NAFTA Professional (TN) visa allows citizens of Canada and Mexico whose profession is on the NAFTA list and who must hold a bachelor's degree to work in the United States on a prearranged job. Canadian citizens usually do not need a visa to work under the TN status (unless they live outside Canada with non-Canadian family members) while Mexican citizens require a TN visa. Spouse and dependent children of a TN professional can be admitted into the United States in the TD status.
