I agree kar. Send the deposit to OSU. That covers both ROTC programs and locks in AROTC plan if needed. You should accept the AROTC scholarship if you haven't already. Now you can wait on NROTC and Foundation, and if they work out you notify AROTC and perhaps OSU that you've decided not to use their excellent offer. If you can't have plan A locked in, this is the next best thing. Congrats to your DS.
Thanks Kinnem!!! Followed every bit of your advice and the OSU ROO was just on the phone this morning saying it was the exact right thing to do! YAYYYY!!!
