1.As regards the admission of a third-country national under this Directive, the applicant shall:
(a)present a valid travel document, as determined by national law, and, if required, an application for a visa or a valid visa or, where applicable, a valid residence permit or a valid long-stay visa; Member States may require the period of validity of the travel document to cover at least the duration of the planned stay;
(b)if the third-country national is a minor under the national law of the Member State concerned, present a parental authorisation or an equivalent document for the planned stay;
(c)present evidence that the third-country national has or, if provided for in national law, has applied for sickness insurance for all risks normally covered for nationals of the Member State concerned; the insurance shall be valid for the duration of the planned stay;
(d)provide evidence, if the Member State so requires, that the fee for handling the application provided for in Article 36 has been paid;
(e)provide the evidence requested by the Member State concerned that during the planned stay the third-country national will have sufficient resources to cover subsistence costs without having recourse to the Member State's social assistance system, and return travel costs. The assessment of the sufficient resources shall be based on an individual examination of the case and shall take into account resources that derive, inter alia, from a grant, a scholarship or a fellowship, a valid work contract or a binding job offer or a financial undertaking by a pupil exchange scheme organisation, an entity hosting trainees, a voluntary service scheme organisation, a host family or an organisation mediating au pairs.
2.Member States may require the applicant to provide the address of the third-country national concerned in their territory.
Where the national law of a Member State requires an address to be provided at the time of application and the third-country national concerned does not yet know the future address, Member States shall accept a temporary address. In such a case, the third-country national shall provide his or her permanent address at the latest at the time of the issuance of an authorisation pursuant to Article 17.
3.Member States may indicate a reference amount which they regard as constituting ‘sufficient resources’ as referred to under point (e) of paragraph (1). The assessment of the sufficient resources shall be based on an individual examination of the case.
4.The application shall be submitted and examined either when the third-country national concerned is residing outside the territory of the Member State to which the third-country national wishes to be admitted or when the third-country national is already residing in that Member State as holder of a valid residence permit or long-stay visa.
By way of derogation, a Member State may accept, in accordance with its national law, an application submitted when the third-country national concerned is not in possession of a valid residence permit or long-stay visa but is legally present in its territory.
5.Member States shall determine whether applications are to be submitted by the third-country national, by the host entity, or by either of the two.
6.Third-country nationals who are considered to pose a threat to public policy, public security or public health shall not be admitted.
