The TN visa under USMCA (formerly NAFTA) lets Canadian and Mexican professionals work in the US in specific occupations. Renewal at the border is fast and cheap, if you know exactly what you need. Here's the full playbook.
The TN (Trade NAFTA, now under USMCA) nonimmigrant status allows citizens of Canada and Mexico to work in the US in one of 63 designated professional occupations listed in USMCA Appendix 2. The TN is granted in 3-year increments with unlimited renewals.
| Feature | Canadian Citizens | Mexican Citizens |
|---|---|---|
| Application Method | Directly at port of entry (CBP) OR I-129 with USCIS | US consulate visa application, then CBP entry |
| Visa Stamp Required | No (I-94 serves as proof) | Yes (TN visa stamp in passport) |
| Duration | Up to 3 years per admission | Up to 3 years per visa/admission |
| Filing Fee (Border) | ~$56 CBP inspection fee | Consulate fee varies |
| Spouses | TD status (no work authorization) | TD status (no work authorization) |
Preparing a clean, organized package dramatically increases approval speed at the port of entry. Here's exactly what to bring:
CBP officer scans your passport and asks the purpose of your visit. State you're applying for TN status.
TN applications are always processed in secondary inspection. Don't be alarmed, this is standard.
Officer reviews your documents, may ask questions about your duties, employer, salary, and qualifications. Be prepared to explain your job clearly.
Officer approves or denies. If approved, they stamp your passport and create an I-94 record in the CBP system. Your I-94 is your proof of TN status, print it at cbp.gov/i94.
You'll pay the inspection fee. The I-94 shows your admission class (TN) and authorized stay period (typically 3 years from date of entry).
| Denial Reason | Prevention |
|---|---|
| Job title doesn't match USMCA list | Map your actual duties to an approved profession; consult an attorney if ambiguous |
| Insufficient credentials | Verify your degree/license meets the exact credential requirements for the profession |
| Employer letter too vague | Letter must specify all required elements; generic letters are rejected |
| Self-employment or contractor concerns | TN requires employer-employee relationship; independent contractor arrangements are problematic |
| Immigrant intent suspected | TN is technically dual-intent hostile, don't have pending immigrant petitions without preparing an explanation |
| Criminal history or prior violations | Address proactively with an immigration attorney before attempting renewal |
| Factor | Border Renewal | I-129 with USCIS |
|---|---|---|
| Cost | ~$56 | $460 base + optional premium |
| Speed | Same day | 3–5 months regular; 15 days premium |
| Risk | Denial is immediate; no appeals | Can respond to RFEs |
| Travel required | Must physically cross border | Can extend without travel |
| Best for | Straightforward renewals | Complex situations, no-travel-ability |
