The e-mail was from my POI! The e-mail sounded like it wasn't personally written by him, like it was a formal paragraph invitation, but my POI has really been my only point of contact (I have never received any e-mails from 'Brown Psych'). But the visiting day isn't until February 19, so I'm sure not all invitations have been send out!! Good luck & I hope that helps
I had three formal interviews with different faculty members at Brown and received an invite to their formal visiting/viewing day. I also applied to BU but have not heard anything from them. Good luck!
