TN visa for Canadian and Mexican professionals

Who qualifies for TN status

TN is available to citizens of Canada and Mexico — citizenship, not permanent residence. A Canadian permanent resident who holds Indian citizenship cannot use TN.

Four things must all be true. You are a Canadian or Mexican citizen. The job is on the USMCA Appendix 2 professions list. You hold the specific credential that entry requires. And you have a U.S. employer or a signed contract with a U.S. entity — TN does not permit self-employment.

The occupation list is the constraint that decides most cases, and it is unforgiving. Appendix 2 names roughly sixty professions — Engineer, Computer Systems Analyst, Scientific Technician/Technologist, Accountant, Management Consultant, Economist, Graphic Designer, Architect, various scientists and health professionals, and others. If your role does not map onto one of them, TN is simply unavailable no matter how qualified you are. There is no catch-all.

Each entry specifies its own credential requirement, and they differ. Most require a baccalaureate or licenciatura degree. Some accept a post-secondary diploma plus three years of experience. Management Consultant uniquely accepts five years of experience in a related field in lieu of a degree. Scientific Technician/Technologist requires no degree at all but demands theoretical knowledge in a specific discipline plus the ability to solve practical problems in it, and requires working in direct support of a professional in that discipline.

Two occupations account for a disproportionate share of refusals. Computer Systems Analyst is not a general-purpose software engineering category — a role that is primarily programming or software development does not fit it, and officers know the distinction. Management Consultant must be genuinely consultative: providing services under contract to improve an organization's operations, not filling a permanent operational management role.

Finally, TN requires nonimmigrant intent. Unlike H-1B and L-1, TN carries no dual intent. Pursuing a green card while holding TN status is not automatically fatal, but it creates real risk at each entry and each renewal, because you must be able to demonstrate an intention to depart. This is the most consequential difference between TN and its alternatives, and it is why people with permanent-residence plans often move from TN to H-1B or O-1A.

• Canadian or Mexican citizenship — permanent residence in those countries does not qualify.
• The role must map onto a specific USMCA Appendix 2 profession; there is no catch-all category.
• Credentials must match what that specific entry requires, which varies by profession.
• Self-employment is not permitted; a U.S. employer or contract is required.
• No dual intent — TN status assumes you will depart.

What a TN application needs

TN is the lightest-weight employment category in U.S. immigration, but light does not mean casual. The whole case is usually decided by an officer reading one letter.

The employer support letter is the document. It must state the Appendix 2 profession by name, describe duties that plainly fall within that profession, state the credential the beneficiary holds and how it satisfies the requirement for that entry, specify the length of the engagement, state the salary, and confirm the beneficiary is not being self-employed. A letter that describes duties in general business language without naming the profession is the most common reason a well-qualified applicant is refused.

Credentials. Degree certificates and transcripts. For foreign degrees other than Canadian or Mexican, a credential evaluation. For professions with a licensing requirement, the license. For the experience-based entries, detailed employment letters documenting the years and the nature of the work.

Citizenship. Passport for Canadians and Mexicans; Canadians do not need a visa foil but do need to establish citizenship at the port of entry.

Evidence of nonimmigrant intent where it may be questioned: ties abroad, the temporary nature of the engagement, and a defined end date. A letter stating an indefinite permanent position invites the question.

A note on framing that matters more here than anywhere else: the duties described must match the profession claimed, not the internal job title. A company that calls the role "Software Engineer" but whose actual duties are systems analysis should describe the duties accurately and claim Computer Systems Analyst; a company whose engineer really does write software should recognize that TN may not be available and consider H-1B or another route rather than stretching the description. Misdescribing duties at a port of entry has consequences well beyond a refusal.

How to get TN status

The process differs by nationality, and the Canadian route is dramatically faster than anything else in U.S. employment immigration.

Canadians may apply directly at a U.S. port of entry or a pre-clearance facility, presenting the passport, the employer support letter, and credentials to a CBP officer. No USCIS petition, no consular appointment, no visa foil. The decision is made on the spot. It is possible to be admitted in TN status the same day the job offer is signed — which also means there is no opportunity to correct a weak letter before an officer reads it.

Mexicans apply for a TN visa at a U.S. consulate, with an interview, and then seek admission with the visa. The documentary requirements are the same; the process adds consular scheduling.

Either nationality may alternatively have the U.S. employer file Form I-129 with USCIS for a change of status or an extension from inside the United States. This route is slower and costs the full I-129 fee stack, but it avoids international travel and produces a USCIS approval notice rather than relying on a single officer's assessment at the border. For a candidate whose case is arguable, the petition route is often the safer choice.

TN is granted for up to three years and can be renewed indefinitely in three-year increments. There is no maximum period of stay — which is unusual, and one of TN's real advantages.

The absence of dual intent shapes long-term use. Every renewal and every reentry is an opportunity for an officer to examine intent, and a pending green-card process is discoverable. People who decide to pursue permanent residence commonly transition to H-1B or O-1A first.

Spouses and children hold TD status. TD dependents cannot work, though they may study — a significant drawback compared with the L-2, where the spouse is employment-authorized incident to status.

What TN status costs

TN is by a wide margin the cheapest employment route into the United States. A Canadian applying at a port of entry pays a modest CBP application fee; a Mexican applicant pays the Department of State nonimmigrant visa application fee. There is no ACWIA fee, no Fraud Prevention fee, and no statutory surcharge.

Where the employer files Form I-129 instead — for a change of status, an extension, or because the case is worth having adjudicated on paper — the full I-129 fee stack for a TN petition applies, including the Asylum Program Fee at the applicable tier, with premium processing optional. Those amounts are in the fee calculator.

Legal cost is correspondingly low, and it buys something specific: getting the support letter and the occupation mapping right before an officer sees them. Because the Canadian port-of-entry route gives you no second chance and no appeal, the preparation is worth more here relative to the filing than in almost any other category.

VisaSherpa charges a flat fee with a refund if a filed petition is denied. That is a fee policy, not an outcome guarantee, and it does not extend to a discretionary refusal at a port of entry.

Common TN refusal and RFE triggers

TN problems surface as on-the-spot refusals at the border more often than as written Requests for Evidence, which makes prevention the only real strategy.

• The role does not map onto an Appendix 2 profession — most often a software engineering role presented as Computer Systems Analyst.
• Management Consultant claimed for an operational role. The entry contemplates consultative services, not permanent line management.
• Credential mismatch — the degree is in a field the profession's entry does not accept, or a foreign degree lacks an evaluation.
• Support letter written in generic business language without naming the profession or connecting duties to it.
• Self-employment, or an arrangement where the beneficiary effectively controls the petitioning entity.
• Immigrant intent apparent from a pending green-card process, an indefinite permanent offer, or severed ties abroad.
• Duties that drift between renewals, so the role no longer matches the profession originally claimed.
