You've requested advice. Honestly it is not clear if you want NROTC, a bit confusing why you are pushing for help from their cadre. From prior posts, you appear to have stated that you have higher-to-you interests in-hand and are pursuing other choices. You've been accepted to KP (King's Point, the Merchant Marine Academy). Your "number one choice" is Navy and you're awaiting decisions on your remaining SA applications or if not may want NAPS/ prep school . You seem to imply a visit during spring break would have sealed it for you at KP, had the world not tilted off it's bearing. But you're pushing for VT NROTC to help you with admissions. You are free to change your mind at any time of course - "that's your prerogative". Just don't waste their time if you aren't going there (please).
Assuming as fact that you actually want to use your National NROTC scholarship/ then there is nothing wrong with asking a ROTC unit for support. You've asked VT- a couple different ways. The silence in response was deafening if you listen for it. But now, like in Frozen recommend you "Let it go".
Pushing the Navy for urgency isn't often fruitful. recommend doing so rarely. My DS did it with his NROTC recruiter when he kept dropping the ball, as we believe DS would not have gotten his application finalized otherwise- now DS is living his dream. But that's an exception to a rule. today, NROTC midshipmen and future midshipmen "really" want to know about summer plans - NSI, Cortramid, Summer Cruises. Most midshipmen have not not asked once. A few are pestering their units or future units for details daily - the unit or Big Navy will tell the midshipmen when they are ready to do so. So goeth updates from big navy that the midshipmen perhaps would ideally in their minds like sooner. they wait, and adapt.
Good luck. Hope you are clear to yourself what you want for university, get it and Fly Navy. Thanks for your willingness to serve.
