I plan to apply MD/PHD next cycle (year from now) because I am going to do a masters program first. I graduated in the spring and will be going to a new university in the fall. I have established some great relationships with professors, but don't know if I should ask them to write letters in person before I leave, or in another year (when I will be in another state). I am planning to use interfolio, so it could keep my letters ready to send. Should I ask now or later?
