Hey I've been looking into this process myself, and I saw that at the end, you have to request a release from your current PD.
What happens if they refuse? Do they have the power to trap you in the program and refuse you from leaving?
Also, at what point are you supposed to contact the dean? At the beginning when you're considering a transfer? Or at the middle? Should you be contacting PD of the program you're interested in on your own? What if they decide to write your current PD?
I have a lot of questions.. if there's someone who's gone through the process wouldn't mind communicating, please let me know by pm!
