Differences in TN Visa Application Process for Canadians vs Mexicans

Key Takeaways

• As of July 17, 2025, TN visa rules align for USCIS and CBP applications, closing previous loopholes.
• Canadian citizens apply for TN status directly at U.S. ports; Mexican citizens require consulate visa approval.
• TN visa is employer-specific; any major job change requires a new application with Form I-129.

The TN visa offers a unique path for Canadian citizens and Mexican citizens to work in the United States 🇺🇸 in certain professional jobs. Recent updates, effective July 17, 2025, have clarified and, in some cases, changed how each group must apply. Understanding these changes is important for anyone planning to use the TN visa, as the rules and steps are different depending on your nationality. Below, you’ll find a clear summary of what has changed, who is affected, what actions are required, and what these updates mean for people with pending applications or those planning to apply soon.

Summary of What Changed

As of July 17, 2025, the United States 🇺🇸 government has updated its guidance on the TN visa process. The main changes include:

• Clearer rules for TN petitions filed with U.S. Citizenship and Immigration Services (USCIS): Now, TN petitions filed through USCIS must meet the same requirements as those reviewed by Customs and Border Protection (CBP) at the border. This closes a loophole that some applicants tried to use in the past.
• No change in the basic process for Canadian citizens and Mexican citizens, but the update makes the requirements more consistent and easier to understand.
• Reminders about employer-specific rules: The TN visa is tied to a specific employer, job title, and job duties. Any major change means you need a new TN application.

Let’s break down what these changes mean for each group, what steps you need to take, and how this affects people with pending or future TN visa applications.

Who Is Affected by These Changes?

• Canadian citizens applying for or renewing a TN visa to work in the United States 🇺🇸.
• Mexican citizens applying for or renewing a TN visa to work in the United States 🇺🇸.
• Employers in the United States 🇺🇸 who want to hire Canadian or Mexican professionals under the TN visa program.
• People with pending TN visa applications or those planning to apply soon.

Background: What Is the TN Visa and Who Can Use It?

The TN visa is a special work visa created under the United States-Mexico-Canada Agreement (USMCA), which replaced the North American Free Trade Agreement (NAFTA). It allows certain professionals from Canada 🇨🇦 and Mexico 🇲🇽 to work in the United States 🇺🇸 for up to three years at a time, with the option to extend.

Eligible jobs include:

• Engineers
• Accountants
• Lawyers
• Scientists
• Teachers
• Many other professional roles listed in the USMCA

Key Points:

• The TN visa is only for Canadian citizens and Mexican citizens.
• You must have a job offer from a U.S. employer in a qualifying profession.
• The job must match your education and experience.

How the TN Visa Application Process Differs for Canadian and Mexican Citizens

For Canadian Citizens

Canadian citizens have a simpler process compared to Mexican citizens. Here’s how it works:

1. Gather Required Documents

Before applying, you need to collect:

• A valid Canadian passport (proof of citizenship)
• Proof of your professional and educational qualifications (like degrees, licenses, or certificates)
• A job offer letter from a U.S. employer describing your job, duties, and how you qualify
• Evidence that you plan to return to Canada 🇨🇦 after your job ends (nonimmigrant intent)
• An employment contract or letter of agreement

2. Apply at a U.S. Port of Entry

Canadian citizens do not need to apply for a visa at a U.S. consulate. Instead, you can go directly to a U.S. port of entry—such as an airport with U.S. preclearance or a land border crossing—and apply for TN status on the spot.

At the port of entry, you will:

• Present your documents to a Customs and Border Protection (CBP) officer
• Answer questions about your job, qualifications, and plans in the United States 🇺🇸
• Pay a processing fee (usually around $50, but check the latest fee on the CBP website)

If approved, you’ll be admitted to the United States 🇺🇸 in TN status and can start working right away.

3. Optional: Pre-Approval by Filing Form I-129

While not required, your U.S. employer can choose to file Form I-129, Petition for a Nonimmigrant Worker with USCIS before you travel. This can be helpful if you want extra assurance before arriving at the border, but it does not guarantee approval by CBP. If USCIS approves the petition, you still need to present the approval notice and your documents at the port of entry.

For Mexican Citizens

Mexican citizens must follow a different, more traditional visa process.

1. Gather Required Documents

You’ll need:

• A valid Mexican passport (proof of citizenship)
• Proof of your professional and educational qualifications
• A job offer letter from a U.S. employer
• An employment contract or letter of agreement

2. Apply at a U.S. Consulate or Embassy in Mexico 🇲🇽

Mexican citizens must apply for a TN visa at a U.S. embassy or consulate in Mexico 🇲🇽. The steps include:

• Complete the DS-160 Online Nonimmigrant Visa Application
• Pay the visa application fee (check the current fee on the U.S. Department of State website)
• Schedule and attend a visa interview at the consulate or embassy
• Bring all your documents to the interview

If approved, you’ll receive a TN visa stamp in your passport.

3. Enter the United States 🇺🇸

Once you have the TN visa in your passport, you can travel to a U.S. port of entry and present your documents to CBP. If everything is in order, you’ll be admitted in TN status and can start working.

Key Differences Between Canadian and Mexican Citizens

• Canadian citizens can apply directly at the border or airport without a prior visa appointment.
• Mexican citizens must first get a TN visa at a U.S. consulate or embassy before traveling to the United States 🇺🇸.
• Both groups must meet the same job and qualification requirements, but the steps and timing are different.

Recent Policy Updates: What’s New as of July 17, 2025?

1. USCIS Policy Manual Updates

USCIS has clarified that TN petitions filed with the agency (using Form I-129) must meet the same requirements as those reviewed by CBP at the border. This means:

• No more “loopholes” for people trying to get around the rules by filing with USCIS instead of applying at the border or consulate.
• All TN applications—whether filed at the border, at a consulate, or with USCIS—must include the same proof of qualifications, job offer, and nonimmigrant intent.

2. Employer-Specific Requirements

The TN visa is employer-specific. This means:

• Your TN status is tied to your employer, job title, and job duties.
• If you change employers, job titles, or job duties in a way that is “material” (a big change), you must file a new TN application.
• If you don’t follow this rule, you could lose your TN status and have to leave the United States 🇺🇸.

3. Extensions and Changes of Status

Both Canadian and Mexican citizens can extend their TN status or change employers, but you must follow the correct steps:

• Extensions: File Form I-129 with USCIS before your current TN status expires.
• Change of Employer: Your new employer must file a new Form I-129 with USCIS.
• Change of Status: If you want to switch to another visa type, you must follow the rules for that visa.

Implications for Pending Applications

If you already have a TN application pending as of July 17, 2025:

• Your application will be reviewed under the updated rules.
• Make sure your application includes all required documents and meets the new standards.

What Actions Should Applicants and Employers Take Now?

For Employers:

6. What if my application is denied?

If your application is denied at the border, you may be able to fix the problem and try again. If denied at the consulate, you may need to provide more information or reapply. Always ask for the reason for denial and address any issues before reapplying.
