TN status for Canadian and Mexican professionals under USMCA, which replaced NAFTA on 1 July 2020: who qualifies, the support letter, renewals, intent.

TN is the professional work category available to citizens of Canada and Mexico who have a job offer from a United States employer in a listed profession. It was created by the North American Free Trade Agreement and it continues, unchanged in name, under the United States-Mexico-Canada Agreement, which replaced NAFTA on 1 July 2020.
People still search for the "NAFTA visa," and searching for it is not a mistake. It is the same category. The letters TN come from "Trade NAFTA," the agreement behind them was renegotiated, and the immigration category survived the renegotiation with its structure intact: the same list of professions, the same three-year admission increments, the same absence of a numerical cap. As of September 2026, nothing about USMCA has changed the answer to the question most people are actually asking, which is whether a Canadian engineer or a Mexican accountant can still work in the United States on this basis. They can.
What did change is the paperwork you should be reading. The professions are now set out in Chapter 16 and its appendix of USMCA rather than in Appendix 1603.D.1 of NAFTA. If a recruiter or an online form hands you a document that cites NAFTA by article number, it is not necessarily wrong on substance, but it is out of date on citation, and that is worth noticing before you rely on the rest of it.
Three things have to be true at the same time: you are a citizen of Canada or Mexico, you have an offer of employment from a United States employer in one of the professions on the USMCA list, and you hold the specific degree or credential that the list assigns to that profession.
Citizenship is literal. Permanent residence in Canada or Mexico does not qualify anyone. A Canadian permanent resident who is a citizen of India applies as a citizen of India, in whatever category fits, and TN is not one of them. This is the single most common misunderstanding we correct in a first consultation, and it is not a technicality that a good letter can work around.
The employment must be with a United States entity. TN allows you to work for a US employer or, in some arrangements, for a foreign employer through a US contract, but it does not authorise self-employment. If you own the company that is offering you the job, expect the officer at the border to say so before you finish the sentence.
The credential has to match. Most listed professions require a baccalaureate or licenciatura degree; a few accept a specified alternative. Management Consultant, for example, may be established by a baccalaureate degree or by five years of experience in consulting or in the field of specialisation. If your degree is foreign, a credential evaluation belongs in the packet, not in a promise to provide one later.
The list is closed. A job does not become eligible for TN by being professional, skilled, well paid or hard to fill; it is eligible only if the profession itself appears in the USMCA professional appendix, and the position matches the definition given there.
Professions that are unambiguously on the list include Accountant, Engineer, Management Consultant, and the scientist categories, which cover disciplines such as biology, chemistry and geology. Physician appears on the list, but with a restriction that surprises people every year: the TN Physician category covers teaching and research, not primary patient care. The full appendix is longer than this article, and the only version worth relying on is the current text of the USMCA appendix itself rather than a summary reproduced on a recruiting site.
Two consequences follow, and both come up in real cases. First, a role that mixes duties can be refused because the officer reads the job as something other than the listed profession, no matter what the job title says. A position titled "Engineer" that is described as a sales role is a sales role. Second, the definition attached to each profession, including the degree it demands, governs. A software developer is often admitted as a Computer Systems Analyst when the duties genuinely are systems analysis, and refused when the letter describes coding to specification. Write the letter for the listed profession, or choose a different category.
The employer support letter is the centre of gravity of a TN application. There is no petition, no adjudication in advance, and in the Canadian case no filing at all — the officer decides on the documents in front of them, and the letter is the document that either establishes eligibility in a few minutes or fails to.
A letter that works establishes four things. It identifies the profession from the USMCA list by name and states that the position requires a person in that profession, which is a statement about the job rather than about you. It describes the duties in enough detail that the professional character is visible without the reader inferring it. It gives the duration of the engagement, stated as a definite period rather than as ongoing employment. And it sets out the arrangements for payment: who pays, on what basis, at what rate.
Three habits sink otherwise good letters. Marketing language about the company instead of a description of the work. A duration written as "permanent," which reads directly against the temporary nature of the status. And a set of duties copied from a job posting that was written to attract applicants rather than to describe a profession. We rewrite more TN letters than we draft from scratch, and the rewrite is usually subtraction.
Alongside the letter, bring proof of citizenship, the degree or licence itself, a credential evaluation for a foreign degree, and any professional licence the state of employment requires. If the position is in Florida and the profession is licensed here, the licence question will come up.
This is the procedural split that shapes everything else. Canadian citizens generally do not need a visa and may apply for TN admission directly at a Class A port of entry or at a United States pre-clearance facility in Canada. Mexican citizens generally obtain a TN visa at a United States consulate first, then seek admission at the border with that visa.
The practical consequence for a Canadian applicant is speed and risk in the same package. The decision happens in a single conversation, usually the same day, with no filing fee for a petition because there is no petition. It also happens with no second reader, no request for evidence and no realistic appeal. A refusal at the port of entry is not a denial you respond to on paper; it is a refusal you either cure with better documents on a later attempt or work around by changing category.
The practical consequence for a Mexican applicant is the opposite trade. The consular stage adds a DS-160, an appointment, an interview and waiting time, and the wait depends on the post rather than on your file. What it buys is a documented adjudication before you travel, and a visa in the passport that supports repeated entries during its validity. Current appointment waits vary by consulate; check the specific post rather than an average, and confirm the wait at the specific post before you plan a start date around one.
