1.Where the authorisation for the purpose of research or studies is issued by the competent authorities of a Member State not applying the Schengen acquis in full and the researcher or student crosses an external border to enter a second Member State in the framework of mobility, the competent authorities of the second Member State shall be entitled to require as evidence of the mobility the valid authorisation issued by the first Member State and:
(a)a copy of the notification in accordance with Article 28(2) or Article 31(2), or
(b)where the second Member State allows mobility without notification, evidence that the student carries out part of the studies in the second Member State in the framework of a Union or multilateral programme that comprises mobility measures or an agreement between two or more higher education institutions, or for researchers, either a copy of the hosting agreement specifying the details of the mobility of the researcher or, where the details of the mobility are not specified in the hosting agreement, a letter from the research organisation in the second Member State that specifies at least the duration of the intra-EU mobility and the location of the research organisation in the second Member State.
In the case of the family members of the researcher, the competent authorities of the second Member State shall be entitled to require as evidence of the mobility the valid authorisation issued by the first Member State and a copy of the notification in accordance with Article 30(2) or evidence that they are accompanying the researcher.
2.Where the competent authorities of the first Member State withdraw the authorisation, they shall inform the authorities of the second Member State immediately, where applicable.
3.The second Member State may require to be informed by the host entity of the second Member State or the researcher or the student of any modification which affects the conditions on which basis the mobility was allowed to take place.

(b)the first Member State shall, upon request of the second Member State, allow re-entry of the researcher and, where applicable, of his or her family members or of the student without formalities and without delay. This shall also apply if the authorisation issued by the first Member State has expired or has been withdrawn during the period of mobility within the second Member State.
