Switzerland has firewalls between immigration enforcement and service providers to guarantee access to basic services to all, including undocumented migrants. This right is based on the Swiss Federal Constitution and regulated by the Public Health Insurance Law.

Switzerland is among one of a few European countries in which undocumented migrants have the right to access healthcare services beyond emergency healthcare (i.e. life-threatening situations or situations that pose a serious risk to health). According to the Public Health Insurance Law, every person living in Switzerland longer than 3 months and not having health insurance in another country has the right and the duty to take out ‘basic health insurance’ (Grundversicherung). This right and obligation also applies to undocumented migrants. Persons living in a modest economic situation may apply for subsidies to pay for the insurance premiums. Health insurers as well as health providers may not report any personal data of undocumented clients to a third party, except for information required by the insurance for purely administrative purposes.
