I initially came to the U.S. under F1 and then changed to F2 after graduation. Now I got admitted to a school in a totally different major and applied to change my status from F2 to F1. I've got the Request for Evidence . The first one in the list is "EOS/COS - Extended Stay in US or Leave of Absence". It says "A review of the record indicates that you have been away from your home country for an extended period of time. Submit documentary evidence that you have been authorized vacation or leave of absence for the period of time already spent in the U.S. and requested on the application." I've been in the U.S. for all those years and those "vacation or leave of absence" don't apply to me. How should I respond to this request? Many thanks!
