As the UK continues to adapt to life post-Brexit, the next important date from an immigration standpoint is 30 June 2021.
European Economic Area (EEA) and Swiss nationals who were resident in the UK on or before 31 December 2020 have until this date to submit their initial applications under the EU Settlement Scheme. If they do not, they will no longer have permission to remain in the UK and will have to make arrangements to leave.
