I believe you should have completed the "Placement Change Request" to move your scholarship to Penn State. IMHO, I would move the scholarship to Penn State, since it is the sure thing. If you get into Villanova then try to transfer it back. You can also contact the battalion at Villanova to see if they can provide any assistance in getting you off the deferred list.
Here is a post from @NavyNOLA
from this thread: https://www.serviceacademyforums.com/index.php?threads/wait-list-question.53528/
There are two forms available on your son's NETFOCUS portal: the Placement Change Request and the Wait List Request. They have two different purposes.
The Placement Change Request is a request to immediately change placement from school X to school Y. If school Y has openings when the request is submitted, the student will typically be moved in short order. If the school has reached its freshman scholarship cap, they will not be.
The Wait List Request is designed to allow students to join the wait list of up to three other schools while still remaining at the school where they are currently placed. Current placement will not be changed. The three units whose wait lists you join will be notified, so they may reach out and contact, but you're in no way moved to their units. Towards the end of the scholarship season (late April-ish), the Placement office in Pensacola will contact students who are on wait lists and offer them the possibility to transfer their placement (assuming there are openings at the schools), if they desire to do so at that point. A student can say yes or no. Generally, Placement gives them a number of days to respond to the offer. If they say yes, placement is adjusted to the new school.
The benefit of a Wait List Request is that it gives a student somewhat preferential treatment late in the scholarship placement process when many students want to move around schools. They would be given preference over another student (who didn't complete a Wait List Request) to transfer into school Y. Keep in mind, though, that a school may fill up anyways during the months of January-April from students being placed there directly from the boards, and then the Wait List form does you no good. However, completely the Wait List Request can't hurt, it might give you a couple extra options down the stretch, and you certainly won't be moved without being asked first.
