well it depends in which city will you be moving to, I can tell you right now Jeddah is the best place over there, it is the most liberated city in the country, a lot of things to do and places to go and because the country is booming economic wise, shopping malls are everywhere, million of beautiful of restaurants, cafes and lounges to hang out in, Obhur creek has a lot of nice complexes with beautiful beaches and some are only for foreigners, if you attended an international school, which i recommend you to do so you will meet a lot of people from all around the world and will make a lot of friends, most are American.
Weather is unfortunately hot humid and sunny around the year, occasionally chilled and it rains once a year for two minutes if you're lucky.
there is two private medical schools for girls and i don't recommend any of them, higher education is not bad but you can get much better in the US. I myself left the country to study in the US.
basically it is going to be hard in the beginning to fit in, but if you knew the right people to hang out with I can assure you that will have the time of your life.
