A TN visa lawyer helps Canadian and Mexican professionals — and the U.S. companies hiring them — use the USMCA (formerly NAFTA) professional category correctly: confirming the job fits a listed profession, matching the candidate’s credentials to it, drafting the employer support letter that decides most cases, and choosing the right filing route. Canadians can apply directly at the border; Mexicans apply for a TN visa at a U.S. consulate; and for workers already in the U.S., the employer can file Form I-129 with USCIS. Atlas Immigration Law prepares TN applications, renewals, and denial recoveries from our Dallas office for employers and professionals in all 50 states — flat fees quoted up front and a free 20-minute consultation to confirm the profession fit before anyone books a flight.
Key takeaways
TN status is limited to citizens of Canada and Mexico working in a profession on the USMCA list — engineers, accountants, scientists, certain medical roles, management consultants, and more — almost all requiring at least a bachelor’s degree in the field. There is no cap and no lottery, approvals come in up to three-year increments, and renewals can continue indefinitely as long as the stay remains genuinely temporary. The application is fast and inexpensive compared to the H-1B, but it is decided in minutes at a border or consulate, so the support letter and credential match must be airtight.
Who files what: three routes into TN status
- Canadian citizens — port of entry. No visa and no petition required: the professional applies in person to CBP at a border crossing or airport preclearance, carrying the employer’s support letter, proof of citizenship, and credentials, and can be admitted in TN status the same day.
- Mexican citizens — consulate. The professional applies for a TN visa at a U.S. consulate (with the same employer letter and credentials), then seeks admission at the border once the visa is issued.
- Either nationality, already in the U.S. — Form I-129. The employer files Form I-129 with USCIS to request a change of status or an extension, so the worker does not have to travel. Premium processing is available for an added government fee.
Whichever route is used, the substance is the same: this is an employer-supported status, not a self-petition. The employer letter — describing the professional role, the USMCA profession it fits, the candidate’s qualifying degree or credentials, and the temporary nature of the assignment — is the heart of the case. Spouses and children take TD status: they may live in the U.S. and study, but TD does not include work authorization.
Who qualifies: the profession list rules everything
TN eligibility is categorical. The offered job must fall within a profession on the USMCA appendix — the list summarized on the USCIS TN professionals page — and the applicant must hold the credential the list specifies for it, usually a bachelor’s degree or higher in the field, though a few categories accept alternative licenses or experience combinations (and one, management consultant, has its own well-litigated quirks). Software engineers, mechanical and civil engineers, accountants, economists, scientists, university teachers, and certain nurses and physicians (patient-care limits apply to physicians) are the workhorse categories for DFW employers.
Two traps recur. First, job-title mismatch: the duties, not the title, must fit the listed profession, and a “business analyst” doing engineering work needs the letter written around the actual engineering duties. Second, degree mismatch: the degree generally must be in the profession’s field, and adjacent degrees need a credential evaluation or a rethink of the category before the interview, not during it.
The TN process, step by step
| Stage | Who acts | What happens |
|---|---|---|
| 1. Category fit analysis | Attorney | Match the actual duties and the candidate’s credentials to a listed USMCA profession — or advise against applying. |
| 2. Support letter | Employer + attorney | A precise letter covering the role, profession, credentials, wage, and the temporary assignment period. |
| 3. Document package | Worker | Proof of Canadian or Mexican citizenship, degrees and transcripts, licenses, evaluations, résumé. |
| 4. Application | Worker or employer | Canadians apply to CBP at the border; Mexicans at a consulate; in-U.S. cases via the employer’s I-129 to USCIS. |
| 5. Decision | CBP / consulate / USCIS | Border and consular decisions are often same-day; I-129 timing varies with USCIS workloads. |
| 6. Renewals | Worker or employer | Up to three years per grant, renewable by re-application at the border or by employer-filed I-129 extension. |

Where TN cases go wrong
- Winging it at the border. A border refusal goes into the record and makes every later attempt harder. Treat the CBP window like a court appearance: rehearsed answers, organized documents, no improvising.
