the consulate, that the stay ends at a foreseeable point.
- A nurse without the destination state's license and without the required certification.
- Starting work for a new employer before the petition is approved or before a new admission.
- A supervisory role that is merely administrative and does not require the professional knowledge of the listed field.
