Hi, I just got the TN notice of approval, I-797B form issued by USCIS, and plan to go to the US from land border with my whole family who needs TD status. My question is do we still go to the TN office in the border? Or we just need to show the border officer my I-797B form, and tell her that my family need TD status too, then go (like we went to the US for shopping)? Thanks a lot for the kind response.
