TN Visa Guide 2026: USMCA Professions, Fees & Border

What the TN Classification Is

The TN classification is a creature of a trade agreement rather than of a standalone immigration statute, and the difference shows in how it is administered. There is no lottery, no annual cap, no prevailing wage determination and no labor condition application. The adjudicating officer has a written table of professions and a written list of required letter contents, and the decision turns on whether the applicant's job and credentials match them. That is why a TN can often be approved the same day an eligible person walks up to a pre-clearance booth, while an H-1B petition for the same person takes months and a filing fee measured in thousands of dollars.

The classification is also narrower than it first appears. The applicant must be coming to perform prearranged business activities for a US employer or entity — the regulation contemplates a letter from the prospective US employer or from a foreign employer providing prearranged services to a US entity — and the activities must be at a professional level as defined by the agreement. A degree alone is not enough; the job itself has to sit in one of the listed professions. And because the TN is expressly temporary, it is not the right vehicle for someone with a settled intention to remain permanently, a point the comparison section below takes up directly.

Spouses and unmarried minor children may accompany the TN worker in TD classification for the same period, though TD dependents may not accept employment unless they independently obtain work authorization.

The Two Entry Routes: Canada and Mexico

The regulation treats Canadian and Mexican citizens differently, and the difference is substantial: for Canadians the TN is an admission process, while for Mexicans it is a two-step visa process.

Both routes end in the same place: admission under the classification symbol TN for a period not to exceed three years, with a confirming document bearing the legend "multiple entry." That legend matters for people who commute across the border or travel to Mexico or Canada for business during the period of stay — multiple entry means the worker may depart and be readmitted for the remainder of the authorized period.

The regulation also provides an explicit readmission path. A TN nonimmigrant with a valid unexpired Form I-94 may be readmitted for the remainder of the authorized period without presenting the employer letter or supporting documentation and without paying the prescribed fee, provided the original intended professional activities and employers have not changed. If the I-94 has been lost but the period has not lapsed, alternate evidence — a fee receipt for a prior TN admission, a prior TN admission stamp in the passport, or a confirming letter from the US employer for Canadians; a valid unexpired TN visa plus evidence of previous admission for Mexicans — supports issuance of a replacement I-94 for the remaining period.

At the Port of Entry: Inspection, the I-94 and Withdrawal

The route table above ends where the paperwork starts. A TN admission is decided by an officer at a primary or secondary inspection point, and the sequence is the same at a land border, at an international airport and at a pre-clearance site on Canadian soil.

Primary inspection is a records check. The officer confirms citizenship, asks the purpose of the trip, and decides whether the case can be resolved at the window or has to move to secondary. Most first-time TN files go to secondary, not because anything is wrong but because secondary is where the letter, the degree and the evaluation can be read without holding up a lane. A referral is not an adverse finding.

Secondary inspection is where the adjudication happens. Hand over, in this order: passport or citizenship evidence, the employer letter, the original degree or licence, and the credentials evaluation if the degree was earned outside Canada, Mexico or the United States. Keep a second complete set. An officer can only weigh what is in front of them, and a letter that exists as an email attachment the applicant cannot produce is not documentation under 8 CFR 214.6(d)(3).

The I-94 is the admission. The electronic arrival record, not the visa and not the passport stamp, carries the classification symbol and the date the stay ends. CBP creates the record from the traveller's documents; at land borders travellers now receive an electronic I-94 instead of a paper stub and can print a copy from the CBP I-94 website or the CBP Link app. Before leaving the port, check three fields: the class must read TN, the admit-until date must match the period requested, and the record must carry the multiple entry legend. A mistake found a year later is far harder to correct than one caught at the counter.

The fee at the land border is $30 — a $6 I-94 fee plus the $24 HR-1 surcharge — assessed on and after September 30, 2025. At air and sea ports no I-94 fee is charged, because no I-94 application is required and the record is generated from the manifest. If the record is later lost, a replacement is requested on Form I-102 at $560.

