1. Entry: travel restrictions, border controls and quarantine
Germany introduced travel restrictions for entries from outside the Schengen area on 17 March 2020. They were last prolonged on 14 May 2020, based on an EU recommendation and are currently expected to be in place until 1 July. All corresponding entries from non-EU-citizens and citizens of non-Schengen states by plane or ship will be affected. Entry will be possible for German citizens.
