Researchers are increasingly embarking on international qualitative health research projects, where unknown social structures and government systems make inquiry uniquely challenging. In this article, we document our experiences conducting two related studies on HIV/AIDS in Northern Vietnam. We describe how our research relied on harnessing the social capital of vital community stakeholders, such as key informants, interpreters, and host organizations, to effectively engage with government bodies on a macro level and with local communities on a microlevel. By highlighting our processes, pitfalls, and successes, we provide current and future scholars with strategies to use when conducting cross-national field research.
