Access to health-care services in Denmark is dependent on migrant status. Emergency care is available to all migrant groups though people not officially residing in the country may be subjected to payment. For regular immigrants and persons with refugee status access to health-care is regulated by The Health Act, whereas access to non-acute health-care for other migrant groups such as asylum seekers, undocumented migrants and persons subjected to human being trafficking is mainly regulated by The Alien Act. The most vulnerable migrant groups are the ones with the most restricted access to care.