Refusal is not a single outcome. An applicant who cannot satisfy the officer may be permitted to withdraw the application for admission under 8 CFR 235.4. That regulation is explicit that withdrawal is discretionary, that it confers no right, and that permission "should not normally be granted unless the alien intends and is able to depart the United States immediately." A withdrawal avoids removal proceedings, but it is not an approval and it does not cure a defective letter. Where withdrawal is not permitted, the officer proceeds to a formal inadmissibility determination, which carries consequences for future travel that a withdrawal does not.

The practical consequence is that a weak file should be fixed before the trip rather than argued at the counter. CBP designates 14 ports of entry for optimized first-time TN and L-1 processing, four of them pre-clearance locations at Calgary, Toronto Pearson, Montreal Trudeau and Vancouver, staffed daily from early morning into the evening. Any port along the Canadian border will still accept a TN filing, but the designated ports are resourced for it, and a complex file presented at the end of a shift is being presented to an officer with less time.

The USMCA Profession Table

The table below reproduces the qualifying professions and minimum requirements from Appendix 2 to Annex 16-A of Chapter 16 of the USMCA, as codified at 8 CFR 214.6. The regulation reproduces the appendix in four unnumbered groups — general professions, medical and allied professions, scientists, and teachers — with 63 entries in total. Note that a business person in this appendix may also perform training functions relating to the profession, including conducting seminars.

Three definitions inside the table decide many borderline cases. A post-secondary diploma is a credential issued, on completion of two or more years of postsecondary education, by an accredited academic institution in Canada or the United States. A post-secondary certificate is a certificate issued on completion of two or more years of postsecondary education by the federal government of Mexico or a state government in Mexico, by an academic institution recognized by the federal government or a state government, or by an institution created by federal or state law. A state, provincial or federal licence is any document issued by a state, provincial or federal government, or under its authority, but not by a local government, that permits a person to engage in a regulated activity or profession.

The footnotes carry real requirements of their own. A scientific technician or technologist does not need a degree, but must hold theoretical knowledge of one of the listed disciplines and be able to solve practical problems in it or apply its principles to basic or applied research; footnote 6 adds that the work must be in direct support of professionals in that discipline, which is why a general science graduate in an unrelated role does not fit. A medical technologist under footnote 7 must be entering to perform laboratory, chemical, biological, hematological, immunologic, microscopic or bacteriological tests and analyses for diagnosis, treatment or prevention of disease. And Biologist includes Plant Pathologist under footnote 8, which is easy to miss when scanning for a matching title.

Two entries in this table deserve their own treatment rather than a row. The management consultant entry is the only general profession a five-year experience record can satisfy without a degree, and it is the most heavily scrutinized; the next section sets out what a file has to contain. The computer systems analyst entry is the one most often misapplied to jobs whose real title is software engineer or developer, and it shares the same problem: the duties have to match the listed occupation.

Two habits prevent most mapping errors. Start by reading the entry itself rather than the employer's job title, because the title reflects a pay band while the entry reflects the duties performed. Then treat the table as closed: an occupation that is not printed in it is not eligible for TN status however strong the degree, the salary or the employer, so a product manager, a marketer or a trade worker cannot be relabelled into a category. Those candidates belong in H-1B, L-1 or O-1.

The Support Letter and Required Documents

The regulation specifies exactly what documentation the applicant must present, and exactly what the support letter must say. Both Canadian and Mexican applicants must present proof of citizenship and documentation sufficient to satisfy the officer that the applicant is seeking entry to perform business activities at a professional level for a US employer or entity and meets the criteria to perform at that level. That documentation may be a letter from the prospective US employer or from the foreign employer, and it must be supported by diplomas, degrees or membership in a professional organization.

Degrees earned at an educational institution not located in Canada, Mexico or the United States must be accompanied by an evaluation from a reliable credentials evaluation service that specializes in evaluating foreign educational credentials. This is a hard requirement rather than a courtesy, and applicants with third-country degrees who arrive without the evaluation are routinely refused.

