http://www.ukba.homeoffice.gov.uk/britishcitizenship/eligibility/naturalisation/standardrequirements/ - the title of the page is "Standard requirements for naturalisation" - apologies, but I wasn't able to find any other page that would explain the requirements for naturalisation for EEU nationals.
The only other thing on this site that could have any effect (which I find simply contradicting what is stated in the subsequent section about EEU nationals) is the following:
Residential requirements
To demonstrate the residential requirements for naturalisation, you must have:
- been resident in the UK for at least five years (this is known as the residential qualifying period); and
- been present in the UK five years before the date of your application; and
- not spent more than 450 days outside the UK during the five-year period; and
- not spent more than 90 days outside the UK in the last 12 months of the five-year period; and
- not been in breach of the Immigration Rules at any stage during the five-year period.
On one hand as EEU citizen I get and keep the permanent residence status if I don't leave UK for more than 2 years and after having held it for 12 months I can apply for naturalisation. On the other hand there are only 5 years for non-EEU people.
The confusing thing here is that if I was a non-EEU national, the naturalisation point and 5-year residential requirements are effectively the same and I could already be applying for naturalisation. However, as EEU I effectively need 6 years not 5. The rules are almost contradicting each other and I thought you fall under one section OR the other, not both.
However, even assuming that this section applied to me, the only item that is questionable in my case would be
not spent more than 450 days outside the UK during the five-year period. If UKBA started calculating 5 years (instead of "holding residence status for 12 months") at the point of naturalisation the period I could be away would would be reduced from 2 years to 450 days. But if I left only for 12 months, and then stayed another 12 months (to fulfill 4th bullet point) I think I should still be good. What would be insane would be if that meant that I had to then stay yet another year to get to 6years (as EEU citizen).
If you don't want to explain this again and wouldn't mind pointing me to another thread where you explained a similar case already I'm perfectly happy to read that instead.
