Dear XXX,
I am very sorry to inform you that we were unable to place you with one of our faculty members. You have an outstanding academic record that you should be proud of, indeed all of the members of our committee felt you were one of our top applicants. Unfortunately the excessive costs associated with accepting, and paying for, an international student for 5 years make placement very difficult. We are hoping that these extra fees will be reduced but that will probably be several years from now, if it happens at all.
Thank you very much for your interest in our program; we wish you all the luck and success in your graduate career at another university.
