@Rachel n Tyler During our interview we did bring the updated vaccination which was handed to the officer in the beginning of the interview. I brought pretty much everything all the letters received from USCIS, NVC, all her Birth certificates and I-94, more pictures and etc but in the end it was only the vaccination and our ID that were needed by the officer. Most of the questions were directed to me mostly basic like where you met, how many times have you visited her.
I did post here how the interview went. Your more than welcome to ask me anything if I can be of any help. 😊
