Reading through this thread, I’m really nervous about my inland application that I just sent in. I realized I probably messed up the IMM5406 form. Everything was right except my oldest sibling who I don’t really know or have contact with (she’s 25 years older). I had just written her city and state and email (we’re from the US). I didn’t realize it was so detrimental to have the exact address... Now I’m so nervous that isn’t enough. Is there anyway I can send in a corrected form? My heart is absolutely breaking at the idea of waiting months on an error I already know exists.
