@CEOSandeep if you meet the stats of a college you applied to, applied within the priority deadline and don’t have any thing on your application that would knock you out of the running (things like felonies, cheating, etc.) then you might have grounds for an appeal. Perhaps you can contact your admissions counselor right away as a first start and get some feedback.
Question: You said at post #8 that you put biomedical engineering (CSE) as your second choice. Were BOTH your choices CSE or did you also apply to CLA? That actually does make a difference. Admissions makes all decisions with their own yield in mind; therefore, they will sometimes admit to CLA when it isn’t specified but not always - it really depends on what they think your interests are. If they thought you would ding them rather than enroll in CLA they may have a reason to waitlist (assuming you didn’t make the cut for CSE, of course).
