Is it morally okay if I list this $100k grant under my achievements?

I agree with all of the posters here.
You are starting to burn bridges. You need to be transparent.
You’ve already been denied by Stanford and Columbia and don’t seem to understand that changing your immigrant status isn’t going to get you into a better position for admission to those schools.

Your postings seem to lead to the fact that you ARE prestige-hunting. The elites can smell this a mile away. They will ask the same question: Why is he transferring? (You are avoiding the question here, otherwise your response would be transparent.)
If we are all seeing it, then you can bet that the admissions “radar” will spike with your need to reapply and get a “name” on your resume.

You didn’t like being rejected, and you didn’t accept that these tough schools rejected you. Your attempts to transfer now says that the committee was wrong and that you know better. Doesn’t sound very “Cardinal” to me.
