The TN visa is available to eligible Canadian and Mexican citizens in professions listed under the USMCA agreement. Applicants need proof of citizenship, a job offer, and qualifications matching the listed profession. The maximum stay is up to three years, with unlimited renewals. Costs are about $50 at the border plus a $6 I-94 fee (consular fees may vary). The process is low to moderately difficult if the role matches the TN list, and visa agency involvement is required. Processing is usually same-day at the border/port of entry or takes weeks for consular processing. The approval rate is approximately 95%.
