The requirements for a temporary or occasional provision of tourism services by foreign providers from another EU Member State are significantly easier to accomplish than when offered on a permanent basis. For a temporary or occasional provision of tourism services, it is only necessary to prove that the tourism service provider is established in another Member State in accordance with the regulations of that State for performing the same regulated profession and by providing evidence of his or her formal qualifications under the condition that the Member State involved has recognised such qualifications 67 .
