The North American Free Trade Agreement (NAFTA) made it easier for Canadian and Mexican citizens to work as professionals in the United States. Under NAFTA, qualifying professionals are given TN (Trade NAFTA) status. Canadians are classified as having TN-1 status, and Mexicans as TN-2 status. Permanent residents of Canada and Mexico do not qualify for the TN visa.
TN status is granted for an initial period of three years but may be renewed indefinitely. TN status is employer-specific. This means that if you were issued TN status based on your current job but want to switch to another job with a new employer, you must reapply for TN status based on the job offer with the new employer. Also, it is possible to have more than one TN visa at a time—this is usually the case when for example, a management consultant comes to the United States to work for a variety of employers.
Unlike the H-1B visa, there is no annual cap, or limit, on the number of TN visas available each year.
The following documentation must be provided when applying for TN status or a TN visa:
Canadian and Mexican citizens already in the United States in another status may be able to change their status to TN while remaining in the United States. Canadian citizens may also request TN status at a U.S. port of entry by providing the required documentation and paying a fee. Mexican citizens must apply for a TN visa at a U.S. embassy or consulate in Mexico.
Spouses and unmarried children under the age of 21 of Canadian and Mexican citizens in TN status are given TD status. Persons in TD status may study in the United States but are not allowed to work.
