International return migration is conceptualized and modeled as the outcome of two opposing forces: assimilation into the host society and attachment to the home country. Assimilation is a cumulative learning process that, over time, lowers the tendency to return; attachment levels are less predictable: they might decrease, increase, or remain constant over time. From this proposition, we derive a generalized gamma function for the probability density function of the duration of stay, allowing for increasing, decreasing, and constant hazards of return. The applicability of the model is explored using the case of foreign migrants returning to their home countries from West Germany.
