I've started to hear back from some programs offering me interviews but I'm having a problem arranging my dates and travel plans because I haven't heard from other nearby programs (ie. two schools in same city). Is is OK to call schools and ask them about when they'll start giving interviews out? Is is OK to push the issue and try to get an early invite? What is your opinion about being patient versus being organized and trying to save limited travel money? Thanks for any help.
