This article examines the key ethical questions in the design of labor immigration programs. We propose a two-dimensional matrix of ethical space that isolates a number of different ethical frameworks on the basis of the degree of consequentialism they allow and the moral standing they accord to non-citizens. We argue for the rejection of extreme ethical frameworks and propose criteria that should guide national policymakers in their choice and application of a framework within the ethical subspace of moderate consequentialism and moderate moral standing for non-citizens. To translate these “ethical guidelines” for the design of labor immigration programs into policy practice, we advocate new types of temporary foreign worker programs. In contrast to many existing and past guest worker policies, the programs that we propose would more actively promote the interests of migrant workers and sending countries by more clearly defining, and more effectively enforcing, certain core rights of migrant workers.
