1842--wonder if that is your name to identify the attempted invasion of texas, and subsequent departure by mexico, or of the Citadel? Anyway, moving to your question. No reason to panic. As was explained to us, NWL is where everybody goes at some point in the process. Hold is a good thing. It means you have made the cut to be considered. Just because there is a hold does not mean there is not a space. It only means that decisions have not been made. At the DOD schools, they can make decisions from the nominating authority's group of 10. When they have all of the required information in the file, from the ten (or at least from those that are competitive) they can make a decision. At USMMA it is not like that. USMMA fills slots on a state basis. As a result, before any appointment is made, they need to be able to look at all of the applicants from that state. You are not even to the date where nominations are due, so no reason to worry yet. Now, does USMMA give out early offers, yes--but, there are not a lot of those. And, by now, those are all likely given. For the class of 2020, it seemed that appointments "rolled" across the country, during the time frame of end of March and early April. They did not make a lump mailing on one day. Then, there appeared to be a second round sometime at the end of April early May. So, If state A has 1o slots, and State B has 4 slots. State A is found to have 12 applicants that the school wants. They can take 10 to fill up the state. But, State B only has 2 applicants that meet requirements. They can then take the 2 qualified from State A and fill in the spots left open in State B. There are a number of states that do not fill their spots. New Hampshire, Vermont, and some others. The foreign territories and the foreign countries allowed to send kids sometimes do not fill up either. Some states have more than their number. Texas, New York and California are big groups. I don't have the numbers handy, but almost as much as 20% or so come from those three states.
So what to do now, besides wait. Keep an open dialogue with your admissions counselor, and, any others you may have had contact with at the school. Keep an open dialogue with the coach if there is one in the picture. They can help with information on the process and possibly progress.
