TN status allows citizens of Canada and Mexico, considered NAFTA professionals, to work in the United States. TN status is available only for professions listed on the NAFTA Professions List.
What is the TN Visa?
Under the North American Free Trade Agreement (NAFTA), Canadian and Mexican citizens may enter the United States in TN status to engage in certain professional business activities. Only certain occupations may serve as the basis for receiving TN status to work in the United States.
Canadian and Mexican citizens may enter the US in TN status for up to 3 years. Upon completion of the initial time in TN status, an extension of stay may be requested for up to 3 years. Unlike J status and H status, TN status does not have a cumulative total time limit, and may be renewed indefinitely as long as the nature of the stay remains temporary.
Canadian citizens will apply for TN status at a U.S. port of entry. They do not need to apply for, or obtain, a TN visa before being admitted into the U.S. in TN status.
Mexican citizens will apply for, and must obtain, a TN visa at a U.S. consulate before being admitted into the U.S. in TN status.
8 CFR 214.6 contains the federal regulations that govern TN status.
