TN Visa Country Eligibility List — NAFTA Requirements

The TN Country Eligibility List Is Two Countries Long

The TN nonimmigrant classification exists because of a trade agreement, not because of general immigration policy. The United States-Mexico-Canada Agreement (USMCA), which replaced the North American Free Trade Agreement (NAFTA) in 2020, permits citizens of Canada and Mexico to work temporarily in the United States in designated professional occupations. That is the entire eligibility list: Canadian citizens and Mexican citizens. No other nationality qualifies for TN status, regardless of where they live, where they were educated, or what occupation they practice.

The TN category is treaty-specific. Unlike H-1B status, which is available to any foreign national with a qualifying employer and degree, TN status is restricted to nationals of the two countries that signed the agreement with the United States. A Brazilian engineer living in Toronto cannot apply for TN status. A French accountant with a job offer in San Diego cannot use the TN route. Citizenship in Canada or Mexico is the threshold requirement — residency, education, and work history in North America do not substitute for it.

This article explains why the TN country list is limited to two countries, what that limitation means for applicants, and what options exist for professionals who do not qualify by nationality.

Why the TN List Contains Only Canada and Mexico

TN status was created as part of NAFTA's cross-border labor provisions. The goal was to facilitate trade by allowing Canadian and Mexican professionals to work temporarily in the United States without the visa lottery, annual caps, or lengthy petition timelines that apply to other work categories. USMCA preserved this structure when it replaced NAFTA in 2020, maintaining the list of professions and the nationality requirement without expansion.

The treaty does not authorize the U.S. government to add countries to the TN list unilaterally. Expanding TN eligibility to a third country would require negotiating a new trade agreement or amending USMCA, a process that involves all three signatory nations. No such negotiation is underway as of 2026, and no other country has been added to the TN framework since the category was established in 1994.

This is why TN status is fundamentally different from classifications like H-1B or O-1. Those categories are created by U.S. immigration law and apply to any nationality. TN status is created by a treaty, and the treaty names exactly two eligible countries. The distinction matters because it explains why no amount of professional achievement, U.S. ties, or employer need can add a third nationality to the TN eligibility list.

What TN Eligibility Requires Beyond Citizenship

Being a citizen of Canada or Mexico is necessary for TN status, but it is not sufficient. Applicants must also meet the regulatory requirements for TN classification:

1. Employment in a NAFTA/USMCA profession. The treaty lists approximately 60 professional occupations eligible for TN status. The job offer must fall within one of these listed professions — accountant, engineer, lawyer, scientist, teacher, and others. The full list appears in 8 CFR § 214.6(c) and Appendix 1603.D.1 to USMCA Annex 1603. A position that sounds professional but does not appear on the list does not qualify.

2. Required credentials for the profession. Each listed profession specifies minimum credentials, most commonly a baccalaureate degree in the field or a license to practice. A Mexican engineer must hold an engineering degree or licensure; a Canadian accountant must hold a degree or professional designation recognized in the field. The treaty defines what credentials satisfy the requirement for each profession.

3. A U.S. job offer in the listed profession. The applicant must have a job offer from a U.S. employer for work that corresponds to one of the NAFTA professions. Self-employment does not qualify. The employer need not file a petition with USCIS before the TN application — Canadian citizens apply directly at a port of entry or Canadian airport preclearance location; Mexican citizens apply for a TN visa at a U.S. consulate.

4. Intent to work temporarily. TN status is a nonimmigrant classification. Applicants must intend to work in the United States temporarily, not to immigrate permanently. Officers may question applicants about ties to their home country and the temporary nature of the assignment. Unlike H-1B, TN status does not permit dual intent — the applicant cannot simultaneously pursue permanent residence without risking denial.

The Application Process Differs by Nationality

Though Canada and Mexico are the only two countries on the TN eligibility list, the application process differs for nationals of each:

Canadian citizens do not need a visa to apply for TN status. They apply directly at a U.S. port of entry or at a Canadian airport preclearance facility by presenting a job offer letter, proof of Canadian citizenship, proof of credentials for the profession, and the applicable fee. Customs and Border Protection (CBP) adjudicates the application on the spot. If approved, the applicant receives TN status and may begin work immediately. No advance filing with USCIS is required.

Mexican citizens must apply for a TN visa at a U.S. consulate or embassy before traveling to the United States. The process involves scheduling a visa interview, presenting the job offer letter and credential documentation, and paying both the visa application fee and the TN petition fee. Once the TN visa is issued, the applicant presents it at a U.S. port of entry to receive TN status. The visa itself is not work authorization — it is permission to apply for TN status at the border.

The difference in process reflects broader visa policy between the United States and the two countries, not a difference in TN eligibility. Both nationalities must meet the same substantive requirements: listed profession, required credentials, U.S. job offer, and temporary intent.

Here's the Honest Answer: No Third Country Is Getting Added

Professionals from countries outside North America occasionally ask whether their country might be added to the TN list, especially if a trade agreement exists between their country and the United States. The answer is no. TN status is not a general treaty-trader category that expands with every bilateral trade agreement. It is specific to USMCA and its predecessor NAFTA. No other trade agreement the United States has signed — with Australia, South Korea, Chile, or any other nation — includes a TN-equivalent provision.

Adding a third country to the TN framework would require amending USMCA, which is a complex diplomatic and legislative process involving Canada and Mexico, not just the United States. There is no indication that any such amendment is under negotiation. Trade agreements since NAFTA have not included reciprocal temporary work provisions of the TN type. Professionals from non-NAFTA countries must use other work visa categories.

