I am a first-year PhD student in statistics, but plan to apply to computer science graduate programs in the fall. Two of my recommenders, however, are professors who I would like to advise me if I were to stay in my current program. Because I have a limited computer science background, there is a decent chance that I will not be accepted to good programs and will therefore stay in my current program. I am worried that this will make it difficult to work with these professors if I do end up staying.
Is this likely to be a problem? What's the best way to obtain a letter of recommendation while keeping the door open for that person to be my advisor if transferring programs doesn't work out?
