The Dublin Regulation is a European Union law that determines which member state is responsible for processing an asylum seeker's application. It aims to prevent multiple applications in different countries and ensures that each asylum seeker is only processed in one EU country. Typically, the first country where the asylum seeker arrives is responsible for their claim. Under the Dublin Regulation, if an asylum seeker travels to another EU country after applying, they can be returned to the original country of entry. This regulation is part of the broader Common European Asylum System designed to create a fair and efficient asylum process across the EU.
