On the FOSDEM FAQ[1], it says "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." One of the projects I'm involved with did that, providing an invitation letter for a developer from India and another developer from China and also arranging their travel and accommodation costs. The developer in India just got a call from the Belgian embassy asking for a second letter from FOSDEM organizers. He has previously had a Schengen visa (from an event in Germany last year) and his travel agent had told him that renewing the visa was just a formality so he already has flight and hotel bookings and he is quite keen to get this sorted out quickly. Can anybody from FOSDEM assist with these requests from the Belgian officials? Given that FOSDEM is a free event and that people don't normally register to attend, would the FOSDEM team consider providing a self-service web-form for guests like this who do need to "register" and obtain their invitation letters on demand? Note that another organization is making the financial sponsorship arrangements, this is not a request for FOSDEM to provide money or guarantees. Regards, Daniel 1. https://fosdem.org/2016/faq/
