Dinarte Pereira (21), pictured, works at the Talana Hotel on Longueville Road and lives in staff quarters.
It is believed that before he went missing Mr Pereira may have been visiting a girlfriend somewhere near Havre des Pas.
Police think his car, a five door white Ford Escort with the registration J44632, is in the area.
Mr Pereira has no relations in the Island, but any of his friends or anyone else who can help are asked to contact the Police.
