Abstract
Many people want to live in liberal democracies because they are liberal and democratic. Yet it would be mistaken, indeed naïve, to assume that this applies to all would-be residents. Just as some inhabitants of liberal democracies oppose one or more fundamental liberal-democratic values and principles (e.g. the rule of law, freedoms of conscience and speech, rights to private property and to political participation), so there are foreign would-be residents who do so, who might include individuals with e.g. Jihadist, Neo-Nazi, and radical anarchist views. Proceeding on the assumption that there exists no unconditional moral right to immigrate, this article asks whether it is ever morally permissible for liberal democracies to deny residence to nonnationals based on evidence that they personally hold extremist views. I argue that this is sometimes the case. Specifically, my contention is that even if we adopt a cosmopolitan perspective on which states are not allowed to prioritise the interests of their own citizens and residents over those of foreign nonresidents, there are two conditions under which such exclusions are justified even when refugees are being refused admission (although, as I suggest, states might be morally required in such cases to admit other refugees instead).
