TN Visa Guide: Work in the US (Canada & Mexico)

If you are a citizen of Canada or Mexico and have received a job offer in the US, the TN visa is almost certainly the first thing you should look into. It is one of the few ways to start working in the US quickly, without the months-long wait for the visa lottery or the complex sponsorship process typical of most other categories.

‍

The TN visa exists thanks to the USMCA (formerly NAFTA) trade agreement between the US, Canada, and Mexico. And it is this agreement that determines who can use it and under what conditions.

‍

If you’ve been wondering what a TN visa is, whether it’s right for you, and how the application process works, we’ve prepared this guide and a short TN visa documents checklist for you. Read on to learn a lot of useful information that is truly important in practice.

‍

What Is a TN Visa?

In short: what is a TN visa? It is a non-immigrant work visa category available exclusively to citizens of Canada and Mexico under the USMCA agreement. TN status allows you to work in the US temporarily in one of the predefined professions listed in the agreement itself.

‍

The list of professions is quite broad and includes: engineers, accountants, scientists, pharmacists, IT professionals (in certain categories), architects, lawyers (with restrictions), college and university professors, as well as several other specializations, but specifically “several other” rather than “any profession.” If your role is not on the list, the TN visa will not be suitable, even if you have an excellent job offer.

‍

Key requirement: Only citizens of Canada and Mexico can apply for TN status. If you are a citizen of another country but have resided in Canada or Mexico, you will still need to consider other visa categories, such as the H-1B visa.

‍

TN Visa for Canadian Citizens

One of the main advantages of the TN visa for Canadian citizens is its incredibly simple process compared to virtually all other US work visas.

‍

Canadians do not need to file a petition in advance or wait for consular approval. The process takes place right at the border: a Canadian citizen arrives at a port of entry (this can be an airport or a land crossing), presents the necessary documents to a Customs and Border Protection (CBP) officer, and, upon approval, receives TN visa status practically on the spot, in a single visit.

‍

For Mexican citizens, the process works differently: they must apply in advance through the US consulate and obtain a visa before crossing the border. In other words, Mexicans face an additional consular step that Canadians simply do not have.

‍

The difference is that a Canadian can theoretically receive a job offer on Monday and be at the border as early as Wednesday. A Mexican, however, will have to wait for consular approval.

‍

Does the TN Visa Require Sponsorship?

A common question: Does the TN visa require sponsorship? Formally, no, but not “not at all.”

‍

The TN visa does not require an I-129 petition or USCIS approval, as the H-1B does. However, without a job offer from an employer in the US, a TN visa will not be issued. In other words, the very existence of the status is tied to a specific position with a specific employer.

‍

What is required from the employer in practice: An official offer letter describing the position, duties, and qualifications, and confirming that the position falls under one of the USMCA categories. This is not “sponsorship” in the legal sense of the H-1B, but without this letter, it is impossible to obtain a visa.

‍

Thus, the process is much faster and cheaper than the H-1B, but it requires that you have a concrete job offer in hand.

TN Visa Documents Checklist

To avoid being denied at the border (yes, this happens, and the most common reason is an incomplete set of documents), it’s worth preparing a complete TN visa documents checklist in advance.

‍

The basic set includes:

• Proof of Canadian or Mexican citizenship (passport).
• A job offer letter from a US employer with a detailed description of the position and salary.
• Documents confirming your qualifications (diploma, certificates, licenses, depending on your profession).
• A resume demonstrating relevant experience.

‍

A few practical tips to avoid common rejections: Make sure the job description in the employer’s letter matches the wording in the USMCA list of professions exactly - discrepancies in terminology often lead to questions at the border. Bring the original copies of your educational documents, not just copies. And be prepared for brief questions from the CBP officer about your role, salary, and duration - calm and specific answers significantly simplify the process.

TN to Green Card: Is It Possible?

The transition from TN to a Green Card is a complex topic due to many legal nuances.

‍

The main challenge is called “dual intent.” A TN visa is, by its nature, non-immigrant: when you apply, you are effectively declaring your intention to return home after completing your work. A green card, on the other hand, implies an intention to stay permanently. These two intentions formally contradict each other, which is precisely why the process requires careful handling.

‍

In practice, real-life cases show that this is indeed possible. Many TN status holders successfully obtain permanent residency through their employer, typically under the EB-2 or EB-3 categories (employer-sponsored permanent residency).

‍

The main risk is renewing the TN visa after the green card process has already begun. If a border officer has doubts that your intention remains “temporary,” the renewal may be called into question. Therefore, the transition from TN to a green card should almost always be planned with an immigration lawyer who can synchronize both processes.

‍

Renewing & Maintaining TN Status

The TN visa is initially issued for up to three years, and one of the best pieces of news is that TN status can be renewed an unlimited number of times (unlike many other types of visas).

‍

The condition for renewal is simple but important: you must continue to work in the same or a comparable position within the original USMCA category. Changing employers isn’t necessarily a problem, but it requires a new process: a new job offer letter, and in most cases, a new border crossing to process your status under the new employer.

‍

Practical tips: keep copies of all job offer letters and status confirmations - you’ll need them for every renewal. If you plan to travel outside the US and back, make sure your status is valid upon your return. And when changing jobs, do not start your new position until you have obtained new TN status under the new employer, even if it seems like “the difference is minor.”

‍

Navigating visa issues is only part of the move. If, in addition to a visa, you need help with housing, schools for your children, or a full settling-in package, the Expat US team handles the entire process, from the first job offer letter until you’re settled in your new home.
