Canadian family lives in the US now. I work under H1B (with an approved I-140 sponsored by the employee) and my spouse works under TN. I have taken a job offered in Canada (with a better salary, career future, and retirement plan) and will resign my US job in a month. My spouse and kid want to stay in the USA for a few more years so my kid can complete his high school. I plan to drive between Canada and US every week as the new job in Canada is not far from my current home (rented, not owned) in the USA. TD could be the best option for me to do so. Although my US employer will close the sponsorship after I resign, I do have an approved I-140. Is it possible for me to get TD status? If it is possible, what kinds of documents could help me to get TD? Any suggestions are welcome and thank you!
