With the UK not yet having triggered Article 50, and there being enough potential issues (legal and political) that it looks like nothing may happen before the Autumn at the earliest, most likely it'll be quite some time until rules on EU citizens already living in the UK become clear. Understandably, that's causing worry here and elsewhere due to the uncertainty, many of my EU friends included!
While we wait for news of any new rules, what about the existing ones?
Firstly, UK citizenship and passport - how long would an EU citizen have to have been living and working in the UK to be able to apply, and what's the process they'd need to follow?
Otherwise, for EU citizens who've been living and working in the UK for a number of years, who don't want to get a UK passport (eg because they'd then have to give up their other one), are there any other permanent statuses they could get to safeguard / cement their rights to live in the UK? And if so, what and how?
