What Is a TN Visa? USMCA Professional Visa Explained

The Short Answer

The TN visa is a nonimmigrant work classification for Canadian and Mexican citizens working in the United States in specific professional occupations. It was created by the North American Free Trade Agreement (NAFTA) in 1994 and continued under the United States-Mexico-Canada Agreement (USMCA) that replaced NAFTA in 2020. TN status allows qualifying professionals to work for a U.S. employer without going through the H-1B lottery, without an annual numerical cap, and typically with much simpler processing than most other work visas.

For Canadian citizens, a TN is remarkably fast and simple — it can be granted at the U.S. port of entry on presentation of the right documents. For Mexican citizens, TN requires applying for a TN visa at a U.S. consulate first and then entering with the visa. The underlying eligibility rules are the same for both, but the procedural path is different.

Who Qualifies

To qualify for a TN, an applicant must meet five main criteria:

1. Citizenship. The applicant must be a citizen of Canada or Mexico. Permanent residents of those countries who are not citizens do not qualify.
2. Profession on the list. The applicant's occupation must appear on the list of TN professions in USMCA Appendix 2 (formerly NAFTA Chapter 16 Appendix 1603.D.1). The list includes scientists, engineers, accountants, management consultants, lawyers, pharmacists, physicians (for teaching and research only), architects, scientific technicians, and many others. If the occupation is not on the list, TN is not an option.
3. Qualifications. The applicant must have the minimum educational or licensure requirements for the specific profession, as listed in USMCA Appendix 2. Most categories require a bachelor's degree or higher in the specific field. A few categories accept alternative credentials.
4. Prearranged U.S. employment. The applicant must have a specific offer of employment from a U.S. employer. Self-employment in the U.S. under TN is not permitted.
5. Temporary intent. The applicant must intend the stay to be temporary. TN is a nonimmigrant classification and does not allow dual intent in the same way H-1B does.

Canadian TN: Fastest Path in U.S. Immigration

For Canadian citizens, the TN process is remarkably direct. A Canadian can apply for TN admission at the U.S. port of entry — typically at a land border crossing, a preflight inspection airport in Canada, or sometimes at arriving flights with CBP on duty.

The applicant presents:

• Proof of Canadian citizenship (passport).
• Offer letter from the U.S. employer specifying the profession, duties, duration of employment, and salary.
• Proof of credentials — typically the university degree and transcripts, and any required professional licenses.
• Evidence that the position fits one of the TN professions on the list.

The CBP officer reviews the package and, if satisfied, admits the applicant under TN status and stamps the passport or annotates the I-94 record with TN and an expiration date. The processing time at the border is usually minutes to hours. No consular visa is required.

Mexican TN: Consular Processing Required

Mexican citizens follow a two-step process: they first apply for a TN visa at a U.S. consulate in Mexico, and then they enter the U.S. with the visa for admission in TN status.

The consular application uses Form DS-160 and requires an interview at a U.S. consulate. Processing times depend on interview availability at the specific consular post. Once the visa is issued, the holder can enter the U.S. in TN status through any port of entry.

How Long Does TN Last?

TN status can be granted for up to three years at a time. There is no limit on the number of extensions — a TN professional can theoretically renew TN status indefinitely, as long as they continue to meet the eligibility requirements and maintain temporary intent. In this sense, TN is unusual among U.S. work visas because there is no equivalent of the H-1B six-year cap.

However, the temporary intent requirement creates practical complications. If a TN professional eventually wants to apply for a U.S. green card, they may face scrutiny at TN renewals because an approved I-140 or filed I-485 can be treated as evidence of immigrant intent, which is inconsistent with TN classification. Many practitioners advise TN professionals to be careful with the timing of permanent residence applications.

What Professions Are on the TN List?

The USMCA Appendix 2 list includes dozens of specific occupations. Some of the most common:

• Accountant
• Architect
• Computer Systems Analyst
• Engineer (various fields)
• Graphic Designer
• Hotel Manager
• Industrial Designer
• Interior Designer
• Land Surveyor
• Landscape Architect
• Lawyer
• Librarian
• Management Consultant
• Mathematician (including Statistician and Actuary)
• Medical Technologist
• Nutritionist
• Occupational Therapist
• Pharmacist
• Physicist
• Psychologist
• Registered Nurse
• Research Assistant
• Scientific Technician/Technologist
• Social Worker
• Teacher (college, seminary, or university)
• Veterinarian

Each profession has specific educational or licensure requirements. A few professions (like registered nurse and physical therapist) require U.S. state licensure in addition to the foundational credentials. Review the USMCA list carefully to confirm that your offered position falls within one of the enumerated categories.

