As an EU citizen who's lived in the UK for 8 years, I am considering applying for British citizenship.
My birth country currently allows dual citizenship, but is considering outlawing this. While this is unlikely to happen, I do wonder what would happen if they did.
Could I lose my birth country's citizenship if I legally acquired dual citizenship before this was outlawed? And is there any precedent for this?
As a bonus/follow-up question, which is more country specific: If at some point in the future I had to choose between the two nationalities, I'd be inclined to keep my birth country's citizenship (as I would rather not lose the rights that come with a EU passport). However, if I lost my UK passport I'd probably be residing in the UK illegally - as I would never have obtained the necessary documentation EU nationals without a UK passport will need to stay in the UK post-brexit.
Is there any precedent for people losing their citizenship for the country in which they reside, and what would their options be if that happened?
