Fantastic news cheekee
well done and congratulations to you both after all the hard work

Is this her 1st time here to the UK?
Could you please tell me more about what happen once your wife got her visa, what I mean is this....
What does this all mean about the 28 days and a time limit for your wife to come to the UK and letting the visa officials know the date of her departure, which is already booked and that the ticket is paid for even before if and when you will know if she will or when she get visa or not?
This part I cannot get my head around
Regards
