Joel, to add on, from my experience as a former ROTC PMS and current JROTC instructor, Cadet Command generally approves the majority of scholarship transfer requests (probably 10 of 10 requests during my combined tenure) if you follow the process described in this post, especially since you have not been admitted to one of your schools. Think of the schools designated on your portal/offer letter as the Army's attempt to shape the cohort and ensure most ROTC programs have a equitable and healthy amount of potential contracts to start the year. The only time they may not support a transfer is if a school is getting close to filling its contract mission with scholarship offers. I have two former JROTC Cadets at VA Tech now on ROTC scholarships, so if you do request to transfer there, ensure you understand that the Corps/SMC experience will be much more intensive than a traditional ROTC program. It also helps to contact the ROO at the school you want to transfer the scholarship to and they should help you with the process.
