I have come to US on September 5, on F1 Visa. My I-94 is missing, but the stamp put by the DHS and CBP r there on my passport; my details have been enterd into the systems at the port of entry at JFK and must thus be present in the systems there. Can I go back to the airport to the CBP, fill a new I-94, give them photocopy of my passport pages with stamp, I-20 of my university and a formal letter stating that I am a full time student and the date of completion of the degree, and wait for them to check out and give me a new I-94?? Will I get my new I-94 this way?? Please answer as soon as possible!!!
