What to tell the Dean when transfering schools

<p>Ok so I go to a college and I just was recently accepted into a foreign medical college. I wish to transfer now but don't want to tell the Dean becasue I might want to come back if everything doesn't work well. So I was wondering what I could tell the dean other than I wish to transfer. Also in college is there something as an indefinite leave of absence????</p>

<p>Please respond ASAP my meeting is tomorrow early in the morning so I need answer by then!!!!!!!</p>
