Chula Vista's proximity to the Mexican border makes TN visa applications especially convenient for Mexican professionals seeking U.S. employment. SoCal Immigration Services helps qualified professionals navigate TN requirements and border application procedures.

Understanding the TN Visa

The TN (Trade NAFTA) visa is a special work authorization created under the North American Free Trade Agreement, now continued under the United States-Mexico-Canada Agreement (USMCA).

Key Features:

TN status allows professionals in designated categories to work for U.S. employers in their professional capacity. The visa is employer-specific—you can only work for the sponsoring employer. Unlike H-1B, there's no annual cap limiting the number of TN visas issued.

Duration and Renewal:

TN status is granted for up to three years initially. It can be renewed indefinitely in three-year increments as long as you maintain qualifying employment. There's no maximum cumulative duration, though extended stays may raise immigrant intent concerns.

TN Professional Categories

Only professionals in occupations listed in USMCA's professional categories qualify for TN status. Each category has specific requirements.
  • Accountants: Baccalaureate degree or professional certification (CPA, CMA, etc.)
  • Engineers: Baccalaureate degree in relevant engineering field
  • Computer Systems Analysts: Baccalaureate degree or post-secondary diploma with three years' experience
  • Scientists: Baccalaureate degree in relevant scientific field (biologists, chemists, physicists, etc.)
  • Management Consultants: Baccalaureate degree or five years' experience in consulting
  • Teachers: Baccalaureate degree (for college, university, or seminary only)
  • Medical Professionals: Various requirements depending on specific profession
  • Other Professionals: Architects, lawyers, pharmacists, and other designated categories

Requirements for Mexican TN Applicants

Mexican professionals must meet several requirements to qualify for TN status.
  • Mexican Citizenship: Must be a citizen of Mexico (permanent residents don't qualify)
  • Qualifying Profession: Job must fall within a designated USMCA professional category
  • Credentials: Must have the educational qualifications or experience required for the profession
  • Job Offer: Must have a job offer from a U.S. employer for work in the professional capacity
  • Temporary Intent: Must intend to depart when TN status ends (non-immigrant intent)
  • No Labor Condition Application: Unlike H-1B, TN doesn't require LCA filing

Border Application Process

Mexican TN applicants can apply at U.S. ports of entry, making the process faster than consular applications.
  1. 1
    Obtain Job Offer Letter

    Secure a detailed offer letter from your U.S. employer stating: professional activity, purpose of employment, anticipated length of stay, your qualifications, and arrangements for remuneration.

  2. 2
    Gather Credential Documentation

    Collect proof of your professional qualifications: university degrees, transcripts, professional licenses, or experience letters. Include certified translations if documents aren't in English.

  3. 3
    Prepare Supporting Documents

    Assemble: valid Mexican passport, job offer letter, credential documents, resume/CV, and any additional evidence supporting your professional qualifications.

  4. 4
    Present at Port of Entry

    Arrive at a U.S. port of entry (San Ysidro, Otay Mesa, etc.). Request TN classification and present your documentation to the CBP officer for adjudication.

  5. 5
    Pay Required Fee

    Pay the I-94 fee (currently $6) if approved. The officer will issue your I-94 showing TN status and authorized stay period.

  6. 6
    Begin Employment

    You can begin working for the sponsoring employer immediately upon TN approval. Your I-94 serves as your work authorization.

Credential Evaluation

Proper documentation of your qualifications is critical for TN approval.

Degree Requirements:

Most TN categories require a baccalaureate (bachelor's) degree in a relevant field. Mexican degrees from accredited institutions are accepted. Bring your original degree and official transcripts.

Credential Evaluation:

While not always required, a credential evaluation from a recognized service (like WES or ECE) can help if your degree was from a less familiar institution or if the field of study isn't obviously related to your profession.

Professional Licenses:

For professions requiring licensure (like engineering or accounting in some states), understand whether U.S. licensure is needed and how your Mexican credentials transfer.

Employer Letter Requirements

The employer support letter is crucial for TN approval. It must contain specific information.
  • Professional Activity: Clear description of the professional work you'll perform
  • Position Details: Job title, duties, and how they relate to the TN profession
  • Qualifications: Statement of your qualifications for the position
  • Employment Period: Anticipated dates of employment (up to three years)
  • Compensation: Salary or hourly rate and payment arrangements
  • Company Information: Employer's name, address, and nature of business
  • Supervisor Information: Contact information for someone who can verify the offer

Common TN Denial Reasons

Understanding denial reasons helps you prepare a stronger application.
  • Not a Qualifying Profession: The job doesn't match any USMCA professional category
  • Insufficient Credentials: Education or experience doesn't meet category requirements
  • Job Duties Mismatch: The actual work isn't professional-level despite the job title
  • Weak Employer Letter: Missing required information or vague descriptions
  • Immigrant Intent: Evidence suggesting plans to remain permanently
  • Previous Immigration Issues: Overstays, misrepresentation, or other violations

TN Status and Immigrant Intent

One significant limitation of TN status is the non-immigrant intent requirement.

The Dual Intent Problem:

Unlike H-1B, TN doesn't allow 'dual intent.' You must intend to depart when your TN employment ends. Having a pending green card application can create problems at TN renewal.

Practical Considerations:

Many TN holders do eventually pursue green cards, but timing matters. Renewing TN indefinitely while maintaining immigrant intent claims can become difficult. Some professionals use TN temporarily while employer sponsors their green card through H-1B conversion.

Planning Your Path:

If permanent residence is your long-term goal, discuss strategy with immigration professionals early. The TN-to-green card path requires careful planning.

Renewing TN Status

TN status can be renewed indefinitely as long as you maintain qualifying employment.

Renewal Options:

You can renew at a port of entry (convenient for Chula Vista residents) or your employer can file Form I-129 with USCIS. Port of entry renewal is typically faster.

Renewal Timing:

Apply for renewal before your current status expires. You can renew up to 10 days before expiration at the border. Don't let status lapse—that creates complications.

Changed Employers:

If changing employers, you need new TN authorization from the new employer. The previous TN doesn't transfer. You can apply at the border with documentation from the new employer.

FAQFrequently Asked Questions

Q:Can I apply for TN visa at the border?

A: Yes. Mexican citizens can apply for TN status directly at U.S. ports of entry like San Ysidro or Otay Mesa. Bring your passport, employer letter, and credential documentation. No visa appointment is needed.

Q:Is there a cap on TN visas like H-1B?

A: No. Unlike H-1B, there's no annual cap limiting TN visas. Qualified professionals can apply year-round without worrying about lottery systems or annual limits.

Q:How long can I stay on TN status?

A: TN is granted for up to three years initially and can be renewed indefinitely in three-year increments. There's no maximum cumulative duration, but extended stays may raise immigrant intent concerns.

Q:Can I apply for a green card while on TN?

A: TN requires non-immigrant intent, which can conflict with green card applications. Careful planning is needed if permanent residence is your goal. Many professionals transition to H-1B (which allows dual intent) before pursuing green cards.

Q:What if my job isn't on the TN professions list?

A: Only jobs matching designated USMCA professional categories qualify. If your occupation isn't listed, you'll need a different visa category (H-1B, O-1, etc.). The professions list is fixed by treaty.

Q:Can my family come with me on TN?

A: Yes. Your spouse and unmarried children under 21 can receive TD (Trade Dependent) status. TD dependents can study but cannot work without their own work authorization.
