I am in Germany on a tourist/visitor/business visa. For important reasons, I want to stay in Germany past the expiry date of my visa.
Can I have my visa extended in Germany?
It is only possible to extend the validity of visas in certain exceptional cases. This can only be done by the foreigners authority in Germany covering the place of residence of the visa holder. This is the only authority that can decide on an extension of a visa during a visit to Germany. Neither the Federal Foreign Office nor its missions abroad can do so.
