I got into one of my top schools on December 15th, but have not received an interview yet at the other (UMICH). I am in-state so UMICH would be cheaper and most likely be my #1 choice if I were to get an acceptance. Is it fair to send a letter of intent at this point, with no interview? I was also thinking that perhaps admissions would already recognize my increased interest in the school anyways as an in-state applicant, so I wasn't sure if sending an LOI would make any difference.
