In a No Deal scenario, the UK Government has indicated that EU citizens’ rights will be protected, but that there will be certain changes:
(a) they will have no right of appeal to the European Court of Justice
(b) the UK deportation threshold (which is more stringent than the EU equivalent) would replace the EU deportation threshold for any crimes committed after 29 March 2019; and
(c) there will be a new cut-off date of 29 March 2022 for non-EU family members to join EU citizens in the UK; thereafter they must apply through the applicable UK Immigration Rules.
