Hi everyone, since letters already seem to be going out, this might be a little late, but I thought I would share some words of quasi-wisdom from someone who has been in your shoes. I applied in the 2012 season and lurked on gradcafe heavily while waiting to hear from schools. I am now happily studying at an Ivy with full funding, stipend, etc. etc. Here are a few things I've learned about the application process from my own experiences and seeing the acceptance process at my program.
1) Visits and contact with POI. There is no magic formula. I know people who have visited every program they applied to, talked on the phone or Skyped with their POIs, emailed, and any other combination of these methods. Depending on your POI's personality, this may or may not matter. Full disclosure...I did not communicate with any of my POIs. I throroughly researched their work and the direction their current scholarship seemed to be going, in an effort to determine scholastic compatibility. If you can do it, visiting is a great way to get to know departments and POIs, but it is not necessary. If you do plan on visiting, go in early January right before decisions are made. However, I have heard of professors souring on students they were previously interested in after a visit. In the words of RuPaul, "don't fuck it up"
2) When choosing where to apply, check the department website for the number of students your POI is currently advising. If they've taken 1-2 students each year for a few years there is a very good chance the department will let someone else bring in a student instead of them. This is not in stone though. If they are really passionate about you, and have some power in the department they will make room for you.
3) Once applications are in, each department works a little differently. Some professors will look through every application that might relate to their field, others will allow for a shorter pile of applications to be presented to them and then choose from there. Each year a different number of students are admitted. If last year's group of incoming students was large, chances are not as many will be admitted the next year, and visa versa. As I said earlier, departments try to divide up students among faculty pretty evenly. If a professor doesn't currently have many students in coursework, they will likely take 1-2 students in a given year. All the faculty meet together to decide who to admit. If your POI wants you, they will come to the meeting ready to sing your praises, and will likely make alliances with other faculty to vouch for one another's students. Final decisions are made together and then sent to the Dean who gives final approval. Because of this last step, which may take a few days, ideas about the timing of CAA and the sending out of acceptances is kind of bunk.
4) The only letter that matters is yours. Gradcafe can be good for solidarity in this stressful time, but don't put too much stock in what people report for acceptances and rejections. It isn't over until YOU hear from the school, not when everyone else does
I hope this is helpful! Best of luck!
