Which is why I recommended she apply for British citizenship. If the threadstarter ever plans to go back to the UK he would need to apple for new residence permits etc. and if his wife wanted citizenship it will be a lot more expensive and more difficult!

I think you can still apply for citizenship even if you aren't resident in the UK, I mean I guess she didn't tell anyone she is leaving the country? I'm sure you can use your parents address or something but it really does help if your wife is an EU citizen not just for this but for most walks in life
