The TN Category for Canadian and Mexican Citizens

The TN category was established as part of the North American Free Trade Agreement (NAFTA). Citizens of Canada or Mexico coming to the U.S. on a temporary basis for professional employment with a specific employer may use this immigration option.

Canadian and Mexican faculty members, research fellows, and other post-doctoral researchers may now choose among J-1, H-1B and TN visa statuses, with the advice and assistance of the ISSO. The TN status is similar to the H-1B except that it is also available to non-academic professionals at Columbia, e.g., computer programmers, technicians, and research assistants. A baccalaureate degree is the minimum requirement to qualify for TN status in certain professions.

This nonimmigrant visa category will allow a Mexican or Canadian citizen (but not a Canadian landed immigrant) to enter the U.S. temporarily to engage in activities at the professional level. These activities have been defined as employment which requires at least a bachelor's degree or appropriate credentials demonstrating status as professional and are on the list of allowable professions as defined by the Treaty at http://travel.state.gov/visa/temp/types/types_1274.html.

To enter the U.S. in TN status, a Canadian citizen should make an application at a port of entry to the United States. Canadians do not apply for a visa. Mexican citizens make an application at a United States Consulate for a TN visa.

When entering the U.S., a Canadian citizen must present the following documents:
