Who qualifies as a TN?
The United States Mexico Canada Agreement (formerly North American Free Trade Agreement (NAFTA)) created special economic and trade relationships for the United States, Canada and Mexico. The TN nonimmigrant classification permits qualified Canadian and Mexican citizens to seek temporary entry into the United States to engage in business activities at a professional level.
TN classification does require an employer to “sponsor” an individual for TN work status. Employers must request employment authorization on behalf of a TN worker either from USCIS (if worker is or will be inside the US), or Customs and Border Protection (CBP) upon entry into the US (if worker is or will be outside the US).
