No, I have not had any issues or violations when work in USA, not even a traffic ticket. I am working in USA with a TN visa and recently have my TN renewed. I used to commute to work from Canada for the last 20+ years but stopped crossing when my company filed I-129 to renew TN for me in early Feb. this year and stayed in USA ever since then. I am wondering if TN (non-immigrantion intended visa) is the source of the problem.
