An Overview of the TN

The TN is one of the simplest ways for Canadian and Mexican professionals to work in the United States, granting temporary visas to serve in qualifying professions. There’s no annual cap or lottery, and Canadians often need neither a visa nor a USCIS petition.

However, that simplicity comes with trade-offs. The TN is a temporary, three-year visa. Though it can be renewed indefinitely, it’s tied to a specific employer and profession, and it depends on a trade agreement whose future is under review.

Who Is Eligible for the TN?

Four requirements apply. The applicant must:

  • Be a citizen, not just a permanent resident, of Canada or Mexico

  • Work in a profession on the United States-Mexico-Canada Agreement (USMCA) list, which includes fields such as engineering, accounting, science, management consulting, and computer systems analysis

  • Meet the education or credential requirements for that profession, usually a bachelor’s degree or applicable professional license

  • Have a job offer that fits the criteria from a U.S. employer

Self-employment does not qualify, and the job duties must genuinely match the listed profession. The applicant must also intend to stay only temporarily.

The Application Options, Explained

  • Canadian Citizens

    Canadians do not need a visa. They can apply directly at a port of entry or airport preclearance station with their documents, or the employer can file a Form I-129 with USCIS.

  • Mexican Citizens

    Mexicans must first apply for a TN visa at a U.S. consulate, then present their documents at the border for admission.

  • Changing or Extending Status

    Applicants already in the U.S. can have their employer file a Form I-129 to extend or change their legal status to a TN visa.

What Are the Advantages of the TN?

  • No Cap, No Lottery

    TN professionals do not compete for limited numbers, so an eligible applicant can start as soon as a job offer is in place.

  • Speed and Simplicity

    Canadians can often be approved on the spot at the border. There’s no labor certification, and the paperwork is lighter than for most work visas.

  • Renewable Status

    TN status can be extended in three-year increments with no fixed overall limit, as long as the job remains temporary in nature.

  • Room for Family

    Spouses and unmarried children under 21 may enter the U.S. in TD status. They can study, but they can’t work.

A Note on the USMCA

Because the current TN framework comes from the USMCA, the agreement’s future matters. Its first six-year review took place in July 2026 without the parties agreeing to extend the agreement for a new 16-year term. The USMCA remains in force, with annual reviews now required until the parties agree to an extension or the current term expires. No changes to TN eligibility or procedures have been announced, but applicants and employers should follow developments and consider longer-term immigration options if they plan to remain in the U.S.

How to Apply

Preparation is mostly about documents. Start with:

  • Passport(s)

  • Proof of Canadian or Mexican citizenship

  • Latest I-94 arrival record, if already in the U.S.

  • Any previous or current U.S. visa stamps and their corresponding approval notices

  • Proof of education, such as diplomas and transcripts, with a credential evaluation if needed

  • Copies of professional licenses, if applicable

  • A comprehensive resume or CV

The employer should provide a letter that covers:

  • The job title and a detailed description of the duties, showing they fit the listed profession

  • The purpose and length of the employment

  • The salary and any other compensation

  • The applicant’s qualifications for the role

The application also requires:

  • Form I-129, if filing with USCIS

  • The visa application and interview for Mexican citizens

  • All applicable fees

Common Pitfalls to Avoid

  • Duties That Do Not Fit the Profession

    The job has to match a listed profession in substance, not just in title. Officers look at what the applicant will actually do.

  • Self-Employment

    TN status requires a U.S. employer. Self-employed professionals generally don’t qualify.

  • Missing Paperwork at the Border

    At a port of entry, an officer decides on the spot. A missing document or an unclear employer letter can lead to a denial, and there’s no advance approval to fall back on.

  • Immigrant Intent

    The TN does not allow dual intent, meaning applicants must show they plan to leave when the status ends. A pending green card case can complicate admission, so anyone with permanent residence plans should get professional legal advice first.

Is the TN a Good Fit?

The TN suits Canadian and Mexican professionals with a qualifying job offer who want to start working in the U.S. quickly. If your profession is on the list and you plan to work here for a defined period, the TN may be the right choice.
