TN Visa Requirements 2026: 63 Professions, Fees & 3-Year Limit

Quick answer: TN Visa Requirements 2026: 63 Professions, Fees & 3-Year Limit let Canadian and Mexican citizens work in the U.S. across 63 USMCA professions. Canadians apply at the border with no visa fee; Mexicans pay a $185 MRV fee and attend a consular interview. Initial stays are granted up to three years and can be renewed indefinitely in three-year increments, but TN is single-intent — pursuing a green card while in TN risks denial of re-entry.

TN Visa Requirements 2026: 63 Professions, Fees & 3-Year Limit

The TN classification was created under NAFTA in 1994 and is now governed by the United States–Mexico–Canada Agreement (USMCA), effective July 1, 2020. Only citizens of Canada and Mexico are eligible — lawful permanent residents of either country do not qualify. The USMCA Appendix 2 (Annex 16-A) enumerates exactly 63 professions across five broad categories: General, Medical/Allied, Scientists, Teachers, and Management Consultants.

There is no annual numerical cap on TN admissions, unlike the H-1B lottery. However, TN is a single-intent classification under 8 CFR 214.6: you must maintain a temporary intent. Filing an immigrant petition (I-140) or adjusting status while in TN can trigger denial of readmission at the border. I've seen clients forced to switch to H-1B or L-1 before starting the green-card process — plan this with an immigration attorney before your first TN entry.

Last verified: October 2026. Fees, processing times, and adjudication standards change; always confirm with USCIS, CBP, or the U.S. Department of State before acting.

The 63 USMCA Professions at a Glance

Below is a condensed breakdown of the five categories and representative roles. For the full list with minimum education and licensing requirements, see the USCIS TN professions page.

What Are the TN Visa Requirements for Canadian Citizens?

Canadians are visa-exempt for TN. You do not need a consular visa stamp. Instead, you present your case directly to a CBP officer at a U.S. port of entry (land border, airport, or pre-clearance facility in Canada). Bring:

• Valid Canadian passport
• Employer support letter (see details below)
• Original or certified copies of degrees, licenses, and experience letters matching the profession's requirements
• Proof of Canadian citizenship (passport suffices)

The CBP officer adjudicates on the spot — typically under one hour. If approved, you receive a Form I-94 admission record valid for up to three years. The I-94 is now electronic; retrieve it at i94.cbp.dhs.gov after entry.

Real-world tip: Pre-clearance airports (Toronto Pearson, Vancouver, Montreal, Calgary, Edmonton, Winnipeg, Halifax, Ottawa) often have shorter waits than land borders. I've had clients cleared in 20 minutes at Toronto Terminal 1. Avoid Friday afternoons and holiday weekends.

Step-by-Step: Canadian TN Application at the Border

1. Gather all documents listed above. Organize them in a folder: passport, employer letter, degrees, licenses, experience letters.
2. Choose a port of entry. Pre-clearance airports are fastest; land borders can have long lines.
3. Inform the CBP officer you are seeking TN admission. Hand over your packet.
4. Answer questions about your role, employer, and qualifications. Be concise and truthful.
5. If approved, the officer will stamp your passport and create an electronic I-94. Verify the I-94 online within 24 hours for accuracy.

If the officer has concerns, they may refer you to secondary inspection. Stay calm, provide any additional documents requested, and do not volunteer information about immigrant intent.

What Are the TN Visa Requirements for Mexican Citizens?

Mexican citizens must obtain a TN visa stamp at a U.S. consulate in Mexico before travel. The process:

1. Complete Form DS-160 online and print the confirmation page.
2. Pay the MRV fee of $185 (2026 rate) plus any applicable reciprocity fee (currently $0 for Mexico).
3. Schedule a visa interview at a U.S. consulate in Mexico (Mexico City, Ciudad Juárez, Guadalajara, Hermosillo, Matamoros, Mérida, Monterrey, Nogales, Nuevo Laredo, Tijuana).
4. Attend the interview with: passport, DS-160 confirmation, MRV receipt, employer support letter, and profession-specific credentials (degrees, licenses, experience letters).

The consular officer verifies your qualifications and temporary intent. If approved, the visa stamp is placed in your passport. At the U.S. port of entry, CBP issues the Form I-94 for up to three years.

