INTRODUCTION
This TN visa overview explains how Canadian and Mexican professionals can work legally in the United States under the United States–Mexico–Canada Agreement (USMCA). The TN visa category allows qualified professionals in specific occupations to accept employment with U.S. companies without going through the longer and more expensive visa processes required for many other employment-based visas.
For professionals seeking opportunities in Michigan and throughout the United States, the TN visa offers one of the fastest and most efficient paths to temporary work authorization.
Understanding the eligibility rules, application process, and limitations is essential before pursuing TN status. This TN visa overview provides a clear explanation of how the program works and who qualifies.
TN Visa Overview: Application Process for Canadian and Mexican Citizens
Another important part of any TN visa overview is understanding how the application process differs depending on nationality.
Canadian Citizens
Canadian citizens usually apply for TN status directly at a U.S. port of entry or airport pre-clearance facility.
Applicants must typically present:
• Proof of Canadian citizenship (passport)
• A detailed employer support letter
• Proof of educational qualifications
• Evidence the job qualifies as a TN occupation
If approved, TN status is typically granted for up to three years.
Mexican Citizens
Mexican citizens must first apply for a TN visa at a U.S. consulate before entering the United States. After visa issuance, TN status is granted at the port of entry.

TN Visa Overview: Duration and Extensions
A complete TN visa overview should also explain how long TN status lasts.
TN status may be granted for up to three years at a time. Extensions are possible and can be obtained by:
• Filing an extension with USCIS, or
• Departing the United States and reapplying at the border (for Canadians)
Unlike some other visas, there is no fixed limit on the number of TN renewals, as long as the employment remains temporary.
TN Visa Overview: Important Limitations
Although TN status offers many advantages, there are important limitations.
• TN status is a temporary nonimmigrant visa
• It is employer-specific
• Only listed professional occupations qualify
• It does not directly lead to permanent residence
However, many TN professionals eventually pursue permanent residence through employment-based immigrant visa categories.
When to Consult an Immigration Attorney About a TN Visa
Even though the TN process is relatively streamlined, mistakes in the employer support letter, job classification, or credential documentation can lead to refusal at the border.
An experienced immigration attorney can help ensure that the application clearly demonstrates eligibility under the TN classification.
Professionals considering employment in the United States or U.S. companies seeking to hire Canadian or Mexican professionals should ensure that the documentation meets USMCA requirements.
