The main issues on which the positions of the two institutions still differ are the question of an additional document to be issued together with the single permit, the transfer of pension rights and the obligation for member states to provide correlation tables to the Commission.
Peamised küsimused, mille osas kahe institutsiooni seisukohad veel erinevad, on ühtse loaga koos esitatav täiendav dokument, pensioniõiguste ülekandmine ning liikmesriikide kohustus esitada komisjonile vastavustabelid.
