People who have not applied to the EU Settlement Scheme but have applied for and are granted British citizenship will have the right of abode in the UK. If they were lawfully resident in the UK under EU law as an EEA citizen at the end of the transition period, they will continue to enjoy relevant rights under the Citizens’ Rights Agreements even if they did not obtain EU Settlement Scheme status before they were granted British citizenship.
Those who have not been granted British citizenship and have not applied to the EU Settlement Scheme by 30 June 2021 will not have the right to remain in the UK after that date. If there are reasonable grounds for the person missing the deadline to apply to the scheme, they will be given a further opportunity to apply.
A person who has applied for and not yet received British citizenship can ensure they are in the UK lawfully after 30 June 2021 by making a free of charge application to the EU Settlement Scheme by that date.
