residence in member states they have maintained an uninterrupted five-year period of legal residence. This residency cannot be subject to any conditions, and is lost only by two successive years absence from the host nation. Family members of EU residents, in general, also acquire the same freedom of travel rights as the resident they accompany, though they may be subject to a short-stay visa requirement. Furthermore, no EU citizen may be declared permanently persona non grata within the European Union, or permanently excluded from entry by any member state. Workers Freedom of movement for workers is a policy chapter of the acquis communautaire of the European Union. It is part of the free movement of persons and one of the four economic freedoms: free movement of goods, services, labour and capital. Article 45 TFEU (ex 39 and 48) states that: Freedom of movement for workers shall be secured within the Community. Such freedom of movement shall entail the abolition of any discrimination based on nationality between workers of the Member States as regards employment, remuneration and other conditions of work and employment. It shall entail the right, subject to limitations justified on grounds of public policy, public security or public health: (a) to accept offers of employment actually made; (b) to move freely within the territory of Member States for this purpose; (c) to stay in a Member State for the purpose of employment in accordance with the provisions governing the employment of nationals of that State laid down by law, regulation or administrative action; (d) to remain in the territory of a Member State after having been employed in that State, subject to conditions which shall be embodied in implementing regulations to be drawn up by the Commission. The provisions of this article shall not apply to employment in the public service. Schengen Area A different arrangement amongst 26 European countries, covers some but not all European Union member states together with some non-member states. The arrangement allows visa-free travel between the countries in this area, in general without border controls. A foreign national who holds a visa issued by any of these countries can travel freely within the area. Mercosur The Mercosur alliance between Argentina, Brazil, Paraguay and Uruguay includes a freedom of movement area between its member states and five other associate states. Citizens don't require a passport to travel through other Mercosur or associate countries. Australia
