The immigration problem, which has been debated in the United States for over a century, is not likely to go away--least of all with the numbers of refugees and displaced and impoverished workers continuing to mount worldwide. The current bitterness and legislative stalemate over immigration policy are indications that new approaches to the issue need to be found. Removing himself from the specifics of the current congressional debate, Mark Gibney asks whether we are addressing the right questions and employing the correct criteria under our present admission practices. From a political-philosophical standpoint, the author looks at the fundamental social and moral questions that should be at the basis of any immigration policy: how do we distinguish between members and strangers, and do some strangers have more compelling claims than others for admission to this country?
