How to Secure TN Visa Approval for Eligible Mexican Candidates
A Step-by-Step Guide for U.S. Employers
Hiring top talent from Mexico under the TN visa can be an incredibly efficient and affordable solution for U.S. employers. But success hinges on understanding the legal requirements, proper documentation, and strategic preparation to avoid denials or delays.
In this guide, we’ll walk you through how to maximize your chances of getting a TN visa approved when hiring eligible Mexican professionals—especially engineers, accountants, architects, and IT specialists.
What Is the TN Visa (and Why Is It Employer-Friendly)?
The TN (Trade NAFTA) visa, now operating under the USMCA agreement, allows certain Mexican and Canadian professionals to work in the U.S. in pre-approved occupations without the high costs or complexity of other work visas like H-1B.
- No Labor Certification
- No USCIS filing (for Mexicans)
- Quick turnaround (2–4 weeks)
- Valid for up to 3 years and renewable

Key Requirements for Approval
To get a TN visa approved, three elements must align perfectly: (1) job role, (2) candidate credentials, and (3) employer documentation.
1. The Role Must Match a TN-Eligible Occupation
The job you’re offering must appear exactly on the TN profession list. Example titles include:
- Civil Engineer
- Architect
- Industrial Designer
- Accountant
- Systems Analyst
- Registered Nurse
Avoid using vague or non-listed job titles like “project manager” or “developer”—these could lead to rejection unless carefully rephrased.
2. The Candidate Must Have the Right Degree or License
TN applicants must present proof of academic qualifications directly related to the job. Typically this means:
- A bachelor’s degree (or higher) in the relevant field
- Transcripts and/or diplomas translated into English
- In regulated fields (like nursing or architecture), state-specific licenses or certifications may also be required

3. The Employer Must Provide a Clear, Compliant Job Offer
The job offer letter is the centerpiece of a successful TN visa application. It must be:
- Written on company letterhead
- Include the candidate’s full name and nationality
- Describe the job title and duties in detail (matching a TN category)
- Include duration of employment (up to 3 years)
- Specify salary and work location
- Signed by a senior company official
Sample templates can be found via many immigration law firms, or consult the American Immigration Lawyers Association (AILA) for professional drafting support.

How to Prepare for the Consulate Interview (Mexico)
Most TN applicants from Mexico must attend an in-person interview at a U.S. Consulate. Here’s how to succeed:
During the Interview, the Applicant Should:
- Confidently explain the job duties
- Emphasize that it’s a temporary role (non-immigrant intent)
- Show understanding of the company and project
- Avoid bringing up “immigration plans” or future green cards

Common Reasons for TN Visa Denial (and How to Avoid Them)
| Reason | How to Avoid It |
|---|---|
| Job title doesn’t match TN list | Use exact TN-recognized titles |
| Lack of supporting documents | Double-check degree, offer letter, and ID |
| Weak employer letter | Make it specific, signed, and detailed |
| Inconsistent job duties | Align them with the TN job description |
| Lack of ties to Mexico | Emphasize temporary stay, return plans |
If your application is denied, it may be possible to reapply quickly with corrected documents or updated employer support.
