The single permit is open to all third-country nationals. Remunerated employment requires a temporary residence and work permit from the CRMD department. Some categories of workers are excluded from the procedure for an entry permit, since they can enter with an entry visa. The documents must be officially translated and certified. Biometric data are required. There is no maximum duration of stay for certain categories of workers (e.g. in the farming and agricultural sector or athletes and coaches). Special provisions exist for athletes and coaches, pub workers, priests and trainee accountants.
