Hi all, So I was accepted into a PhD program (offered a 5 year RA), visited the school a few weeks ago, and emailed my acceptance to the POI yesterday. The POI then immediately asked me to call him as soon as possible and explained that he was considering accepting a job offer in New Zealand. He said my offer/project would be carried over to this new school and he is extremely sorry for not mentioning this when I visited (he applied months ago and only heard back 2 weeks ago). He also mentioned that he wouldn't accept the offer, if I wasn't okay with it (which put me in a really uncomfortable spot). Also profs at my current school said it is highly unlikely that he would still be able to carry over the NSF project/funding I was offered to New Zealand. I already sent out my rejection emails to my other offers (I know, I messed up)... And I'm okay with New Zealand (if I'm funded), however this whole situation kind of rubs me the wrong way (as in why didn't he mention this previously? and why throw in the "fate of my career is up to you" bit?). So I guess my question is is this a common thing? I'm not sure if I really want to work with him now because this seems a little dishonest to me but I'm also not sure if I'm just being too sensitive and this sort of thing is normal. And also what can I do now if I resend my acceptance?
