The current situation caused by COVID-19 worries me, too. At the present, I have a funded offer and two waitlist spots (in fact, I've decline a funded offer and a waitlist spot). It's very probable that I will accept my present offer, but I dont't want to make a snap decision before getting any news from another two programs. (I'm sorry but another two programs are also my dream choices).
So, should I sit to wait for possible news? Is it better to solicit the two programs and ask whether they plan to freeze admission off the waitlists? I'm concerned that my acts will cause some terrible consequence for me, though I realize that it may be a long shot that I could be admitted off the waitlist.
