Congrats! I have also accepted this PI. I received my email the next day, but I know other people on here have waited longer than that. I also received another email yesterday about housing and at the bottom it said that we will be getting several emails with information we will need before we arrive. I hope this answers your questions!
congrats guys, I am really discouraged now that 3 people on here have gotten phone calls for that position and I am still waiting
