My US employer submitted a I-129 to extend my current TN visa. We received the I-797, notice of receipt which will allow me to work for 240 more days while the application is being reviewed. I need to travel to Canada and I'm concerned about re-entry into the US. Does my employer need to withdraw the I-129 application and let me apply at the POE? Or can I just show the documentation (e.g., I-797 notice of receipt, copies of letters, degree, etc.) at the POE. My current TN is now expired.
Thanks
