For a Mexican engineer, accountant or nurse with a U.S. job offer, the first decision is often which visa to use. The TN and the H-1B can both cover professional jobs, but they work very differently: one is fast, uncapped and tied to a list of professions, and the other is capped, more expensive and far better for a long-term green card plan. Choosing well at the start can save a year of uncertainty later.

TN vs. H-1B: The Short Answer
Quick answer: Choose the TN when your job matches one of the USMCA professions and you want to start working quickly, because the TN has no annual cap or lottery and can be renewed in three-year periods. Choose the H-1B when you plan to pursue a green card, your job is not on the TN list, or you want more flexibility, because the H-1B allows dual intent and can be extended past six years while a green card is pending. Many professionals start on a TN and move to H-1B later.
Side-by-Side Comparison
| TN | H-1B | |
|---|---|---|
| Who qualifies | Mexican and Canadian citizens in a listed USMCA profession | Any nationality in a specialty occupation requiring a related bachelor’s degree |
| Annual cap | None | 85,000 new visas a year for most employers, selected by registration |
| How Mexican citizens apply | Visa interview at a U.S. consulate | USCIS petition, then a visa interview at a consulate if abroad |
| Length | Up to 3 years at a time, renewable without a set limit | Up to 3 years at a time, 6 years total, with extensions while a green card is pending |
| Green card intent | Not allowed (single intent) | Allowed (dual intent) |
| Spouse work | TD spouses cannot work | H-4 spouses can work in some cases |
| Wage rules | No set prevailing wage filing | Labor condition application and prevailing wage required |
When the TN Is the Better Choice
The TN is often the fastest way for a Mexican professional to start working in the United States. There is no lottery, so a qualified professional with a job offer can apply at any time of year. Mexican citizens apply for the TN visa at a U.S. consulate, and since the State Department narrowed interview waivers in 2025, most applicants should expect an in-person interview. Since October 1, 2026, TN and TD visa applicants have also been included in the State Department’s review of applicants’ online presence, which asks them to make their social media profiles public.
The TN fits best when the job clearly matches a profession on the USMCA list, such as engineer, accountant, computer systems analyst, management consultant or registered nurse, and when you are not yet planning to apply for a green card. You can see the full list in our guide to TN visa requirements and professions.
When the H-1B Is the Better Choice
The H-1B is the stronger choice for professionals who plan to stay. Because it allows dual intent, your employer can sponsor you for a green card without risking your status, and you can usually extend the H-1B past six years while the green card case moves forward. The H-1B also covers specialty occupations that are not on the TN list.
The challenge is getting in. Most new H-1B workers need to be selected in the annual registration, which since 2026 has been weighted toward higher wage levels. Universities, affiliated nonprofits and certain research organizations are exempt from the cap, so professionals hired by those employers can file at any time. The registration for the next cap season is expected in March 2027. Our guide to the weighted H-1B selection system explains how the odds work.
Costs and Fees in 2026
The H-1B costs more. Employers pay USCIS filing fees, a fraud prevention fee and, for most employers, an additional training fee, and employers with 50 or more U.S. employees and more than half of them in H-1B or L-1 status pay an extra $4,000 on initial petitions and, since September 9, 2026, on extensions. A $100,000 fee imposed in 2025 on certain new H-1B petitions for workers outside the United States was vacated by a federal court in June 2026, and in July 2026 an appeals court declined to reinstate it while the appeal continues. Employers should still confirm its status before filing a new petition for someone abroad.
The TN is simpler and cheaper for Mexican citizens: the consular visa fee, the employer’s support letter and the documents proving the professional qualification.
The USMCA Question
The TN exists because of the United States-Mexico-Canada Agreement. At the agreement’s first joint review on July 1, 2026, the United States declined to renew it in its current form, but the agreement remains in force and the TN rules did not change. Absent an extension, USMCA would end on July 1, 2036, with annual reviews until then. For now, the TN remains fully available, but professionals who plan to stay long term have one more reason to consider an H-1B or a green card plan. Read our update on the USMCA review and TN visas.
Two Examples
Consider a civil engineer from Saltillo with an engineering licenciatura and an offer from a San Antonio construction firm. The job matches the engineer profession, she wants to start within weeks and she is not sure she will stay long term. The TN is the natural fit.
Now consider a software developer from Monterrey with a computer science degree, an offer from a San Antonio company and a goal of raising his family in Texas. A programming job does not fit the TN professions as USCIS now reads them, and he wants a green card. The H-1B, or a cap-exempt employer if one is available, is the better plan even though it takes longer to start.
Switching From TN to H-1B
Many of our clients start on a TN, then switch to H-1B before beginning a green card case. The switch requires a registration selection unless the employer is cap exempt, and the timing should line up with the TN expiration and any planned travel. Once in H-1B status, the green card process can proceed without the intent problems the TN creates. Our guide to going from TN visa to green card covers the alternatives.
Mistakes Mexican Professionals Make
- Using a job title that does not match the TN profession. The duties, not the title, decide the case, and the 2025 USCIS guidance narrowed several professions.
- Assuming the TN leads to a green card. It can, but only with careful timing.
- Missing the H-1B registration window when a green card is the long-term goal.
- Forgetting about the family. TD spouses cannot work, which can tip the decision toward H-1B.
- Inconsistent online profiles. With the online presence review, a résumé or profile that does not match the application can raise questions.

Frequently Asked Questions
Is the TN or the H-1B better for Mexican professionals?
The TN is usually faster and cheaper if the job matches a USMCA profession. The H-1B is usually better if you plan to apply for a green card or your job is not on the TN list.
Can I switch from TN to H-1B?
Yes. Your employer needs a registration selection unless it is cap exempt, then files an H-1B petition. Many professionals switch before starting a green card case.
Does the TN have a time limit?
There is no set limit on TN renewals, but each stay is temporary, and you must keep showing that you intend to leave when your TN status ends.
Can my spouse work on a TD or H-4?
TD spouses cannot work. H-4 spouses can apply for a work permit in certain situations, such as when the H-1B worker has an approved I-140.
Does the $100,000 H-1B fee apply to TN workers?
No. The fee applied only to certain new H-1B petitions and has been vacated by a federal court while the appeal continues.
Will the USMCA review end the TN visa?
Not now. The United States declined to renew USMCA in its current form in July 2026, but the agreement remains in force and TN rules have not changed.
