Hello everyone, please help. My wife entered US with BCC visa from Mexico in 2008, and she has been (overstayed) in US ever since. We recently married and I noticed that the I-130 form ask for I-94 number, but she lost it. Do anyone know what I should do? I was thinking about applying for I-102, but she doesn't remember exact date she entered US or the date she received her I-94. Thank you very much for your help.
