but in the case of SA appointments MOC's are part of the process and should be included in issues regarding appointment status.
The MOC makes a NOMINATION. USNA , and perhaps other SA's , give the MOC an opportunity to notify the Appointee as a courtesy. MOC should not be, and most probably carefully avoid, further involvement in the Admissions process.
Sure, you have the right to contact your MOC, but actions have consequences. I participated in responding to a MOC inquiry when I was on active duty, and the reaction from the entire Chain of Command was to justify our actions, rather than try to address some perceived injustice.
(In my case it was easy , a young enlisted sailor sent her Congressman a letter claiming she was in the Philadelphia brig "against her will." As Squadron Legal Officer, I had to draft the lengthy response detailing each step of the process leading to her brig time. (That was after the Skipper shot down my initial response " Dear Congressman XX X, most people are in the brig against their will; there are very few volunteers."). There may be times when it appropriate to contact your MOC, but only as a last resort.
The bottom line, there is a lot of speculation and uncertainty on this thread, including trying to diagnose a medical condition with very limited information (sticky rice ?) and relying on a portal change notice, INSTEAD OF PICKING UP A PHONE AND TALKING TO THE SOURCE. There are some bright young men and women in the Admissions Office (I've met many of them), and if they don't have the answer , they all understand the 4th basic response (one of the first things learned on I-Day). "I will find out Sir/Ma'am." USE THE CHAIN OF COMMAND !
This is an unfortunate situation, but certainly not the first time a last minute medical issue has happened. Starting with an LOA, and subsequent offer of appointment from Florida (which is pretty competitive), it is obvious OP DS is a first class kid and USNA wants him to attend. They aren't looking for ways to keep anyone out, but they aren't going to admit someone until cleared medically. All parents have to understand...this isn't just sending your son/daughter to college. The Navy is investing a lot of time , money and effort into turning your kid into a Naval Officer. One of the first lessons to understand about the Navy is that the needs/wants/desires of the individual will always be subordinate to the needs of the Navy.
For OP - there is some good advice in this thread. First, don't down play or think this isn't a serious medical issue. It is serious as long as the Navy thinks it is. Get all the information about your Son's condition you can. Research the Navy Medical Regs to find out whether the condition is in fact a permanent DQ, or waiverable. Enlist your Doctor's help in presenting this to USNA as favorably as possible. Next, it may be too late for this year .. things like this don't get resolved overnight, but talk with Admissions about an LOA for next year. (And if you get the LOA, that would be certainly a good time to write Sen. Rubio and tell him what happened, because I would be willing to bet he'd put DS on the top of the list for next).
Finally, look forward , not back - I really like the Victor/Victim comments someone described in an earlier thread about Plebe Summer , and will probably refer to them a lot on this Forum in the future -that's a good way to look at life in general. Pick up the phone, call Plan B and see if DS can get in (this might be a good time to avoid mentioning it may only be for a year); I would expect most colleges would love to DS , and can find a space for him. If not, make this a productive year - take classes at the local Community College, work, etc. Those credits usually transfer. Finally, if DS ultimate goal is to serve as a Naval/Marine Corps officer, there are several ways to get there, and when they pin on the bars, all O-1s are the same.
Yeah, its a gut shot. I really feel for DS and your family, but its not the end of the world no matter how it works out.
Good luck.
