IMMIGRATION
Article 4 of the Immigration (Control of Entry through Republic of Ireland) Order 1972 provides, inter alia, that certain persons who are not patrial and who enter the United Kingdom from the Republic of Ireland after coming from a place outside the common travel area or after leaving the United Kingdom while having a limited leave to enter or remain there which has since expired are prohibited from taking up employment or any occupation for reward, except where they are nationals of states who are members of the European Economic Community. This Order amends Article 4 so as to provide that nationals of Greece (which becomes a member of the Community on 1st January 1981) who enter the United Kingdom in these circumstances are prohibited from taking up employment but not from taking up an occupation for reward.
