Are “Doctors Without Borders” (MSF) doctors without a homeland? Based on fifty interviews, statistical data and a participatory observation, this article describes humanitarian mission conditions limiting local integration and suggests three forms of attachment: home (“break expatriates”), elsewhere (“multi‑homeland expatriates”) or nowhere (“duty‑free expatriates”). For the latter, MSF plays, until their departure from the organization, the role of substitute homeland.
