> But EU citizens working in the UK must apply for pre-settled status by the 30 June 2021.

I just want to point out that this also applies to EU citizens who already have a certificate for permanent residence. That's right - if you went through the painstaking and expensive process of applying for a document on which the UK government states that you have the right to live and work in the UK indefinitely... that document is now worth nothing and you have to apply for "settled status" just like anyone who doesn't have that certificate.
