Hi, I have an approved I-140 in the EB1B category. For my I-485, I got a RFE to submit proof of nonimmigrant status between 2003 and 2010 (when I was a student and postdoc). I have the I-20 for 2004-2009 (Ph.D.) and the I-797 for 2009- 2010 (H-1B for postdoc) but I can't find my first I-20 for 2003-2004 (the school doesn't have it either). I also don't have any saved I-94 copies from that time. Any suggestions for any alternatives? I will appreciate any advice. Thank you!
