Visiting and videos

Q: I need a formal invitation for a VISA request

For legal reasons, the FOSDEM organization can only issue such letters of invitation to “main track” speakers for whom we also make travel and hotel arrangements.

If you are attending FOSDEM as part of your involvement with a project represented at our conference, we recommend you get in touch with someone you know locally who is involved in the project and ask them to invite you.

For information regarding Belgian visa requirements, we refer you to Belgium’s Foreign Affairs, Foreign Trade and Development Cooperation website.
