The simple answer is no. However, this visa/status is designed for “short term” work and not meant for a permanent placement so if the applicant indicates that s/he is filling a permanent and or intends to be in the job with no end date, it could be grounds for the officer to reject the application.

We have heard that some officers may reject the application after 4 or more times of renewals.

Just to clarify, prior to Oct/Nov 2013, TN visa/status was only good for one year. Now it’s good for three years.  That said, our experience has been that our team in this room has renewed our visa over 7 times (me 9) prior to 2013.

My point is this – if the officer believes the applicant has a job with no guaranteed end date, the application will likely be rejected. BUT the last time we checked, there are no companies in this world that would offer such a deal even for a CEO role of a Fortune 50 (they can be terminated too!).

Immigration attorneys or the employer legal counsel will likely advise the applicants that they could be terminated in 3 years time and that is their discretion.  The TN application letter will also clearly indicate that the role is for 3 years time.  Does this mean the company is obligated to fire you in 3 years time because of this statement in the application letter? Absolutely not.
