I was working with employer A that has TN stamp valid till May 2021. I recently went an applied for a new job and got a new TN visa valid till July, 2022. I am not enjoying working at employer B and want to go back to employer A. Do I need new TN visa for Employer A or Can I continue with the old passport stamp? Does new TN visa with employer B voids my old TN Visa with employer A. My I-94 does not mention any employer name.
Thanks for your help!!!
