It would be impossible for a volunteer to learn all of the customs and preferences of the various cultures from which refugees arrive. As you get to know refugees through friendship, you will learn more about their cultures. Refugees understand that they are entering into a new culture, and will therefore have to adapt to that culture (but still keep their own!). Their own culture is to be celebrated, but they will learn various American customs in order to thrive. For example, a refugee will most likely shake your hand when you meet them at the airport, even if this is not how they would have greeted you in their home country.
Listed below are links to information that will assist in better understanding and serving refugees.
You can also check out "EveryCulture's" website and/or Cultural Orientation Resource Center's website for extensive background information on refugees from various countries. The Joshua Project is another helpful site that discusses smaller people groups within specific countries.
