This ad hoc query explores the tailored measures implemented to enhance the involvement of newly arrived third-country nationals (TCNs) in the host society, in particular, the fields these measures cover, the level at which they take place, whether TCNs who are already more permanently settled can participate, and whether nationals can volunteer to support their implementation. It also examines whether these measures are compulsory for TCNs to validate their integration path, and what the consequences are in the event of non-compliance, notably regarding the right of residence.
