CSS Profile - Before or After Acceptance?

Hello, I’ve recently realized I need to submit my CSS profile to four of the schools I’ve applied to (UMD apparently doesn’t require it). My question is: should I submit it before or after I’ve been accepted? It’s considerably pricy and I can’t seem to find deadlines for any of the schools I’ve applied to. Any advice is appreciated. Thanks.

Is there a specific date the Profile is due? If there is no date on the web site then call admissions and ask about when it would be due.

Are you a transfer student? Most people apply for financial aid with (or even before) the application is sent in so they will have a FA package to compare when acceptances start arriving.
