Abstract
This article discusses cosmopolitanism as the moral foundation for access to health care for migrants. The focus is on countries with sufficiently adequate universal health care for their citizens. The article argues for equal access to this kind of health care for citizens and migrants alike—including migrants at special risk such as asylum seekers or undocumented migrants. Several objections against equal access are raised, such as the cosmopolitan approach being too restrictive or too permissive, or the consequences being undesirable; but the objections are largely refuted. Some special cases in which a restriction of equal access to health care might be justified are described: humanitarian crisis, short term tourism, and the case of a migrant or refugee who will stay only very briefly on a state’s territory.