Comparison: TN Status vs. Other Work Visa Options

Bottom line: TN is the fastest and least expensive option for Canadians and Mexicans in NAFTA professions, but it is not available to any other nationality. Professionals from other countries must qualify under categories that do not have nationality restrictions.

What If You Are Not Canadian or Mexican?

If you do not hold Canadian or Mexican citizenship, you cannot use TN status, even if you meet every other requirement. Your options depend on your occupation, employer, and immigration goals:

H-1B status is the most common alternative for professionals. It requires a U.S. employer to file a petition, the position must require a bachelor's degree or higher, and you must hold the required degree. H-1B is subject to an annual cap of 85,000 visas (65,000 for bachelor's holders plus 20,000 for U.S. master's degree holders). Employers must enter the lottery in March for an October start date. H-1B permits dual intent, meaning you can pursue a green card while in H-1B status.

L-1 intracompany transferee status works if you have been employed by a foreign company with a U.S. affiliate for at least one year in the past three years. The U.S. employer (the affiliate) files a petition to transfer you to the U.S. location as a manager, executive, or specialized knowledge employee. There is no cap and no lottery, but the employer relationship must qualify.

O-1 status is for individuals with extraordinary ability in sciences, arts, education, business, or athletics. The standard is high — national or international recognition and sustained acclaim. O-1 requires detailed documentation of achievements, and the employer must file a petition. There is no cap, and O-1 is available to any nationality.

E-2 treaty investor status is available to nationals of countries with which the United States has a treaty of commerce and navigation. Over 80 countries qualify, including many outside North America. E-2 requires investment in a U.S. business, not just employment. The applicant must be coming to develop and direct the enterprise. E-2 is not the same as TN — it is a separate treaty-based category with its own eligibility list.

What If You Hold Dual Citizenship with Canada or Mexico?

If you are a dual citizen and one of your citizenships is Canadian or Mexican, you qualify for TN status based on that citizenship. You apply using your Canadian or Mexican passport and present proof of that citizenship when applying for TN status. The second citizenship does not disqualify you.

CBP and consular officers evaluate TN eligibility based on the citizenship you assert at the time of application. If you hold both Brazilian and Canadian citizenship, you apply for TN status as a Canadian citizen. You must present a Canadian passport and meet the TN requirements, but dual citizenship itself is not a barrier.

One caution: do not attempt to apply for TN status using a passport from a non-NAFTA country. Only Canadian and Mexican passports support TN applications. Presenting documentation from the wrong citizenship will result in denial.

What If You Are a Permanent Resident of Canada or Mexico But Not a Citizen?

Permanent residence in Canada or Mexico does not qualify you for TN status. The treaty requires citizenship, not residency. A Brazilian national with Canadian permanent residence (a "Canadian landed immigrant" or permanent resident card holder) cannot apply for TN status because they are not a Canadian citizen. The same applies to foreign nationals who are permanent residents of Mexico.

If you are a permanent resident of Canada or Mexico but hold citizenship in a different country, you must apply under a work visa category available to your nationality — most commonly H-1B, L-1, or O-1. Residency in North America does not change your nationality for immigration purposes.

Checking Your Citizenship and Profession Against the TN List

Before you assume TN status is unavailable or apply under the wrong category, verify two facts:

1. Are you a citizen of Canada or Mexico? Check your passport. Citizenship is the controlling factor, not where you live, work, or were educated.

2. Does your job offer fall within one of the NAFTA professions? Review the list in 8 CFR § 214.6 and Appendix 1603.D.1 to USMCA. The occupation must match one of the listed professions, and you must hold the credentials specified for that profession.

If both answers are yes, TN status is likely the fastest route to U.S. work authorization. If either answer is no, TN is not an option, and you must explore H-1B, L-1, O-1, or another classification.

The Role of USMCA in Maintaining the TN List

USMCA replaced NAFTA on July 1, 2020, but it preserved the TN provisions without substantive change. The list of professions, the credential requirements, and the nationality restriction remain the same. The only update was the agreement's name — references to "NAFTA professionals" are now references to "USMCA professionals," but the legal framework is identical.

The TN category was created to facilitate trade, not general immigration. The treaty allows Canadian and Mexican professionals to work in the United States temporarily to support cross-border business operations. That goal does not extend to professionals from other countries, even if those countries have strong trade relationships with the United States. The TN country eligibility list is fixed by treaty, and it will not expand unless the treaty is renegotiated.

When to Consult an Immigration Attorney

TN status appears straightforward — citizenship plus profession plus credentials. But issues arise:

• Your profession is borderline (it sounds like a NAFTA profession but the job duties do not match the treaty definition)
• Your credentials do not fit the standard pattern (foreign degree, professional experience in lieu of degree, self-taught expertise)
• You have a prior visa denial or immigration violation that could affect admissibility
• You are unsure whether your dual citizenship allows TN application
• Your employer is asking you to apply at the border without reviewing the documentation first

An immigration attorney can evaluate whether your situation meets TN requirements before you present yourself at a port of entry or consulate. Canadian applicants applying at the border receive an immediate decision — if CBP denies the application, you are turned away on the spot and there is no appeal. Mexican applicants go through consular processing, which allows more time to prepare, but a denial still closes the TN route. Getting the application right the first time matters.
