My AOS interview is coming up and just realized that my I-94 is missing. I just came back from vacation and last time I remember seeing it was at the airport. I didn't go overseas, so they didn't take it at the ticket counter. I must have dropped it somewhere since the perforation was torn. I still have a copy of it. Any idea what I could do? I don't have enough time to get the replacement card as my interview is in a week. Can I just take a copy of it with me, or should I reschedule the interview and file for replacement?
