Your meta description acts as organic ad text. What this means is that when your ad ranks for a keyword, Google and other engines will often show the meta description as a summary of the page. This makes the meta description as important as ad text.
You should keep in mind that your visa will not necessarily include a residence permit and/or work permit. A so-called Schengen visa usually allows you to stay in Germany and other states within the Schengen area for up to 90 days. However, a Schengen visa does not permit you to take up any paid jobs in Germany.
What the Schengen Visa Gives You. The Schengen visa allows a maximum of 90 days travel in Schengen countries you've applied to visit, for every 180 days period. It can be single or multiple entry. The day of your arrival and departure count as full days towards the 90.
