USCIS I-129 for First Time TN Applicant
We went to US Consulate, Ottawa and got my wife's TD visa stamped in her passport. Very straightforward, took just 2 days to get the stamping done.
Before travelling back to US, detached the new I-94s that came with the 797 A approval notice (bottom portion) and stapled it to the old I-94 (valid until Jan 30th 2018) that is there in the passport.
