Special Rapporteurs often conduct fact-finding missions to countries to investigate allegations of human rights violations. They can only visit countries that have agreed to invite them.

Aside from fact-finding missions, Rapporteurs regularly assess and verify complaints from alleged victims of human rights violations. Once a complaint is verified as legitimate, an urgent letter or appeal is sent to the government that has allegedly committed the violation. If no complaint has been made, Rapporteurs may intervene on behalf of individuals and groups of people of their own accord.
