Are there anything like some colleges (like Yale) doesn’t ask for financial aid while the admission process.If you have the acceptance they give you the aid you need. Is it easier to have scholarship this way? Are there any other colleges has this process?

I’m in the same boat. Loads of colleges have that process, the important thing is to ask the college before you apply. Always communicate with colleges and find out about the entire process of admission, then ask about financial aid. If a college won’t tell you about it, then its not worth going to.
