A short-stay Type C – Business Visa is required for travel to Belgium for business purposes.
This is only for visits of less than 90 days.
Is the application process different from application for a tourist visa?
No. The costs, conditions, and processes for both a business and a tourist visa in Belgium are similar.
The key distinction between the two is that you must provide one of the following for a business visa:
An invitation letter from a Belgian organization requesting your presence, or a letter from your boss outlining the purpose of your trip.
