I lost my I-94 at the custom office while coming back from Nepal this summer. I had been putting off getting a new I-94 until now but now my school wants to see a copy of it. I tried calling a few immigration offices regarding this issue but they keep transferring me to some other offices and I haven't been able to get any help. Does anyone know the appropriate place to contact to get a new I-94? Also, how much does it cost to get a new I-94.?

Any help appreciated.
