This handbook provides an overview of the law applicable to asylum, border man-agement and immigration in relation to European Union (EU) law and the European Convention on Human Rights (ECHR). It looks at the situation of those foreigners to whom the EU usually refers as third-country nationals, although that distinction is not relevant to cited ECHR law. This handbook is designed to assist legal practitioners who are not specialised in the field of asylum, borders and immigration law; it is intended for lawyers, judges, prosecutors, border guards, immigration officials and others working with national authorities, as well as non-governmental organisations (NGOs) and other bodies that may be confronted with legal questions relating to these subjects.
