In this article, I examine how open borders can serve the idea of global distributive justice by asking how or how not the existing practices of immigration to rich countries may contribute to global economic redistribution. There are two observations. First, migration is not the redistributive option that anyone has an equal access. In order to make use of migration as a means of global redistribution, rich countries need to provide a chance to migrate to those who cannot afford movement by themselves. Second, as long as brain-drain problems happen, what the perspective of global distributive justice requires is the compensation for some educational cost of raising professionals or some control of their movement. Immigration admissions largely focusing on getting highly skilled professionals may not serve the idea of global redistribution
