Is the Commission in possession of any research into the legal status of European immigrants in Switzerland?  Does the Commission consider it possible or desirable for relations between the EU and Switzerland to continue and to be deepened (particularly in the context of the European Economic Area) if the latter country fails to implement the basic employment rules of the single market?"
