Asylum shopping is a term used mostly in the context of the European Union and the Schengen area to describe the practice by asylum seekers of applying for asylum in several member states or seeking to apply in a particular state after transiting other member states. Reasons for asylum-shopping behaviour may range from the legitimate (such as reunification with family already in the destination state or legal differences among states that would cause the individual to be recognized as a refugee in one state but not another) to the fraudulent (such as multiple applications filed in bad faith to obtain employment authorization or delay deportation). One of the objectives of Police and Judicial Co-operation in Criminal Matters is to prevent asylum shopping. The Dublin Convention stipulates that an asylum seeker is returned to the country where they first entered the Schengen area.
