In accordance with the presumption as regards fulfilment of conditions of duration of stay laid down in , the fulfilment of entry conditions and the authorisation of entry are expressed in an entry stamp in a travel document. The absence of such entry stamp or the absence of a travel document might therefore be considered as an indication that the holder does not fulfil the entry conditions. With the start of the operation of the Entry/Exit System established by of the European Parliament and of the Council (10) (EES) leading to substitution of the stamps with an entry in the , that presumption will become more reliable. Member States should therefore carry out the screening of third-country nationals who are already within their territory and who are unable to prove that they fulfilled the conditions of entry into the territory of the Member States. The screening of such third-country nationals is necessary in order to compensate for the fact that they presumably managed to evade entry checks upon arrival in the Schengen area and therefore could have not been either refused entry or referred to the appropriate procedure following the screening. Carrying out the screening could also help in ascertaining, through the consultation of the databases referred to in this Regulation, that the persons concerned do not pose a threat to internal security. By the end of the screening within the territory, the third-country nationals concerned should be subject to a return procedure or, where they apply for international protection, to the appropriate asylum procedure. Third-country nationals should not be subjected to repeated screenings.

Regulation (EU) 2017/2226 of the European Parliament and of the Council of 30 November 2017 establishing an Entry/Exit System (EES) to register entry and exit data and refusal of entry data of third-country nationals crossing the external borders of the Member States and determining the conditions for access to the EES for law enforcement purposes, and amending the Convention implementing the Schengen Agreement and Regulations (EC) No 767/2008 and (EU) No 1077/2011 (OJ L 327, 9.12.2017, p. 20). ↩︎
