The mission abroad decides what type of visa to issue (period of validity, number of days covered) on the basis of the documents submitted. If necessary, it may issue a visa that entitles the holder to enter the Schengen area on multiple occasions within the given period of validity. Such annual or multi-annual visas, which are valid for one or more years, are as a rule only issued to persons who have already been to Germany or other Schengen states several times in the past and whom the mission abroad considers to be particularly trustworthy (e.g. because of their position in the host country). Please note that regardless of the length of validity, visas only entitle the holder to a maximum stay of 90 days in any period of 180 days.
