Hi,
How long have you been in the UK ?
If 5 years next year you can apply to become UK citizen,which would take additional 6-7 months.So,your wife would have to reapply and I would imagine that would be treated as new application.After period of 2 years she could get ILR.
So, roughly it would take more than 3 years.Is it worth all the hassle?Iam not so sure.

Regards

If you have ILR:
- your wife could go to the States and get an Entry Clearance valid fr 2 years (in the UK law, as you have ILR - so you are considered present and settled in the UK).
- during this 2 year time, you get your british citizenship
- then after 2 years your wife get ILR as well, and after 1 more year she can apply for British citizenship because she is married to a british citizen.
Not worth the hassle and the money spent with that, in my opinion!

 

She already have 5 year residence/family permit!
