Article 7
General rules for determining residence 1. For the purposes of this Directive, "normal residence" means the place where a person usually lives, that is for at least 185 days in each calendar year, because of personal and occupational ties, or, in the case of a person with no occupational ties because of personal ties which show close links between that person and the place where he is living. However, the normal residence of a person whose occupational ties are in a different place from his personal ties and who consequently lives in turn in different places situated in two or more Member States shall be regarded as being the place of his personal ties, provided that such person returns there regularly. This last condition need not be met where the person is living in a Member State in order to carry out a task of a definite duration. Attendance at a university or school shall not imply transfer of normal residence. 2. Individuals shall give proof of their place of normal residence by any appropriate means, such as their identity card or any other valid document. 3. Where the competent authorities of the Member State of importation have doubts as to the validity of a statement as to normal residence made in accordance with paragraph 2, or for the purpose of certain specific controls, they may request any additional information or evidence.
