A professor offered to fly me out to their school for a visit, and said they will pay for the flights/hotel/everything. They've scheduled for me to talk to a bunch of students, post docs, and professors, and everything seems like a normal, standard campus visit, except... I haven't been accepted by this school yet! :S
What does this mean? The professor is the same one that I had an REU with, is he just acting on his own? Does this mean I'm likely to be accepted? Is this an interview? It's been a week since they contacted me about the visit and still nothing official from the school. Freaking out a little. I really want to go here!
