usually the UKBA-Manila Visa Hub will send an e-mail saying “your visa will be dispatched shortly” or "The decision on your visa application has been made, processed visa application has been dispatched to you via courier". They don't say if it is approved or denied, you won't know the result til you receive the passport.

If you supplied all relevant documents and a CLEAR reason for her to return before expiry of her visa then I'm sure it is granted Sadly as many here have said, Visitor visa is a lottery and quite hard to obtain these days. But nothing is impossible with HIM. Keep praying for the positive outcome. goodluck and Godbless!
