I will be applying to graduate schools in math this fall; is it a good idea to visit them during the application process? I have heard people give different answers to this question, and I would like some more opinions. I have in mind only the schools in the area, and I don't plan on going too far out of my way to visit. On the one hand, visiting, talking to faculty, and sitting in on classes would be interesting and would give me a better idea of which of the programs I would rather attend. On the other hand, some might argue that the time to do this is after I have been admitted. Visiting schools might also help with admissions: if I talk to and make a favorable impression on faculty and they end up on the admissions committee, it may set my application apart to some small extent. But I have also heard that some professors don't like students to visit before they have been admitted, and may even try to balance out having met with the student by judging the student's application more strictly. So, I am not sure what to do. What do you think?
