The TN is a temporary work permit available to Canadian and Mexican citizens who will be working in the U.S. in one of the professional occupations listed in Appendix 1603.D.1 of NAFTA. This list contains over 60 occupations, including Engineer, Management Consultant, Accountant, Computer Systems Analyst and College/University Teacher. Each occupation has specific educational requirements, with most requiring a Bachelor’s degree in a related field. The TN can be approved for part-time or full-time employment.
Canadian citizens may apply for a TN through a USCIS Service Center or may apply directly at a U.S. port of entry, such as the Peace Bridge in Buffalo, NY. Port of entry cases are issued a same day decision. Mexican citizens must apply for the TN at a U.S. Consulate and must obtain a TN Visa Stamp to enter the U.S.
Canadian citizens may obtain a TN for up to 3 years at a time. Mexican citizens may obtain a TN for up to 2 years at a time. Currently, there are no limits on the number of TN extensions an individual may obtain.
