The North America Free Trade Agreement (NAFTA) created special economic and trade relationships for the United States, Canada, and Mexico. The TN non-immigrant classification permits qualified Canadian and Mexican citizens to seek temporary entry into the United States to engage in business activities at a professional level.
To be eligible for entry to the U.S. in TN status, the TN must meet the following criteria:
Must be a citizen of Canada or Mexico
Must have a full-time or part-time job with a U.S. employer
The profession must qualify under the regulations (A list of qualifying professions can be found here: http://www.nafta-sec-alena.org/en/view.aspx?x=343&mtpiID=147#Ap1603.D.1 )
Must meet the qualifications for the profession at Emory University AND meet the educational qualifications or alternative specifications as listed on the NAFTA Approved TN Professions list.
Canadian and Mexican citizens can secure TN status for 3 year increments. As TN is regulated as a temporary employment status, TN visa holders pursuing time in TN for longer than 6 years should use caution. USCIS may deny these applications or require further proof of the “temporary nature” of the employment.
