In my original application I only sent my diploma hoping it would count for residency from 2006-2010 (those are the years I was in HS) and proving I graduated high school (reason why I didn't send a transcript is cause my HS was closed in the summer I couldn't get intouch with them) I seen this RFE coming and they said the diploma doesn't prove residency through my years in high school so I gotta send my transcript which shows I was there every semester for the 4 years and I also managed to get a letter from the records office vouching I been there to go along with my transcript
