Making corrections to my CSS before sumbitting my College Applications?

Hello,
I realized I made a mistake on my CSS, which I already submitted. I emailed each college my corrections and one of them said they I had to sumbit my college application first to be considered a applicant so they could process my financial aid. My other schools have not gotten back to me yet and two of my schools said they have received my corrections and haven’t asked about my college application. Is the policy different for each college? I’m worried the colleges that said they received my corrections also need me to first sumbit my college application.

You will need to ask each college what to do…and when.
