We are planning on bringing my wife.s brother and mother to the UK for a 6 month visit. The plan is that we will be financing the whole thing ourselves from the uk as their source of income is us!

I have quickly looked through the UKBA website and it seems we can finance this but I wondered if anyone has any idea of what the UKBA will be looking for in order to grat the visa? What sort of money will they consider reasonable to finance a stay for two people over 6 months? Are there any other things we need to consider? Anybody else done this who could advise?

Both my wife's brother and mother are coming as I believe my mother in law is not comfortable travelling alone.
