Based on in-depth interviews with middle-class Korean professional sojourner migrant married couples in Singapore and their elderly parents, this paper examines how the cultural meaning and social practice of filial co-habitation and support have been transformed in an international migration context. Transnational co-residence and visiting among these families are examined and a differentiated and patterned organisation of support by sons versus daughters for their own elderly parents is demonstrated. Although the immigration regulations and co-ethnic community environments for older Koreans in Singapore pose a challenge to elderly parents, the family remains the most important nexus of care and support. By adopting ‘virtual’ and ‘actual’ co-residence strategies and deploying multi-purpose long-term visits by wives and children in Singapore to their elderly parents in Korea, and by remitting regular financial contributions, these families are able to maintain the cultural ideal of filial co-residence and support. However, the gendered traditional co-habitation ideal differentiates between actual and virtual co-residence. The actual co-residence pattern was mainly adopted by first sons/daughters-in-law couples and the elderly parents of the first sons, whereas the virtual co-residence pattern was mainly adopted by sons-in-law/daughters couples and the elderly parents of daughters. These results show that patterned two-way transnational mobility for providing care and support is shaped by cultural norms and the practical negotiation of family obligations.
