hi,
I got ILR as Settlement of spouse (marriage to UK woman) 2 years ago, however unfortunately we are now divorced, my questions:-
1) can i apply for UK citizenship?
2) what is the requirements?
3) when i will get the UK citizenship?

1) If you satisfy the standard requirements.
2) See 1).
3) Waiting times.

thanks vinny, one more question plz. i got a good job outside UK, can i leave UK and still my ILR will be valid? then i will return back as return resident and continue living in UK. can i do that and my ILR will still be valid?

An ILR holder would be subject to the returning residents provisions.
