The Visa Information System (VIS) (english)

The Visa Information System (VIS) allows Schengen States to exchange visa data and is jointly operated by the Schengen states, which also include Switzerland. Everyone has the right to obtain confirmation as to whether data is processed about them in the VIS and, where applicable, has the option of accessing this information and having it corrected or deleted, if they are entered incorrectly or unlawfully. Sample letters and further information are available on the website of the Federal Data Protection and Information Commissioner.
