when preparing I -485, I couldn't find my I-94 for change from F2 to F1 in Mexico obtained in aug. 2007; I do have the F1 visa. In Nov. 2007, I crossed the canada border and I got another F1 I-94.
Do you think I still need to file 102 form to replace the missing I-94? - You don't and you can't (宰你個冤大頭的 I-102)
I guess the missing I-94 must be wrongly collected when I crossed the Canada border.
I contacted the international office of my university, they have a copy of my missing I-94 mentioned above, but they don't have the back page.
Do you think it's a good idea to send this copy (front page only) with my I-485 application? - Fine
Thanks a lot. I will file 485 tomorrow.
