The simple way to get a visa – no need for invitation letters.
In July 2013 a decree was issued by the German Ministry of Foreign Affairs that an invitation letter by the trade show organizer is as a rule no longer needed when applying for visa in order to attend a trade show in Germany. All Visa Centers as well as German Embassies and Consulates were informed about this decree http://www.auma.de/en/.
Moreover visa fees are waived for exhibitors at German trade fairs. Please refer in your visa application to this. If an embassy insists on a letter of invitation, please contact
Additional information regarding the visa application procedure, requirements for the issue and application forms in different languages are available at the website "visa regulations" of the German Foreign Office as well as at the respective websites of the embassies and consulates general.
Persons requiring a visa to enter Germany should submit their applications in good time prior to the respective trade show. A visa application is possible up to three months before entry.
