Volunteering is considered the outcome of social networks between volunteers. This article aims to contribute a theoretical understanding of social networks as a mechanism providing social capital (benefits) for volunteers donating their time to help refugees. For this purpose, the article conducts a combination of basic social network theory, structural hole theory, and social capital theory. Applying these three theories helps to explore who can benefit from the structure and how, and then both structural hole and social capital theories explain the way in which the network structure produces social capital benefits. Based on these theories, social networks, both direct and indirect ties can provide benefits to volunteers who help refugees. Volunteers can access and shars different types of information. They can exchange ideas with other volunteers relating to volunteeing. Then, they can do volunteer work that benefits volunteers and refugees.
