The Prime Minister has been clear that safeguarding the rights of EU citizens and citizens of the EFTA states already living in the UK is a priority for negotiations, as set out in the Withdrawal Agreement.
It will allow EU citizens living in the UK before the end of the implementation period to continue living their lives broadly as they do now. We are also in discussions with the EEA EFTA states (Norway, Iceland and Liechtenstein) and Switzerland on agreements to protect the rights of UK nationals living in those countries and their nationals living in the UK.
Au pairs from the EU arriving after the end of the implementation period will need to apply under the future immigration arrangements. The Home Office will set out further details about these arrangements in due course.
