Under Directive 2004/38/EC, the Citizens’ Directive, nationals of the European Economic Area (EEA), which comprises the EU Member States, Norway, Iceland and Lichtenstein, benefit from EU free movement law. Throughout this Practice Note, the term 'EU citizens' which refers to EU Member States' nationals also includes EEA nationals. The Citizens’ Directive creates two additional categories of family members of EU nationals who are exercising treaty rights in another Member State. These are family members who do not meet the definition of direct ‘family members’, and are: • in a ‘durable relationship’ with an EU national, which is ‘duly attested’, or • ‘other family members’, who: ◦ were dependants or members of the household of the EU national prior to the EU national's coming to the host Member State, or ◦ have serious health grounds which strictly require their personal care by the EU national See Practice Note: Family members of EU nationals—definitions and rights of entry and residence
