Asking same professor for rec letters for 2 different grad programs? I'm an undergrad applying for graduate programs next year. Is it a bad idea to ask the same professor to do two different letters for two different programs (Philosophy programs, and Law school)? My gut says no, since this would require the professor to kind of "lie" to each grad program about how dedicated I am to each. However, I do know this professor very well as I did research for him and the programs are somewhat related. Thanks!
Not at all.  We realize that students typically apply to more than one program.  I encourage my undergraduate advisees to apply to five or six graduate programs.  

Given that reality, I don't mind writing a letter of recommendation and submitting it (with few changes) to a half dozen graduate programs.
