A NAFTA job refers to employment under the North American Free Trade Agreement (NAFTA), now replaced by the United States-Mexico-Canada Agreement (USMCA). It allows certain professionals from Canada, the U.S., and Mexico to work in each other’s countries without needing a traditional work visa. These jobs fall under the TN visa category for qualified Canadian and Mexican citizens, covering professions like engineers, scientists, and accountants. Eligibility requires meeting specific education or experience criteria outlined in the agreement.
