If you’re a Canadian or Mexican citizen, the TN classification is often the fastest way to work legally in the United States. There’s no lottery, no annual cap, and for Canadians no visa stamp. It comes from the United States-Mexico-Canada Agreement (USMCA), which replaced NAFTA in 2020 but kept the TN category.
The catch is that TN is narrow. Your job has to fit one of the professions on a specific list, and you need the right qualifications for that profession. This guide walks through how it works. It’s general information, not legal advice.
Who can get TN status
- Citizens of Canada or Mexico (permanent residents of those countries don’t qualify)
- With a job offer from a US employer, or a contract with a foreign employer to work in the US
- In a profession listed in USMCA Appendix 2 to Annex 16
- With the degree, license or experience required for that profession
Self-employment isn’t allowed. You must work for a US employer or a foreign employer under contract.
The professions list
The list includes more than 60 professions. Some of the most common:
| Group | Examples |
|---|---|
| Technology and engineering | Engineer, computer systems analyst, mathematician, statistician |
| Business | Accountant, management consultant, economist, industrial designer |
| Science | Biologist, chemist, physicist, geologist, research assistant (at universities) |
| Healthcare | Registered nurse, physician (teaching or research), pharmacist, physiotherapist, dentist |
| Education | College, university and seminary teachers |
| Other | Architect, lawyer, librarian, urban planner, scientific technician |
Most listed professions need at least a bachelor’s degree or licenciatura. A few, such as management consultant or computer systems analyst, allow certain alternatives like a post-secondary diploma plus experience.
Common issue: Job titles like “software developer” aren’t on the list. Many developers qualify as “engineer” or “computer systems analyst,” but the duties in your offer letter must match the listed profession, and your degree should fit. Border officers look closely at this.
What you need
- Proof of citizenship, such as a passport
- A detailed job offer letter from the US employer describing duties, start date, length of employment, pay, and how the role fits the TN profession
- Degree certificates and transcripts, with evaluations for foreign degrees if needed
- Professional licenses where required
- Proof of experience if the profession requires it
The offer letter is the heart of the application. It should be on company letterhead and clearly show the job is temporary, even if it’s renewable.
Canadians: applying at the border
Canadian citizens don’t need a visa stamp. You present your documents to a Customs and Border Protection officer at a land port of entry or at a preclearance location in a Canadian airport, pay the fee, and, if approved, receive an I-94 record showing TN status.
Your employer can also file Form I-129 with USCIS in advance. This gives a decision before you travel, which some people prefer for certainty or for changing status from inside the US.
Mexicans: applying at a consulate
Mexican citizens apply for a TN visa at a US embassy or consulate, with Form DS-160, an interview and the visa fee. After the visa is issued, you present it at the border to be admitted in TN status. No USCIS petition is required.
Length of stay and renewals
TN status is granted for up to three years. You can renew as many times as you want, either by applying again at the border or consulate or by having your employer file an extension with USCIS. There’s no overall maximum, but the job must remain temporary in nature.
Spouses and children
Spouses and unmarried children under 21 can come in TD status. They can study but cannot work. If they are also Canadian or Mexican citizens with qualifying jobs, they may get their own TN.
Changing jobs
TN status is tied to your employer. If you change employers, you need a new TN application based on the new job. You can apply at the border or have the new employer file with USCIS. You can hold TN status with more than one employer at the same time if each approves it.
If you lose your job
Like other work visa holders, TN workers generally have a grace period of up to 60 days, or until the I-94 expires if sooner, to find a new job, change status or leave.
TN and the green card
TN is a nonimmigrant status and doesn’t allow “dual intent.” Many TN holders do move on to green cards, but timing matters. Filing a green card application can make it harder to renew TN at the border, because officers may decide you no longer intend a temporary stay. Some people switch to H-1B before filing, or time a green card filing carefully with legal advice.
Tips for a smooth application
- Match your offer letter duties to the official profession description
- Carry original degrees and transcripts, not just copies
- Bring a short, clear summary of your role that you can explain in plain words
- Apply during quieter hours at the border if possible
- Keep copies of your I-94 and approval notices for future renewals, driver’s licenses and tax filings
TN compared with H-1B
| TN | H-1B | |
|---|---|---|
| Nationality | Canada or Mexico only | Any |
| Lottery | No | Usually |
| Where to apply (Canadians) | Border or preclearance | USCIS petition |
| Maximum stay | No limit, three-year periods | Generally six years |
| Dual intent | No | Yes |
| Spouse can work | No | Only with certain H-4 EADs |
For many Canadians and Mexicans, TN is the quickest and cheapest way to start working in the US. If your long-term goal is a green card, plan the switch early.
Sample TN offer letter outline
Border officers read offer letters closely. A strong letter usually includes:
- Company background: what the company does, size, locations
- Job title and TN category: for example, “Engineer (USMCA Appendix 2)”
- Detailed duties: how your daily work matches the listed profession
- Qualifications required: the degree or license needed for the role
- Your qualifications: your degree, license and relevant experience
- Terms: start date, length of employment (up to three years), salary and benefits
- Temporary nature: a statement that the role is for a temporary period
- Signature: from a manager or HR representative
Keep the letter consistent with your resume and LinkedIn profile.
What happens at the port of entry
For Canadians applying at the border or a preclearance airport:
- Go to the CBP secondary inspection area for TN applications
- Present your passport, offer letter, degree and supporting documents
- Answer questions about your job and qualifications
- Pay the fee
- If approved, check your I-94 record online a few days later
If the officer denies the application, ask for the reason. Often it’s a mismatch between the job duties and the profession, which can be fixed with a better letter.
Tips for common professions
| Profession | What officers often check |
|---|---|
| Engineer | Engineering degree in a relevant discipline; engineering duties, not just coding |
| Computer systems analyst | Analysis and design duties, not pure programming |
| Management consultant | Advisory role, often temporary project-based work; degree or experience requirements |
| Scientific technician | Must work directly with a professional in a supporting role |
| Registered nurse | License and credentials; state licensing rules |
Keeping your status
- Work only for the employer listed
- File extensions before your I-94 expires
- Keep proof of your home-country ties if you plan to stay temporary
- Update your I-94 each time you re-enter; the date shown on your latest I-94 is what counts
Planning for the long term
If you want to live in the US permanently, talk to an immigration attorney early about switching to H-1B, O-1 or a green card route. Planning ahead helps you avoid problems with TN renewals at the border.
