TN Visa: Working in the US Under USMCA
Read this article in another language: Türkçe
For a Canadian or Mexican professional with the right job offer, TN can be decided the same day — and it carries one trap that surprises almost everyone.
What TN is, and who can use it
TN is the professional work status created by the United States–Mexico–Canada Agreement, the successor to NAFTA. It is available only to citizens of Canada and Mexico. What matters is citizenship, not where you were born — which is why Turkish-origin engineers, accountants, academics and scientists who have naturalised in Canada use TN in full. It is also why TN is not available to someone holding Turkish citizenship alone; for them the E-1 and E-2 treaty visas, H-1B, L-1 and O-1 are the routes to look at.
The profession list is the whole case
TN is not an open work permit. It requires a job offer from a specific US employer for a position that appears on the treaty’s profession list. That list runs to more than sixty occupations — engineers, computer systems analysts, accountants, architects, scientists, university teachers, management consultants, lawyers, pharmacists and registered nurses among the most used. Each occupation carries its own minimum credential: most require a bachelor’s degree, while a few, such as management consultant, accept qualifying experience in the alternative.
The decisive question is never the job title. It is whether the work actually to be performed fits the listed occupation and whether your credentials fit the requirement attached to it. Refusals cluster around exactly this point — a role written loosely enough that the officer cannot map it to the list.
Applying: border, consulate, or USCIS
Canadian citizens are visa-exempt and may request TN directly at a land port of entry or at airport preclearance, presenting the employer’s support letter, degrees and credential evaluations, a résumé and proof of citizenship. A decision usually comes the same day. Mexican citizens first attend a TN visa interview at a US consulate and then enter with that visa. Where you are already in the United States, the employer may instead petition USCIS for a change or extension of status. Which route to take is a strategic decision that should follow the weak points of the file, not habit.
Duration, renewals and family
TN is granted for up to three years at a time. There is no cap on the number of renewals and no annual quota. Spouses and unmarried children under 21 accompany in TD status; TD spouses may enrol in study but may not work. The unwritten condition running through all of it is intent: TN is a nonimmigrant status, and at every entry and every extension you are expected to be able to show that you are not settling permanently.
TN is the fastest work status in North America right up to the moment you decide you want a green card. After that, every border crossing needs a plan.
From TN to a green card: the dual-intent trap
Unlike H-1B and L-1, TN carries no dual-intent protection. A TN holder whose green card process is already under way can run into serious difficulty at a badly timed border crossing or extension. In practice TN holders do move on to permanent residence — through employer sponsorship under PERM and EB-3 or EB-2, or through family routes such as marriage. What matters is that the sequence of steps and the travel around them be planned with counsel rather than discovered at the booth.
If sponsorship is where you are heading, it is worth understanding how that queue works before you start it.
If a green card petition has been filed for you, do not treat the next TN renewal or border crossing as routine. Ask before you travel. The officer is entitled to consider whether you still qualify as a nonimmigrant, and an answer given without preparation is difficult to walk back.
What you should do now
- Map the job to the list first — Before anything else, confirm that the duties — not the title — fit a listed profession and that your credentials meet its requirement.
- Get credential evaluations ready — Degrees earned outside North America usually need an evaluation. Assemble it before you approach the border, not at it.
- Choose the route deliberately — Port of entry, consulate or USCIS petition each suit a different fact pattern. Pick the one that matches your file’s weakest point.
- Plan the green card question early — If permanent residence is the goal, decide the sequencing before the first petition is filed, not after.
- Remember TD spouses cannot work — If household income depends on both spouses, factor that in from the start.
