What Is the TN Visa?
The TN visa is a nonimmigrant work visa exclusively for citizens of Canada and Mexico under the United States-Mexico-Canada Agreement (USMCA, formerly NAFTA). It allows professionals in designated occupations to work in the United States without going through the H-1B lottery, without an annual cap, and with a streamlined application process that can result in same-day approval at the border for Canadian citizens.
TN Visa Requirements
To qualify for a TN visa you must be a citizen of Canada or Mexico (not just a resident), have a job offer from a U.S. employer in one of the designated TN professions, possess the qualifications required for that profession (typically a bachelor's degree or equivalent), and the work must be temporary (though the visa is renewable indefinitely). The position must be a prearranged, full-time or part-time professional role — self-employment does not qualify.
TN Profession List
The USMCA lists over 60 qualifying professions organized by category. Common TN professions include accountants, architects, computer systems analysts, economists, engineers (all disciplines), graphic designers, management consultants, pharmacists, physicians (for teaching or research only), psychologists, registered nurses (RNs), scientific technicians, teachers, and technical writers. Each profession has specific degree or credential requirements detailed in the USMCA appendix.
Application Process: Canadian Citizens
Canadian citizens have the simplest TN application process in U.S. immigration. No visa stamp is needed — Canadians apply directly at the U.S. port of entry (border crossing or airport preclearance). Present your Canadian passport, the TN application letter from your U.S. employer, proof of your qualifications (degree, transcripts, professional licenses), and the $56 CBP processing fee. If approved, you receive a TN I-94 stamp on the spot. Many Canadians receive approval within 30 minutes.
Application Process: Mexican Citizens
Mexican citizens must apply for a TN visa at a U.S. consulate before traveling. Schedule a visa interview, present Form DS-160, the employer support letter, proof of qualifications, and pay the $185 visa fee. Processing takes 1-3 weeks. After receiving the visa stamp, enter the U.S. at any port of entry.
Duration and Renewals
TN status is granted for up to 3 years per admission. It can be renewed indefinitely in 3-year increments — there is no maximum total stay. Renewals can be done at the border (Canadians), at the consulate (Mexicans), or through a change of status filing (Form I-129) with USCIS from inside the U.S. While TN is technically "temporary," the indefinite renewability makes it functionally long-term for many professionals.
TN Visa to Green Card
The biggest challenge with the TN visa is its nonimmigrant intent requirement — unlike dual intent visas like H-1B. This nonimmigrant intent requirement — you must demonstrate that your stay is temporary. This creates tension if you are also pursuing a green card. However, with careful planning, the TN to green card pathway is achievable. The key is timing: avoid filing for permanent residence while your TN application is pending, and consider transitioning to H-1B (which allows dual intent) before beginning the green card process.
TN vs H-1B: Key Differences
TN advantages: no lottery, no annual cap, lower cost, faster processing, and indefinite renewals. H-1B advantages: allows dual intent (you can pursue a green card simultaneously), covers more occupations, and is not limited to Canadian and Mexican citizens. For Canadian and Mexican professionals in TN-eligible occupations, TN is almost always the better initial option due to its speed and simplicity. See our H-1B guide for comparison.
Common TN Visa Issues
Frequent problems include the position not matching a TN profession exactly (job titles must align closely with the USMCA list), management consultant applications facing heightened scrutiny (USCIS and CBP frequently challenge this category), degree requirements not met (some professions accept experience in lieu of a degree, others do not), and self-employment attempts (TN does not allow self-employment — you must work for a U.S. employer).
Pro tip for Canadians: Apply at a land border crossing during off-peak hours for the fastest processing. Carry extra copies of all documents. If denied at one port, you can try another — each CBP officer makes an independent determination. See our Mexican professionals TN guide for Mexico-specific strategies.
