For most Canadian and Mexican professionals whose job is on the USMCA list, the TN is the faster and simpler choice: no annual cap, no lottery, no labor condition application, and an application that can be decided in a single day at the border. The H-1B wins in two situations: when the job is not on the TN list, and when the employee plans to apply for a green card soon. Choosing between TN and H-1B is less about which visa is better and more about where the employee wants to be in three to five years. Our TN professional visa team often plans both, in sequence.

Eligibility: a fixed list versus a broad standard

The TN covers only the professions on the USMCA list, each with its own degree or license requirement. Our list of TN visa professions shows them all. Some common roles, such as software developer or programmer, marketing manager and financial analyst, do not appear on it or fit only under a related category with careful drafting.

The H-1B covers any specialty occupation, meaning a job that normally requires at least a bachelor’s degree in a specific specialty. That standard is broader, so roles that do not fit a TN category often fit an H-1B. If the job clearly matches a TN profession, though, the narrower list is not a disadvantage.

Speed, cap and timing

The H-1B is subject to an annual cap for most private employers. The employer registers in the spring lottery, a selected registration allows a petition to be filed, and the employee can usually start no earlier than October 1. If the registration is not selected, the employer waits a full year to try again, unless it is a cap-exempt employer, such as a university or certain nonprofit research organizations.

The TN has no cap. A Canadian can apply at a port of entry once the offer is signed; a Mexican citizen needs a consular interview first. Our guide to the TN application process for Canadians and Mexicans walks through both routes. For an employer that needs someone to start next month, this difference usually decides the question.

Employer obligations and cost

An H-1B employer must file a labor condition application with the Department of Labor, pay at least the prevailing or actual wage, keep a public access file and pay several filing fees, some of which depend on company size. The TN has no labor condition application and no prevailing wage filing, and the government fees are lower. Employers should still pay a wage consistent with a professional role, because a low salary invites questions about whether the job is truly professional.

Check the current USCIS and CBP fee schedules before budgeting either route, since fees change.

Time limits, job changes and family

TN status is granted for up to three years at a time and can be renewed without a fixed lifetime limit, as long as the stay remains temporary. H-1B status is generally limited to six years, with extensions beyond six years available when a green card case has reached certain stages.

Job changes work differently. An H-1B worker can usually start with a new H-1B employer as soon as the new petition is filed. A TN worker needs a new approval, from USCIS or at the border or consulate, before starting the new job. Plan these changes so there is no gap in work authorization.

For spouses, neither status is generous. TD spouses cannot work. H-4 spouses can work only with an H-4 work permit, which is available in limited cases, mainly when the H-1B worker has an approved I-140 or an extension based on a pending green card case.

Dual intent and the green card question

This is the biggest difference. The H-1B is a dual intent status: the employee can pursue a green card while holding it without undermining the visa. The TN is not. A TN holder must intend a temporary stay, and an officer who sees a pending green card case may question that intent at the next border crossing or renewal.

TN holders do get green cards, and our post on TN visa green card options explains the strategies. Many employers use a hybrid plan: start the employee on a TN for speed, register for the H-1B lottery in the meantime, and move to H-1B before the green card case reaches the stages most likely to cause trouble at the border. CLP’s H-1B visa practice runs that switch as part of the overall plan, including the lottery registration and the change of status petition.

TN or H-1B: a short decision guide

Choose the TN when the job is clearly on the list, the employee needs to start soon, and there is no near-term green card plan. Choose the H-1B, or a TN-then-H-1B sequence, when the job is not on the list, the employee wants a green card within a few years, or the spouse’s ability to work is a priority and the green card case will soon qualify the spouse for an H-4 work permit.
