The TN visa category, created under the North American Free Trade Agreement (NAFTA), now the USMCA, allows Canadian and Mexican professionals to work temporarily in the United States. Understanding the specific educational and professional criteria, especially in scientific and medical fields, is crucial for successful visa applications. This blog explains these requirements, providing clarity and guidance for TN visa applicants.
Educational Criteria for Scientific Technicians/Technologists
Applicants must demonstrate that they hold theoretical knowledge and practical problem-solving skills to qualify as scientific technicians or technologists under the TN visa category. Applicants are also required to have at least two years of post-secondary education or training in a relevant field. This education must be directly related to the job offer in the U.S., ensuring that the applicant possesses the necessary skills and knowledge for the position. Additionally, the applicant must be directly supporting a supervisory professional whose duties fall within specified fields, and the applicant’s primary activities must align with a Scientific Technologist, as demonstrated by the nature of the work, and documented by training and experience.
Requirements for Medical Laboratory Technologists
Medical laboratory technologists play a vital role in healthcare, conducting essential tests and analyses. An applicant in this category must be seeking temporary entry to perform in a laboratory chemical, biological, hematological, immunologic, microscopic, or bacteriological tests and analyses for diagnosis, treatment, or prevention of diseases. For TN visa eligibility, these professionals must hold specific qualifications, often a bachelor’s degree in medical technology or a related field, and three years experience. Additionally, they must meet certification standards as required in the U.S. and obtain a VisaScreen no matter where they were educated.
Guidelines for Physicians (Teaching or Research Only)
Physicians interested in the TN visa must understand that this category is limited to those focusing on teaching or research roles and does not include direct patient care. However, patient care incidental to teaching or research is permissible Applicants must possess a medical degree and should understand the balance between teaching/research responsibilities and limited patient care activities.
Registered Nurses: Licensing and Certification

Applicants can seek temporary or permanent licenses, depending on their long-term career goals and the nature of their U.S. engagement. Nurses are also required to obtain a VisaScreen.
