As I recall from working with a few Canadians over the years who had to do regular renewals, the TN visa has a very restricted and particular set of job.titles with specified duties which are allowed. The main one for revs is the Programmer Analyst ( I forget the exact title). One coworker was required to show his job.description for a renewal and had.to have the company revise it several.times.to satisfy the bureaucracy.
