I sent a copy of my passport, I-94, my expired visa,my middle school report cards and standardized test scores (I think from 07'-10''), and my attendance record (to prove presence on June 15th). I can't remember if I sent my freshman and sophomore year report cards. I'm guessing I either need to prove I'm still in school, they couldn't interpret my attendance record, or I didn't send enough evidence for the 5 years of continuously residing here.
