There is no typical American family. They are very diverse. They have different family traditions and customs. They are from many different racial and ethnic groups. Their religious beliefs are not all the same.
Some students are surprised because American families are so different from each other.
You will notice many cultural differences between your country and the United States. These differences will make your homestay experience interesting, sometimes confusing, and frequently enjoyable. Since you have chosen a homestay placement because you want to experience the U.S. family lifestyle, you need to expect a different way of doing things. It is easy to misinterpret a situation and think that it is bad or insulting when it is merely different than what you are used to. If you don't understand what you see or hear or feel, ask your host family or the Homestay Program Coordinator.