- Immigrant-intent friction. TN is a temporary status. A pending green card case does not automatically bar TN admission, but it invites hard questions — sequencing TN renewals around a green card strategy is exactly the kind of planning to do with counsel before travel, not at secondary inspection.
- Self-employment framing. TN does not permit working for yourself in the U.S.; the professional must provide services to a U.S. employer or client under a genuine engagement. Consultants need their arrangements papered correctly.
- Assuming TN is the ceiling. Professionals building a long-term U.S. career often move from TN to H-1B sponsorship or an employment-based green card; the right time to compare those tracks is at the first renewal, not the fifth.
Costs and timeline
The TN is one of the least expensive work statuses. Government fees are the CBP application fee at the border, the consular visa fees for Mexican applicants, or the I-129 filing fee (plus optional premium processing) for in-U.S. filings — current amounts are on the Form I-129 page and the relevant agency sites. Attorney fees are separate; Atlas charges a flat fee covering the category analysis, the support letter, the document package, and preparation for the interview or filing, quoted in writing before work begins.
Speed is the TN’s superpower: a well-prepared Canadian applicant can be working days after the offer letter, and consular timing for Mexican applicants depends mostly on appointment availability. In-U.S. I-129 changes and extensions run on USCIS clocks that vary — check current processing times — and workers nearing status expiration should start renewals early enough that a slow adjudication never leaves them out of status.
How Atlas Immigration Law helps
Atlas prepares TN cases to survive a five-minute inspection: a category analysis before anyone commits, a support letter that answers the officer’s questions in order, a documents binder the applicant can navigate under pressure, and a rehearsal of the interview itself. For employers, we standardize TN hiring across roles — engineering, finance, consulting — so each new hire is a template, not a scramble; for workers, we plan renewals and the eventual move to H-1B or permanent residence. Flat transparent fees, same-business-day responses, direct attorney access, and every case tracked in the Atlas Vision portal.

Frequently asked questions
Who qualifies for a TN visa?
Citizens of Canada or Mexico (permanent residents do not qualify) with a job offer from a U.S. employer in a profession on the USMCA list, holding the credential the list requires — usually a bachelor’s degree or higher in the field. Both the profession fit and the degree match are checked strictly.
Do Canadians need a visa for TN status?
No. Canadian citizens are visa-exempt and can apply for TN classification directly with CBP at a port of entry or preclearance airport, often receiving a same-day decision. Mexican citizens must first obtain a TN visa at a U.S. consulate before seeking admission.
Does the employer have to file anything for a TN?
For border and consular applications, the employer’s main task is the detailed support letter — no USCIS petition or Department of Labor filing is required. If the worker is already in the U.S. and wants to change or extend status without traveling, the employer files Form I-129 with USCIS.
How long can I stay in the U.S. on TN status?
TN status is granted in periods of up to three years and can be renewed indefinitely in practice, as long as each stay remains genuinely temporary and the professional role continues. There is no statutory maximum like the H-1B’s six years, but repeated renewals can draw questions about temporary intent.
Can I apply for a green card while on a TN visa?
TN is a temporary-intent status, so a green card process must be sequenced carefully — a pending permanent-residence case can complicate TN renewals and border re-entries. Many professionals switch to H-1B, which tolerates immigrant intent, before the green card stage. Get advice on ordering before filing anything.
Can my spouse work on a TD visa?
No. TD spouses and children may live in the U.S. and attend school, but TD status does not include work authorization. A spouse who needs to work would pursue their own independent status, such as an H-1B or TN of their own.
What happens if I’m refused TN status at the border?
A refusal is not a formal removal, but it is recorded and makes future attempts harder, so the response matters: identify exactly what the officer found lacking, fix the letter or the evidence, and re-apply deliberately — or pivot to an I-129 filing where an attorney can frame the record in writing.
