Hi -

I am going to India for visa stamping next month. I have two i797s - one thru April 2017 and the extension from April 2017 thru oct 2019. I initially took an appointment with my existing i797 (before I got the extension) - both ds160 and ustraveldcos profile has the i797 petition # ending in April 2017. Questions:

1) I think I need to update both Ds160 and ustraveldocs profile with new i797. yes or no?
2) I filled in new ds160 and updated my ustraveldocs profile with the new nds160 confirmation #
3) However I cannot find a way to update my ustraveldcos profile with my new i797. How do I do that?
