Generally, a citizen of a foreign country who wishes to enter the United States must first obtain a visa, either a nonimmigrant visa for temporary stay, or an immigrant visa for permanent residence. The North American Free Trade Agreement (NAFTA) created special economic and trade relationships for the United States, Canada, and Mexico. Select NAFTA to visit the Office of the United States Trade Representative website and learn more.
The nonimmigrant NAFTA Professional (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. Select TN NAFTA Professionals on the USCIS website to learn more about TN nonimmigrant status.
