The UK government has reached an agreement with the European Union on citizens’ rights in negotiations on the UK’s withdrawal from the EU. This will provide certainty about the future to millions of EU citizens and their families in the UK. Most importantly, it will allow you to stay here after we leave the EU on 29 March 2019, and to continue to access public funds and services.
The UK government has agreed that EU citizens and their families arriving during the implementation period, from 30 March 2019 to 31 December 2020, will be able to stay on the same terms but will need to register if they choose to stay for longer than 3 months.
There is no need for EU citizens living in the UK to do anything now. There will be no change to the status of EU citizens living in the UK while the UK remains in the EU. If you would like to find out the latest information you can sign up for email updates from the UK Home Office.
There is also a very useful page that provides information for British Immigrants living in the other EU countries.
