I’m in the same situation as the original poster. I sent my documents on 28 Feb via signed delivery, and I got confirmation that they arrived in Peterborough on the 1st of March. So far, there’s no update in the system.
I’m an EU citizen with settled status who naturalised in February (with no effect on my other citizenship). Does anyone know if it’s still legal to travel using my EU identity card + settled status? Obviously I can enter the EU, but will I have difficulties at the UK border? I know ID cards are allowed for those with status for another few years, but I’m not sure if naturalisation “voids” settled status. If I try to enter the UK using my ID card, I’ll have to see a border agent. If they ask where is my passport and I tell them it’s with the UK Passport Office, I don’t want to get in trouble. Thanks for any help / advice!
