TN Visa Requirements: Eligibility, Education, and What CBP Actually Checks

You got a U.S. job offer. Your start date is in three weeks. Now you need to figure out if you qualify for a TN visa — and what CBP will actually scrutinize when you show up at the border.

The TN (Trade NAFTA, now governed by USMCA) is deceptively simple on paper: be Canadian or Mexican, work in one of 63 designated professions, have a U.S. job offer. But the gap between "technically eligible" and "approved at the border" is where most problems happen.

Here are the four requirements that matter.

1. Nationality

TN status is exclusively available to citizens of Canada or Mexico. Permanent residents of either country do not qualify — citizenship is required. You'll need a valid passport to prove it.

This is binary — either you qualify or you don't. No exceptions, no waivers.

2. Your Profession Must Be on the USMCA List

The USMCA designates exactly 63 professional categories. If your occupation isn't on the list, you cannot get a TN — full stop. The list includes roles like Engineer, Computer Systems Analyst, Accountant, Management Consultant, Registered Nurse, Pharmacist, and 57 others.

The tricky part: the list was written in 1994 and hasn't been updated since. Modern job titles rarely map cleanly to 1994-era definitions. A "Data Engineer" applying as an "Engineer" may face questions. A "Software Developer" applying as a "Computer Systems Analyst" will need to carefully document that their duties focus on analysis and system design — not pure coding.

Each profession also has minimum education requirements. Most require a Baccalaureate or Licenciatura degree. Some allow a Post-Secondary Diploma plus years of experience. Management Consultant allows five years of relevant experience with no degree at all. See the full TN visa professions list for category-by-category breakdowns.

3. A Qualifying Job Offer from a U.S. Employer

You must have an actual job offer from a U.S. entity. The offer must be for work that falls within your designated TN profession. The employer will provide a support letter — this is the single most important document in your application.

The letter must do more than confirm employment. It needs to describe your duties in language that aligns with the USMCA profession definition, state the salary and duration (maximum three years per application), and include language confirming the temporary nature of the assignment.

There's no sponsorship petition required for Canadians — the employer's letter is the petition. Mexicans require consular processing with additional documentation.

4. Nonimmigrant Intent

This is the requirement that catches long-term TN holders off guard. Unlike H-1B status, TN status does not permit "dual intent." Every time you apply or renew, you must demonstrate that your stay is temporary and that you intend to depart at the end of your authorized period.

In practice, this means: don't have a pending I-140 or I-485 on file when you show up at the border. Officers can see pending immigrant petitions in the CBP system. An active green card application is strong evidence of immigrant intent — and can result in denial even if all your other paperwork is perfect.

What CBP Actually Reviews

For Canadians applying at the land border, a CBP officer will look at:

• Your Canadian passport (citizenship proof)
• The employer's support letter
• Your educational credentials (original diplomas and transcripts)
• Credential evaluation if your degree is from outside the U.S., Canada, or Mexico
• The $50 I-94 fee

The interview typically takes 30 to 90 minutes in secondary inspection. Officers are specifically trained to verify that your described duties match the DOL Occupational Outlook Handbook definition of the claimed profession — not your LinkedIn title, not your company's internal job description.

For Mexicans, requirements include all of the above plus a DS-160 application, $185 MRV visa fee, biometric appointment, and an in-person consular interview.

Common Reasons Applications Fail

Degree mismatch. A Computer Science degree being used to apply as an "Engineer" has faced increasing rejection since 2025 policy updates. Officers may now require that the degree field match the profession — "Computer Science Engineer" or "Software Engineering" degrees are safer than generic "Computer Science."

Vague duty descriptions. "Will perform various IT tasks" guarantees scrutiny. Duties must map precisely to the regulatory definition, not a paraphrased version.

Managerial framing. The TN is for professionals, not managers. A letter that emphasizes team leadership and budget oversight over technical professional work raises red flags. Your primary function must be professional — management can be incidental, not primary.

Evidence of immigrant intent. Ongoing green card proceedings, unexpired I-140 approvals, or I-485 pending status can trigger denial based on immigrant intent.
