Quick answer: To hire a Canadian or Mexican professional on a TN visa, a US employer needs a genuine, pre-arranged job in one of the professions listed under the USMCA (formerly NAFTA). The worker must hold the degree or credentials that profession requires, and the employer gives them a detailed job offer letter. The TN doesn’t need “sponsorship” the way the H-1B does: there’s no lottery, no labor certification and usually no USCIS petition. Canadians can apply at the US border, and Mexicans apply for a TN visa at a US consulate. Each TN period is up to three years and can be renewed.
This guide covers what employers must provide, the costs and the common mistakes. Last reviewed October 2026.
TN requirements for US employers
| Requirement | What it means |
|---|---|
| Qualifying profession | The job must match one of about 60 USMCA professions (engineer, accountant, scientist, registered nurse, management consultant and others) |
| Professional-level job | The role must actually require that professional’s skills, not a related lower-level job |
| Worker credentials | The worker holds the required degree or license (for example a bachelor’s degree for engineers) |
| Pre-arranged employment | A specific job with a US employer; self-employment isn’t allowed |
| Temporary stay | Up to 3 years per admission, renewable; the worker must not intend to immigrate |
Does a TN visa require sponsorship?
Not in the H-1B sense. Employers don’t enter a lottery, file a Labor Condition Application or go through PERM. What the employer must do is offer a real job and provide a support letter. For Canadians, the worker usually brings this letter to the border. An employer can choose to file Form I-129 with USCIS instead, for example to get approval before the worker travels.
The employer support letter
- The USMCA profession category the job falls under
- A detailed description of duties showing the professional level
- The start date and expected length (up to 3 years)
- Salary and benefits
- The educational qualifications or credentials required, matched to the worker’s own
How the application works
| Canadian citizens | Mexican citizens | |
|---|---|---|
| Where | At a US port of entry or preclearance airport | At a US embassy or consulate |
| Visa needed? | No visa; TN status given at the border | Yes, a TN visa (DS-160 and interview) |
| Government fee | CBP processing fee at the border | $185 visa application fee, plus the $250 integrity fee where collected |
| Alternative | Employer files Form I-129 with USCIS | Employer files Form I-129 (optional) |
Employer obligations after hire
- Complete Form I-9 using the TN I-94 record.
- Keep the job consistent with the TN letter. Material changes may need a new application.
- Track the I-94 end date and renew before it expires.
- Dependants (spouse and children) come in TD status and can’t work.
Common mistakes
- Using a profession title that doesn’t match the real duties, for example calling an IT support role “computer systems analyst”
- Degrees in an unrelated field
- Letters that sound permanent, such as “indefinite employment”
- Starting a green card case without planning around the TN’s no-immigrant-intent rule
TN vs H-1B for employers
| TN | H-1B | |
|---|---|---|
| Lottery | No | Yes. See H-1B 2026 |
| Nationalities | Canada and Mexico only | Any |
| Dual intent | No | Yes |
| Maximum time | Renewable in 3-year periods | 6 years, with some extensions |
FAQ
Can a TN worker be self-employed or a contractor?
Self-employment isn’t allowed. A worker can be employed by a staffing company or a foreign employer providing services to a US client in some cases, but the arrangement needs careful documentation.
Is there a cap on TN visas?
No. There’s no annual limit.
Can a TN worker get a green card?
Yes, but because TN doesn’t allow immigrant intent, timing matters. Many people switch to H-1B first. Get legal advice before filing.
How long does TN approval take?
Canadians usually get a decision at the border the same day. Mexican applicants depend on consulate appointment waits.
