This nonimmigrant visa category allows Canadian citizens (but not landed immigrants) to enter the United States to engage in professional activities. These activities are undertakings that require at least a baccalaureate (bachelor's) degree or appropriate credentials demonstrating status as a professional.
Dependents of a person holding TN status can enter on TD status, but are not allowed to work.
Canadian citizens apply at the U.S. border by presenting their offer letter from Cornell. A Canadian citizen entering in this category can apply to stay for up to three years at a time, renewable indefinitely. There is no limit to the number of possible extensions.
Extension of TN status within the US: While most TN's are renewed in-person at a U.S. border crossing, current travel conditions are resulting in inquiries about extensions of status within the U.S. For more information about this process and Cornell sponsorship policies, please contact us.
Mexican citizens also qualify for the TN visa, but application procedures are more complicated. Email us for details.
For Canadians: How to Apply for TN
- Get Letter
- Apply
1 Get a TN support letter.
The hiring department provides TN support letter that is addressed to U.S. Customs and Border Protection and lists the salary, complete description of job duties, length of stay, and requirements for degree or licenses. The job title must mirror one on the list of accepted professional occupations. See the list of accepted professional occupations.
Sample TN Hiring Department Letters
The letter from the department or hiring unit must include a professional title that clearly relates to one of the occupations on the TN list of professional occupations. See the list of accepted professional occupations per the USMCA treaty (formerly NAFTA).
For this reason, a Cornell academic title alone (for example, research associate II) may not be sufficient. If the academic title is not descriptive, be sure to include a working title in the letter, as well as a full description of the nature of the job duties, the anticipated length of stay, and the pay arrangements.
The letter on official letterhead must also include the following data elements:
- Be on official letterhead
- Be dated
- Be addressed to U.S. Customs & Border Protection
- Include a detailed job description
- Include salary and benefits
- Include duration of employment (up to two years)
- Be originally signed by the hiring authority
