Furthermore, visa requirements tend to affect people from less
privileged countries the most. If we're serious about diversity, I
think
that we should include covering the visa fee if we offer
travel+accommodation by default, and that this should be the default
for
DebConf going forward, and ideally for all Debian events.
I realise I have some bias here, I myself come from a country where I
need a visa nearly everywhere I want to travel to, but I do think that
including visa fees by default will help making Debian easier to
contribute to for people who come from such countries, and ultimately
have a small role in helping us expand to more areas and improve our
diversity.
