Please note that you do NOT need a letter of invitation from the trade fair company to apply for a Schengen visa at the German Embassy/Consulate. This rule has changed since September 2013 and was adopted by the Federal Government.
For a person travelling to the fair as a visitor, you should submit the following information:
1) Visitor admission eTicket, which can be purchased online.
In addition, please contact the German embassy/consulate from which you will apply for the Schengen visa or visit their official website to find out which other documents you also need to submit in person.
If you have any further questions regarding your visa matters, it is best to contact our colleagues in your country. Worldwide, 77 partners represent Messe Düsseldorf in 141 nations. They offer a wide range of services for visitors, exhibitors and the press. You can find more information about our foreign representatives and their contact details here.
