How long for an AROTC transfer request to be approved?


Nov 4, 2017
My son won a 4 year AROTC Scholarship and accepted it to one of the 3 schools that was listed. He has since been accepted to his first choice school for an entirely different major which is why the school did not make his list for the Scholarship. He has requested a transfer to his first choice school, uploaded the Letter of Acceptance from the school and Transfer Request...any idea how long it will take for him to hear an official decision? The ROO at the University of his choice said that it would not be a problem...but I understand that they do not always know...any input would be appreciated!
Should he contact the ROO at the school he currently has the scholarship with and let them know he has requested a transfer? Or is it best to let Cadet Command handle it?
