How Mann Law Group helps
The TN category lets citizens of Canada and Mexico work in the United States in listed professional occupations for a U.S. or foreign employer. It is fast when the job fits the list and the documents are right, and it fails at the border when they are not. Mann Law Group helps employers and professionals match the job to a listed occupation, prepare the support letter, and plan renewals and the long-term route.
Common services and issues
What to keep in mind
- In July 2026 the United States did not agree to extend the USMCA for a new term. The agreement and the TN category stay in force, and TN rules have not changed, but the future of the agreement is uncertain. Watch for updates.
- The job title does not decide the case. The actual duties must match a listed profession, and officers look closely at roles such as engineer, scientific technician, and management consultant.
- TN status requires nonimmigrant intent. A green card filing can create problems for TN travel and renewals if it is not timed correctly.
- Spouses and children can go with the TN professional, but they cannot work on that basis.
TN at the Detroit-Windsor border
Detroit is one of the busiest crossings between Canada and the United States, and many Canadian engineers, nurses, and other professionals commute from Windsor to Michigan employers. We prepare Canadian professionals for the crossing and help Michigan employers keep their TN workforce stable. See our Detroit page for more on how we work locally.

Common Questions
Not as of September 2026. The United States did not agree to extend the agreement for a new term in July 2026, so the parties now review it every year. The USMCA and the TN category remain in force, and the TN rules have not changed.
Yes. Canadian citizens can apply at a port of entry or preclearance location with a support letter and proof of qualifications. The officer decides on the spot, so the documents must be complete.
It is possible, but the timing matters because TN status requires nonimmigrant intent. Many TN workers move to another status, such as H-1B, before a green card case. Get advice before any filing.
