This paper presents a two-period human capital investment model, which is used to study the optimal investment decisions of credit-constrained married immigrants relative to single immigrants and native couples facing a perfect capital market. The model predicts that: (1) The comparative advantage in investment in local skills of one of the spouses may emerge from his/her higher growth rate of imported human capital. (2) The optimal investment of each spouse is non-increasing in the level of imported human capital of the spouse with the comparative advantage in investment, while it is non-decreasing in the level of imported human capital of the other spouse. (3) When two immigrants get married, the spouse with the comparative advantage in investment invests more than when he/she was single whereas the other spouse invests less.
