Hiya Nick,

Yes regarding the dates your wife is here on the 5 year route which means extension of her current visa which is FLR(M).

My wife just over a year ago applied for her extension on this route and was pretty straight forward as long as you meet all the relevant criteria eg: financials ect.

Regarding shipping the missus home have no fear that won't happen especially now you have a little nipper in tow, I am sure others will add their input...
