Tourists with passports outside the Middle East have no problem entering or exiting Ramallah. Make sure to have your passport and visa stamp with you. Even though you will probably not need your passport to enter, you will be required to show your passport and stamp in order to re-enter Israel. Once through the checkpoint, it is a short drive to downtown Ramallah. Bear in mind that it is illegal for Israelis to enter Ramallah, under Israeli law.
