TN status (or TN classification; "TN" from Trade NAFTA) is a special non-immigrant classification of foreign nationals in the United States, which offers expedited work authorization to a citizen of Canada or a national of Mexico. It was created as a result of provisions of the North American Free Trade Agreement that mandated simplified entry and employment permission for certain professionals from each of the three NAFTA member states in the other member states. The provisions of NAFTA relevant to TN status were then carried over almost verbatim to the United States–Mexico–Canada Agreement that replaced NAFTA in 2020.
A Canadian citizen or Mexican national with a job offer from a U.S. employer in certain defined professions and who meets the minimal education requirements for the relevant profession can work in the United States, for up to three years. The classification theoretically may be renewed indefinitely, although real-world complications may limit the number of times, or overall length of time, a foreign national might successfully be granted an authorized period of admission into the United States in the classification.
For Mexican nationals, being granted admission in TN classification generally requires first being issued a TN visa at a U.S. consular post. In contrast, Canadian citizens, who are generally exempt from the usual requirement of U.S. federal regulations to obtain a U.S. visa in advance of requesting admission to the U.S. (with limited exceptions), generally simply present their relevant paperwork directly to a U.S. Customs and Border Protection officer when seeking a new period of authorized admission into the United States in TN status. For both Mexican nationals and Canadian citizens already present in the United States and maintaining lawful immigration status in a classification other than TN, TN classification can also be granted through a "Change of Status" process initiated by a U.S. employer's petition for TN status on behalf of that prospective or current employee.
Canada's corresponding NAFTA work permit for U.S. citizens and Mexican nationals is sometimes unofficially also referred to as a TN status or TN visa, although this name is technically only a creation of U.S. law.
TN classification bears a similarity, in some ways, to the U.S. H-1B classification, but also has unique features. Notably, H-1B classification allows for "dual intent" to obtain Lawful Permanent Resident (LPR) status in the United States, while TN status does not. This leads to a variety of practical considerations for a TN status holder offered a transition to U.S. permanent residence by an employer or U.S. citizen or LPR spouse.
History
NAFTA negotiation and ratification
The governments of Canada, Mexico, and the United States negotiated a regional free trade agreement, which came to be known as NAFTA, during the 1980s. The leaders of the three nations signed the agreement in their respective capitals on December 17, 1992.
NAFTA included an Appendix 1603.D.1 that required each of the member-states to institute laws and regulations for the free temporary movement of certain professionals among the three member-states with special simplified immigration procedures.
United States federal law
NAFTA was implemented in U.S. federal law in 1993 through the North American Free Trade Agreement Implementation Act, H.R. 3450, Pub. L. 103-182, 107 Stat. 2057.
After approval of the measure by the U.S. House and U.S. Senate, President Bill Clinton signed the law on December 8, 1993, placing NAFTA into effect on January 1, 1994.
The measure inserted a new sub-paragraph into section 214 of the Immigration and Nationality Act, codified at United States Code, title 8, section 1184, that states:
In 2020, this wording was updated by the United States-Mexico-Canada Agreement Implementation Act to reflect the new agreement.
United States federal regulations
The regulations described in the NAFTA Implementation Act were promulgated on December 30, 1993, in a regulation entitled "Temporary Entry of Business Persons Under the North American Free Trade Agreement (NAFTA)".
It amended section 214.6 of the Code of Federal Regulations, title 8, to provide procedures for "Canadian and Mexican citizens seeking temporary entry to engage in business activities at a professional level".
The section states that "Pursuant to the NAFTA, an applicant seeking admission under this section shall demonstrate business activity at a professional level in one of the professions set forth in Appendix 1603.D.1 to Annex 1603" and then sets forth the professions agreed upon by the NAFTA member states.
