Here in the same boat. Waitlisted again without interview. I am still in this mood to stay strong till the end of admissions process because I believe that time will tell. Perhaps I, an international applicant, am seeing my deadline to wait the school's call June 1st. Later than that timeline, I suppose my visa processing would be in a big big trouble.
Besides the timeline for visa, housing, etc, the practical problem I face these days is I am not sure anymore how to strengthen my application. I thought I poured everything in the waitlist essay, but it probably didn't caught sights of the adcom. I submitted only the waitlist essay and explained the adcom I can't take the gmat anymore which they required me to take a higher grade. Do you think I need to prepare more such as letter of recommendation? I really have no idea at this point. Any comments is warmly welcomed. Thanks.
