The European Union has formally adopted a work authorization program intended to attract highly skilled foreign workers and modeled after the United States’ Green Card program. The “Blue Card” will allow immigrants to work in any EU member state (except Great Britain, Ireland and Denmark) and will entitle card holders to limited social and welfare rights, for a renewable period of one to four years, EUobserver.com reported. Blue Card holders will receive equal treatment with nationals as to working conditions, including pay and dismissal, and will have some ability to move between EU member states. The program also includes penalties for employers who hire illegal immigrants.
