If you’re a citizen of Canada or Mexico working in one of a defined list of professions, the TN visa is usually the fastest, cheapest US work authorization available to you — faster than H-1B, with no annual cap and no lottery. It’s also more limited than it looks: the profession list is fixed, the status is explicitly non-immigrant, and 2026 has brought noticeably tighter scrutiny at renewal. Here’s how it actually works.
What the TN category is
TN (“Trade NAFTA,” a name that stuck after USMCA replaced NAFTA in 2020) is a nonimmigrant work classification created by the trade agreement between the US, Canada, and Mexico. It lets qualifying Canadian and Mexican professionals work for a US employer (or, in limited cases, a foreign employer) without going through the H-1B lottery, the PERM labor certification process, or an annual numerical cap.
Who qualifies
Three things must all be true:
- You’re a citizen of Canada or Mexico — permanent residents of either country (who aren’t citizens) do not qualify for TN status.
- Your job matches one of the ~63 USMCA professional categories — a fixed list carried over unchanged from the original NAFTA agreement, covering roles like engineers, scientists, accountants, teachers, computer systems analysts, management consultants, and healthcare professionals, among others. What matters is whether your actual day-to-day duties match a listed profession, not your job title.
- You hold the credential the category requires — usually a bachelor’s degree, though a few categories accept an equivalent professional license or years of documented experience instead.
There’s no official minimum salary requirement, but your compensation should be broadly in line with what US workers earn in the same role — a below-market offer can itself raise doubts about whether the position is genuinely professional-level. TN status also does not allow self-employment: you need a genuine US (or in some cases Canadian/Mexican) employer offering you the role.
The process differs sharply by nationality
Canadian citizens have the simplest process of any US work classification: no prior USCIS petition is required at all. You can apply directly at a land border port of entry or during airport pre-clearance, presenting your job offer letter, proof of your professional qualification, and evidence of Canadian citizenship. If approved, you receive TN status the same day.
Mexican citizens must apply for an actual TN visa stamp at a US consulate, similar to other nonimmigrant visa categories: complete the DS-160 application, pay the fee, and attend a consular interview presenting the same job offer and credential evidence.
Either way, the employer typically prepares a TN support letter — a detailed letter describing the role, duties, salary, and how they map to a qualifying USMCA category — rather than filing a full Form I-129 petition, which is one of the reasons TN processing is materially faster than H-1B or L-1.
What it costs in 2026
- Canadian citizens at a land port of entry: $80 total — a $50 TN application fee plus the $30 Form I-94 arrival record fee, which rose from $6 in a CBP fee update effective September 30, 2025.
- Mexican citizens applying at a consulate: a $185 MRV (visa application) fee, plus a visa issuance/reciprocity fee that depends on validity — commonly $79 for a 12-month visa or $357 for a 4-year visa, since Mexican nationals can be issued a TN visa document valid for up to four years even though each individual TN admission is still capped at three years.
- If your employer instead files Form I-129 (used for TN extensions/changes processed by USCIS rather than at the border or consulate): the standard $1,385 base filing fee, plus an optional $2,965 premium processing fee for a 15-business-day decision. See our full US visa fee breakdown for how this compares to H-1B and L-1.
Length of stay and renewal
Each TN admission is granted for up to three years and can be renewed in further three-year increments indefinitely, as long as you remain employed in a genuinely TN-eligible role — there is no lifetime cap like H-1B’s six years or L-1’s five-to-seven-year limit. In practice, however, 2026 renewals are seeing closer scrutiny of occupation drift (duties that have quietly shifted away from the original qualifying category) and dual-intent signals — evidence that suggests you’re actually pursuing permanent residence rather than temporary work. Unlike H-1B and L-1, TN status does not carry explicit “dual intent” protection, so pursuing a green card while on TN status is a genuinely more delicate situation and worth discussing with an immigration attorney before you file anything.
Family: the TD category
Spouses and unmarried children under 21 accompany a TN holder on TD status. Unlike an L-2 spouse (who can work incident to status) or some H-4 spouses, TD dependants generally cannot work in the US — this is one of the more significant downsides of the TN route for a dual-income household. See our dependant and family visa guide for how work rights compare across US dependent categories.
TN vs. H-1B vs. L-1
- No cap, no lottery: unlike H-1B, TN has unlimited annual slots and doesn’t depend on winning a random selection.
- No prior foreign employment required: unlike the L-1, which requires a year of employment abroad with a related company, TN just requires a qualifying job offer and profession match.
- Narrower eligibility: TN is restricted to Canadian and Mexican citizens and a fixed profession list — it isn’t a general-purpose skilled-worker visa the way H-1B is.
- Weaker green card bridge: TN carries no explicit dual-intent allowance, while H-1B and L-1 both do — something to weigh carefully if a green card is part of your longer-term plan.
FAQ
Can a TN be denied at the border? Yes — for Canadians applying at a port of entry, a CBP officer can deny entry on the spot if the role, evidence, or profession match isn’t convincing. Bring thorough documentation and expect direct questioning about your specific duties.
Can I switch employers on TN status? Yes, but you need a new TN application (a new support letter and, for Canadians, typically a new border or pre-clearance application) for the new employer — TN status is tied to a specific employer and role, not portable like some other categories.
Can TN lead to a green card? It can, but the path is less direct than H-1B or L-1 since TN doesn’t carry explicit dual-intent protection. Many TN holders eventually transition to H-1B or another status once employer sponsorship for permanent residence begins, rather than filing directly from TN.
Is there a cap on how many times I can renew? No numerical cap exists, but each renewal is assessed on its own merits — a long, unbroken TN history in the same role is generally viewed favorably, while frequent employer changes or apparent title inflation can draw more scrutiny.
This is preparation guidance, not legal advice — TN eligibility depends on fact-specific profession-matching and evidence that shifts case by case, so confirm your situation with your employer’s immigration counsel and the official USCIS TN NAFTA Professionals page before applying.
