Full comparison for Canadian and Mexican professionals — plus the complete USMCA TN occupation list, conversion guide, and the green card trap you must understand before choosing TN.
The TN visa (Trade NAFTA) — now governed by the United States-Mexico-Canada Agreement (USMCA) — is one of the most underutilized and misunderstood US work visas available. For eligible Canadian and Mexican professionals, the TN can offer same-day work authorization with no lottery, no per-country backlog, and no annual cap. Yet for many professionals, the H-1B remains the better long-term choice.
According to USCIS TN visa guidance, TN status is available for Canadian and Mexican citizens who work in one of approximately 63 USMCA-listed professional categories. The key distinction from H1B: TN is strictly non-immigrant, meaning it does not permit dual intent and is ill-suited for those pursuing permanent residence.
This guide covers the 12-factor comparison table, the TN-to-H1B conversion process, why the green card dual-intent restriction matters, and the complete list of TN-eligible professions with real job title examples. Whether you are choosing between TN and H1B for your first US position or considering switching, this resource gives you the data to decide.
| Factor | H-1B | TN (USMCA) |
|---|---|---|
| Citizenship Requirement | Any nationality | Canada or Mexico citizens ONLY |
| Annual Cap / Lottery | 85,000/year cap — lottery required for most | No cap, no lottery — file anytime |
| Occupation Restriction | Any specialty occupation (bachelor's degree field) | Only USMCA-listed occupations (~63 categories) |
| Processing | USCIS petition (weeks to months) | Canadians: same-day at port of entry (CBP). Mexicans: consulate DS-160. |
| Initial Period | 3 years (6 year max, then AC21 extensions) | 3 years (unlimited renewals) |
| Maximum Duration | 6 years (extendable with I-140/PERM) | Unlimited — renew in 3-year increments indefinitely |
| Dual Intent | Yes — explicit dual intent allowed | No — TN holders cannot have immigrant intent (limits green card) |
| Green Card Path | Fully compatible — file PERM/I-140 while on H1B | Very limited — inconsistent adjudication; must show non-immigrant intent |
| Employer Change | H1B transfer (new petition with portability) | Canadian: new CBP entry. Mexican: new DS-160 + consulate. |
| Spouse Work Authorization | H-4 EAD if I-140 approved 365+ days | TD (TN dependent) — no work authorization |
| Filing Fee | $730+ USCIS base + ACWIA + fraud fees | ~$160 CBP fee (Canadian). ~$185 MRV fee + I-129 if via USCIS. |
| Family Members | H-4 status: can accompany, EAD available with I-140 | TD status: can live in US but cannot work |
When TN Beats H1B:
✓ You're Canadian or Mexican and don't want to risk the lottery
✓ Your role is on the TN occupation list
✓ You don't plan to pursue a green card anytime soon
When H1B Beats TN:
✓ You want a green card path (H1B → PERM → green card)
✓ Your occupation isn't on the TN list
✓ You're not a Canadian or Mexican citizen
✓ Your spouse needs work authorization (H-4 EAD vs TD no-work)
Many Canadian and Mexican professionals start their US careers on TN and later need to switch to H1B — typically when they decide to pursue permanent residence, when their employer's legal team recommends H1B for stability, or when they marry a spouse who needs work authorization. The transition is straightforward but timing is everything.
Secure an H1B Sponsor
Find a US employer willing to file an H1B cap-subject petition. TN holders are fully eligible to be sponsored for H1B — your TN status has no bearing on H1B eligibility.
Register in H1B Lottery (March)
Your employer files an H1B electronic registration in March. In FY2026, USCIS received over 470,000 registrations for 85,000 slots — odds are roughly 20–25% for regular cap.
Employer Files Full H1B Petition (April–June)
If selected in the lottery, your employer files the full I-129 petition with the LCA, support letter, and all documentation. Premium processing ($2,805) gets a decision in 15 business days.
H1B Approved — Start Date October 1
Cap-subject H1B approvals are effective October 1. You can continue working on TN through September 30 without interruption — maintain valid TN status until H1B is effective.
Change of Status vs. Consular Processing
If you're in the US, USCIS grants Change of Status from TN to H1B automatically. If abroad, get H1B stamp at a US consulate. Either path works — CoS is simpler if you're already in the US.
Begin Green Card Process on H1B
Now on H1B with dual intent, your employer can start PERM labor certification, file I-140, and pursue permanent residence — all of which were blocked by TN status.
The biggest misunderstanding about TN visa is that many professionals believe they can pursue a green card while on TN. The reality is more complex — and failing to understand the dual intent problem can derail both your green card application and your TN status simultaneously.
The Core Problem: Non-Immigrant Intent Requirement
TN visa holders must demonstrate non-immigrant intent — the intention to depart the US when their TN status ends. Filing for a green card (immigrant intent) directly contradicts this. CBP officers and consular officers can deny TN entry or renewal if they believe you intend to immigrate.
• Filing I-485 (Adjustment of Status) while on TN
• Having an active I-140 immigrant petition
• Employer filing PERM labor certification on your behalf
• Self-petitioning for EB-1A or EB-2 NIW
• Statements about long-term US residency plans at port of entry
• Simultaneously hold H1B and file for green card
• I-140 approval does not affect H1B status
• Pending I-485 does not make H1B invalid
• Travel internationally with approved H1B stamp
• Spouse gets H-4 EAD work authorization
The practical advice from most immigration attorneys: use TN for the first few years while establishing your career in the US, then switch to H1B as soon as you decide you want a green card. The switch can be done without leaving the US (Change of Status). Once on H1B, you gain explicit dual intent protection under INA §214(h), and your green card pursuit is fully legal and transparent.

The USMCA Appendix 2 lists approximately 63 professional categories eligible for TN status. Below are the 20 most commonly used categories, with real-world job title examples that have been approved by CBP. Note that job titles must match the TN category — "Software Developer" is not a listed TN category, but "Computer Systems Analyst" is, and many software roles qualify under that designation with the right employer support letter.
