Auslandschweizer registration framework (ASG SR 195.1 Art 11; Auslandschweizerregister)

The Auslandschweizerregister is legally defined as the information system E-VERA ('Vernetzte Verwaltung der Auslandschweizerinnen und -schweizer') of the EDA together with the corresponding paper files (ASG Art 3(b)). It is a CENTRAL federal register, not 26 cantonal registers — a structural distinction from the cantonal/communal Buergerrecht layers that govern naturalisation. Data handling: deletion-and-destruction of data is regulated in the implementing provisions (ASG Art 14(2)); statistical evaluation of register data is authorised under ASG Art 65 (in conjunction with the federal data-protection and statistics framework), which is the legal basis on which the EDA/BFS publishes the annual Auslandschweizerstatistik. Interfaces: Swiss residents' communes (Einwohnergemeinden) report every emigration abroad to the EDA (ASG Art 12(4)) and every return to Switzerland (ASG Art 13(3)), keeping the register synchronised with domestic civil-status movements; the representations carry out civil-status tasks abroad in cooperation with the Federal Office of Justice and enter the resulting changes in the register (ASG Art 53(2)). The documentation a registrant supplies (identity, nationality proof, address) is administrative; no apostille/legalisation regime is imposed by the ASG itself for the register entry (that arises, if at all, in the underlying civil-status or naturalisation processes, not in OPSC-01).
