The Danish Immigration Service has an agency that collects background information on conditions in the country of origin of asylum applicants. This specific information is used to process asylum applications and other types of cases at the Immigration Service. The Immigration Service also collects information from field trips and fact-finding missions. Some of these are conducted in cooperation with the Danish Refugee Council (DRC). Findings from the missions are presented in reports which are available to the public. All reports produced by the Danish Immigration Service are available (in English) here.
DRC also collects background information on the countries of origin of asylum seekers and refugees in Denmark. Some of the most significant countries are described in country profiles, which aim to give a quick overview of, among other things, the political situation of the country in relation to Danish asylum policy. The information in the country profiles is used, for example, to file complaints to the Danish Refugee Appeals Board on behalf of an asylum seeker . The country profiles are available (in Danish) here.
