Although foreign workers contribute to the economy and society, their lack of citizenship renders them unequal, vulnerable and exploitable. In this article, I suggest that the citizenship principle of jus domicile can address this aspect of inequality and exploitation experienced by migrant labour. In addition, I argue that the jus domicile principle should be combined with open borders. In making this argument, I draw on a dialectical methodology and a diverse literature on social justice and liberal political theory. The model I am developing is not necessarily for immediate policy implementation but rather presents a vision for a future of free mobility and settlement.
