Right the proposed brexit May deal-So reading the bolded bit, Irish citizens will need to apply for settled status. That contradicts everything you have said in the last few pages. You clearly have no idea yourself what you are on about so it's unsurprising that no-one else has any idea either.
Once the UK leaves the EU, its only land border with the bloc will be the 310-mile line between Northern Ireland and the Republic of Ireland. Decisions need to be made about how to manage the movement of people and goods across that border.
The UK, Ireland and the EU have all committed to maintaining the Common Travel Area (CTA), which has been in place for most of the period since the establishment of the Irish Free State in 1922. The CTA allows free movement of British and Irish citizens between the UK, Ireland, the Channel Islands and the Isle of Man and provides access to various government services in each country.
Ireland will continue to allow freedom of movement for citizens of the other 26 EU member states. The UK envisages using inland controls, through the access to labour markets and social security, to enforce immigration policy without requiring checks on people crossing the Irish border.
