The cost of healthcare off-campus will be higher, but it is good to know about your options. Private doctors in the US have regular office hours (usually 9 to 5) when you can see them by appointment if there are no emergencies. For minor emergencies, you will find clinics open round the clock, even on holidays that will treat you without appointments. For serious emergencies, you may need to call an ambulance to take you to the emergency room of your nearest hospital. These emergency rooms are fully equipped to deal with life-threatening illnesses, and are also more expensive.
