Allow me to not answer your questions, but rather describe my DS’s experience several years ago.
He received 4 yr AROTC scholarship to and was accepted to GA Tech as an OOS. For reasons I can’t quite recall, he requested to transfer the scholarship to Big 10 State U, also as an OOS. I think it probably had to do with $. At the same time, he requested to defer the scholarship for a year so as to do a gap year.
The first thing he did was contact the admissions department at the target school who really wanted him (unlike GA tech who really didn’t care). He humbly asked them to contact the PMS and ROO and put in a word for him. He then contacted the Battalion at Big 10 U, explained his plans and humbly asked for any help they could offer in the transfer.
Sometime after he went overseas for the gap year, I got a call from the ROO, who didn’t realize that DS was gone. His first words were something to the effect of “I just received a call from admissions and they really seem to want your son.”
As I recall the whole process lasted several months and the final word came sometime after the final Board.
I went through all that detail to suggest that your DS do the same thing as mine. Contact the relevant folks at the school he wants and let them know that his heart is set on that school and Battalion. They really appreciate certainty.
Finally, my DS had the advantage of transferring to a school whose tuition was about $15k/yr cheaper, which probably trumped his bonafides or lack thereof.
Best of luck and let us know the outcome!
