The Member States which apply the Schengen acquis in full and the Member States which do not yet apply the Schengen acquis in full but operate the EES shall introduce the EES at their internal borders with the Member States which do not yet apply the Schengen acquis in full and do not operate the EES.
Na Ballstáit a chuireann acquis Schengen i bhfeidhm ina iomláine agus na Ballstáit nach gcuireann acquis Schengen i bhfeidhm ina iomláine fós ach a oibríonn EES, tabharfaidh siad EES isteach ag a dteorainneacha inmheánacha leis na Ballstáit nach gcuireann acquis Schengen i bhfeidhm ina iomláine fós agus nach n-oibríonn EES.
