Strangers into Citizens was a political advocacy campaign from around February 2007 to May 2010 by the then Citizen Organising Foundation, also known as the London Citizens organisation, now defunct, having been merged into the Citizens UK organisation as separate local chapters. The campaign called for irregular and extraordinary (one-off and one-time-only) general amnesty, regularisation, naturalisation, and British citizenship for illegal immigrants in the United Kingdom. The campaign became defunct in 2013.
