Hi Everyone! New here and this is my first time posting on the thread. I was wondering what you all think about the "virtual visit days" coming up and if anyone knows what to expect. I have been invited to a virtual visit day in Feb. and this is my first application cycle, so I'm not entirely sure what a visit day, or virtual visit day, will consist of. My program also hasn't specified the timing, only the date, is it usually an all-day event? And if so, do you think it will be an all-day event considering the new virtual format? Thanks!
