Clafford's research on transnational families has taken her to several countries, including the United States, Mexico, the Philippines, and South Korea. Her work in this area has focused on the ways in which families adapt to the challenges of living in different countries, and the ways in which they maintain their cultural and ethnic identities.
Clafford's work on ethnicity and migration has also taken her to several countries. In this area, she has focused on the ways in which ethnic groups negotiate their identities in new cultural contexts, and the ways in which they cope with the challenges of discrimination and racism.

She has also edited several volumes, including _Home and Its Meanings: Personal Narratives of Overseas Filipino Workers_, and _Mapping Transnationalism: The Social and Cultural Dimensions_.
