Es geht nicht, hier das offizielle Statement falls noch mehr davon betroffen sind:
Please note we spoke to both the Customs Officers on Duty (LG initials) and Supervisor (initials AB) at KFXE Customs and they have confirmed that unfortunately the German and Portuguese passengers will not be allowed to clear if they return tomorrow evening from Bahamas.
I explained to them that they had already cleared in US since last week and this is just a day trip but this apparently does not qualify as an exemption: because they are of Schengen nationality and not Residents they will be banned from re-entering.
