i have mine for the same day. ive been doing my research, watching YouTube videos along with the information on the interview notice to help me prepare.. good luck @Li Tao

from what ive heard, we might spend so much time preparing only for them to ask us only few questions without even looking at the ducuments we brought lol. u basically want to take everything that you submitted to uscis. originals and copies. (an organized file helps u alot) u also need any notice that youve ever received from uscic, id’s, photos of you and your spouse, any other joint ducuments that u and your spouse has accumulated over the time period of waiting for your interview. joint account. joint insurance, taxes, ect… there is alot more that i did not mention but the information should be on your notice

base on vawa right

they can ask anything. be ready to answer any kind of question.