The letter must fully affirm all five of the following, and the checklist below is the one to draft against:

• The profession of the applicant under Appendix 2 to Annex 16-A of Chapter 16 of the USMCA, named as it appears in the table.
• A description of the professional activities, including a brief summary of daily job duties where appropriate, in which the applicant will engage for the US employer or entity.
• The anticipated length of stay, which should match the period you are asking to be admitted for.
• The educational qualifications or appropriate credentials demonstrating that the applicant has professional-level status.
• The arrangements for remuneration for the services to be rendered.

A letter missing any one of the five is the single most common cause of refusal, and because TN adjudication happens at a booth or a consular window there is usually no opportunity to cure the omission on the spot — you are refused, and you come back with a corrected letter. Our visa document checklist tool builds the packet against these five elements, and visa application tracking covers consular appointment timing for Mexican applicants.

Management Consultant and Computer Systems Analyst Files

Two entries in the general group produce a disproportionate share of difficult adjudications. Management consultant is the only profession a five-year experience record can satisfy without a degree. Computer systems analyst is the entry most often claimed by people whose actual title in the US market is something else. Both are legitimate, and both fail for the same reason: the file describes a job that is not the listed occupation.

Management consultant. The appendix accepts a baccalaureate or licenciatura degree, or "equivalent professional experience as established by statement or professional credential attesting to five years experience as a management consultant, or five years experience in a field of specialty related to the consulting agreement." The experience route is real, and it is also why the category is examined closely: the officer has to decide whether the employer is buying advice or buying a person. Two questions do most of the work. Does the engagement have a defined problem, a deliverable and an end date? And does the consultant stay on the consultancy's payroll, outside the client's reporting line and headcount?

The difference between a letter that survives and one that does not is usually visible in a single sentence. A weak letter reads: "will assist the client's operations team with various projects as needed, reporting to the Vice President of Operations, for an initial period of three years." That describes a temporary employee. A strong letter identifies the consultancy, the client, the specific engagement and its duration, the deliverable the consultancy owns, and the fee arrangement — for example a nine-month review of a distribution network producing a cost model and an implementation plan, billed on milestones, with the consultant remaining an employee of the consultancy and not filling a position in the client's headcount.

Computer systems analyst. The credential route is a baccalaureate or licenciatura degree, or a post-secondary diploma or post-secondary certificate plus three years of experience. The second route is where files break, because both terms are defined: a post-secondary diploma is a credential issued on completion of two or more years of postsecondary education by an accredited academic institution in Canada or the United States, and a post-secondary certificate is issued on completion of two or more years at a Mexican institution recognized by the federal government or a state government. A vendor certification and a one-year programme are neither.

The duties matter as much as the credential. The listed occupation is analysis: requirements gathering, systems and data design, specification writing, testing criteria, and liaison between users and developers. A letter whose duty list is entirely hands-on coding describes a programmer, and a programmer is not on the appendix. The same discipline applies to the scientific technician entry, which requires theoretical knowledge in a listed discipline plus the ability to solve practical problems or apply its principles to research, with the additional requirement that the work be in direct support of professionals in that discipline.

Neither entry is a loophole, and neither is closed to a well-documented case. But the officer reads the appendix first and the letter second. If the duties cannot be matched to the listed occupation in one page, the problem is the job description rather than the officer.

TN Fees by Route

TN is the least expensive US work classification, but there is no single "TN fee". What you pay depends on nationality, on whether the case is decided at a port of entry or by USCIS, and on the visa validity you ask a consulate for. The table prices each route separately, using the fee schedule in 8 CFR 106.2, the CBP fee provisions in 8 CFR 103.7 and the State Department's Mexico reciprocity schedule.

Read as totals, the routes separate cleanly. A Canadian applying at a land border pays $80 in government fees and nothing else; the same applicant arriving by air pays $50. A Mexican applicant pays $185 plus reciprocity — $264 for a 12-month visa or $542 for 48 months — and then faces the same border admission a Canadian does. The USCIS route is the expensive one: $965 online, or $3,930 with premium processing added.