What the Application Offer Letter Must Include

The U.S. employer's offer letter is the central document in any TN application. It should include:

• The specific TN profession title (matching the USMCA list exactly if possible).
• A detailed description of the duties that show the work is professional in nature and fits the TN category.
• The anticipated duration of the employment (up to three years).
• The salary or compensation.
• The minimum qualifications for the position, matching what the applicant can document.
• The employer's U.S. address and contact information.

A weak, vague, or mismatched offer letter is the most common reason TN applications are denied or delayed.

The Bottom Line

The TN visa is a USMCA nonimmigrant work classification available to Canadian and Mexican citizens in specific professional occupations. For Canadians, processing at the port of entry can take minutes. For Mexicans, a consular visa is required first. TN has no numerical cap, no lottery, and allows three-year periods of admission with unlimited renewals — but it requires temporary intent, so it does not mix easily with a U.S. green card pursuit. For your specific situation, consult a licensed U.S. immigration attorney who handles TN cases regularly.

When to Work with an Immigration Attorney

Not every immigration question needs a lawyer, but some do. The topics covered in this article include situations where a brief consultation with a licensed U.S. immigration attorney can save months of delay, prevent irreversible mistakes, and identify options you might not otherwise know about. Consider consulting an attorney if your case involves any of the following:

• Criminal history of any kind. Even dismissed charges, expunged records, or decades-old offenses can affect immigration outcomes. The immigration consequences of a criminal record are technical and fact-specific, and plea deals that seemed favorable in criminal court sometimes have devastating immigration consequences.
• Past immigration violations or denials. Prior visa denials, overstays, periods of unlawful presence, and prior removal proceedings all affect current options. An attorney can review your history and identify which paths remain open.
• Complicated family situations. Divorce, death of a petitioner, domestic abuse, and similar circumstances can trigger waiver eligibility or affect existing petitions in ways that require careful legal analysis.
• Business immigration matters. Employment-based cases, investor visas, and self-petitions are typically too complex for do-it-yourself filing. The evidentiary standards are demanding and the stakes are high.
• Cases that feel stuck. If your case has been sitting without action for a long time, or if you received an RFE or NOID you do not fully understand, an attorney can diagnose the problem and respond effectively.
• Anything you do not fully understand. Immigration forms are technical, and a small mistake can cascade into large consequences. When in doubt, ask someone qualified.

Finding Reliable Information

The single most reliable source of current U.S. immigration information is USCIS itself. USCIS publishes form instructions, fee schedules, processing times, policy manuals, and policy alerts at uscis.gov. When any article (including this one) references specific fees, processing times, or eligibility rules, the information can become outdated as USCIS updates its policies and fee schedules. Always verify any time-sensitive detail directly with USCIS before filing anything.

Other reliable primary sources include the U.S. Department of State (for visa bulletins and consular processing), the U.S. Department of Labor (for PERM and prevailing wage information), U.S. Customs and Border Protection (for admission and port of entry rules), and the Executive Office for Immigration Review (for immigration court procedures).

Secondary sources — including practitioner guides, law school immigration clinics, and reputable nonprofit legal aid organizations — can provide helpful explanations of how the rules apply in practice. Community forums and social media should be treated with caution: they can point you to useful resources, but they also contain a great deal of inaccurate or outdated information, and the rules change frequently enough that what was true a year ago may not be true now.

Keeping Records

One of the simplest ways to protect yourself through any immigration process is to keep careful records of everything. Copies of every filing you send to USCIS, every notice you receive, every check or money order you submit, and every piece of correspondence you send or receive become critical evidence if something goes wrong later. Keep these records organized, dated, and backed up in at least two separate places (for example, a physical folder and a digital scan).

Also keep records of everything that supports your underlying eligibility — tax returns, marriage certificate, birth certificates, medical records, employment records, property records, school transcripts, and anything else that demonstrates ties to the United States, family relationships, or program eligibility. Good records are the backbone of a strong immigration case.