Processing reality: As of October 2026, wait times for interview appointments range from 2 to 8 weeks depending on the consulate. Monterrey and Mexico City are busiest. Book the appointment before your employer finalizes the start date.

Step-by-Step: Mexican TN Visa Application at Consulate

1. Complete DS-160 accurately. Save the confirmation page with barcode.
2. Pay the $185 MRV fee via the designated bank or online portal. Keep the receipt.
3. Schedule the interview through the U.S. Visa Appointment System. Choose the consulate nearest your residence.
4. Prepare a document package: passport, DS-160 confirmation, MRV receipt, employer letter, degrees, licenses, experience letters, and any required translations.
5. Attend the interview. The officer will focus on your qualifications and the temporary nature of the job.
6. If approved, the visa is usually ready for pickup within 3-5 business days.

Employer Support Letter: What Must It Include?

Whether you're Canadian or Mexican, the employer letter is the single most important document. A weak letter is the #1 reason for TN denials. It must be on company letterhead, signed by an authorized hiring official, and contain:

• Detailed job description matching a USMCA profession
• Required qualifications (degree, license, years of experience)
• Salary or wage meeting prevailing wage for the occupation and location
• Employment start date and anticipated end date (or "indefinite" with three-year increments)
• Statement that the position is temporary and the employee will depart upon completion
• Contact information for the employer's immigration liaison

I recommend attaching an organizational chart showing where the TN role fits — it helps the officer see the professional nature of the job.

Document Checklist for TN Applicants

Renewing TN Status: Extensions vs. Re-entry

You have two main paths to stay beyond the initial three years:

• Mail-in extension (Form I-129): Employer files with USCIS before the I-94 expires. Premium processing (15 calendar days) is available for $2,805 (2026 fee). You stay in the U.S. while it's pending.
• Re-entry at the border: Canadians simply re-present the packet; Mexicans need a valid visa stamp (or apply for a new one if expired). This resets the three-year clock.

Both methods are valid indefinitely if you maintain temporary intent. However, repeated mail-in extensions can attract scrutiny — officers may question whether the role is truly temporary. Many practitioners alternate: one extension by mail, next by re-entry.

Maintaining Temporary Intent: Practical Tips

The single-intent rule is the biggest risk for long-term TN holders. To avoid problems:

• Never carry immigrant petition receipts (I-140, I-485) when entering on TN.
• Keep a clear paper trail showing the job is project-based or has a defined end date, even if renewed.
• If your employer starts a green-card process, switch to H-1B or L-1 before the PERM filing.
• Consult an immigration attorney before any change in employment or family circumstances that could imply permanent intent.

Dependents: TD Status for Spouses and Children

Spouses and unmarried children under 21 qualify for TD (Trade Dependent) status. They cannot work in the U.S. but may attend school. Canadians apply for TD at the same port of entry; Mexicans need a TD visa stamp (same DS-160, $185 fee). TD status is valid only while the principal TN holder maintains status.

Common Pitfalls That Trigger Denials

• Job title mismatch: "Software Engineer" is not a listed profession; "Computer Systems Analyst" is. Map duties to the exact USMCA title.

  Frequently asked questions

  Can I apply for a TN visa if I am a permanent resident of Canada or Mexico but not a citizen?

  No. Only citizens of Canada or Mexico qualify for TN status. Lawful permanent residents must use other visa categories such as H-1B or L-1.

  Is there a limit on how many times I can renew my TN status?

  There is no statutory limit. You can renew indefinitely in three-year increments as long as you maintain temporary intent and continue to meet the profession requirements.

  What is the current fee for a Mexican citizen to apply for a TN visa?

  As of October 2026, the MRV fee is $185. There is no additional reciprocity fee for Mexico.

  Can my spouse work in the U.S. while on TD status?

  No. TD dependents are not authorized to work. They would need their own work visa (e.g., TN, H-1B) to be employed.

  Do I need a labor condition application (LCA) for a TN visa?

  No. Unlike H-1B, TN does not require an LCA or prevailing wage determination, though the employer must still pay a wage that meets the prevailing wage for the occupation and location.
