This paper investigates human capital investment of immigrants whose durati on in the host country is limited, either by contract or by their own choic e. The first part of the paper develops a model which distinguishes between temporary Migrations where the return time is exogenous or optimally chose n. The analysis has a number of interesting implications for empirical work , some of which are explored in the second part of the paper. The analysis focuses on language capital and tests the hypothesis that country specific human capital investments are sensitive to the duration in the host country 's labour market. The results show that the acquisition of language capital is sensitive to the intended duration in the host country.
