Irish citizens have a different status to other non-British EU citizens. For example, under the Common Travel Area arrangements, British and Irish citizens move freely and reside in either jurisdiction and enjoy associated rights and entitlements. If you’re an Irish citizen, the Government of Ireland has information about what Brexit means for you. You can also sign up to Irish government’s weekly Brexit update.
If you are a non-British or Irish EU citizen living in Greater Manchester, you need to check what you need to do to continue to live in the UK after Brexit.
If you don’t have "indefinite leave to remain"/ "indefinite leave to enter" status from the UK government, and you want to remain in the UK after 31 December 2020, you need to take action now and apply to the EU Settlement scheme.
