The Committee on the Elimination of Racial Discrimination adopted a General Recommendation on the issue of discrimination against non-citizens as a means to raise awareness on the situation of these vulnerable groups to find solutions to the daily problems that they are faced with. General Recommendation Number 30 asks States parties, among other things, to review their national legislation to ensure that it guarantees against racial discrimination applied to non-citizens and to pay greater attention to the issue of multiple discrimination faced by non-citizens, in particular concerning the children and spouses of non-citizen workers.
