TN vs H-1B1 Visa: Key Differences Explained
If you're a Canadian, Mexican, Chilean, or Singaporean professional considering work in the U.S., the TN visa and H-1B1 are two of the most accessible paths available to you. Both bypass the H-1B lottery entirely, but they serve different nationalities and come with meaningfully different rules around renewals, job changes, and long-term planning.
Canadians and Mexicans often find the TN visa to be the simplest and fastest option. Chilean and Singaporean nationals typically look at the H-1B1, which is their closest equivalent and the only free trade visa available to them.
| TN Visa | H-1B1 Visa | |
|---|---|---|
| Eligibility | Canadian and Mexican citizens only; USMCA-listed profession required | Chilean and Singaporean citizens only; qualifying specialty occupation |
| Duration | 3 years (Canada); 1 year (Mexico); renewable indefinitely | 1 year per admission; renewable indefinitely |
| Annual Cap | No cap (Canada); 5,400/year (Mexico, rarely exhausted) | 6,800/year combined (1,400 Chile + 5,400 Singapore); rarely exhausted |
| Employer Requirement | Employer support letter; no USCIS petition for Canadians at the border | Employer files I-129 with USCIS; no lottery required |
| Spouse Work Authorization | TD dependents not work-authorized; separate EAD required | H-4 dependents not work-authorized; separate EAD required |
| Green Card Path | No dual intent; green card pursuit can jeopardize TN status | No dual intent; immigrant intent can affect renewal and admission |
| Government Filing Fees | $50 at the border. I-129 route: $780. No ACWIA or fraud fees | Consular: $205. I-129 change of status: $780. No ACWIA or fraud fees |
| Typical Legal Costs | $1,500-$4,000. Many apply at the border without an attorney | $2,000-$5,000. Less common visa; fewer specialized attorneys |
When to choose the TN visa
You're a Canadian professional who needs to start work quickly
Canadians can obtain TN status at a U.S. port of entry the same day, with no USCIS petition and no months-long wait. If you have a qualifying job offer and the right documents, you could be working within days.
Your profession appears on the USMCA list and you hold Canadian or Mexican citizenship
The TN is purpose-built for a specific list of professions. If your role qualifies, it's a cleaner, lower-cost path than the H-1B1 and avoids the USCIS petition process entirely for Canadians.
You want longer initial stays without annual renewals
Canadian TN holders are admitted for three years at a time, compared to the H-1B1's one-year increments. That means fewer renewal cycles and less administrative overhead for Canadians with stable, long-term roles.
You're a Mexican national and the H-1B cap has been exhausted
The TN cap for Mexicans (5,400 per year) is rarely hit, making it a reliable fallback when other routes are unavailable. Unlike the H-1B, there's no lottery and no unpredictable selection process.
When to choose the H-1B1 visa
You're a Chilean or Singaporean national in a specialty occupation
The H-1B1 is the only free trade visa available to Chilean and Singaporean citizens. It's structurally similar to the H-1B but without the lottery, making it a significantly more accessible path for qualifying professionals from those two countries.
Your occupation doesn't appear on the USMCA profession list
The TN is limited to specific enumerated professions. The H-1B1 uses a broader specialty occupation standard, which can cover a wider range of degree-required roles that wouldn't qualify for TN status.
Your employer prefers a USCIS-petitioned status for compliance or HR purposes
Some larger employers have established HR workflows built around USCIS-petitioned visa categories. The H-1B1's I-129 process fits that framework more cleanly than the port-of-entry approach used for Canadian TNs.
You want premium processing as an option
USCIS accepts premium processing for H-1B1 petitions, which can significantly reduce the wait time when you have a time-sensitive start date. The TN process for Canadians is already fast at the border, but Mexicans and H-1B1 applicants benefit from this option when timing is critical.

Can I switch from a TN to an H-1B1 if I change citizenship or situation?
No, the H-1B1 is only available to Chilean and Singaporean citizens, and the TN is only available to Canadian and Mexican citizens. Changing visa categories requires meeting the specific nationality requirements of the target visa, so a switch between these two types isn't possible based on a situation change alone.
Does either the TN or H-1B1 allow me to apply for a green card?
Neither visa supports dual intent, which means actively pursuing a green card can put your status at risk. Both are nonimmigrant visas that require you to maintain nonimmigrant intent. If you want to pursue permanent residence, consulting an immigration attorney before taking steps toward a green card is important while holding either status.
How does changing employers work on a TN versus an H-1B1?
On the TN, you need a new TN approval before starting with a new employer (Canadians can handle this at the border; Mexicans need a consular appointment). On the H-1B1, your new employer must file a new I-129 petition with USCIS before you begin work. Neither visa offers the portability protections that apply to H-1B holders.
Are the annual caps for TN and H-1B1 visas ever actually hit?
Rarely, if ever. The 5,400 annual cap for Mexican TN holders and the combined 6,800 cap for H-1B1 holders (split between Chile and Singapore) have not been reached in recent years. Unlike the H-1B, you don't need to worry about missing a lottery window or being selected by chance.
Can my spouse work in the U.S. if I'm on a TN or H-1B1?
Not automatically. Spouses of TN holders are admitted as TD dependents, and spouses of H-1B1 holders receive H-4 status. In both cases, the spouse needs a separate Employment Authorization Document (EAD) to work legally. The EAD is not guaranteed and requires its own application process.