TN is granted in increments of up to three years, and there is no statutory limit on the number of renewals. This is unusual: H-1B carries a six-year ceiling, and L-1 carries five or seven depending on the subcategory, while TN can in principle be renewed indefinitely as long as the underlying job and the temporary purpose remain genuine.
There are two ways to renew. A Canadian or Mexican national already outside the United States, or willing to travel, may apply again at the port of entry or consulate with a fresh support letter and receive a new admission period. Alternatively, the employer files Form I-129 with USCIS to extend the stay without departure, paying the fee set in the USCIS Fee Schedule in force on the filing date. Form I-129 is also the route for someone already inside the United States in another status who wants to change to TN.
The indefinite renewal is where the category quietly turns on people. Each renewal is a fresh assessment of temporary intent, and the tenth year of a "temporary" assignment is a harder conversation than the second. Officers do ask what the plan is. There is no rule that ten years of TN is too many, and there is also no rule preventing an officer from concluding, on year ten, that the purpose is no longer temporary.
TN requires nonimmigrant intent, and that requirement is not softened by the fact that renewals are unlimited. You must intend to depart when the authorised stay ends. Filing an immigrant petition on your behalf, or filing an adjustment of status application, is evidence that you intend to remain permanently, and it can cost you the next renewal or the next entry.
Compare this with the categories the site covers elsewhere. H-1B specialty occupation status and L-1 intracompany transfer status are dual intent by law: an approved immigrant petition does not, by itself, damage an H-1B extension or an L-1 entry. TN has no such protection. The same green card step that is harmless for a colleague on H-1B is a live problem for you.
This does not mean a TN holder can never pursue permanent residence. It means the sequence matters, and the sequence has to be planned before the first immigrant filing rather than after a refusal at the border. In practice the plan is usually one of three things: move to a dual intent category before the immigrant petition is filed, time the permanent process so the applicant is not relying on TN entries while it is pending, or accept consular processing abroad with clear eyes about the interval without status. Which of these fits depends on the profession, the employer and the priority date, and it is the conversation to have first, not last. Our overview of employment-based immigration sets out the permanent options; the EB-2 national interest waiver and the O-1 extraordinary ability category are the two that most often change the sequencing for a TN professional, because neither requires the employer to start the process.
The spouse and unmarried children under 21 of a TN principal are admitted in TD status, for the same period granted to the principal. TD does not carry work authorisation, and there is no application that creates one. A TD spouse cannot file Form I-765 on the basis of TD status.
Say this plainly to the family before the move, because it is the point that most often turns a good offer into a bad year. A TD spouse may study, may hold a Social Security number only if separately eligible, and may not take a job in the United States, paid or unpaid, on that status. A spouse who intends to work needs their own basis: their own TN if they are a Canadian or Mexican citizen in a listed profession, an H-1B, or another category entirely. Our page on nonimmigrant status services covers the switch, and it is worth settling before the family books a flight.
TD dependents follow the principal in both directions. If the TN ends, TD ends with it. If the principal changes to another status, the dependents need a corresponding change filed for them, and it does not happen automatically.
TN stops fitting for three reasons in practice: the profession is not on the list, the role has grown into something the listed definition no longer describes, or the person now wants permanent residence and the nonimmigrant intent requirement has become the obstacle rather than a formality.
The usual destinations are H-1B for a specialty occupation with a degree requirement, L-1 for a transfer from a related company abroad, O-1 for demonstrated extraordinary ability, or a permanent employment-based route. Each has costs that TN does not: H-1B has a cap and a registration season, L-1 requires a qualifying corporate relationship and a year of prior employment abroad, and the permanent routes take years rather than an afternoon at the border.
We work with Canadian and Mexican professionals relocating to South Florida and with the employers here who hire them, from our Coral Springs and Hallandale Beach offices. Florida draws a particular slice of this population — engineers into construction and infrastructure, accountants into cross-border practices, scientists into research institutions, healthcare professionals into a system that is licensed at the state level. The licensing question is the one that most often needs answering before the border question, and it is worth raising at the intake stage rather than the week before the flight.
Yes, under a different agreement and the same name. The category is TN, it was created by NAFTA, and it continues under the United States-Mexico-Canada Agreement, which replaced NAFTA on 1 July 2020. The professions are now listed in the USMCA appendix rather than in NAFTA Appendix 1603.D.1.
No. TN requires citizenship of Canada or Mexico. Permanent residence in either country does not qualify anyone, regardless of how long they have lived there or where the job offer comes from.
No. The USMCA professional list is closed, and a position qualifies only if the profession appears there and the duties match the definition given for it. A job that is skilled, well paid or hard to fill does not become TN-eligible on those grounds.
Generally yes. Canadian citizens may apply for TN admission at a Class A port of entry or at a United States pre-clearance facility, presenting proof of citizenship, the employer support letter and their credentials. Mexican citizens generally obtain a TN visa at a United States consulate first.
Not without planning the sequence first. TN requires nonimmigrant intent, and an immigrant petition or adjustment of status application filed on your behalf can create a problem at the next renewal or entry in a way it would not for H-1B or L-1, which are dual intent by law.
No. TD carries no work authorisation and no way to apply for one. A spouse who wants to work in the United States needs an independent basis, such as their own TN, an H-1B, or another category that permits employment.
TN is granted in increments of up to three years, and there is no numerical limit on renewals. Renewal is either a new application at the port of entry or consulate, or Form I-129 filed with USCIS by the employer.