Three things TN does not carry are worth naming, because they are what make the comparison with H-1B lopsided. There is no labor condition application, and therefore no LCA filing, wage attestation or public access file. There is no permanent labor certification at the front end. And there is no cap registration step, so no registration fee and no lottery to enter. The employer's cost is the filing fee and counsel's time, and for a Canadian at the border it is neither.

Two cautions on the figures. The reciprocity amount is set by the State Department's Mexico schedule and is tied to the validity period requested, so it moves when that schedule changes. And the online discount applies only where USCIS accepts an online filing for that form, which makes the paper figure the safe budget number. Our visa fee calculator totals the stack for a specific route.

Extensions, New Employers and Concurrent Jobs

An initial TN admission runs up to three years, and the confirming document is multiple entry. Three mechanisms continue it, and choosing between them is the part applicants get wrong.

1. Extension with USCIS. A US employer of a worker in valid TN status, or a US entity where the worker is employed by a foreign employer, may file Form I-129. The beneficiary must be physically present in the United States when the form is filed, and the extension may be approved for a maximum of three years. If the worker has to leave while the petition is pending, the petitioner may ask USCIS to notify the consular office, or the DHS-designated port where a visa-exempt worker will apply, of the approval.
2. New admission at the border. A TN worker who has not violated status may apply at a DHS-designated port of entry before the prior period expires for a new three-year admission, supported by a fresh letter meeting the same requirements and the prescribed fee. Mexican citizens must present a valid passport and a valid, unexpired TN visa.
3. Consular re-application. A Mexican citizen may present new documentation to a consular officer in support of a new TN visa application, which is the route to use when the visa itself has expired or the validity period needs to change.

There is no specific limit on the total period a person may hold TN status, provided the worker continues professional activities for a US employer or entity at a professional level and otherwise maintains status. That is a meaningful contrast with the H-1B, which carries a six-year ceiling absent an approved labor certification or a pending green card.

Changing or adding an employer is the operation most often gotten wrong. A TN nonimmigrant who seeks to change or add a US employer during the period of admission must have the new employer file Form I-129 with supporting documentation, including a letter describing the services, the time needed to render them and the terms of remuneration, and employment with the different or additional employer is not authorized before approval. The regulation preserves an alternative: the worker may apply at a port of entry for readmission to present documentation from a different or additional US or foreign employer, meeting the same letter requirements. A transfer to a branch or office of the same employer requires no action at all, while a transfer to a separately incorporated subsidiary or affiliate does require the petition or the readmission.

Concurrent employment. Holding two TN jobs at once is permitted, but each employer has to be authorized on its own. The State Department's guidance treats the TN visa as not employer-specific and allows multiple concurrent employers, with each employer annotated on the visa; the regulatory route is the change-or-addition procedure, employer by employer. In practice that means two letters and two filings or admissions, and no work for the second employer until its own approval exists. An officer who finds a second job that was never documented is looking at unauthorized employment rather than an administrative oversight.

Commuting and short trips. The multiple entry legend is what makes a cross-border commute work. A TN worker with a valid unexpired I-94 may be readmitted for the remainder of the authorized period without presenting the letter again and without paying the fee again, provided the original activities and employers have not changed. The moment the employer changes, that free readmission stops applying: the regulation directs that the 8 CFR 106.2 fee be remitted by Canadian citizens on an admission based on a new employer's letter.

When the job ends. Neither the regulation nor the State Department's guidance requires the worker to report a termination, and no notification form exists for it. Stopping work is not by itself a status violation, but the classification then authorizes nothing: any new employment needs its own approval. A worker who assumes a TN admission doubles as a general work permit has misread what was granted.

One timing rule cannot be fixed afterwards: file or travel before the I-94 expires. A late filing does not preserve a period that has already run out, and a worker whose record has lapsed is applying for admission from outside status rather than extending it.

TD Dependents

The spouse and unmarried minor children of a TN nonimmigrant may be admitted, readmitted, or granted a change of status or extension for the same period of time granted to the TN nonimmigrant, and are classified as TD. A request for a change of status to TD or an extension of stay may be made on the appropriate form with filing fees and evidence of the principal's current TN status.

