mmmab,
From what you have said your wife is applying a spouse visa.
Two key issues are finances and accomodation.
Without getting into detail (your case doesn't need), you need to provide evidence that you can support your wife without recourse to public funds. In principle you need to clearly show the ECO that your income/cash flow is sufficient. The meaning of sufficient in numbers is approx £106 per week disposable income for a couple.(2011/2012)
Savings are certainly a good thing, but the real key is adequate cash flow to prove you are not living beyond your means.
The actual amount that will show in your current account is not critical, but please try to avoid submitting statements that are overdraw, as this will require detailed explanation to prove your position. Bear in mind the ECO is not aq qualified accountant, but does have enough experience and knowledge to know if the financial position is viable or not.
Any specific questions just fire away. There are many members all willing and able to advise.
