TN vs H-1B: Which Is Better for Canadians and Mexicans?

TN status comes from the United States-Mexico-Canada Agreement (USMCA). You need a job offer from a US employer (or a contract with a US client) in a listed profession, and the job must actually be at a professional level in that profession.

• Canadians usually apply at a US port of entry or preclearance station with a job letter, proof of qualifications, and proof of citizenship. No visa is needed.
• Mexicans first apply for a TN visa at a US consulate, then present it at the border.
• Employers can also file Form I-129 with USCIS, which costs $1,015 on paper or $965 online ($510 for small employers), plus the Asylum Program Fee, as of September 2026.

The July 2026 USMCA joint review did not change TN rules. Employers can read our TN guide for employers.

The H-1B needs an employer to register you in the spring lottery, unless the employer is cap-exempt (for example a university). Since 2026, the lottery gives more entries to higher wage levels. If selected, the employer files a Labor Condition Application and Form I-129, and you can usually start on October 1.

Employer costs include a $215 registration fee, the I-129 fee, the ACWIA training fee, a $500 fraud fee for initial petitions, and the Asylum Program Fee. The $100,000 payment from a 2025 proclamation is not being collected after a June 8, 2026 court ruling; see the H-1B fee status page. Read how the H-1B lottery works.

• Job title vs real duties. Border officers look at what you will actually do. A "management consultant" letter for a job that is really general management, or an "engineer" title for a non-engineering role, is a common reason for refusal.
• Wrong credentials. Each USMCA profession has a set requirement, usually a specific degree and sometimes a license. Bring originals and transcripts.
• Unclear end date. Your letter should describe a temporary assignment with a set period.
• Canadian permanent residents who are not Canadian citizens cannot use TN.
• Self-employment. You cannot use TN to work for your own US company.

A refusal at the border is recorded, so prepare carefully or have a lawyer review your letter first.

For TN, very little: the July 2026 USMCA joint review left TN rules unchanged and moved the agreement to annual reviews. For the H-1B, a lot: the wage-weighted lottery, the court fight over the $100,000 payment, and premium processing rising to $2,965 on March 1, 2026. Both are blocked for nationals of the 19 countries under a full travel ban, which does not include Canada or Mexico. Check USA Status Now before you apply.

This is often what decides the choice.

• TN requires temporary intent. Filing a green card petition does not automatically end TN status, but it can make a TN renewal or border entry harder, because the officer may decide you intend to stay permanently. Timing matters, especially for Mexicans who need a new TN visa.
• H-1B allows dual intent. You can have a PERM, I-140, or I-485 pending and still extend, travel, and renew.

For this reason, many TN professionals switch to H-1B (or L-1) before starting a green card, or use a strategy their lawyer plans around trips and renewals. In 2026, a USCIS memo limits adjustment of status for people on temporary visas, which makes timing even more important. Talk to a licensed immigration lawyer before filing. See US green card options.

Choose TN if you:

• are a Canadian or Mexican citizen and your job is clearly on the USMCA list
• want to start quickly, without waiting for the lottery
• do not plan to pursue a green card soon
• are Canadian and want the simple port-of-entry process

Choose H-1B if you:

• are not a Canadian or Mexican citizen
• work in a job that is not on the USMCA list, such as many management or general business roles
• plan to pursue a green card soon and want dual intent
• want your spouse to have a chance at work authorization through the H-4 EAD

Canadians and Mexicans who qualify for both often start on TN and move to H-1B when they begin a green card process. See also H-1B vs O-1 and working in the USA.
