Hi Nelson, Thank you for your posts. They are so helpful. Context: I am Canadian citizen. I got my first TN valid for 1 year. My company is acquired by another company and my job and title will stay the same. Acquisition will close at July. My TN expires at September. Questions: 1. In September, do i need to ask acquiring employer to write a letter to POE requesting a TN Extension or New TN? 2. What determines the duration of TN? I read most people get 3 years. I try to estimate will they give me 3 years or 1 year again. Or did they give me 1 year because it was my first. 3. Is I129 or going to POE better? Thank you very much
