The No One is Illegal Network (Ingen människa är illegal in Swedish) works to provide practical support to people who are forced to live undocumented after having had their applications for asylum refused.
The No One is Illegal Network consists of local groups. The local groups are autonomous and activities may differ a bit but are all related to working practically and politically for the rights of undocumented migrants.
The No One is Illegal Network
There are local groups in Stockholm, Göteborg, Malmö and others places in Sweden. You can contact them all on their shared website.
