I do not believe any school will require you to make a deposit without first having given you your scholarship. If a schools deposit deadline is approaching and you've been accepted but you haven't heard anything about money, I would imagine they would be very generous about pushing the deadline back for you. Likely, you'll be making a decision without having all of your options in front of you, unfortunately.

you can ask for an extension, but this is on you. Applying March 15 is really late. The schools aren't doing anything unfair to you by not giving you a lot of time to decide. You could still wind up with some good options, but applying late is bad for a lot of reasons, and this is obviously one of them.
