TN Visa Employer Requirements: What U.S. Employers Need to Know Before Hiring Canadian or Mexican Professionals

  • June 26, 2025

If your company is looking to hire skilled professionals from Canada or Mexico, the TN Visa offers a fast-track option under the United States-Mexico-Canada Agreement (USMCA). While the process is often more straightforward than other work visas, U.S. employers still have important responsibilities and legal requirements to fulfill.

Here’s what you need to know as a prospective TN Visa employer.

1. Offer a Position That Qualifies Under USMCA

The TN Visa only applies to certain occupations listed in the USMCA (formerly NAFTA) Appendix 1603.D.1, such as:

  • Engineers
  • Accountants
  • Computer Systems Analysts
  • Scientists
  • Medical professionals
  • Architects
  • Teachers (post-secondary)

The job title, duties, and qualifications must align with the official list. If your role doesn’t match a listed category, it may not qualify—even if the employee is highly skilled.

Tip: The job description should clearly connect to one of the approved TN professions. Vague or hybrid roles can raise red flags.

2. Provide a Detailed Offer Letter

Employers must issue a formal employment offer letter on company letterhead, signed by an authorized representative. This letter is the centerpiece of the TN Visa application.

It should include:

  • The job title and detailed duties
  • The TN occupational category it falls under
  • Duration of the employment (up to 3 years, renewable)
  • Salary and work location
  • A statement that the position is temporary (even if renewable)

Important: TN status does not lead directly to a green card. The job must be non-permanent in nature—even if the employee stays for multiple terms.

3. Confirm the Employee’s Qualifications

The employee must hold the necessary degree, license, or professional credentials required for the TN category. Employers are expected to verify this before extending the offer.

  • For example, a “TN Economist” must hold a degree in economics or a related field.
  • A nurse must hold the proper licensing for the role.

4. Understand the Application Process (By Country

For Canadian citizens:
They can apply directly at a U.S. Port of Entry with the offer letter, credentials, and supporting documents. There’s no petition required in advance from the employer.

For Mexican citizens:
They must first apply for a TN Visa at a U.S. consulate in Mexico. Once approved, they can enter the U.S. and begin work.

Employers do not sponsor the visa in the traditional sense, but they are still critical to the process—especially in preparing the offer letter and validating the role.

5. Maintain Compliance

Once the TN professional is hired, the employer should:

  • Ensure the employee works only in the role and location described
  • Notify legal counsel if job duties or locations change
  • Keep accurate records of employment
  • Be aware of renewal timelines (typically every 3 years)

Employers should not treat TN hires as independent contractors unless explicitly allowed. Misclassification can lead to visa denials or compliance issues in the future.

6. Work With an Immigration Attorney

While the TN Visa is one of the more efficient work authorization options, it still requires strategic planning. Employers who assume it’s “just paperwork” risk delays or denials.

Attorney Maria Fitzmaurice works closely with both employers and employees to:

  • Assess whether a position qualifies under TN rules
  • Prepare offer letters that meet U.S. immigration standards
  • Guide Mexican applicants through the consular process
  • Support HR and compliance teams throughout the employee’s stay
