These children are part of migrant population that most often comes from African and Asian countries and they started coming to Croatia in 2015. Croatia is one of the countries that they are passing trough on their path to a better life. Document review of the relevant legal documents that prescribes placement of migrant children and description of some experience from social work practice are made. Protection of migrant children is provided by accommodation for them, psychosocial support and appointment of guardians for unnacompanied children. Migrant children in Croatia are located in Refugee shelters for asylum seekers and in residential institutions for children and youths. This care system does not represent the best form of care for unnacompanied children because it can´t answer their needs as particularly vulnerable children. Problems in providing protecion for migrant children, especially problems with accommodation are also described in this paper.
