Freedom of movement in the context of "Immigration law"

An economic union is a type of trade bloc which is composed of a common market with a customs union. The participant countries have both common policies on product regulation, freedom of movement of goods, services and the factors of production (capital and labour) as well as a common external trade policy. When an economic union involves unifying currency, it becomes an economic and monetary union.

The purposes for establishing an economic union normally include increasing economic efficiency and establishing closer political and cultural ties between the member countries.

A single market, sometimes called common market or internal market, is a type of trade bloc in which most trade barriers have been removed (for goods) with some common policies on product regulation, and freedom of movement of the factors of production (capital and labour) and of enterprise and services. The goal is that the movement of capital, labour, goods, and services between the members is as easy as within them. The physical (borders), technical (standards) and fiscal (taxes) barriers among the member states are removed to the maximum extent possible. These barriers obstruct the freedom of movement of the four factors of production (goods, capital, services, workers).

A common market is usually referred to as the first stage towards the creation of a single market. It usually is built upon a free trade area with no tariffs for goods and relatively free movement of capital, workers and services, but not so advanced in reduction of other trade barriers.

An open border is a border that enables free movement of people and often of goods between jurisdictions with no restrictions on movement and is lacking a border control. A border may be an open border due to intentional legislation allowing free movement of people across the border (de jure), or a border may be an open border due to a lack of legal controls, a lack of adequate enforcement or adequate supervision of the border (de facto). An example of the former is the Schengen Agreement between most members of the European Economic Area (EFTA and the EU). An example of the latter has been the border between Bangladesh and India, which is becoming controlled. The term "open borders" applies only to the flow of people, not the flow of goods and services, and only to borders between political jurisdictions, not to mere boundaries of privately owned property.

Open borders are the norm for borders between subdivisions within the boundaries of sovereign states, though some countries do maintain internal border controls (for example between the People's Republic of China mainland and the special administrative regions of Hong Kong and Macau, between the United States and the unincorporated territories of Guam, the Northern Mariana Islands and American Samoa, and the Minor Outlying Islands, or between North Korea's provinces and cities). Open borders are also usual between member states of federations, though (very rarely) movement between member states may be controlled in exceptional circumstances. Federations, confederations and similar multi-national unions typically maintain external border controls through a collective border control system, though they sometimes have open borders with other non-member states through special international agreements – such as between Schengen Agreement countries as mentioned above.

A border checkpoint is a location on an international border where travelers or goods are inspected and allowed (or denied) passage through. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings (e.g. the Schengen Agreement). Land border checkpoints (land ports of entry) can be contrasted with the customs and immigration facilities at seaports, international airports, and other ports of entry.

Civil and political rights are a class of rights that protect individuals' freedom from infringement by governments, social organizations, and private individuals. They ensure one's entitlement to participate in the civil and political life of society and the state.

Civil rights generally include ensuring peoples' physical and mental integrity, life, and safety, protection from discrimination, the right to privacy, the freedom of thought, speech, religion, press, assembly, and movement.

The visa policy of Ireland is set by the Government of Ireland and determines visa requirements for foreign citizens. If someone other than a European Union, EFTA or Common Travel Area citizen seeks entry to Ireland, they must be a national of a visa-exempt country or have a valid Irish visa issued by one of the Irish diplomatic missions around the world.

Although Ireland is a member of the European Union, it is not part of the Schengen Area and therefore sets its own visa policy. Ireland also operates the Common Travel Area with the United Kingdom, the Channel Islands and the Isle of Man which specifies open borders between the countries and territories. Established in 1923, it permits British and Irish citizens freedom of movement around the Common Travel Area and to cross its borders with minimal or no identity documents.

A police state is a state whose government institutions exercise an extreme level of control over civil society and liberties. There is typically little to no distinction between the law and the exercise of political power by the executive, and the deployment of internal security and police forces play a heightened role in governance. A police state is a characteristic of authoritarian, totalitarian or illiberal regimes (contrary to a liberal democratic regime). Such governments are not exclusive to simply one-party states or dominant-party states, as they can also arise in a democracy or multi-party system.

Originally, a police state was a state regulated by a civil administration, but since the beginning of the 20th century it has "taken on an emotional and derogatory meaning" by describing an undesirable state of living characterized by the overbearing presence of civil authorities. The inhabitants of a police state may experience restrictions on their mobility, or on their freedom to express or communicate political or other views, which are subject to police monitoring or enforcement. Political control may be exerted by means of a secret police force that operates outside the boundaries normally imposed by a constitutional state. Robert von Mohl, who first introduced the rule of law to German jurisprudence, contrasted the Rechtsstaat ("legal" or "constitutional" state) with the anti-aristocratic Polizeistaat ("police state").

The European Union citizenship is a legal status afforded to all nationals of member states of the European Union (EU). It was formally created with the adoption of the 1992 Maastricht Treaty, at the same time as the creation of the EU. EU citizenship is additional to, as it does not replace, national citizenship. It affords EU citizens with rights, freedoms and legal protections available under EU law.

EU citizens have freedom of movement, and the freedom of settlement and employment across the EU. They are free to trade and transport goods, services and capital through EU state borders, with no restrictions on capital movements or fees. EU citizens have the right to vote and run as a candidate in certain (often local) elections in the member state where they live that is not their state of origin, while also voting for EU elections and participating in a European Citizens' Initiative (ECI).
