After the application for the ETIAS visa waiver has been submitted and the traveller has received the approved travel authorization, the European visa will be valid for a period of three consecutive years or until the passport expires.
Not only is the ETIAS valid for a 3-year period, but the traveller can use it for multiple short-term entries. The ETIAS grants visitors stays of up to 90 days in a 180 day period. When completing the application, the traveller will have to provide travel details and select the member country for their arrival.
Travellers must apply with a valid passport in order to obtain the ETIAS. In the case that the passport has expired, the ETIAS will no longer be valid. The person will have to enroll once again with the ETIAS system. Visitors from visa exempt countries will be expected to have a valid travel authorization upon arrival at a Schengen member country port of entry.