Three rules govern TD dependents. A TD nonimmigrant must present a valid, unexpired TD nonimmigrant visa unless otherwise exempt. Their confirming documentation bears the "multiple entry" legend, and there is no fee required for their admission. And TD dependents shall not accept employment in the United States unless otherwise authorized — TD is not work-authorized on its own, and there is no incidental work permission to apply for, so a spouse who intends to work has to qualify for a work classification in their own right.

Two details trip families up at the counter. The dependent class covers a spouse and unmarried children under 21; once a child passes that age the definition no longer fits, so the next extension or admission has to be planned rather than assumed, and it is worth raising with counsel before the birthday. And the dependent's admission has to coincide with the principal's: a TD cannot be admitted for a period longer than the TN worker was granted, which is why families travelling separately should carry the principal's I-94 and approval notice.

TD dependents may study in the United States — full-time, at any level — without a separate student status, which makes the classification unusually family-friendly on everything except earned income. Extending a dependent's stay inside the United States uses Form I-539 at $470; the alternative is to travel with the principal and be admitted at the port.

TN or H-1B: Which Classification Fits?

For a Canadian or Mexican professional whose occupation sits on the USMCA table, the TN is almost always the better first move, and the H-1B becomes relevant only in specific situations.

The decisive row is dual intent. Because the TN classification is temporary by design and does not carry the H-1B's dual intent protection, a TN holder who has a pending immigrant petition, or who has taken steps toward permanent residence such as filing an I-140, can face a harder question at a renewal or readmission than an H-1B holder would. Applicants in that position should plan the classification strategy deliberately rather than defaulting to repeated TN renewals. For the mechanics of the H-1B route, see our H-1B visa guide, H-1B amendments guide and H-1B extension guide; our TN USMCA border guide covers the port-of-entry mechanics in more depth.

Why TN Applications Get Refused

Refusals cluster in five places, and four of them are fixable before you present yourself.

• The job is not on the list, or the credential is short. The profession table is closed. A marketing manager, a general business analyst or a project manager is not a listed profession regardless of degree, and a person holding a three-year diploma cannot claim a baccalaureate-equivalent entry that requires a four-year degree.
• The support letter is incomplete. Missing any of the five required affirmations — profession, activities, length of stay, credentials, remuneration — is a straightforward refusal.
• Third-country degrees without an evaluation. Degrees from institutions outside Canada, Mexico and the United States must be accompanied by a credentials evaluation from a service specializing in foreign credentials.
• Management consultant engagements that look like permanent staffing. The entry is heavily scrutinized, and an engagement that reads as filling a standing internal role rather than providing consulting services will not survive it.
• Arriving with the wrong route or the wrong fee. A Mexican citizen cannot be admitted on an expired visa, and a Canadian who could have been admitted at the border but filed an I-129 instead has spent $965 and several weeks to reach the same result. The reverse mistake is worse: presenting at a land border without the credentials evaluation the file depends on.

When a refusal happens, the response matters more than the refusal itself. Ask the officer which element failed and write it down while it is fresh; the answer is usually one of the five letter elements rather than a judgment about the person. Do not re-present an identical package at the next port in the hope of a different officer — the refusal is recorded in CBP systems and the next officer can see it, which makes a second identical refusal harder to explain than the first.

1. Record the stated ground precisely, including any regulation or letter element the officer cited.
2. Fix the document that failed: reissue the letter with the missing element, obtain the evaluation, or rename the profession in the letter to the one the duties actually match.
3. Confirm the encounter was recorded as a withdrawal, and that no removal order or expedited removal was entered against the record.
4. Re-apply with the corrected package, leaving enough margin that a second encounter does not strand a start date.

The defense is to treat the letter as a compliance document rather than a cover letter: name the profession exactly as it appears in the table, describe duties that map to that profession, state the stay and the pay, and attach the credential. Our visa eligibility checker screens the occupation against the table before you book anything, and visa stamping guidance covers consular appointment logistics for applicants who need a visa stamp.
