TN
TN USMCA Professionals
A Fast, Flexible Path for Canadian and Mexican Professionals to Work in the United States
Overview
The TN classification allows qualified Canadian and Mexican citizens to work temporarily in the United States in designated professional occupations under the USMCA. Applicants must have a prearranged professional position, meet the specific education or experience requirements for the selected occupation, and present documentation showing that the offered role fits the applicable TN category. Canadian citizens may generally apply for TN status at a U.S. port of entry, while Mexican citizens must first obtain a TN visa through a U.S. embassy or consulate.
Who qualifies
- 01Citizens of Canada or Mexico (citizenship, not permanent residence) who hold a prearranged offer from a U.S. employer to work in a qualifying professional occupation.
- 02Professionals whose occupation appears on the USMCA (formerly NAFTA) list — including engineers, scientists, accountants, architects, lawyers, economists, management consultants, and a range of healthcare and scientific roles.
- 03Applicants who hold exactly the credential the occupation requires — typically a relevant bachelor's degree, or, for certain occupations, the applicable license or a defined combination of education and experience.
- 04Candidates entering to perform duties at a genuinely professional level for a U.S. or foreign employer; TN does not permit self-employment or work for a business in which the applicant holds a controlling interest.
- 05Spouses and unmarried children under 21, who may accompany the principal in TD dependent status and study in the U.S., though TD status does not authorize employment.
Process
- 01
Confirm the occupation qualifies
The threshold question is whether the offered role maps to a specific profession on the USMCA list and whether the candidate holds exactly the credential that profession requires. A role that is professional in spirit but does not fit a listed occupation — or a candidate whose degree is in an unrelated field — is the most common reason a TN is refused at the border.
- 02
Prepare the employer support letter
TN cases stand or fall on the support letter. It must identify the specific TN profession, describe duties that are genuinely at a professional level, state that the position is temporary, specify the duration requested, and connect the candidate's credentials to the role. Vague or boilerplate duty descriptions invite scrutiny.
- 03
Assemble credential evidence
Degrees, transcripts, licenses, and — where the occupation permits experience in lieu of a degree — detailed evidence of qualifying experience. Foreign credentials are accompanied by an equivalency evaluation where the occupation's U.S. standard calls for one.
- 04
File by the correct route
Canadian citizens generally apply for TN admission directly at a U.S. port of entry or preclearance, or through an I-129 petition filed with USCIS. Mexican citizens must first obtain a TN visa at a U.S. consulate before seeking admission. The route determines timing, documentation, and where the case is adjudicated.
- 05
Maintain and renew
TN status is granted for up to three years and can be renewed indefinitely in further increments, either at a port of entry or by an I-129 extension. Because TN is a nonimmigrant category, each renewal is an occasion to confirm the role still qualifies and to manage any immigrant-intent considerations if a green card is being contemplated.
Frequently asked
How long can I stay in the United States on TN status?
TN admission is granted for up to three years at a time. There is no overall cap on the number of renewals, so a professional can remain in TN status for many years — provided the position remains temporary in nature and the candidate continues to meet the requirements of the listed occupation at each renewal.
Can my spouse and children come with me?
Yes. A spouse and unmarried children under 21 may accompany you in TD dependent status. They may live and study in the United States, but TD status does not authorize employment. A dependent who wishes to work would need to qualify for a work-authorized status in their own right.
Can I work for more than one employer on a TN?
Yes — you may hold concurrent TN status for more than one qualifying employer, with separate support documentation for each position. What TN does not permit is self-employment or working for a business in which you hold a controlling interest; the classification is built around employment by an arm's-length employer.
Can I apply for a green card while on a TN?
TN is a nonimmigrant classification that does not carry 'dual intent,' so an unguarded pursuit of permanent residence can create problems at renewal or re-entry, where an officer may view fixed immigrant intent as inconsistent with TN status. Moving from TN toward a green card is possible, but the timing and sequencing need to be managed deliberately — this is a point where advice before you act matters.
How does applying differ for Canadian and Mexican citizens?
Canadian citizens generally do not need a visa: they can request TN admission directly at a U.S. port of entry or preclearance with their support documents, or their employer can file an I-129 petition. Mexican citizens must first apply for a TN visa at a U.S. embassy or consulate, attend an interview, and then seek admission. The practical effect is a difference in processing time and in where the case is first decided.
