Form S1
The S1 form certifies entitlement to health insurance, allowing registration with the institution in the country of residence when the insured is covered by another country. For certain cross-border workers affiliated in Luxembourg, exchanges also occur electronically, notably with the S072 document.
The S1 does not replace a work permit or the A1 certificate related to applicable social legislation. Check with the CNS and your local fund to ensure registration has been completed. The process varies depending on the country of residence; merely holding a Luxembourg social security card does not resolve all local procedures.
