Protecting children is paramount for upholding the European values of respect for human rights, dignity and solidarity. It is also about enforcing European Union law and respecting the Charter of Fundamental Rights of the European Union and international human rights law on the rights of the child. The existing EU legislation provides a framework for the protection of the rights of the child in migration, including reception conditions, dealing with their applications and integration. This article elaborates on provisions concerning the international protection system for minor migrants. It examines entry strategies put into place by young migrants facing the Spanish migration system. The first part examines the guidelines of the reception system for unaccompanied migrant minors arriving in Spain. An assessment of the Spanish arrangements for the reception of umms is carried out in the second part, focussing on three key aspects: refoulement at the border (pushback), age determination and guardianship.
