The North American Free Trade Agreement (NAFTA) creates special economic and trade relationships for the United States, Canada and Mexico. The TN nonimmigrant status allows professionals from Canada and Mexico to work in the United States. Mexican professionals must obtain a TN visa at a U.S. consulate or embassy to enter the United States. Canadian professionals can request TN status at a U.S. port of entry.
When completing Section 1 of Form I-9, an employee in TN status should check “An alien authorized to work” and write the Admission number and expiration date of his or her status from Form I-94/I-94A. The employee’s unexpired Form I-94 together with his or her unexpired foreign passport are acceptable as a List A document for Form I-9.
In the alternative, employees in TN status may present a List B document with a List C document. A Form I-94/I-94A indicating admission in TN status would be acceptable. In this case, as a List C#8 document.
To complete Section 2 (or Section 3 if reverifying) of Form I-9, employers should follow the applicable instructions.
