International migration research increasingly addresses the complex mobility that occurs in transnational contexts. Authors who study ties between migrants and their parents often focus on money transfers and financial investments. However, exchanges within transnational families are broader and multifaceted, and include an important care dimension that is shaped by gendered and cultural social codes. Studies show that women are often engaged in caring for their older parents even from a great distance. They develop strategies to attend to the well-being of their parents, including relocating them in order to bring them in closer proximity. While the economic aspects of care work within transnational family networks are well-researched, we lack knowledge about the impacts of national migration regimes on the abilities of migrants to take care of the parents that they have left behind. This chapter points to some areas in need of conceptual development in addressing this gap. We draw on existing literature and legal documentation to explore how some legal contexts (e.g., selective immigration policies, limited family reunification) restrict care circulation within transnational families and tend to reinforce inequalities between advantaged and disadvantaged migrants, particularly women. We emphasise the need for research concerning transnational family care circulation that focuses more on South-North migrants whose economic and legal situations are particularly precarious.
