From the end of July, anyone planning to enter Ireland will have to fill out a passenger locator form and some will have to isolate themselves upon arrival for 14 days (including Irish citizens and residents). There are exceptions for transport workers and passengers from Northern Ireland, and people travelling to Northern Ireland must fill out only part of the form.  The agreement, the culmination of more than two years of work between the two governments, means that the rights of citizens of both countries will be protected after Brexit, while ensuring that Ireland continues to meet its obligations under EU law. The agreement came into force on 31 January 2020, when the UK effectively left the European Union. This publication is available for www.gov.uk/government/publications/common-travel-area-guidance/common-travel-area-guidance nationals of all countries require a country transit visa, unless they have a valid Irish biometric visa, bc or BC BIVS valid and travel to the Republic of Ireland. Therefore, an Irish biometric visa holder does not need a separate visa from the UK when crossing the British border en route to Ireland. The Common Travel Area (CTA) is an agreement between the United Kingdom (UK) and Ireland, which gives the citizens of these countries a large number of rights. It implies more than the fundamental right to travel freely between the two countries. If you are an Irish citizen and you have the rights under the CTA agreements, you do not need to be authorised by border crossers to go to work in the UK, but you can apply for permission if you wish. If you are an Irish citizen living in the UK or a British citizen living in Ireland, you can travel freely within the CTA as part of the Common Travel Area (CTA). In 2011, the first public agreement between the British and Irish governments on the continuation of the CTA was reached. It was officially signed on 20 December 2011 in Dublin by uk Immigration Minister Damian Green and Irish Justice Minister Alan Shatter.
 At the same time, the two ministers also signed an unpublished Memorandum of Understanding.  Other nationalities travelling within the CTA remain subject to national immigration provisions. You need to check if you need a British or An Irish person who is subject to the visa requirement and you are travelling from Ireland to the UK. Reciprocal visa regime: An Anglo-Irish visa system has been applied to Chinese visitors since 20 October 2014 and to Indian visitors since 9 February 2015. This system allows visitors from these countries to move freely within the common travel area (in this case Ireland and Great Britain, but not to the Channel Islands and the Isle of Man) using either an Irish visa or a British visa. The practical result is that all persons arriving by plane from the UK are subject to immigration checks in Ireland.
