What is a TN visa?
The North American Free Trade Agreement (NAFTA) created special economic and trade relationships for the United States, Canada and Mexico and authorized nonimmigrant NAFTA Professional (TN) visas for citizens of Canada and Mexico to work in the United States as NAFTA professionals. This visa status is available only for specific professional occupations and only to citizens of Mexico and Canada.
Obtaining an TN visa
An advantage of the TN visa is that an application can be made at the port of entry or consulate rather than with the U.S. Citizenship and Immigration Services. This can save time and money when you need to hire a worker quickly.
TN visas are issued for three years, and there is no limit to how many times the visa can be renewed.
Spouses and unmarried children under 21 accompanying a TN will be admitted under a TD status. Spouses and children will not be allowed to work but may attend school full-time while in a TD status.
