The general processing time for the Germany business visa is up to two weeks. However the time it will take you to get a business visa also depends on the workload of the German Embassy/Consulate you have submitted your application to.

Single entry – that permits you to enter Germany only once and spend the number of days stated in your visa, i.e. 10 days.

Multiple entries – which permits you to enter more than once in Germany in a given period i.e. 1 January till 1 May, with the sole condition that you do not overstay the number of permitted days

i.e. 20 days. You may also get a multiple entry visa with a validity of one year or more. In these cases, you should take care to not violate the 90-days per 6 months rule, according to which whenever you wish to make a trip to Germany, you just have to look back and count whether you have stayed in the Schengen Area more than 90 days within the last 180 days.

If you intend to stay in Germany for longer than your visa allows, you must submit an application along with a few visa extension paperwork. The procedure is straightforward and quick. You

may be subjected to a brief interview on the reasons for your application for a short-stay visa extension, during which you must persuade the interviewer that you require a Schengen visa renewal.
