b. (U) Homeless Physically Present in a Third Country: Homeless applicants residing in a third country are processed at the same IV processing post as are nationals of that country. Posts must accept for processing any IV applicant who is physically present in their consular district, provided the applicant has the permission of the host government to remain there legally for a period sufficient to complete processing of the application. This does not include persons who have been determined not to be refugees, and who are subject to return to their country of origin.
