TN
The North American Free Trade Agreement (NAFTA) created special economic and trade relationships for the United States, Canada, and Mexico. The TN visa allows citizens of Canada and Mexico, as NAFTA professionals, to work in the United States in prearranged business activities for U.S. or foreign employers. Permanent residents of Canada and Mexico are not able to apply for TN visas to work as NAFTA professionals. A family member of a person who has obtained TN may reside in the United States with TD status.
