Under the Common Travel Area (CTA), Irish and British citizens move freely and live in one of the two jurisdictions and enjoy the rights and rights associated with them, including access to employment, health care, education, social benefits and the right to vote in certain elections. After the war, the Irish resumed their previous provisions, which allow free movement, but the British opposed it until a “similar immigration policy” was agreed in both countries. As a result, the British maintained immigration controls between the islands of Ireland and Great Britain until 1952, much to the dismay of the Unionist population in Northern Ireland.  Prior to the creation of the Land of Bavaria, British immigration legislation in Ireland was considered part of the United Kingdom. With Ireland`s independence in 1922, the British Home Office was not inclined to introduce passport and immigration controls between Ireland and Northern Ireland, which would have meant patrolling a porous and outdated land border of 499 km. However, if the situation were to continue before 1922, the Irish immigration authorities would have to continue to apply British immigration policy after independence. The Irish Ministry of the Interior was sensitive to the continuation of the status quo and, in February 1923, an informal agreement was reached on this issue: each party would apply the other party`s immigration decisions and the Irish authorities would receive a copy of the British Code of Suspects (or “Black Book”) of non gratae for personal use in the United Kingdom.  Nationals of European Economic Area Member States who are not nationals of the United Kingdom and Ireland have the right, under EU law, to enter and stay freely in Ireland (and had the same right in the United Kingdom, whereas the Latter was a member of the EU). You must carry a valid travel document, passport or national identity card in order to enter the CTA and travel between Ireland and the United Kingdom.
 The authors recommended a comprehensive treaty on the common travel area, which transposed all the rights of Irish citizens to the United Kingdom (and vice versa) into international law. Otherwise, they said that bilateral agreements between the United Kingdom and Ireland on specific issues would be better than nothing. Since then, the two governments have agreed on a Memorandum of Understanding on the common travel area and a social security treaty. I hope this will ensure that there will be no practical problems for the Irish after Brexit. Reasons and objectives of the proposal The United Kingdom of Great Britain and Northern Ireland (“United Kingdom”) will withdraw from the European Union on 30 March 2019 (withdrawal date) and become a third country. Currently, British citizens are also EU citizens. They enjoy the fundamental right to move and stay freely […] We are aware that all the current rights that come from the common travel area do not reflect the free movement traffic of the EU that exists before Brexit… Although Clause 2 of the Act is welcomed insofar as it is intended to guarantee Irish citizens access and stay in the UK, the result is, on the whole, a restriction of certain existing EU rights… Under Irish law, all British citizens – including channel manx and Islanders who were not entitled to benefit from the European Union`s free movement provisions – are exempt from immigration control and are immune from deportation.  You have the right to live in Ireland without restrictions or conditions.  They have never been treated as foreigners under Irish law, with a few exceptions, since they were never subject to the Alien Act in 1935 or to any provision under that Act.
 British citizens can therefore move to Ireland to live, work or retire and, unlike other EU citizens, they are not required to provide sufficient funds or private health insurance to retire.
