When the Brexit transition period ends on 31 December this year, the Government will start to roll out a new immigration system.
This means that EU citizens and their family members (who right now exercise rights to live and work in the UK under EU law) need to obtain permission to stay in the UK.
If you or any of your family are EU, EEA or Swiss nationals you will need to apply to the EU Settlement Scheme.
Any person who misses the deadline on 30 June 2021 and stays in the UK will be here unlawfully, with no right to work or access public funds.
